Overview
_Polyethylene special-shaped parts are thermoplastic engineering plastics. It combines the superior properties of all plastics and has excellent properties such as wear resistance, impact resistance, chemical corrosion resistance, self-lubrication, resistance to low temperature wear coefficient, small weight, light absorption, aging resistance, flame retardant, antistatic and other excellent properties.

> Features
>Ultra-high molecular weight polyethylene plate ranks first among plastics in wear resistance, and the higher the molecular weight, the higher the wear resistance and impact resistance of the material
/> _ The impact strength of ultra-high molecular weight polyethylene board is the highest among existing plastics. Even at ℃, it still has a very high impact strength
Self-lubricating
Ultra-high molecular weight polyethylene board has extremely high water absorption rate Low. Therefore, its physical and mechanical properties have nothing to do with the humidity factor in the working conditions used
Ultra-high molecular weight polyethylene board is chemically stable and can withstand the corrosion of various corrosive media such as acids, alkalis, salts and organic solvents within a certain temperature and concentration range.
Ultra-high molecular weight polyethylene board is tasteless, non-toxic, odorless, non-corrosive, has physiological circulation and physiological adaptability
Non-adhesiveness
The embrittlement temperature of high-density polyethylene exceeds 10,000 hours down to ℃. Ultra-high molecular weight polyethylene can even be used at temperatures below ℃ under the action of liquid nitrogen and still has a certain mechanical strength.
>Application
>Gear and Worm Gear
_ The advantages of worm gear made of nylon are light weight, fatigue resistance, impact absorption and good self-lubricating performance. Nylon gears are most suitable for parts that are afraid of lubricant contamination or cannot add lubricant frequently. They do not damage the corresponding gears or online joints. They are low-noise and have significant effects in various industrial applications such as textiles, paper, printing, and food machinery. The noise is only that of steel parts. .
Slider
In heavy industry, nylon material is used as slider in metal rolling presses, forging machines and other industrial machinery. It has the following advantages: long service life, replacement time and maintenance costs can be greatly saved, and it can last for a long time after adding grease once. Maintain lubrication performance over time, resistance to impact, fatigue, vibration, high noise, low weight, easy assembly, and good wear resistance.
Piston ring support ring
The characteristics of using nylon as a piston ring are that it is light in weight and weighs about 100% of bronze. It reduces motion losses and saves mechanical power. It has good sliding performance and has a small difference in static and dynamic friction coefficients, so it does not have viscosity like metal. Good physical properties can prevent the cylinder liner from being frayed, oil-free, self-lubricating, good sealing, not prone to oil leakage, long service life, and improved work efficiency.
Shaft sleeve bearing bearing
Using nylon as a shaft fitting has the following advantages: good wear resistance, good self-lubricating performance, and a high value among general thermoplastics. Small friction coefficient, impact resistance, not easy to hold the shaft and sintered, does not damage the journal, long lubrication cycle to reduce maintenance, strong adaptability and long life in harsh environments.
Roller roller
Because nylon has chemical-resistant, wear-resistant and self-lubricating properties, it is used to make rollers or as outer bushings of metal rollers for conveying guide rollers, reverse rollers, and wandering rollers. suitable. Nylon has a longer service life than other materials, is easy to process and requires less refueling, and does not leak or rust. Oil and rust stains will not contaminate the fiber.
Other aspects
In addition to the above introduction, nylon is widely used in many aspects, such as mixer supporting wheels, valve bodies, valve cores, gaskets, insulation sleeves, guide plates, pulleys, etc. In railways, there are moving axle box linings, moving wheel springs, lifting sets, retaining rings Cross-head sliding shoes, rocker small ends, small square tiles, etc. In the shipbuilding industry, there are bearings, water pumps, bearings, pulleys, sliders, sprockets, handles, anti-electric seals, etc.
