MC nylon claims again nylon monomer-cast nylon, it is under normal pressure, the raw material caprolactam monomer C6H11NO of melting is made catalyzer with the material of alkalescence, make with auxiliary agents such as activators and to treat poly-monomer, directly inject the mould that is preheating to certain temperature, make material in mould, carry out soon polyreaction, condense into tough and tensile solid embryo spare, process again the goods that obtain being scheduled to through relevant technological.The MC nylon products is as one of engineering plastics, " with mould Dai Gang, performance is remarkable ", purposes is extremely extensive.It has lightweight, intensity is high, self-lubricating, wear-resisting, anticorrosion, the multiple special performances such as insulation are widely used engineering plastics, almost spread all over all industrial circles.The character of MC nylon:
(1) high strength can be born load for a long time;
(2) good rebound resilience can be crooked and indeformable, can keep toughness simultaneously, the opposing repeated stock;
(3) wear-resistant self-lubricating provides to be better than bronze cast iron carbon steel and the serviceability of phenolic laminate without oil (or de-oiling) lubrication applications the time, reduces consuming save energy;
(4) inhale noise, damping, MC nylon modular ratio metal is much smaller, and is large to the decay of vibrations, provides to be better than the practical approach that metal prevents noise;
(5) with the metallographic phase ratio, MC nylon hardness is low, does not damage the mill part;
(6) low mc coefficient, it is provided, and widespread use may on friction member;
(7) high chemical stability, alkaline-resisting, pure, ether, hydrocarbon polymer, weak acid, lubricating oil, washing composition, water (seawater), and have odorless, nontoxic, tasteless, rustless characteristics, for it is widely used in the alkali resistant corrosion, the component of machine of the aspects such as environmentally-friendly sanitary, food, textile printing and dyeing is provided by the good condition that provides;
(8) maintenance, the labor savings of simplification machine, good mechanical cutting processing characteristics, raising productivity.
1. application and the forming machine range of application of China MC nylon are very little at present, only limit to coil class and excellent class etc.By modification, the different auxiliary agent of interpolation, tighten and improve nylon chemical ratios and composition, can make mechanical characteristics and require different engineering plastics products, cost is less than steel in addition, and the adaptation field also can enlarge.
2. the nylon guide deflection sheave of modified MC nylon guide deflection sheave performance and prior art has the raising of matter: intensity improves, and bearing load has in the past 35 tons to bring up to more than 60 tons: tensile strength has 40-60MP to bring up to 60-90MP; Ball indentation hardness has 60-100N/mm2 to bring up to 120-160N/mm2; Heat-drawn wire has 90-150 ° of C to bring up to 180-210 ° of C; Other performance also improves a lot.Anti-fatigue, anti-oxidant, anti-ultraviolet performance have also been improved in addition.
3. the preparation of modified MC nylon guide deflection sheave has one of matter to be both the centrifugal forming liquid filling machine with the major equipment of the present MC nylon molding of China, all is manual forming machine.Artificial matched moulds, casting, moulding, divide mould, labour intensity is high, and efficient is low, if the guide deflection sheave of moulding 8kg, about 30 minutes of shaping cycle, a working days, (8 hours) moulding product was 16, efficient is very low, forming machine is without gas barrier at present in addition, and the aerosol that moulding produces freely distributes aloft, production plant, very unfavorable to workman's health.Contrast is external, MC nylon automated production equipment is also arranged, but price is very expensive, and cost performance is lower, the enterprise of the project on new to major part, and it is larger to bear financial pressure, thereby has limited the application and development of MC nylon product.And the preparation of modified MC nylon guide deflection sheave realizes automatization control greatly reducing labour intensity; Production efficiency has improved 2.5 times, and a working days of separate unit machine, (8 hours) moulding product was 40; Yield rate has 96% to bring up to 99.8%, has reduced cost, and product performance are more stable.
Modification post-modification MC nylon guide deflection sheave performance preparation method has qualitative leap, has filled up domestic blank, with promoting China MC nylon to mould the paces of Dai Gang, accelerates the popularization and application of novel material, and save energy is country and the larger value of social creativity.
