Cork has a series of excellent characteristics, such as low density, compressibility, elasticity, air tightness, water resistance, moisture resistance, oil resistance, acid resistance, shock absorption, sound insulation, heat insulation, flame retardancy, insulation and wear resistance, and is loved by thousands of people. Cork decorative materials have incomparable advantages over other decorative materials.
After natural aging for 6- 12 months, the capillaries between cork cells dried up and died, that is, thousands of dead cells with honeycomb structure were formed, and air was blocked in the cells, forming closed air bags. When subjected to external pressure, cells will shrink and become smaller, and the air pressure in cells will increase. When the external pressure is lost, the air pressure in the battery will restore the battery to its original state. This is also the principle that cork is "soft".
The composition of cork cell wall is different from that of common bark, which is mainly composed of complex higher fatty acid esters and a small amount of wax, terpene (an organic compound, mostly aromatic liquid, turpentine oil, peppermint oil, etc.) olefin resin, etc. Its chemical properties are very stable, it will not breed all kinds of insects and bacteria, and it will not react with polar substances such as weak acids and bases, so its health and environmental protection performance are beyond doubt. The finished or semi-finished products made of it have greatly changed people's living or working environment and improved people's quality of life.
