Mc nylon

November 27, 2019

Mc nylon, also known as cast nylon, is preheated to a certain temperature in a mold in an oven, and then the chemically reacted solution is cast into the mold, which is polymerized to form a cast nylon blank. Beds are processed into finished products.
It is a high-tech product that has been vigorously promoted and applied in the world in recent years. It is a high-molecular polymer with a molecular weight of about 150,000. Its physical and chemical properties are better than other types of engineering plastics. It is an alternative to steel and copper. , Aluminum, Babbitt and other non-ferrous metals and polyurethane, PTFE, rubber, glass steel, plastic parts, ideal materials, has been widely used in various industries.

According to foreign research materials and testing and identification by China's authoritative departments, it has the following advantages:
1. Mass density is only 1/7 of steel, 1/8 of copper, 1 / 2.5 of aluminum alloy. Because of its light weight, when used as a mechanical material, it can reduce unnecessary strength and power of parts and components, and can reduce the inertia of movement.
Second, does not produce noise, the modulus of Mc nylon is much smaller than that of metal, and the attenuation rate of vibration is dozens of times greater than that of steel, and it has sound absorption function. When using Mc nylon to make gears and wheels, the noise is low, which is a more economical and practical way to prevent mechanical noise.
Third, good mechanical properties Mc nylon products have high mechanical strength, good toughness, impact resistance, fatigue resistance, especially with good creep resistance, so they can withstand heavy loads of the bearing for a long time; compression deformation (5%): 80- 120MPa; working temperature -50 ℃ ~ 180 ℃.
Fourth, Mc nylon products with good resilience can prevent the curved surface from undergoing permanent deformation, which can maintain the toughness to resist the breakage caused by repeated impact loads. This is an ideal material for articles used to withstand high impact loads.
Fifth, wear-resistant and self-lubricating Mc nylon products can be used without adding lubricant when it is used under general heavy load and low speed. Its wear characteristics are: friction coefficient is 0.3 ~ 0.4. In addition, Mc Nylon has a much lower hardness than metal, so it does not damage the friction parts. This is very useful for making rollers, bearings, bushings, bushes, wheels, car linings and other products.
Six, good chemical stability Mc nylon is colorless, non-toxic, low water absorption, resistant to strong acids, alkalis and various organic chemical solvents, oil resistance, anti-aging. The lubricant is not strictly required, and oil, water and grease can be used.
VII. Buried to foreign matter, excellent performance Mc nylon can work normally under the harsh conditions of the presence of abrasive impurities, and will not bite or hurt the shaft. This is ideal for mud pump piston rings, seal rings, bearing pads, bushings, etc. for drilling.
8. Non-adhesive nylon has the property of not rusting and not easily bonding with other materials. It can be used as a hoisting bucket, floor roller, pulley, idler, etc. of a coal mine conveyor.
Performance and Application of MC Nylon 1. Introduction to MC Nylon Application As one of engineering plastics, MC nylon products "replace steel with plastic and have excellent performance" have extremely wide applications. It has a variety of unique properties such as high weight strength, self-lubrication, wear resistance, corrosion resistance, and insulation. Its friction coefficient is 8.8 times lower than steel and 8.3 times lower than copper.
