MC nylon products (Monomer castingnylon) that cast nylon, is widely used engineering plastics, almost throughout all industrial sectors. Cast nylon using anionic polymerization techniques, the melt will be added with the catalyst the caprolactam monomer cast under atmospheric pressure in a mold of various shapes formed by the reaction of the casting products. MC nylon, a molecular weight of up to 7-10 million, generally nylon (such as nylon 6, nylon 66) 3 times, and thus its overall mechanical properties than other nylon materials better. It has the following five characteristics:?????? Shaped pieces of high molecular weight polyethylene UHMWPE polymer polyethylene shaped pieces of UHMWPE outstanding abrasion resistance: the coefficient of friction is usually 0.1 to 0.3, approximately 1/4 of Bakelite babbitt 1/3, so it is a self-lubricating material. ??? High molecular weight polyethylene UHMWPE polymer shaped pieces of polyethylene shaped pieces of UHMWPE good mechanical properties: surface hardness, and is highly resistant to tensile flexural strength and impact strength and high ductility: compressive strength and the metal is not down, the fatigue strength and the same level of the metal material such as cast iron and aluminum alloys. ??? Shaped pieces of high molecular weight polyethylene UHMWPE polymer polyethylene shaped pieces of UHMWPE excellent chemical stability: both weak bases, alcohols, esters, copper, hydrocarbon oil ester chemicals are unaffected. ??? Shaped pieces of high molecular weight polyethylene UHMWPE polymer polyethylene shaped pieces of the UHMWPE hardy heat resistance: -60 ° C case to maintain a certain degree of mechanical strength, heat resistance temperature of 80-100 ° C. ???? Of UHMWPE polymer of high molecular polyethylene shaped pieces polyethylene shaped pieces of UHMWPE proportion of light: the proportion of it in between 1.05-1.15. ? General application (1) gear, worm gear??? MC nylon for gear, the advantages of the worm gear is light weight, resistance to fatigue, absorb shock, good self-lubricating properties. For fear of lubricant contamination or plus parts of lubricants frequently the most suitable MC nylon gear, corresponding gear online to pieces, not to hurt the noise effect in the textile, paper, printing, food, machinery and other industrial applications significantly, only steel parts 1/4-1/2 noise. (2) the slider??? Heavy industry of metal extending the press, forging machine, and other industrial machinery using MC nylon slider in the following advantages, long service life, taken-for-time and maintenance costs can save a lot of time plus grease after a long period of time to maintain lubrication performance impact fatigue resistance, shock resistance, noise, light weight, easy assembly, good wear resistance. (3) piston rings, support rings??? With the MC nylon piston ring characteristics: light weight: 15% of the weight of the bronze reduce sports Loss, mechanical power savings, good sliding properties, static and kinetic friction coefficient difference between small, so not like metal viscous phenomena of different physical properties, can avoid Liner nap, oil-free, self-lubricating, sealing is not easy to spill, long service life, improve work efficiency. (4) bushings, bearings, bearing??? MC nylon shaft fittings has the following advantages: wear resistance, self-lubricating properties and high PV value in the current general thermoplastics. Small coefficient of friction, impact-resistant, not easy to hold the shaft, sintered, not to hurt the journal lubrication cycle is long, reduce maintenance and adaptability in harsh environments, long life. (5) wheel roller, roller??? The MC nylon having a resistance to drugs, such as wear-resistant and self-lubricating properties, is used to do the roller or as the outer layer of the metal roller liner for a transfer guide roller, a reverse roller, swimming rollers are suitable. Easily of MC nylon long service life than other materials, processing, fewer refueling, and no oil spills, no rust, oil, and rust stains will not stain the fiber. (6) other??? Addition to the above description, MC nylon far used in many aspects, such as: a stirrer supporting wheel, the valve body, the spool washer, insulating jacket, guide plates, pulleys etc., in railway Activity axlebox liner, drive wheels spring revoke sets stalls circle, crosshead slipper rocker Xiaoduan small square tiles in the shipbuilding industry, bearings, water pump bearings, pulleys, sliders, sprocket, handle anti-power, seals, etc. .
