B: excellent tensile strength, good insulation performance. C: flame retardant, electroplating, heat-resistant and heat-resistant. D: high stiffness retention performance and good high temperature creep resistance. E: the stiffness and modulus of creep are PPS, PEI and PES of the same glass enhancement degree. F: it can be used for thin-walled parts with 0.1 millimeter parts without flfei. E:PA46 plastic is a multipurpose, glass - reinforced, flame retardant UL - class material that meets the requirements of UL VO. Injection molding process 1. dry sealed paper bags: no need to be dried in advance. The open paper bag must be placed in a dry material bucket with a dehumidifier and drying at a temperature of 4 hours at 120 degrees centigrade. The length of the drying is to the extent that the plastic is exposed to moist air. During the operation, the plastic must be placed in a dry material bucket with a dehumidifier, and the temperature is kept at 100. 2. injection temperature regulates melting temperature at 295. The ideal material temperature can be at 300~315 degrees centigrade. (it includes the tensile value of the material and the impact resistance value IZOD under the cantilever beam). After PA46 (transmission) middle (compression) anterior (measurement) nozzle without fiber reinforcement 285~300290 ~ 305295~310295 ~ 310 (material temperature) containing 285~305295 ~ 310300~315300 ~ 315 fiber reinforced plastic (material temperature) found free overflow at the furnace mouth, must take the temperature of the furnace mouth drop (of course also need to beware of plastic cooling in furnace in the mouth). In addition, the nozzle must be pressed with the template, but if the pressure is overpressed, the pressure can also be reduced. The 3. retention time is to prevent serious plastic performance decline during the operation. (mechanical properties in order to make the ideal residence time) is as follows: the highest free fiber reinforced PA46:6 fiber reinforcement containing ~ 10 minutes PA46:5 minutes to avoid the use of large capacity injection molding machine, opposed to product volume. Retention time = cycle time * (capacity / finished capacity of the furnace barrel for full load) 4. mold temperature suggests that the mold temperature is used at 80~140. Application of electrical and electronic applications: SMD components, connectors, circuit breakers, winding element, electric motor parts and electrical components; airborne components application: automotive applications cover gears, bearings and bearing: sensors and connectors, such as motor control system and air equipment, cable fasteners, hand Physical property table TPEEPreparation of nylon 66 salt Nylon 66 salt are prepared respectively the temperature ethanol ethanol solution with adipic acid hexanediamine at 60 DEG C above the mixing and salt precipitation, filtering, alcohol washing, drying, and finally preparing aqueous solution of 63%, use for polycondensation. The reaction formula is as follows: polycondensation The polycondensation of nylon 66 salt should be carried out at high temperature, with the removal of water, resulting in the formation of linear high molecular weight nylon 66. The reaction formula is as follows: The production process is divided into two kinds: intermittent method and continuous method. Continuous method is suitable for large-scale production, and the production of nylon 66 in the world mainly adopts continuous method. The batch method is used only in two cases: one is to produce special or experimental grade; two is in a small device with a production capacity of 4 500t A.。 Physical property table Supply region Europe Performance characteristics can be machinability, good Good chemical resistance Processing method injection molding Test method of physical performance rating unit system The density of 1.08 to 1.16 g/cm fand ISO 1183; Melt flow rate (275 C/1.2 kg) 40 to 60 g/10 min ISO 1133 Test method of physical performance rating unit system The proportion of 1.13 g/cm ASTM D792 fand; Shrinkage - flow 2.8% ASTM D955 Test method of mechanical performance rating unit system Tensile strength 75 MPa ASTM D638 Model Liquid nitrogen in the United States RF-7007, RL4540 Dupont 101F, 101F-NC010, 101L, 101L-BKB009, 101L-NC010, 1032L, 103F NC010, 103FHS, 103HSL, 10B, 10B40, Three thousand four hundred and twenty-six 408HS, 450HSL NC010, 45SHB NC, 490, 408L, 450 54G15HSLR BK031, 5514 70G13HS1-L, 70G13HS1L NC010, 70G13L 70G13SH1L, BK, 70G20HSL, 70G25HSL, 70G25HSLR-BK099, 70G30HSLR, 70G33HS1-L, 70G33HS1L-NC010, 70G33HSIL (BK), 70G33HSIL (NC), 70G33L, 70G35HSL, 70G35HSL NC, 70G43L, 70G43L-NC010, 71G13L, 72G13HS1L, 72G33W, 72G33HS1L, 72G33L BK031, 72G25V0 NC010, 73G25HSL BK260, 74G33J 74G33EHSL, BK354 77G33L-NC, 77G43L-BK031, 74G43J-NC010, 79G13HSL-NC, NC010, 7304 8018, 8018HS, 8061, 80G14AHS-BK099, 80G33HSL-NC010 NC010, ST811HS, ST901HSIL, ZYTA197 DuPont, Shenzhen FR50-NC010, HTN-FR52G30LX-BK337 DuPont of Japan 70G33HS1L BK031 DuPont of Korea 70G33L Mitsubishi Engineering-Plastics Corporation 3010SR, 3010CF30, 3010GN15, 3010N, 3021G-30, 3021GH-20, E2000W40 BK and so on.
