Processing method of PPS plastic
For housing, structural parts, wear parts and sealing materials, such as: concrete pump casing, pump, valve, bearing, bearing bracket, piston ring and gear, pulley, fan, meter parts, flanges, Wan Xiangtou, counter, leveling. 2, electronic and electrical appliances: PPS for electronic and electrical appliances industry accounted for 30%, it is suitable for high temperature electrical components in the environment temperature higher than 200 DEG C; manufacturing generator and engine point rinse, rinse the electric coil, starter bracket, shield and leaf; on the TV, it can be used for high voltage shell and socket, wiring column and terminal plate; and a relay coil in the electronics industry, manufacturing transformers, resistance of the skeleton and shell, an integrated circuit carrier; using high frequency performance, manufacturing H bobbin and capacitor etc.. Micro electronic components, connectors, connector, socket, coil skeleton, Ma Dake, electromagnetic regulating plate, TV tuner shaft, relay, trimming capacitor, fuse holder, tape recorder, magnetic device and other components. Also used in precision instruments: computers, timers, speed machines, copiers, cameras, temperature sensors, and all kinds of measuring instruments shell and parts.
3, the automobile industry: PPS for automobile industry accounted for about 45%, mainly used in automotive functional parts; ignition, heater, vaporizer, clutch, gearbox, gear box, bearing bracket, lamp, bumper, fan, exhaust system and mirror and lamp seat parts. The utility model can be used for producing an exhaust cylinder, a circulation valve, a water pump impeller, a pneumatic signal adjuster, etc. in place of the metal. 4, household appliances: hot air dryer, hair curler, hair dryer, hair curler, microwave ovens, coffee pots, clothes dryers, electric irons, rice cookers and other protective coatings and parts. 5 、 chemical industry: PPS has good adhesion and corrosion resistance, it is very suitable for chemical equipment lining.Four. Material drying processTemperature: 100~105 DEG CTime: 3hr2 、 injection molding process1) die temperature: 60-80 DEG C2) material barrel temperature: front section: 220~260 centigrade middle section: 290~310 DEG C, rear section: 300~320 DEG CNozzle: 290~300 DEG C3) injection molding pressure: 60~70Mpa4) injection speed: medium speed5) injection molding time: according to the size of the workpiece to determine, in order to fill the mold, and the surface of the basic cooling is preferred
