Grass brick mold plastic polypropylene PP pp raw material is prepared by a thermoplastic resin polymerization of propylene, is a semi-crystalline materials 25x19x8 lawn brick mold, it is harder than PE and has a higher melting point. Polypropylene (pp) has good plasticity, soluble and toughness. Made of ABS resin, ABS resin is a slightly yellow solid, have a certain toughness, it is acid, alkali, salt corrosion strong 25x25x6 lawn brick mold, also dissolved in an organic solvent can be tolerated to some extent. ABS resin good formability, processed products smooth surface, easy to dyeing and electroplating. The advantages of ABS resin is abrasion resistance, noise resistance, scratch resistance, heat resistance and better. Of course, whether it is using pp raw materials, or ABS resin material, the molding process is similar, ie the particles into a liquid under high temperature, the liquid into a particular good iron plastic mold, the use of liquid water circulation to cool, according to the plastic on plastic mold specifications and plastic. Performance ① density: small plastic density, reduce the mechanical equipment for the weight and energy saving is significant, especially for vehicles, ships, aircraft, spacecraft cosmic terms. ② specific strength and specific stiffness: Definitely not as good as metal high-strength plastic, but the small plastic density, so specific strength (σb / ρ), considerably higher than the stiffness (E / ρ). Especially in a variety of high-strength plastic reinforced fibrous, flake and powdered filler metal or metalloid is made further higher specific strength and specific rigidity than metal. ③ chemical stability: The vast majority of plastics have good acid and alkali, performance lawn brick mold salt, water and gas, under normal conditions, they do not interact with these chemical reactions. ④ Insulation resistance: good electrical insulation, insulation, absolutely sound performance. ⑤ wear-resistant and self-lubricating: small plastic friction coefficient, good wear resistance, good self-lubricating five-hole lawn brick mold, with high strength, low noise transmission, it can be in a liquid medium, semi dry even under dry friction conditions effectively. It can be made of bearings, gears, cams and pulleys and other machine parts, speed is not very suitable for high load is not the occasion. ⑥ bonding capability: the state can be a good bonding analysis done no less. ⑦ good shape and color performance: very regular shape, color is also very well-proportioned without the slightest deviation.
