Nylon rods what are the purposes

by:MPS     2020-10-05

nylon rods with good toughness, abrasion resistance, oil resistance, strong anti-seismic, good tensile, bending strength, and has the characteristics of small water absorption, good dimensional stability, and is used for processing various wear-resistant high strength parts.

nylon rods, widely used in plastic instead of steel, iron, copper and other metal material, is an important engineering plastics; Cast nylon instead of mechanical equipment wear parts, instead of the copper and alloys for equipment wear resistance. Is suitable for making wear parts, transmission parts, home appliance parts, automotive parts, wire rod to prevent the machine parts, chemical machinery parts, chemical equipment. Such as turbine, gear, bearing, impeller, shaft, dashboard, drive shaft, valve, blades, wire rod, high pressure washers, screws, nuts, seals, shuttle, set of Jane, axle housing connector, etc.

quality difference:

1, nylon appearance of milky white to light yellow, not including mechanical impurities and surface moisture uniform particle, particle size greater than 40 grain/g granules contain no greater than 2%, with small black spots is characterized by ductile, seismic, has high mechanical strength and heat resistance, impact strength, high melting point, good processing performance, large water imbibition, saturated water absorption rate at about 11%, fusible in sulfuric acid phenol or formic acid, low temperature embrittlement temperature is 20 degrees below zero - 30 degrees.

2, nylon rods transparent PA: good tensile strength, impact strength, rigidity, abrasion resistance, chemical resistance, surface hardness, such as performance, high light transmittance, similar to optical glass, processing temperature is 300 - - - - - - - 315 ℃, molding processing, the need to strictly control the barrel temperature, melt temperature is too high will be caused by the degradation products, the low temperature will be because of the transparency of adverse effects and plasticizing products. Mold temperature to get lower, high mold temperature will reduce the transparency of products by crystallization.
