Convinced that people who understand this area are clear about the many major uses of nylon raw materials in many markets, and its type itself is divided into many kinds of diverse, such as nanotechnology nylon, extremely strong nylon, PA nylon, casting nylon, modified nylon, etc., there are a lot of types, and many people most likely are not very grasp, the following take a look at the PA6 Modified Plastic Nylon Performance What Improvement?
1, fiber reinforced
It applies the high abrasion resistance of the fiber to carry a large number of thermal stresses, with the help of PA6 sheet composite resin ductility circulation and its bonding with the fiber to transmit thermal stresses.PA6 fiber reinforcement using the material more generally is laminated glass fiber fiber, others are also carbon fibers, high purity graphite fibers, boron fibers, special fine metal material fibers, monocrystalline fibers and fibers and so on.
2, filling enhancement
PA6 modified filling enhancement of the use of powdered filler: carbon black, lightweight silica, calcium carbonate, calcium bicarbonate, active zinc oxide and so on. Powdered filler particles charisma surface layer has more prominent suction command PA6 polymer molecular chain of professional ability, with which caused the chain of physical thermal polymerization, to promote the external force, can be synergistically distributed load, improve the physical properties of the raw material, corresponding to the corresponding reduction of the raw material the chances of cracking. Filler particles and PA6 molecular chain at the interface of the amphiphilicity of the better, the greater the fusion, the more obvious enhancement will be.
Adding enhancement in the improvement of raw materials in the surface gloss, heat resistance, manufacturing characteristics, etc. has an unusual role, and fiber enhancement combined with the use of PA6 raw materials can effectively improve the hydroxyl aldehyde condensation characteristics, expanding its scope of application.
3,Liquid crystal enhancement
This method is the PA6 plastic and thermoplastic blending to produce extraordinary performance of composite materials, its enhancement of modified liquid crystal display polymer is generally thermotropic carbon chain liquid crystal display, in the blends can be caused by microfibers and have the role of enhancement. This type of modification method is more costly, the use of more different levels.
4, copolymerization modification, nano-enhanced and other methods
PA6 polymer modification and modification of blending modification method is similar, is in the epoxy resin adhesive aggregation, PA6 alone with PA66, polythiophene and other individual mixed in a certain ratio and common exciting aggregation, to get the PA6 three-block polymer or modified polymer taking into account the advantages of the two, the physical properties have been significantly improved.
PA6 nanomaterials enhancement of the prevailing forms are: insertion of mixed type method, blending method (including melt blending, solubility or moisturizing emulsion blending, industrial equipment blending, etc.), the starting point of aggregation or domination dispersion polymerization, colloidal solution - gel method, and so on.
