in Cork: easy, but not easy
A miracle tree and the national symbol of Portugal - that’s what the cork oak is!
We are unfair to the traffic jam: it gets it from us all the time! “Stupid as a traffic jam,” “flew out
like a cork "... A cork evokes very unpleasant associations - an ear plug,
traffic jam. The exception is, perhaps, a wine cork. In fact cork is a very useful, environmentally friendly and beautiful material.

in the province of AlgarveTo the evergreen cork oak (Quercus suber), supplier of bark that is famous
we were treated with respect as a “cork” already in antiquity:
Pliny the Elder mentioned
in his "Natural History" that in ancient Greece cork trees were dedicated
Jupiter and were considered a symbol of freedom; only priests were allowed to cut them. "Father
botany" the ancient Greek philosopher Theophrastus described the properties of cork as a miracle
oak tree to restore the bark after it is removed.
Cork grove in the Algarve
It's hard to say which is the greater miracle - the ability of cork oak to regenerate or
the unique properties of its bark. The structure of cork can be compared to a honeycomb.
which does not contain carbon dioxide. Cork is one of the lightest solids, it durable,
elastic, resilient, can shrink under pressure and restore its original
shape, does not allow heat, sound, liquid, gas to pass through. The cork does not sink in water and does not support
combustion, does not absorb odors, is resistant to friction.
Old balsa tree
Cork has been used since time immemorial, it was used to make sleeves for jugs,
fishing floats, soles, ship tackle. The finest hour of the traffic jam has come,
when important discoveries were made in the field of wine storage: in the 17th century, wine
moved from barrels to bottles, and at the turn of the 17th and 18th centuries bottles began to be corked
traffic jams The honor of this discovery is traditionally attributed to the French monk
Benedictine Pierre Perignon, who was engaged in the production of champagne.
(Although the name of the monk-winemaker is immortalized in the famous champagne brand "House
Perignon", he is not the first who thought of corking a bottle of wine,
but let's not deviate from the topic).
The only drawback of wine stoppers was that long-term storage of wine
they dried up. Finally, at the end of the 18th century, pot-bellied wine bottles “lost” so much that
that it became possible to store them lying down. A tightly fitting plug, in contact with the liquid,
could remain elastic for many years; winemakers could not have asked for anything better.

Cork is mined and processed wherever cork oak grows - in the south-
western Europe and North Africa, but unconditional leadership (more than 50%
production) belongs to Portugal, followed by more than twofold
follows Spain. About a third of our planet's cork forests, about 70 million
trees, grows in Portugal, mainly in its southern regions of Alentejo and Algarve. Here
ideal climate for cork oak: moderately rainy autumn, mild winter, hot and
dry summer, suitable soil and altitude (400-500 meters).

as the Portuguese painter king Carlos I did in 1905. In 2011
The Portuguese Parliament, on the initiative of public organizations, unanimously approved
draft resolution to give the cork oak the status of the National Tree of Portugal,
along with symbols such as the flag and coat of arms.

Cork oaks are very beautiful. Low (up to 20 meters), wide spreading
crowns, they seem to grow in breadth. The ocher-red trunks of the newly liberated
from the bark of trees are adjacent to darker trunks of oak trees growing bark.
Each tree has a number written in white paint: 4, 7, 8... What does this mean?
The cork oak allows a person to cut off its precious bark only at certain
conditions. Firstly, the tree from which the bark is removed must be at least 25 years old. Yes
and then the first bark of a young oak, which is called “virgin” (cortiça virgem), is not tall

can it be removed? Only in 9-10 years! Inscriptions on tree trunks are

Cork is a completely waste-free production. All that remains are strips of bark
after the wine corks have been cut out, it is ground into cork chips,
which is pressed into blocks using an adhesive mixture, cured and cut into
plates of various lengths, thicknesses and qualities. And what of these plates is not

soles, insoles, packaging material.

