Cork is collected from the oak skin layer, the scientific name of quercus variabilis, because of its soft texture, so commonly known as cork, its main chemical composition: suberin 45%, 27% lignin, cellulose, 12%, 6% tannin, wax 5%, other 5%. When the cork is peeled from the tree the general thickness is 4-5 centimeters, the thickest can reach 10 centimeters above, the section has natural grain, show the light soil yellow. Today I want to tell you something about the tree bark from the home and abroad. What is the difference between the soft bark that we usually talk about?

1, the geographical distribution of cork, cork mainly live in the west coast of the Mediterranean basin, the distribution in seven countries: Spain, Portugal, France, Italy, the luo elder brother, Algeria, Tunisia. Portugal has 30 percent of the world's cork forests, producing 50 percent of the cork raw materials and consuming 75 percent of the world's raw materials.

The best quality grows in Portugal. The cork from these countries can still grow, but the effect of bark growth is very different, the bark is very thin. Many countries have tried to introduce the tree in their country before, and the trees grow there as usual, but the bark is not good. Are not successful reason is because the living conditions of the not adapt to, because the growth of the cork forests not only have the demands of climate condition, soil with certain nitrogen content more requirements, and are rich in potassium, PH value to 5/6. The ideal growth environment is between 100 and 300 meters above sea level, with annual precipitation of 400 to 800 millimeters. The annual temperature is no less than 5 degrees, and the most important is the constant moisture of the Atlantic ocean.

Qinling area have such trees transplanted in China, although their latitude, but due to the reason of soil and climate, the thickness of the bark is not as good as the Mediterranean, the basic properties of the bark of six to one, in particular, in the strength and toughness, in terms of colour and lustre and purity and Portugal, compared with the naked eye in the clear. Due to the differences in chemical and physical structure in the bark, the difference of the grafted cork in comfort, quiet, waterproofing and heat preservation is revealed.

2, cultivating in a different way If the single from the internal structure, internal and overseas cork bark of cork bark is no different from, belong to the same, especially to make the floor, but there is no difference. The only difference is to nurture a different way, the domestic cork is a natural forest wild forest, and foreign cork forests belong to artificial cultivation of economic forest, is a wild, a is artificial breeding. So produce the bark of cork internal and overseas cork bark bark will exist congenital dysplasia, the thickness, sand inclusion, holes and other differences, as we have high and low fat, but ultimately. If the application is properly classified, cork products made from domestic cork bark are no worse than foreign ones.

Although our domestic cork resource comprehensive utilization and development of nearly 200 in the evening than abroad, we both in the understanding degree, technical support, market operation, etc and foreign gap still exist, but that doesn't mean we Chinese cork resource is always worse than abroad. Dongguan yingfu cork products co., LTD., founded in 1998, is now the leader of cork products in China.
