Widely used, it is a good material for plastic, steel, iron, copper and other metals. It is an important engineering plastic; cast nylon widely replaces the wear parts of mechanical equipment, replacing copper and alloy as wear-resistant parts of equipment. Suitable for making wear parts, transmission structural parts, household appliance parts, automobile manufacturing parts, screw rods to prevent mechanical parts, chemical machinery parts, chemical equipment. Such as turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, blades, screw rods, high pressure washers, screws, nuts, seals, shuttles, sleeves, bushing connectors, etc.
Quality identification:
What are the properties of the nylon board that can be considered good quality? Henan Hangfa explained for you one or two. The appearance of nylon is milky white to light yellow, uniform particles containing no mechanical impurities and surface moisture, and the particle size is more than 40 grains/g. The number of particles containing fine black spots is not more than 2%. It is characterized by toughness, earthquake resistance, high mechanical strength and Heat resistance, good impact strength, high melting point, good molding processability, high water absorption, saturated water absorption rate of about 11%, easy to melt in sulfuric acid phenols or formic acid, low temperature embrittlement temperature is minus 20 degrees - 30 degrees.
Nylon plate transparent PA:
Has good tensile strength, impact strength, rigidity, wear resistance, chemical resistance, surface hardness and other properties, high light transmittance, similar to optical glass, processing temperature is 300--315 ¡ãC, when molding, need Strict control of the barrel temperature, too high melt temperature will cause discoloration of the product due to degradation, too low temperature will affect the transparency of the product due to poor plasticization. The mold temperature should be as low as possible, and the high mold temperature will reduce the transparency of the product due to crystallization.