Modern designers increasingly value not only the lightness and strength of cork, but also its
beauty and decorative expressiveness. Made from the thinnest, up to 4 mm, layers of cork “fabric”
they make original and not cheap things. Portuguese store windows
fill cork umbrellas, bags, wallets, purses, toiletries, cosmetic bags, pencil cases,
eyeglass cases, hats, caps, shoes, slippers, belts, ties, women's jewelry, covers,
keychains, lampshades, dishes, boxes, fans, photo frames, postcards.
Showcases with cork wonders
"Save a tree, buy a cork"
In stores with cork wonders you can often see a poster “Save a tree, buy cork” -
"Save the tree, buy the cork." Cork oak with its ability to regenerate -
an ecological dream, a completely renewable natural resource. Carefully extracting
cork, man does not cause any damage to nature, and at first glance it may seem
that Portugal's cork forests are not in danger. Here already in the Middle Ages
there were laws protecting cork trees. Nowadays, spoilage and illegal
cutting down trees is punishable by a multi-thousand-dollar fine and deprivation of the right to use
land for 25 years. Many landowners believe that cork protection laws
trees are even too strict: so as to cut down dried or infected
tree pests require government permission. Bye, with true
Portuguese slowness, this resolution comes, the sick tree has time
infect neighboring oak trees.
Such harsh laws had to be adopted after the deforestation of

Dried cork oaks can be seen more and more often.
Winemakers dealt another blow to cork oak. More than 200 years ago it was precisely the need

