〓PA66 R0077

詳細(xì)內(nèi)容：〓PA66 R0077LONG TERM SUPPLY OF PPE RESIN HAS HIGHER MECHANICAL STRENGTH, BETTER CREEP RESISTANCE, AND LITTLE CHANGE IN TEMPERATURE. PPE HAS HIGH HEAT RESISTANCE, HIGH GLASS TRANSITION TEMPERATURE OF 211 DEG C, THE MELTING POINT OF 268 DEG C, EXCELLENT WATER RESISTANCE: PPE IS NON CRYSTALLINE RESIN, USUALLY IN THE TEMPERATURE RANGE, MOLECULAR MOTION LESS, NO POLAR GROUPS IN THE MAIN CHAIN OF LARGE, DIPOLE MOMENT IS NOT VERY, VERY GOOD WATER RESISTANCE, ZUI THE VARIETIES OF LOW WATER ABSORPTION RATE OF ENGINEERING PLASTICS. THE PHYSICAL PROPERTIES OF HOT WATER DIPPED IN HOT WATER FOR A LONG TIME ARE STILL VERY LOW PMMA ORGANIC GLASS HAS GOOD CUTTING PERFORMANCE, CAN BE IN GOOD SIZE THE SITUATION WHICH IS PROCESSED BY THE LASER CUTTING, SIMPLE AND HIGH QUALITY, THIS IS THE GLASS DOES NOT HAVE, THEREFORE CAN WITHSTAND HIGH TEMPERATURE AND LOW TEMPERATURE. ACRYLIC ENVIRONMENT IN THE PRODUCTION PROCESS, CONSUMERS DO NOT HAVE TO WORRY ABOUT THE PROBLEM OF TEMPERATURE. PA11 ARC RESISTANCE AND ELECTROCHEMICAL CORROSION RESISTANCE, USED FOR WIRE AND CABLE PROTECTIVE SLEEVE CAN IMPROVE THE RELIABILITY AND PROLONG THE SERVICE LIFE OF THE CABLE; THE PROTECTION MATERIALS USED FOR SUBMARINE CABLE, CABLE, CAN REDUCE THE SIGNAL TRANSMISSION IN THE PROCESS OF LOSS. WHEN THE GAS PIPE MADE BY PA11 IS EMBEDDED, THE JOINT CAN BE DIRECTLY BONDED WITH ADHESIVE BECAUSE OF THE LIGHT WEIGHT AND NO LIFTING DEVICE, SO THE TRANSPORTATION AND OPERATION ARE VERY CONVENIENT PPS ITSELF HAS DEMOULDING ABILITY, WITHOUT ADDING MOLD RELEASE AGENT. PPS CAN INCREASE CRYSTALLINITY AND THERMAL DEFORMATION TEMPERATURE AFTER HEAT TREATMENT, AND THE CONDITIONS OF POST-TREATMENT ARE: TEMPERATURE 204 DEG C, TIME 30MIN. PROCESSING METHOD (1) INJECTION MOLDING: THE UNIVERSAL INJECTION MOLDING MACHINE CAN BE ADOPTED AND THE MELT INDEX OF GLASS FIBER REINFORCED PPS SHOULD BE 50. INJECTION MOLDING PROCESS CONDITIONS ARE: BARREL TEMPERATURE, PURE PPS IS 280~330 DEG C, 40%GFPPS IS 300-350 DEGREES; NOZZLE TEMPERATURE; PURE PPS IS 305 DEGREES; 40%GFPPS IS 330 DEGREES; MOLD TEMPERATURE IS 120-180 DEGREES; INJECTION MOLDING PRESSURE 50-130MPA. (2) EXTRUSION: USING EXHAUST EXTRUDER, THE PROCESS IS: FEEDING SECTION TEMPERATURE IS LESS THAN 200 DEGREES; CYLINDER TEMPERATURE 300-340 DEGREES, CONNECT TEMPERATURE 320-340 DEGREES, MOLD TEMPERATURE OF 300-320 DEGREES. (3) MOLDING: SUITABLE FOR LARGE PRODUCTS, THE USE OF TWO TIMES COMPRESSION, FIRST COOLING, HOT PRESSING. THE PREHEATING TEMPERATURE OF HOT PRESSING IS ABOUT 360 PPS, 15MIN IS ABOUT 380 DEG 20MIN, AND MOLDING PRESSURE IS 10~30MPA AND COOLING IS 150 DEG GFPPS. (4) SPRAY MOLDING BY SUSPENSION SPRAYING METHOD AND SUSPENSION SPRAYING AND DRY POWDER THERMAL SPRAY MIXING METHOD IS PPS COATING TO THE METAL SURFACE, AFTER PLASTICIZING, QUENCHING AND COATING; COATING TEMPERATURE AT 300 DEG PPS, 30MIN INSULATION. LCP PLASTIC RAW MATERIALS CAN ALSO BE MADE OF ALLOY AND POLYSULFONE, PBT, POLYAMIDE BLENDS OF PLASTIC PARTS MOLDING, HIGH MECHANICAL STRENGTH, TO REPLACE THE POLYSULFONE GLASS FIBRE REINFORCED PLASTIC, WHICH CAN IMPROVE THE MECHANICAL STRENGTH, AND CAN IMPROVE THE USE STRENGTH AND CHEMICAL STABILITY ETC.. LCP IS CURRENTLY BEING USED FOR PANELS OUTSIDE THE SPACECRAFT, AUTOMOTIVE BRAKES AND SO ON.
