Jiangmen engineering plastics analysis on the application of Polyamide Engineering Plastics in which fields
Polyamide has been well used in many fields of national production, such as car manufacturing, mechanical equipment production, electronic and electrical work, chemical equipment production and so on.
(1) application of polyamide in car manufacturing due to the requirements of car lightweight and reduced cost in recent years, engineering plastics are more and more widely used in car manufacturing. Automotive parts are required to be resistant to high and low temperature, oil, chemicals and weather, while polyamide can meet the above functional requirements, so it is widely used. Polyamide is mainly used as the following parts in the car manufacturing industry.
The radiator is a large product made of glass fiber reinforced polyamide. The weight of the product can be greatly reduced by replacing the original metal materials with polyamide.
The belt pulley is made of glass fiber reinforced polyamide with graphite. After replacing the original cast iron, the weight and working hours can be reduced.
The adsorption tank made of polyamide has good oil resistance, heat resistance and vibration resistance.
The oil pump gear made of PA66 has good reliability and can be used as a structural part in car manufacturing.
(2) application of polyamide in mechanical equipment production
Because of a series of excellent functions, such as toughness, wear resistance, self lubrication, high rigidity, heat resistance, etc., it is widely used to manufacture mechanical parts, such as gears, turbines, seals, bearings, etc.
General machinery manufacturing polyamide can replace metal materials to manufacture various types of mechanical parts. Its advantages lie in improving wear resistance, increasing longevity, reducing cost and reducing weight.
Bearing polyamide, as bearing material, is widely used in car, ship, metallurgy, textile, papermaking and other fields. Polyamide bearings reduce the weight of products and have good wear resistance and reliability. They replace the traditional process together and greatly save man hours.
The polyamide gear for gear injection or casting not only has the advantages of simple production process and equipment, reliable function and wear resistance, but also can reduce the technical requirements of manufacturing and device due to the elastic function of polyamide gear to compensate processing and device errors.
(3) application of polyamide in electronic and electrical equipment. Polyamide has good electrical function and can be widely used in the manufacture of general electronic and electrical components.
Coil winder PA6, PA66, etc. are used to manufacture coil winders. Because the products require high strength and high rigidity, glass fiber reinforced polyamide is often used. Together, the products are required to have good flame retardant function.
The terminals are mostly reinforced PA6 and PA66. The products shall have good heat resistance, electrical insulation and flame retardancy.
TV tuning elements are generally made of flame retardant PA66. It is required to be used at 105 ° C for a long time, and the flame retardant function shall reach UL-94V-0.
High voltage safety switch is made of homonymous copolyamide. It has excellent electrical function, mechanical function and light transmittance.
(4) application of polyamide in chemical equipment polyamide has good corrosion resistance, oil resistance and aging resistance, so it is widely used in the manufacture of chemical equipment, such as pipes, filters, containers, etc. the products have the advantages of good corrosion resistance, oil resistance, cost reduction and weight reduction.