plastic, synthetic ersatz, metal leads to a reduction in production. Although
many winemakers still believe that only a solid cork is worthy of corking
bottles of vintage wine, prospects for the fishery - and with it the cork oak -
alarming. After all, as soon as forests lose their economic value, local residents
will stop caring for them and protecting them from devastating forest fires. Loss
oak trees, in turn, jeopardizes one of the most important ecosystems in Europe, threatening
region due to desertification, the disappearance of rare species of animals and plants, including
including the Iberian lynx, which likes to make a den in the hollows of old cork trees
trees.
Moreover: cork oak, especially in the first decades of life, when there is intense
bark growth, is the record holder among plants for the accumulation of carbon, it absorbs it in five
times more than other trees, and how important is this for reducing greenhouse emissions
gases into the atmosphere, there is no need to explain. However, what kind of troubles can arise in
world because of an ordinary wine cork... The motto “Save a tree, buy a cork” can be clarified:
"Save the cork oak, buy the cork." However, perhaps everything is not so bad: recently
decade, a “cork renaissance” has emerged among winemakers, and one can increasingly hear
from them that nothing can replace natural cork!
When uncorking a bottle of wine, pay attention to the cork: how solid, solid,
with manufacturer’s logos, or pressed from cork chips, or maybe even
synthetic. And if you come across a real beautiful cork, do not rush to throw it away.
After all, cork is easy, but not at all simple!
An ordinary bottle stopper has many possibilities. It is often used in the process of finishing premises. From cork you can get good finishing materials that have many positive qualities.
For example, cork flooring is currently one of the most prestigious. Made from balsa oak, cork is the hardest and lightest flooring available. It has reduced thermal conductivity and an increased level of sound absorption.
More than half of the world's cork products are made in Portugal.
Raw materials for the production of cork coverings
Interestingly, the production of cork flooring does not require cutting down trees. As a rule, this involves removing a layer of tree bark. This is done very carefully to allow the tree to grow further and to allow bark to grow. However, the cork oak must grow for almost a quarter of a century before the first harvest.
And the bark is removed from such trees every 9-10 years. Cork oak grows up to 160 years. Therefore, one tree is used almost 15 times to remove bark. It should be noted that cork production is very economical and rational. Recycles the smallest particles of material.
For example, in the process of producing cork boards for the floor, even granulated cork, which is waste from the production of bottle caps, can be used.
For example, in rolls, plates, granules. This type of material is not used as a finished floor. However, it can be used as a substrate. Eg, . This material has good sound insulation and is used for additional insulation of floors. Various niches and voids are also filled with cork crumbs or granules.
The second type of cork flooring is adhesive cork flooring or adhesive cork flooring. Such materials are produced in the form of tiles of different sizes. Standard sizes of square tiles: 300x300, 450x450 mm, rectangular - 450x150, 600x300 mm.
Cork tile materials for floors can be made with an additional top protective coating.
These cork tiles come in a variety of colors, so you can create original patterns and designs from them.
Adhesive floors are also used in rooms with high humidity. They are quite resistant to water.
For example, you can make cork floors from tiles in a toilet or bathroom. Floating floors made from cork are called cork flooring. These are small pieces of cork that are glued onto MDF. Cork parquet has a standard size of 900x185 mm. This parquet is quite easy to install; it is done according to the laminate principle, i.e. with a locking system.
It is better not to use parquet cork floors in damp rooms, because MDF swells.
The top layer of cork floating floors is also made from decorative cork veneer and expensive wood. Such materials are top coated with several layers of varnish or protective vinyl film. Pressed cork is used as the middle layer.
Cork finishing materials
There are several options for producing finishing materials from cork.
1. Solid cork veneer is used for the most expensive type of covering (ceilings, walls, floors). Entire collections of coatings are made from this material, for example, cork floor tiles. Selected according to the color of the individual components.
2. Agglomerate made from cork chips. The crumbs are pressed under the influence of elevated temperatures into single layers of floor covering. It is the cheapest material. All small waste from cork production is used for it.
3. Combination of agglomerate and large veneer. Quite a good compromise solution. Large and small parts of cork material are perfectly combined, providing good quality products.
Despite the difference in price and variety, these options do not differ in wear resistance and mechanical properties. They differ in appearance and the use of not very environmentally friendly plasticizers in the process of working with crumbs. Therefore, only veneer is considered an absolutely environmentally friendly material.
Benefits of cork
Cork boards have quite a few significant advantages, including:
— good sound insulation properties;
- they are not afraid of moisture;
— the cork is chemically inert;
— increased thermal insulation of floor coverings;
— cork floors are pleasant to the body, slightly springy and quite warm;
— the material does not rot;
— cork is not spoiled by rodents, microorganisms, or insects.
Flaws:
— over time, the protective coating of the cork wears off. In this case, updating of such coverage is required;
— when furniture stands for a long time, dents remain on the cork floor;
— the cost of veneer is quite high. Agglomerate is significantly cheaper.
Peculiarities
Floor-standing ones have a honeycomb structure, due to which they are able to perfectly retain heat, do not allow sound to pass through and have springy qualities. Traces from the pressure of heels remain on cork floors: cork does not slip and is able to return to its original form.
This coating has a positive effect on the musculoskeletal system of people. Cork floors have bactericidal and antistatic properties, which is why they are widely used. In addition, it is a very prestigious and beautiful finishing material.
Options for the front layer of cork coverings
Currently, manufacturers of cork flooring offer several options for finishing the top face layer:
— applying a thin layer of veneer to a base of pressed cork to improve the decorative properties of the material;
- the same layer of veneer, but additionally coated with several layers of varnish to increase wear resistance;
— the veneer layer can also be covered with a layer of transparent vinyl film, which has increased wear resistance;
- sometimes a layer of expensive wood veneer is applied to a pressed cork base, and the top is also covered with vinyl film.
The scope of use of cork flooring is quite wide. They are used in various premises: in public reception areas, airport and train station buildings, studios, offices, supermarkets, restaurants and cafes, video and photo salons.
However, cork floors are more often used in residential areas. They can be used in rooms with different purposes. They are ideal coverings for bedrooms, children's rooms, and living rooms.
Cork is also quite suitable for bathroom and kitchen floors. However, for such rooms only adhesive plugs are used; MDF-based parquet is not suitable.
Laying technology
To install cork flooring, some preparatory work is required. Any cork coatings will be durable and reliable only if the bases are well prepared.
The surface must be dry, clean and level. It can be metal, concrete, wood, etc. On uneven surfaces, it is possible to use self-leveling mixtures. Sheets of fiberboard or plywood of small thickness are often additionally laid on the base of the floors, securing them with screws or nails along the entire perimeter.
It is important that the joints of these sheets do not coincide with the joints of the cork covering.
It is best to use a special glue for gluing cork tiles, which is recommended by cork manufacturers. In some cases, it is possible to use PVA glue, but some types of it can lead to deformation or shrinkage of the tiles. Therefore, such adhesive is more often used for uncompacted slabs that have vinyl protection at the base.
Before laying cork products, it is recommended to keep them indoors in packages for about a day. The installation procedure is performed at a humidity of 50-60 percent and a temperature of 18-20 degrees.
As a rule, cork tiles are laid from the center of the room to its walls. The tiles must be sorted in advance by texture (grainy or smooth) and color. By laying grain tiles in a cross pattern, you can achieve the appearance of a single surface.
It is possible to alternate grained and smooth tiles.
First, the floor pattern is laid out completely dry, without using glue. In this case, you can slightly adjust the placement of the tiles to leave the same space on each side. Thus, the edges of the cut tiles look like a beautiful frame.
Let's start gluing the tiles. Glue is applied to the base and tiles. It needs to be allowed to dry a little. Basically, the time is indicated on the packages. First, several tiles are glued in one direction. Then the remaining tiles are glued from them without gaps.
After the glue dries, the rag is moistened with white spirit. After laying the tiles, you can walk on them immediately. Furniture is installed no earlier than a few days later
It will also be useful for repairs.

