詳細(xì)內(nèi)容： ≧PC 518RPA66 HAS A HIGH MELTING POINT IN POLYAMIDE MATERIALS. IN PRODUCT DESIGN, A PA66 CONTRACTION RATE IS BETWEEN 1%~2%. NOW ON THE MARKET CIRCULATION OF MANY DISPOSABLE NOZZLE BY MODIFICATION OF THE SAME MATERIAL CAN REACH THE ORIGINAL MATERIAL, BUT THE PRICE IS RELATIVELY CHEAPER THAN RAW MATERIALS, SO AS TO GIVE OUR CUSTOMERS A LOT OF COST SAVING. THE UNITED STATES RF-7007, RL4540 LIQUID NITROGEN DUPONT 101F, 101F-NC010, 101L, 101L-BKB009, 101L-NC010, 1032L, 103F, NC010, 103FHS, 103HSL, 10B, 10B40, 11C40-BK, 13T1 BK, 122L 408HS, 450HSL NC010, 45SHB 3426, NC 490, 408L 450, 54G15HSLR 5514, BK031 70G13HS1-L, 70G13HS1L NC010, 70G13L, 70G13SH1L, BK 70G20HSL, 70G25HSL, 70G25HSLR-BK099, 70G30HSLR, 70G33HS1-L, 70G33HS1L-NC010, 70G33HSIL (BK), 70G33HSIL (NC), 70G33L, ABS SURFACE PRETREATMENT IN ORDER TO IMPROVE THE COATING ON THE PLASTIC SURFACE ADHESION AND IMPROVE PLASTIC APPEARANCE, TO PLASTIC SURFACE PRETREATMENT BEFORE COATING. (1) WHEN ANNEALED PLASTIC ABS IS FORMED, IT IS EASY TO FORM INTERNAL STRESS, AND THE STRESS CONCENTRATION PLACE IS EASY TO CRACK AFTER COATING. ANNEALING OR WHOLE FACE TREATMENT CAN BE USED TO ELIMINATE STRESS. ANNEALING TREATMENT IS TO ABS PLASTIC MOLDING PARTS HEATING TO THERMAL DEFORMATION TEMPERATURE BELOW, THAT IS, 60 DEGREES, INSULATION 2H. IN ORDER TO REDUCE THE INVESTMENT OF THE EQUIPMENT, THE WHOLE SURFACE TREATMENT CAN BE ADOPTED TO IMPROVE THE SURFACE CONDITION. THE RECIPE AND PROCESS OF THE WHOLE TREATMENT ARE LISTED IN TABLE 1. TABLE 1 THE ENTIRE SURFACE TREATMENT PROJECT FORMULATION AND PROCESS PARAMETERS / 1 / 3 / C WATER TEMPERATURE AT ROOM TEMPERATURE THE PROCESSING TIME OF /MI15 - 20 (2) IN ADDITION TO OIL ABS PLASTIC SURFACE OFTEN ZHANYOU OIL, HAND SWEAT AND RELEASE AGENT, IT WILL MAKE THE PAINT POOR ADHESION, COATING CRACKING, BLISTERING AND SHEDDING. DEGREASING TREATMENT SHOULD BE DONE BEFORE PAINTING. THE ABS PLASTIC PARTS ARE USUALLY CLEANED WITH GASOLINE OR ALCOHOL, AND THEN CHEMICALLY REMOVED. THE RECIPE IS LISTED IN TABLE 2. TABLE 2 DEGREASING PROCESS FORMULA AND PROCESS PARAMETERS OF SODIUM HYDROXIDE (S/L) PROJECT 50 ~ 70 SODIUM PHOSPHATE (S/L) 20 ~ 30 SODIUM CARBONATE (S/L) FROM 10 TO 20 SURFACTANT (S/L) 5 ~ 10 / 50 ~ 60 DEG C TEMPERATURE PROCESSING TIME /MIN10 TO THOROUGHLY CLEAN THE RESIDUAL LYE SURFACE CHEMICAL OIL 15 ZUI, AND PURE WATER AFTER THE CLEAN, DRY OR DRYING. (3) IN ADDITION TO ELECTRICITY AND DUST REMOVAL, PLASTIC PRODUCTS ARE INSULATORS, SURFACE RESISTANCE IS GENERALLY AROUND 1013, EASY TO GENERATE STATIC ELECTRICITY. AFTER ELECTRIFICATION, IT IS EASY TO ABSORB SMALL DUST IN THE AIR AND ADHERE TO THE SURFACE. IT IS VERY DIFFICULT TO REMOVE DUST BY ELECTROSTATIC ADSORPTION BY GENERAL BLOWING METHOD. THE EFFECT OF USING HIGH PRESSURE IONIZED AIR FLOW AND REMOVING DUST AT THE SAME TIME IS BETTER. TPV THERMOPLASTIC THREE YUAN ETHYLENE PROPYLENE DYNAMIC VULCANIZATION ELASTOMER / RUBBER MAIN PERFORMANCE: TPV, EASY TO WELD, REUSABLE, ENVIRONMENTAL PROTECTION, NON-TOXIC. THE MAIN FEATURES OF THREE TPV THERMOPLASTIC DYNAMIC VULCANIZATION ELASTOMER / EPDM RUBBER: 1, EXCELLENT AGING RESISTANCE AND GOOD E AND BAD EXHAUST - MOLD PARTING SURFACE OPEN VENT ABS RESIN IS ONE OF THE FIVE MAJOR SYNTHETIC RESIN, IMPACT RESISTANCE, HEAT RESISTANCE, LOW TEMPERATURE RESISTANCE, EXCELLENT CHEMICAL RESISTANCE SCHOOL OF MEDICINE AND ELECTRICAL PERFORMANCE, ALSO HAS THE CHARACTERISTICS OF EASY PROCESSING, PRODUCT SIZE STABILITY, GOOD SURFACE GLOSS, EASY COLORING, PAINTING, BUT ALSO THE SURFACE PLATING METAL, ELECTROPLATING, WELDING, HOT PRESSING AND BONDING TWO PROCESSING, WIDELY USED IN MACHINERY, AUTOMOBILE, ELECTRICAL APPLIANCES, INSTRUMENTS, TEXTILE AND THE CONSTRUCTION INDUSTRY IS A VERY WIDELY USED THERMOPLASTIC ENGINEERING PLASTICS.
