Oak is mainly produced in Europe and North America and is currently produced in large quantities from Russia and the United States. In China, Jilin, Liaoning, Shaanxi, Hubei and other places are distributed with eucalyptus, which is similar to oak, with similar texture. In English, it is generally called oak with oak. China's Jilin and Liaoning have had large productions. Hubei Shennongjia and Shaanxi also have a small amount of eucalyptus production. However, the domestic production of sorghum timber is relatively short, and domestic production is not formed. It is not an ideal furniture material. At present, resources are limited, and due to forest protection measures, China has produced very little. Domestically produced eucalyptus quality materials are rare, and superior oak still needs to be imported from abroad. The excellent materials cost nearly 10,000 yuan per cubic meter, which is also an important reason for the high price of oak furniture. Advantages of oak furniture: 1. It has a relatively distinctive mountain-shaped wood grain, and the touch surface has a good texture. 2, the toughness is very good, can be processed into a variety of curved shape according to needs, quite aesthetic. 3, the texture is solid, the finished product has a firm structure and long service life, and is used in the production of many ancient door and window lattices. 4, higher grade, suitable for the production of European furniture, Chinese classical furniture, thick and real, with majestic and dignified mahogany furniture, but the price is lower than mahogany furniture. 5, the oak texture is fine, there are more intrusions in the tube hole, not easy to absorb water, corrosion resistance, high strength, used in Europe and America to store red wine. Disadvantages of oak furniture: 1. There are relatively few high-quality tree species. Most of them are imported from Russia and the United States, and some are imported from Turkey, Austria, Germany and Canada. There are many other regions in Europe and America, but imports are rare. 2, usually imported oak sheet has been subjected to strict drying treatment abroad, with good stability. Some manufacturers directly import logs from abroad and cut them by themselves. At present, many oak furniture manufacturers in China have high stability in oak furniture. However, due to the hard texture of the oak, it is more difficult to remove the water. The furniture made from the clean water may begin to deform or shrink and crack after a year and a half. 3. The phenomenon of replacing oak with rubber wood in the market is widespread. If the customer's professional knowledge is insufficient, it directly affects the interests of consumers. Fraxinus mandshurica is an ancient remnant plant. Although it is widely distributed, it is mostly scattered and is a national level II key protected wild plant (approved by the State Council on August 4, 1999). Due to over-cutting, the number is decreasing day by day. The ash tree sounds very beautiful wood name, which is easy to reminiscent of the willow tree growing in the waters of the south of the Yangtze River. In fact, ash is not a literally understood willow tree, which is commonly known as ash. Tree species that grow faster and have a longer lifespan in hard-leaved tree species, with a tree age of 250 years. The wood is tough, dense and elastic, resistant to decay and water, and the texture of the ash is straight and beautiful. The wood is tough and can be used to make all kinds of furniture, musical instruments, sports equipment, vehicles, boats, machinery and special building materials. The advantages of ash furniture: 1. The cut surface is very smooth, and the paint and the sticky property are also very good. Suitable for dry weather, with minimal aging and small changes in performance. 2, ash processing performance is very good, can be fixed with nails, screws and glue, can be dyed and polished to achieve a good surface effect. 3, ash has a tough material, beautiful texture, also has excellent overall strength performance, good shock resistance and steam bending strength, is a good material for the production of furniture. Extended reading: the difference between rubber wood and oak furniture Disadvantages of ash furniture: 1. There is no heartwood anti-corrosion in ash, white wood is easy to be eaten by powder beetle and common furniture beetle. It is not easy to dry and easy to produce cracking. 2, ash solid wood furniture, large deformation, made of solid wood, multi-use small wooden block splicing, large pieces of wood shrinkage deformation, not suitable. Some ash furniture is basically the main frame of ash wood, and the large area is afflicted with ash wood, which is also due to the large deformation and shrinkage of ash. Compared to the two kinds of wood, one is exhausted and endangered, one is rich in resources, and it should be that the price of oak is cheaper, but in fact the ash (this refers only to the small size of ash) is not as high as oak. The problem is that because oak is an imported material, the original production cost is not low, coupled with high tariffs and freight rates, and the increase in domestic demand has caused its price to rise. With the depletion of resources, the market has been difficult to find large-scale wood, no choice, people have gradually abandoned their preference, and turned to other wood varieties, the demand is getting smaller and smaller, The price naturally cannot rise. Therefore, from the perspective of price, the choice of ash is more advantageous, but from a sustainable perspective, you should choose oak furniture. Considering the color texture of the wood, both materials are excellent, the color of the ash is more stable, and the white oak is cleaner and more delicate. Rubber Damper, also known as Shock Absorber, Isolator, and NBR grommet, NBR is a unsaturated rubber copolymer with polar unsaturated carbon chains, which is copolymerized by propenenitrile and butadiene, according to propenenitrile content from low to high, the higher the resistance to oils but the lower the resistance to cold. Oil resistance is the greatest advantage of NBR elastomer so it has excellent resistance to petroleum base oils and non-polar solvents but poor resistance to polar oils and polar solvents.

Nitrile rubber (NBR, Buna-N) grommet provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.