II. Presentation of program material.
Forests occupy an area of over 700 million hectares in our country. Despite such enormous forest wealth, everyone must treat the forest with care, since it significantly affects the climate, flora and fauna. In addition, the forest is of great economic importance. Its main product - wood - is used in construction, furniture, match production, chemical industry, etc. Forest resources in our country are protected by law.
oLet's compare the properties of wood and materials such as metal and stone.
We come to the conclusion that wood is a light, durable material that can be easily processed with cutting tools and has a beautiful appearance.
At the same time, we identify its negative qualities: easy flammability, warping when drying, rotting.
o What tree species do you know and what types are they divided into? Deciduous and coniferous.
Trees with foliage are called deciduous, and those with needles are called coniferous. Deciduous trees include birch, aspen, oak, alder, linden, etc.; Conifers - pine, spruce, cedar, fir, etc.
o What is a tree made of?
From a trunk, root, twigs, leaves or needles Wood as a natural structural material is obtained from tree trunks by sawing them into pieces Fig. 3
The tree trunk has a thicker part at the base and a thinner part at the top. The surface of the trunk (Fig. 3) is covered with bark (7). Bark is the “clothing” for a tree; it consists of an outer cork layer and an inner bast layer. The cork layer of bark is dead. The bast layer (6) is a conductor of the juices that nourish the tree. The wood of the trunk consists of many layers, which are visible in the section as growth rings (4).
o What can you learn from them?
You can determine the age of the tree. The loose and soft center of the tree is the pith (1). Heart-shaped rays extend from the core to the bark in the form of light shiny lines (2). They serve to conduct water, air and nutrients inside the tree. Cambium (5) is a thin layer of living cells located between the bark and wood. Only as a result of the activity of the cambium does the formation of new cells occur. " Cambium" - from Latin " exchange"(nutrients).
To study the structure of wood, three main sections of the trunk are distinguished (Fig. 4). The cut (1) running perpendicular to the core of the trunk is called the end cut. It is perpendicular to the growth rings and fibers. The cut (2) passing through the core of the trunk is called radial. It is parallel to the annual layers and fibers. Tangential cut(3) runs parallel to the core of the trunk and is some distance away from it.
Wood species determined by their following characteristic features: texture, smell, hardness, color. (Show how to identify wood types using the poster.)
The disadvantages of wood are also the following: knotiness(Fig. 5p), wormholes(Figure 5.6). They limit the use of wood in industrial production, but can be valuable in the manufacture of decorative products.
Fig.5Let's move on to considering lumber and wood materials.
When longitudinally sawing tree trunks on sawmill frames, various lumber is obtained (Fig. 6): beams (a, b), bars (c), boards (d, e), plates (f), quarters (g) and slabs (h)
Fig.6Lumber has the following elements: face, edge, end, rib. (Indicate on the poster. Plywood is widely used as a construction material.)
oHow do you get it?
By gluing three or more thin sheets of wood on top of each other - veneer. Veneer translated from German - " sliver"The veneer is cut (peeled) with a sharp knife of a special peeling machine while rotating a log about 2.0 m long (Fig. 7). At the same time, the log, like a roll, is rolled out into a veneer strip. The veneer strip is cut into square sheets, which are dried in dryers, spread with glue and stacked on top of each other so that the direction of the fibers in them is perpendicular to each other. The sheets are glued together under a press.
Plywood is stronger than wood, almost does not dry out or crack, and bends and processes well.
o Where is it used?
In construction, furniture manufacturing, mechanical engineering, aircraft manufacturing.
o You've probably heard the word chipboard, but what does it mean?
Particle boards. They are obtained by pressing and gluing crushed wood in the form of shavings, sawdust, and wood dust. The slabs are made with a thickness of about 10-26 mm. They are durable, almost do not warp, and can be processed well with cutting tools.
o What are they made from?
Furniture, doors, partitions, walls, floors. However, over time they release substances harmful to health, so they are not recommended for use in residential areas.
o What is fiberboard?
Fiberboards. They are pressed into sheets of wood pulp that has been steamed and crushed into individual fibers. They have a pleasant gray color, smooth surfaces, and bend, like plywood. They are used for interior decoration: cladding walls, ceilings, floors, in the production of furniture and doors.
o What is the common disadvantage of plywood, chipboard and fiberboard?
They are afraid of dampness.
Sh. Practical part
1. Students cut a block of soft wood (pine, linden) along and across the grain with a regular knife. As a result of this operation, they come to the conclusion that wood is easily split along the grain with little effort, but it is impossible to split across it, even with great effort.
2. Students try to identify types of wood from samples, look at samples of lumber, plywood, chipboard and fiberboard.
Check whether the samples can be easily processed with any tool (file, hacksaw, etc.).
IV. Final part.

