Shanghai Daoqin Plastics Co., Ltd.

PA1010（ nylon 1010） plastics raw materials is in 1958 year made, 1959 year Shanghai 赛璐珞厂 most start production. production technology 路线　　PA1010（ nylon 1010） plastics raw materials is 由癸二 acid polycondensation made. will acid and amine and other ratio solvent alcohol in, in pressure 75℃ lower in and reaction, formed nylon 1010 salt. nylon 1010 salt in, in 240-260℃, 1.2-2.5Mpa lower polycondensation made nylon 1010. polycondensation can separation method and method. can use made amine and acid and other ratio water solvent liquid polycondensation made polymer, rear belt/tape, cooling, pelletizing made nylon 1010粒 material. PA1010（ nylon 1010） plastics raw materials molding process 　　PA1010 plastics raw materials relatively narrow, generally is 3～4℃. melt flow property relatively good. combined injection molding, extrusion molding and blow molding. main/primary molding process lower. 　　(1) drying 　鼓风 drying temperature degree 90℃±5℃ drying time 约4～5h, true drying temperature degree 85℃±5℃, generally most good selection true drying process, hot oxidation color 　　(2) injection molding process 　　 material temperature degree: rear 部190～210℃ 　　 in 部200～220℃ 　　 front 部210～230℃ 　　 nozzle 200～210℃ 　　 mold temperature degree 20～40℃ 　　 injection pressure 60～80MPa 　　 injection cycle 30～50S, 　　(3) extrusion molding process 　　 screw extrusion temperature degree: 250℃, 260℃, 270℃, 280℃ 　　模头 temperature degree:200～210℃PA1010（ nylon 1010） plastics raw materials property can 　　PA1010（ nylon 1010） plastics is semi transparent, light hard, surface light crystallization white or micro color pellets, versus for density and water property ratio nylon 6 and nylon 66 low, machine strong/high degree high, impact tough property, wear resistance and lubricated property good, resistant property ratio nylon 6 good, melt flow property good, easy molding processing, melt temperature degree scope/range relatively narrow, high 于100℃时 long and oxygen 接触会逐渐呈现黄褐 color, machine strong/high degree decline, melt and oxygen 接触极 easy hot oxidation degradation. PA1010（ nylon 1010） plastics also tool has relatively good electrical insulation property and chemical stability property, 无毒. solvent large separation non property solvent agent, 如烃, type, low grade alcohol and other, solvent understanding strong/high property solvent agent, 如苯酚, concentrated acid, acid, water combined chlorine aldehyde and other, resistant 霉菌, fine and 虫蛀.
