The performance of modified plastic raw materials is difficult to meet the different needs of different industries and fields. Therefore, plastic raw materials need to be modified in special working environments. The main methods include blending modification, copolymerization modification, composite reinforcement modification, and filling. Modification, nano-modification and surface modification technologies. Modification can increase certain aspects of the properties of plastic raw materials, such as wear resistance, impact strength, etc., thereby expanding the application range of plastic raw materials, reducing the use cost of materials, and improving the processing performance of plastic raw materials. PLASTIC, the scientific name of plastic material, is not a large amount of plastic, but it is a plastic that cannot be ignored. Plastic raw materials refer to a type of polymer containing an imide ring (-CO-NH-CO-) in the main chain, of which polymers containing a phthalimide structure are important. As a special engineering material, plastic raw materials have been widely used in fields such as aerospace, microelectronics, nanometer, liquid crystal, separation membrane, and laser. In the 1960s, all countries included the research, development and utilization of plastic raw materials as one of the promising engineering plastics in the 21st century.
Strictly protect the lawns for sports games. With the renovation of Tiantai Stadium, the quality of lawns will rise to a new level. The notoriety of "vegetable fields" that has been carried on them for many years has also prompted the stadium management to make up their minds to maintain lawns. One of the important tasks is, "After changing the lawn this year, we will resolutely prohibit trampling on the lawn at will, and we must not be like the past." Zou Jun, "The sports meeting can be held in the stadium. But this year, no matter who comes to contact, I will tell them that if you want to use the stadium, it’s no problem. You can use these facilities like the track and chairs, including the athletes’ entrance ceremony. They can only be on the track, and never enter the lawn.

The aromatic ring structure in the molecule of the plastic raw material belongs to the aromatic plastic raw material. If only the diamines or dibasic acids of synthetic plastic raw materials are used as aromatic II. 2. Utilization of recycled materials For primary or secondary clean plastic raw materials that are free of impurities and decomposers, they can be crushed. It can be used directly or mixed with new materials, and the mixing ratio is generally not more than 25% of the new materials, so as not to affect the performance. For recycled materials that have been regenerated more than 5 times or added with coloring agents, generally not mixed with new materials, mainly to prevent color difference. Regardless of whether it is a single recycled material or a recycled material mixed with a new material, it must be dried in accordance with the regulations before it can be put into molding processing.
As a classic model of BMW, the BMW 7 series sedan uses the structural adhesive newly launched by the Dow Automotive Business Unit, which makes the adhesion between the metal body and the aluminum roof comparable. This two-component polyurethane adhesive called Betamate can facilitate the bonding of lightweight objects and complex assembly processes. In addition to the welding process cannot be used for the bonding of aluminum and steel structures, the effect of thermal expansion coefficient on the bonding effect must be fully considered when bonding with other methods. Dow has already thought about these aspects for customers. Betamate adhesives can eliminate the inconvenience caused by thermal expansion and contraction without affecting the stability of the bonded object.

"Hefty Consumer Products Vice President John N. Schwab said. "With this new HeftyUltraFlex large kitchen garbage bag, customers can directly get the benefits of odorless Block technology, and they also expect Hefty garbage bags. The excellent performance that can be brought. "Schwab added. Kitchen trash bags are often left in the trash can for several days and produce unpleasant odors. Using Hefty Odor Block technology, odor offset and neutralizers can be used to control the odor released in the trash can, thereby Make the air in the surrounding environment fresher.