Add our website to your social network:If quite recently the word “cork” was associated only with a bottle cap, now the situation on the finishing materials market is making its own adjustments to the vocabulary of the average person. Cork is increasingly becoming a full-fledged owner of floors and walls, striking with its unusual design and performance characteristics.
What is a traffic jam?
The countries of northern Africa and southern Europe have given people trees unique in their properties - cork oaks, which have been supplying exotic material for various needs for many centuries. The history of such plants goes back more than sixty million years, and Portugal takes the honorable lead in growing cork trees. Real cork is not a cheap material. This is due to the relatively long period of ripening of cork oak bark - about 25 years. The first removal of the bark is of a technical nature, since it is hard and friable. To obtain an ideal plug, the cutting procedure is repeated, but the periods of bark removal are repeated no more than once every 9 years, so as not to damage the tree.
The honeycomb structure of cork is unique, consisting of thousands of micropores impregnated with suberin, a natural cork substance. Thanks to this unusual composition, cork also gains extraordinary properties - excellent thermal insulation, comparable to brickwork, good sound and vibration absorption. The durability of cork, bactericidal and antistatic properties, and the absence of treating trees with herbicides make this material one of the most environmentally friendly finishing coatings on the market today. Due to its properties, cork is ideal for interior decoration, rivaling even the recognized authority of parquet.
Types of cork coverings
Of course, cork intended for walls or floors differs in its characteristics, as it is used with different degrees of intensity. Cork flooring is usually multi-layered, the base is pressed cork, and the front layer is a veneer of cork or other valuable wood species. In order to give the material strength and wear resistance, the surface of the cork is coated with a varnish or vinyl layer. Vinyl cork flooring will withstand heavy loads, so it is suitable even for use in public spaces, while varnished coating is best used at home with not too high traffic.
There are two widely used options for finishing cork floors - adhesive coverings and floating cork floors. The first option is made in the form of tiles of different sizes, but its thickness is always the same. Using different combinations of tiles, you can create designer floor options using special glue.
A floating cork floor consists of panels based on MDF, on the inside of which a cork layer is glued, and the front surface can be either decorative cork or wood veneer, varnished before or after installation. A floating cork floor is not fixed to the floor, but is glued together using locks that connect the tiles to each other. Laying such a floor on a substrate is quite simple even for an inexperienced craftsman. But such a coating, unlike adhesive cork flooring, is not suitable for use in rooms with high humidity.
There is also technical cork, which serves as a heat insulator, a substrate for laminate flooring, for example, available in the form of rolls, plates or granules.
One of the few disadvantages of cork flooring is its price. It is quite high and depends on the thickness of the layer of the cork itself and the type of coating on the front side. The softness of cork also sometimes causes the formation of dents from furniture, which do not always even out over time, no matter how much its sellers convince you otherwise.
For most of the above characteristics, cork remains the undisputed leader, which allows us to see more and more new types in the range of this material every year. When choosing a cork for the floor or walls, realizing some of its disadvantages, the buyer often understands that it has many more advantages.
