The application effect and social and economic benefits of nylon powder are remarkable

2022/04/13

Nylon powder is widely used, and its application effect and social and economic benefits are particularly significant.

Comprehensive application of nylon powder

Nylon powder is used as vibration-absorbing and wear-resistant material to replace non-ferrous metal and alloy steel, 400 kg MC nylon product, its actual volume is equivalent to 2.7 tons of steel or 3 tons of bronze, the use of MC nylon parts unfairly improves mechanical efficiency and reduces maintenance, Generally extend the service life two to three times.

(1) Gears and worm gears

The advantages of nylon powder as gears and worm gears are light weight, fatigue resistance, shock absorption, and good self-lubricating performance. For parts that are afraid of lubricating oil pollution or cannot be lubricated frequently, MC nylon gears are most suitable, and do not hurt the corresponding gears or online accessories. Noise Low, the effect is remarkable in textile, papermaking, printing, food machinery and other industrial applications, and the noise is only 1/4-1/2 of that of steel parts.

(2) Slider

 

 

MC nylon material is used as a slider in industrial machinery such as heavy industrial metal wire drawing machines, forging presses, etc. It has the following advantages: long service life, greatly saving replacement time and maintenance costs, long-term lubrication performance after one-time addition of grease, impact fatigue resistance and Strong vibration ability, low noise, light weight, easy assembly and good wear resistance.

(3) Piston ring and support ring

The piston ring made of nylon powder has the following characteristics: light weight: about 15% of the weight of bronze, reducing motion loss, saving mechanical power, good sliding performance, small difference in static and dynamic friction coefficient, not sticky like metal, Good physical properties, can avoid cylinder liner pulling, oil-free self-lubrication, good sealing performance, not easy to leak oil, long service life, and improve work efficiency.

(4) Bushings, bushes and bearings

The use of nylon powder as shaft accessories has the following advantages: good wear resistance and self-lubricating properties, high PV value among the currently common thermoplastics, small friction coefficient, impact resistance, not easy to hold the shaft, sintering, no damage Journal, long lubrication cycle, reduced maintenance, strong adaptability to harsh environments, and long service life.

(5) Rollers and rollers

Because nylon powder has chemical resistance, wear resistance and self-lubricating properties, it is suitable for use as the outer lining of rollers or metal rollers for conveying guide rollers, reversing rollers and walking rollers. Compared with other materials, MC has a longer service life and can be processed Easier, less oiling, no oil leakage, no rust, no oil stains, no rust spots.

(6) Other aspects

In addition to the above introduction, nylon powder is also widely used in many aspects, such as: internal mixer supporting roller, valve body, valve core gasket, insulating sleeve, guide plate, pulley, etc., there are moving axle box bushings on railways, moving wheel springs are withdrawn In the shipbuilding industry, there are bearings, water pump bearings, pulley blocks, sprockets, handle anti-electricity and seals, etc.
