Food machinery wear parts

Overview of polyethylene shaped thermoplastic engineering plastics. It combines all the advantages of plastic can, resistant to abrasion, impact resistance, chemical resistance, self-lubricating, low temperature resistance wear coefficient is small, light weight, energy absorption, anti-aging, flame retardant, antistatic and other fine performance. Category UHMWPE shaped pieces, polyethylene sleeve, food machinery rail, wash tank vacuum box panel, polymer food machinery slider UHMW wear strips, shaped slider, polyethylene baffle blocks, polyethylene bridge guard rail pad features 1, ultra high molecular weight polyethylene plate wear resistance ranks first in plastic, and the higher the molecular weight, wear resistance and impact resistance, the higher material; 2, ultra high molecular weight polyethylene plate impact strength is the highest value of existing plastics, even at 70 ℃ still has a very high impact strength; 3, self-lubricating; 4, ultra-high molecular weight polyethylene plate low water absorption. Therefore, the physical and mechanical properties and working conditions of humidity factors unrelated; 5, ultra high molecular weight polyethylene sheet is chemically stable, at a certain temperature, concentration range to acid, a variety of corrosive media and alkali, salt and other Corrosion organic solvents; 6, ultra high molecular weight polyethylene plate tasteless, non-toxic, odorless, non-corrosive in itself, with physical and physiological adaptation cycle 7, non-sticking; 8, molecular weight high density polyethylene over 500,000, the brittle temperature dropped to 140 ℃. UHMWPE even at liquid nitrogen effect, its temperature up to 269 or less ℃, still has a certain mechanical strength. Applications (1) gears, worm gears as MC nylon, advantages worm is light weight, corrosion fatigue, absorb shock, good self-lubricating properties. For fear of contamination or lubricant not always add lubricant site, with MC Nylon most suitable gear, and not to hurt or online correspond gear fittings, low noise, the effect in the textile, paper, printing, food machinery and other industrial applications significant noise is only 1 / 4-1 / 2 steel member. (2) the extension of the slider heavy metal presses, forging machines and other industrial machinery with MC nylon material for the slider, the following advantages, long service life, take for time and maintenance costs can save a lot, you can add oil after the first a long time to maintain lubrication properties, resistance to impact fatigue, resistance to vibration, noise, light weight, easy to assemble, good wear resistance. (3) piston rings, support ring made with MC nylon piston ring features: light weight: about 15% by weight of bronze, lowered sports wear and tear, mechanical power saving, good sliding properties, static and dynamic friction coefficient difference is small, it will not be like As metal sticky phenomenon, different physical performance, to avoid scuffing cylinder liner, oil-free self-lubricating, sealing, and not oil spills, long life, improve work efficiency. (4) bushings, bearings, bearings for shaft fitting MC Nylon has the following advantages: wear resistance, self-lubricating properties, with higher values ??in general PV thermoplastics. Low coefficient of friction, impact resistance, easy axle, sintering, not to hurt the journal, long lubrication cycle, reduce maintenance, harsh environmental adaptability, long life. (5) wheel roller, roller resistant to drugs due MC nylon, wear-resistant and self-lubricating properties, used for roller or a metal roller bush outer guide rollers for conveying, reverse roll, roll swimming They are suitable. MC Nylon long service life than other materials, easily processed, less the number of refueling, without leakage, no rust, grease and rust stains without staining fibers. (6) In addition to other aspects of the introduction, MC nylon far used in many aspects, such as: mixers roller, valve, valve gaskets, insulation jacket, guide plates, wheels, etc., there is movement in railway axle box liner, driving wheel spring revoke sets, stalls circle, crosshead shoe, rocker small end of the small square tile, etc., have in the shipbuilding industry in the bearings, water pump bearings, pulleys slider, wheel, handle anti-power, seals and so on.
