As soon as the beautiful and high-quality cork decorative board appeared on the market, it attracted the attention of the decoration industry. This novel plate production technology was immediately introduced, and the products were gradually put on the market, which not only saved a lot of foreign exchange for the country, but also promoted the domestic decoration industry to go up and down, meeting the increasing demand for interior decoration.
Cork products include:
①Natural cork products. After steaming, softening and drying, it is directly cut, punched, and turned into finished products such as plugs, pads, handicrafts, etc.
② Baking cork products. The leftover material of natural cork products is crushed and then compressed and molded, and baked in an oven at 260～316℃ for 1～1.5 hours. After cooling, it becomes cork bricks for low temperature insulation. It can also be manufactured by superheated steam heating method.
③Cemented cork products. Cork fine particles, powder, and adhesives (such as resin and rubber) are mixed and pressed to form cemented cork products, such as floor veneers, sound insulation boards, heat insulation boards, etc., which are widely used in aerospace, shipbuilding, machinery, construction, etc.
④Cork rubber products. It is made with cork powder as raw material and the amount of rubber is about 70%. It has the compressibility of cork and the elasticity of rubber. Mainly used as high-quality low- and medium-pressure static sealing materials such as engines, and also used as anti-vibration, sound insulation, friction materials, etc.
Everyone is familiar with medicine stoppers made of cork, moisture-proof cork stoppers and mechanical seals; however, cork, as a high-end and trendy facing material, may be poorly understood or unknown. In fact, cork decoration has been popular in advanced countries such as Europe and the United States for a long time. According to experts, it has many excellent properties such as sound absorption, moisture resistance, abrasion resistance, fire resistance, heat insulation, and corrosion resistance. It is economical, practical, and environmentally friendly. It is an ideal new type of decorative material.
Cork is the outer branch of the cork oak bark. This tree can only be peeled once in 25 years, and the tree continues to grow thereafter, peeling again every 10 years. The world’s cork producing areas are mainly distributed in Shaanxi and a few provinces on the same latitude. At present, the world’s annual output of softwood is 350,000 tons, Portugal accounts for more than 50% of the world’s output, China’s annual output is 50,000 tons, and Shaanxi and neighboring provinces account for more than 65% of the national output, and they are relatively concentrated.
The microscopic cell structure of cork is composed of many cork cells with hexagonal prisms in cross section, arranged in a honeycomb shape, with a density of 40 million per cubic meter. The static air volume in the cell cavity occupies 70% of the unit volume, and the specific gravity is 0.24. Therefore, the cork is a lightweight material, and the adjacent cells are filled with resin to make each cell an airtight and liquid impermeable sealed unit. It is precisely because cork has a special cell structure and chemical composition that it has good open air cushion elasticity, shock absorption function, and excellent sound absorption, spacer, corrosion resistance, moisture resistance, wear resistance, fire resistance and other properties.
The thermal insulation effect and thermal insulation performance of cork is five times that of the original, and 20 times that of brick-concrete structure. The sound insulation of the wall material made of cork maintains the indoor constant temperature and internal quietness. At the same time, cork is a wood material with “B2” level of fire resistance and self-extinguishing properties. It has been technically certified by the United States, Japan, Malaysia, Singapore, Europe and many other countries, making it a leader in wood resistant materials.
The good elasticity of cork makes it keep the synchronous change of the two after being stacked with the log, which solves the problem of cracking on the veneer wall and relieves the worries of deformation of the wooden veneer material. After scientific research and processing, they are made into pieces of cork. The surface layer is made of resin as a protective layer. It can imitate marble, cherry wood, granite, and red oak colors. The original cold hard wall and ground become warm and soft, and become more elastic, and the distance between people and space is getting closer. The walls and floors decorated with cork boards seem to be more coordinated no matter what kind of furniture, type of furnishings, and any color tone. The matching compatibility and lining form a perfectly unified picture.
Scientific and technological data verify this: Walls and floors decorated with decorative cork will have the following effects on the human body’s physiology and psychology. Once a person leaves the yelling environment, what he gets is tranquility and warmth. The cork decorative board keeps the bustling noise away, and the floor is soft like a carpet on his feet, which is relaxed and powerful. In the atmosphere, the fatigue after a day’s journey can be completely eliminated, and arthritis is rarely seen in this environment for a long time.
It is understood that the interior walls and floor decorations used in the construction of overseas private villas and urban gardens can generally be divided into three categories, latex paint, carpets and wooden floors, and the newly developed cork decorative panels are a new category. , There is a tendency to replace, the main reason is that it has many decorative functions, rich styles, and does not bring negative effects on the human body, so it is welcomed and loved.
There are many varieties and specifications of cork, which can be designed according to design needs, and a variety of patterns and colors can be assembled. And the construction is simple, just stick it directly on the wall or the ground. Cork decoration material advertisements are suitable for decoration and decoration of residential villas, restaurants, hotels, hospitals, libraries, kindergartens, gymnasiums, computer rooms, etc.
With the development of modern decoration industry, the materials attached to the walls and the ground pay more attention to the characteristics of environmental protection and health, and it is also required to greatly satisfy the harmony of human physiology, psychology and environment with people. The reality of cork decorative panels The function has far exceeded the traditional wallpaper, paint, PVC board, marble, etc., and its decorative effect is full of typical luxury and rich human touch. Therefore, it is a wonderful flower full of “green” sentiment blooming in the decoration world.
