New reinforcement materials such as inorganic whisker reinforcement and carbon fiber reinforcement will become important varieties, mainly used for automobile engine parts, machinery parts and aerospace equipment components.
<:rr, , ②Nylon alloying will become the mainstream in the development of modified engineering plastics. Nylon alloying is an important way to achieve high performance of nylon, and it is also the main means to manufacture special nylon materials and improve the performance of nylon. By blending other polymers, the water absorption of nylon can be improved, the dimensional stability of the product, as well as low-temperature brittleness, heat resistance and wear resistance can be improved. Therefore, it can be used for different vehicle types.
<:rr, , ③The manufacturing technology and application of nano-nylon will develop rapidly. The advantage of nano-nylon is that its thermal properties, mechanical properties, flame retardancy and barrier properties are higher than those of pure nylon, while its manufacturing cost is equivalent to that of back-through nylon. Therefore, it is very competitive.

<:rr, , ⑥The research and application of processing aids will promote the process of functionalization and high performance of modified nylon. This product has a wide range of uses. It is a good material for plastic replacement of steel, iron, copper and other metals. It is an important engineering plastic. Cast nylon can widely replace the wear-resistant parts of mechanical equipment, replacing copper and alloys as wear-resistant parts of equipment. Suitable for making wear-resistant parts, transmission structural parts, household appliance parts, automobile manufacturing parts, screw rod prevention mechanical parts, chemical machinery parts, and 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, sleeve connectors, etc.

: >What properties does a nylon board have that can be considered to be of good quality? Hongbao will explain it to you.
<:rr, , The appearance of nylon is milky white to light yellow, with uniform particles that do not contain mechanical impurities and surface moisture. The particle size is larger than 1/gram and the number of particles with tiny black spots is not larger than 1. It is characterized by toughness, earthquake resistance, and It has high mechanical strength and heat resistance, good impact strength, high melting point, good molding and processing performance, high water absorption, saturated water absorption rate of about 10%, and is easily soluble in sulfuric acid phenols or formic acid. The low-temperature embrittlement temperature is Subzero degrees.
<:rr, , Nylon plate is transparent: it has good tensile strength, impact strength, rigidity, wear resistance, chemical resistance, surface hardness and other properties, high light transmittance, similar to optical glass, processing The temperature is ℃. During molding and processing, the barrel temperature needs to be strictly controlled. If the melt temperature is too high, it will cause discoloration of the product due to degradation. If the temperature is too low, the transparency of the product will be affected due to poor plasticization. The mold temperature should be as low as possible. High mold temperature will reduce the transparency of the product due to crystallization.
