In recent years, as Chinese people pay more attention to environmental protection and energy conservation in home decoration, bamboo flooring with good thermal conductivity and strong deformation resistance has become the first choice for many home decoration in China. Due to the variety of bamboo flooring and the uneven level of specifications, consumers are likely to have a "black eye" situation when they are selected in the market. To this end, the author visited a number of bamboo flooring manufacturers, and found that there are many tips for purchasing bamboo flooring. Bamboo flooring should maintain stability. The most important thing is to see if the floor structure is symmetrically balanced. The symmetry is strong, the environment is less affected, and the deformation probability is low. It can effectively release the internal stress caused by thermal expansion and contraction or moisture. It can adapt to various global climates, especially for northern China. At present, there are three main types of bamboo flooring on the market: flat-press type, side-press type and medium-cross type. Consumers should choose flat-press type as the best choice when selecting bamboo flooring varieties. The influence of bamboo length on the quality of bamboo flooring is also very important. According to experts, the age of bamboo is not as big as possible. The best bamboo age should be 4 to 6 years. Bamboo is too tender and too old to affect the stability of bamboo flooring. The smoothness of the bamboo floor surface is the main factor determining the appearance of the bamboo floor. When selecting the bamboo floor, the consumer should carefully observe whether the surface of the floor is damaged, whether it is peeling off the skin, whether there is a wormhole or the like. The bamboo floor containing wormholes is lurking in risk. If the wormhole contains unfeathered termites, it may hatch out termites after installation, resulting in serious home-loading pests, which cannot be purchased. (Liang Zhaowen)
MC NYLON is recognized as the most widely used and known engineering plastic in the current market. PA6 has the best performance, very tough, even at low temperatures, and high surface hardness, mechanical lower shock, and abrasion resistance. Combined with these characteristics and good insulation, and chemical properties, it has become common-level materials. It`s widely used in a variety of mechanical structures and spare parts. Compared to PA6, PA66 own the higher hardness, rigidity, better resistance to wear and heat deflection temperature. Temperature resistance from -40℃ to 110 ℃.
