Recently, Typhoon ' mountain bamboo ' ravaged the southeast coast of China, the media reported that the ' mountain bamboo ' lifted seawater flooded the city, the water faded, the streets leave full of foam, drink bottles and other rubbish. Netizens commented that the rubbish, which had been dumped by humans in the sea, was ' also ' given to humans after a typhoon, ' it is the nature's revenge on humanity '. But in fact, human beings are not powerless against these ' white trash ', which is the area where chemical technology can be a skill.
Reporter learned that at present, there is such a chemical products can make plastic products in the short term degradation, to solve the garbage siege to create opportunities, it is a new chemical intermediates--ε-lactone. In recent years, the chemical industry in the new environmental protection materials continue to exert force, biodegradable, ecological non-toxic high-end plastics industry attaches great importance, one of the most concerned about is ε-lactone.
Reporter learned that this new chemical intermediates have different from other similar intermediates unique properties, it has very high activity, excellent biocompatibility and good biodegradability. Hunan Poly-Ren chemical new material Technology Co., Ltd. Chairman Wang Yanyu to reporters, ε-is completely non-toxic to the human body harmless, can be used to manufacture artificial bones, artificial joints, artificial blood vessels and heart stents, etc., currently in foreign applications.
At the same time, this product also has good biodegradability, with its raw materials made of poly-hexyl ester plastic under natural conditions can be completely degraded to carbon dioxide and water, for the maintenance of ecological environment has great help. In fact, the use of ε-is not only for environmental protection, it also has an eye-catching performance in improving the performance of chemical products. Wang Letter Yu said that ε-can enhance the performance of coatings and polyurethanes and other chemical products.
When used in waterborne and solvent-free coatings, ε-can significantly increase the toughness, adhesion and aging resistance of acrylic and epoxy coatings, while in the polyurethane industry, ε-can compensate for defects in traditional raw materials. Wang Letter Yu told reporters, China's polyurethane industry is widely used polyether polyol or polyester polyol and two isocyanate reaction to manufacture polyurethane, but no matter polyether polyols or polyester polyols have obvious defects: the former, although the elasticity is better, but the tear strength and oil resistance is poor; the latter, although strong oil resistance, but the elasticity and toughness are not enough .
The poly-hexyl ester Polyol has strong performance in oil resistance, water resistance and strength. In addition, the military, aerospace and other fields also provide a stage for ε-lactone. According to the introduction, the ship's outer material has ε-to participate in, when a large number of shells and other marine life adhesion, can be a layer of ' molting ', so in three years do not need to return to the pier for maintenance, saving a lot of manpower and resources.
In the military field, submarines, rockets to better enhance the tightness, but also need to ε-the help of Lactone. ε-has so many excellent properties, how is the market performance of this product? Although the current China has broken this high-end new material technology Monopoly, the successful realization of domestic, but the application of ε-lactone in the domestic is not smooth sailing.
Wang Letter Yu to reporters that the most important thing is to make the product as soon as possible in the downstream industrial chain to promote the use. It is understood that this high-end new material costs relatively high, so downstream acceptance of some obstacles. Wang-Yu believes that the key to solving the application of the downstream market is ' opposite the line ': On the one hand is the national environmental protection policy upgrade and residents of environmental awareness of the promotion, on the other hand is ε-lactone production enterprises to continuously upgrade the technical level, so that production costs further reduced.
