It is commonly known as Niron (Nylon), which is the general name of the polymer containing amido groups in the repeating unit of the main chain of macromolecules. Among the five major engineering plastics, the highest yield, the most variety and the most widely used are the varieties. The main varieties of nylon 6 and nylon 66 nylon, dominant, nylon 6 and nylon 66 nylon, poly two acyl 1,6-diaminohexane, nylon 66, nylon 6 is hard l2%; followed by nylon 11, nylon 12, nylon 610, nylon 612, nylon 1010 and nylon 46, and nylon 7, nylon 9, nylon 13, nylon 6I, new varieties of nylon 9T and nylon MXD6 (special barrier resins), nylon modified variety quantity, such as nylon, reinforced monomer casting nylon (MC nylon), reaction injection molding (RIM) nylon, nylon, nylon, aromatic high impact (super) nylon, nylon, nylon, electroplating conductive flame retardant nylon, nylon and other polymer blends and alloys, meet various special requirements, widely used in metal, wood and other traditional materials. Chinese name Nylon 66 Foreign language name Polyamide 66 Also known as Nylon 66 Abbreviation Nylon 66 CAS number 32131-17-2 Composition Poly two - hexamethylendiamine Scope of application Parts of mechanical, automobile, electrical equipment Catalog 1.1 application 2.2 injection mold conditions 3. after injection pressure 4. after the injection speed 5.3 production method 6.4 physical and chemical properties 1.5 physical property table 2.6 model 3. the United States after liquid nitrogen 4. after the United States DuPont 5. after Shenzhen DuPont 6. after Japan DuPont 1. after South Korea DuPont 2. after MITSUBISHI Engineering 3.7 introduction 4. after the performance After the 5. conditions 6. discipline characteristics After the 1. advantages 2. after use 3. after classification 4.8 detailed overview application PBT The hygroscopic property of PBT is very weak. The tensile strength of the non enhanced PBT is 50MPa, and the tensile strength of the glass additive type PBT is 170MPa. Too much glass additives will cause the material to become brittle. PBT; the crystallization is very rapid, which will cause the bending deformation due to the inhomogeneous cooling. For materials with glass additives, the shrinkage rate of flow direction can be reduced, but the shrinkage rate perpendicular to the process is basically the same as that of common materials. The shrinkage rate of the general material is between 1.5%~2.8%. The materials containing 30% glass additives shrink between 0.3%~1.6%. The melting point (225%C) and high temperature deformation temperature are lower than that of the PET material. The softening temperature of VEKA is about 170C. The glass transition temperature (glass trasitio temperature) is between 22C and 43C. Because the crystallization rate of PBT is very high, its viscosity is very low, and the period of the plastic parts is generally low. Synthetic process synthetic route 1. PBT intermittent type, Polytex Design, PTA route synthesis?or?DMT route synthesis (English: Batch-poly) 2. PBT continuous type, Polytex Design, PTA route synthesis. Batch method Process description 1. 1-4 butanediol mixing and conveying system 2. pre melting preparation system 3. esterification reaction system 4. polycondensation reaction system 5. slice cutting and packing system 6. catalyst preparation system 7. filter cleaning system 8. THF recovery system 9. heat medium system 10. computer integrated control system Characteristic The 1. slurry preparation system is used in the production of modified PBT, and the catalyst and additive can be added at low temperature. PC/ABS alloy, PC and ABS blends can combine the excellent properties of PC and ABS, improve the heat resistance, impact and tensile strength of ABS, reduce the cost and melt viscosity of PC, improve the processability, and reduce the sensitivity of product internal stress and impact strength to the thickness of products. The rapid development of PC/ABS alloy, the global output of about 800 thousand tons / year, the world's major companies have developed new varieties of PC/ABS alloy, such as flame retardant, glass fiber reinforced, electroplating, UV resistant varieties, especially widely used in the automotive industry, is also widely used in computers, copiers and electrical and electronic components. China has started a research and production of PC/ABS alloy materials such as Shanghai jieshijie company has been applied to Automobile decorative parts, lamp shell and heat appliance shell; Development Institute of the Chinese Academy of Applied Chemistry Changchun high heat resistance, high heat resistance and high impact resistance and high heat resistance of the three grade PC/ABS alloy material has been a number of domestic automobile manufacturing the company used for front decorative board, instrument panel and box cover and other special material goods. Lanzhou University study in PC/ABS blend with a high pressure polyethylene compatibilizer, the mixture obtained good flowability and low temperature toughness and modulus is almost not affected, for the production of sheet; domestic researchers in order to reduce the PC/ABS interface between two phases, adding impact agent MBS in PC and ABS, the degree of the impact of air alloy can achieve very high value, PC/ABS/MBS appearance is ivory white, uniform texture, feel good.
