Active calcium carbonate (also known as modified calcium carbonate) is made of ordinary calcium carbonate powder (heavy calcium and light calcium) as the base material, and the surface of inorganic powder is modified and activated by using multi-functional surfactants and compound high-efficiency processing AIDS. The modified calcium carbonate powder forms a special coating structure on its surface, which can significantly improve the dispersibility and affinity in polymer matrix such as polyolefin, and can produce interface interaction with polymer matrix, so as to improve the impact strength of the product. It is a kind of incremental filler with excellent performance.

The cable sheath is the outermost layer of the cable, acting as the most important barrier in the cable to protect the internal structural safety, protecting the cable from mechanical damage during and after installation. Cable sheathing is not meant to replace the reinforced guard inside the cable, but they can provide a fairly high level of limited means of protection. In addition, the cable jacket provides protection against moisture, chemicals, UV and ozone.

In 1912, it was found that carbon black has a reinforcing effect on rubber, and since then carbon black has gradually become an indispensable raw material for the rubber industry.

Chlorinated rubber paint is suitable for anticorrosion of steel structures, oil tanks, gas tanks, pipelines, chemical equipment and plant steel structures. Of course, the concrete surface of some pool walls can also be used, but some often contact with benzene environment can not use chlorinated rubber paint.

 Chloroprene Rubber/Neoprene rubber is very widely used, mainly used as wire and cable sheath, rubber hose, oil-resistant rubber products, heat-resistant conveyor belt, printing rubber stick, rubber dam, construction seal, highway sealant, bridge support, waterproof cap for oil field wire, flame retardant rubber products, various sealing rings and chemical equipment anti-corrosion lining and neoprene adhesive. In recent years, neoprene rubber has been developed for new uses in building waterproof materials, sealing materials, adhesives, Marine development, medical and health care, energy development and people's life, and has expanded the application field.

In aquaculture, anhydrous magnesium chloride and magnesium chloride hexahydrate have their own applications. In general, if you need to quickly adjust the water quality, you can choose magnesium chloride hexahydrate; If you need long-term stable water quality, you can choose anhydrous magnesium chloride.

Recycled plastics have become an effective social resource, and recycled plastic components are often blended by two or more different materials, which can be used to produce a variety of plastic products. Modification of plastics is another simple and effective method to obtain new properties of resins besides polymerization.

The modified synthetic material is not only simple in process, low in cost, but also has excellent performance, thus expanding the application field of synthetic resin. The blending modification technology is a scientific and practical new technology to achieve high performance, multi-function and refinement of recycled plastics.

ABS plastics and MBS plastics are effective impact modifiers of PVC, the main difference is that the former is mainly used for extruding pipes, profiles and calending and blow molding bottles, it should be noted that such modified polymers due to the composition of butadiene unsaturated double bond structure, so mixed with PVC weather resistance is poor, in the formula should be added light stabilizer. Both are very toxic and can be used in contact with food.
