Nowadays cars are more than mere means of transportation. More and more people are putting forward higher requirements on the additional performance of automobiles, and soundproofing materials are one of them. Many young people begin to carry out sound insulation modification on their own cars, so more and more manufacturers of car soundproof materials are used in the production, and the market competition of soundproof materials is also getting fiercer and fiercer. Many noise insulation materials manufacturers began to choose low-cost production of noise insulation materials, do not know this middle "hidden murderous."
General high-quality sound insulation materials are produced using butyl rubber, butyl rubber has the role of anti-shock damping effect produced by the sound-proof material performance is good, safe and healthy. However, the price of butyl rubber is high. Many price-waging businesses are hard-pressed to win market share if they use butyl rubber to produce soundproofing materials. Therefore began to fling other raw materials, asphalt is the most representative example:
Asphalt is a dark brown complex mixture of hydrocarbons with different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid with certain damping characteristics. It can not only meet the requirements of noise insulation but also greatly reduce the noise Raw material costs. However, bitumen is irritant to the skin and mucous membranes and has the effects of light poisoning and carcinogenesis. Long-term presence of asphalt in the environment, will cause dizziness, head swell, headache, chest tightness, fatigue, nausea, loss of appetite and other systemic symptoms and eye, nose and throat irritation, and even induced leukemia, skin cancer, lung cancer , And severe diseases such as stomach cancer and esophageal cancer. So for the sake of you and your family, do not choose cheap, sound-proof materials made of asphalt.
As far as noise insulation manufacturers are concerned, do not blind yourself to the benefits. If you want to reduce the cost, you should also choose a healthy raw material for the production of noise insulation materials. Maybe you would say that apart from asphalt, where there is cheap sound insulation material? Here, Xiao Bian to recommend a material for you: butyl rubber reclaimed.
Butyl reclaimed rubber is a kind of rubber product made from waste butyl inner tube, which retains the tightness, watertightness and damping properties of butyl rubber. It is an ideal substitute for butyl rubber. Butyl reclaimed rubber belongs to renewable resources, The price is about 1/3 of the price of butyl rubber, high-quality butyl rubber reclaimed rubber prices may be higher, but not more than half the price of butyl rubber, so for the production of sound insulation materials can significantly reduce the cost of raw materials.
