詳細內容：˙PA1010 12LONG TERM SUPPLY OF PMMA 1 APPLICATIONS: WINDOWS, BUILDING INSULATION WINDOWS, LIGHTING COVER, TELEPHONE BOOTHS AND SO ON 2 APPLICATIONS: ADVERTISING LIGHT BOXES, SIGNS, SIGNS, DISPLAY RACK AND SO ON 3 APPLICATIONS: TRAIN TRAFFIC, VEHICLE DOORS AND WINDOWS 4 MEDICAL APPLICATIONS: BABY INCUBATORS, SURGICAL MEDICAL INSTRUMENTS OF VARIOUS CIVIL PRODUCTS: SANITARY FACILITIES, HANDICRAFTS, COSMETICS, BRACKET, AQUARIUM 5 INDUSTRIAL APPLICATIONS: INSTRUMENT PANEL AND COVER 6 LIGHTING: FLUORESCENT LAMP, PENDANT LAMP, STREET LAMP, ETC. 7 HOME FURNISHING APPLICATION: FRUIT TRAY, TISSUE BOX, ACRYLIC PAINTING AND OTHER DAILY-USE PRODUCTS HOME FURNISHING THERE IS NO ENVIRONMENTAL STRESS CRACKING IN PP. USUALLY, PP IS MODIFIED BY ADDING GLASS FIBER, METAL ADDITIVE OR THERMOPLASTIC RUBBER. THE PP FLOW RATE IS MFR IN THE RANGE 1~40. THE LOW MFR PP MATERIAL HAS BETTER IMPACT RESISTANCE, BUT ITS STRENGTH IS LOWER. FOR THE SAME MFR MATERIALS, THE STRENGTH OF THE COPOLYMER TYPE IS HIGHER THAN THAT OF THE HOMOPOLYMER TYPE. AS A RESULT OF CRYSTALLIZATION, THE SHRINKAGE OF PP IS QUITE HIGH, GENERALLY 1.8~2.5%. AND THE DIRECTION UNIFORMITY OF SHRINKAGE IS MUCH BETTER THAN THAT OF PE-HD, AZ764, PP, AZ564G, AW564, PP, AV161, PP, AV161, PP, AR764, PP, AR564, PP, CA100, PP, Z451G, PP, PP, Z433,, PP, Z432. PPO HAS EXCELLENT POINT INSULATION UNDER HIGH TEMPERATURE. THE TV TUNER CHIP, COIL CORE, MICROWAVE INSULATING COMPONENT, SHIELDING SLEEVE AND HIGH FREQUENCY PRINTED CIRCUIT BOARD ARE USED. ALL KINDS OF HIGH VOLTAGE ELECTRONIC COMPONENTS, TELEVISION, COMPUTER, FAX MACHINE, REPEAT MACHINE SHELL, ETC.. AUTOMOBILE INDUSTRY: SUITABLE FOR INSTRUMENT PANEL, WINDOW FRAME, SHOCK ABSORBER, PUMP FILTER NET, ETC.. MACHINERY INDUSTRY: USED AS GEARS, BEARINGS, PUMPS, IMPELLERS, BLOWERS, IMPELLER BLADES, ETC.. CHEMICAL INDUSTRY: USED IN THE MANUFACTURE OF PIPES, VALVES, FILTERS AND SUBMERSIBLE PUMPS AND OTHER CORROSION-RESISTANT PARTS. THE DIELECTRIC CONSTANT AND DIELECTRIC LOSS TANGENT OF PPE ARE SMALLER THAN THOSE OF ZUI IN ENGINEERING PLASTICS, AND ARE ALMOST UNAFFECTED BY TEMPERATURE, HUMIDITY AND FREQUENCY. ITS VOLUME RESISTIVITY IS ZUI HIGHER THAN THAT OF ENGINEERING PLASTICS. THE EXCELLENT ELECTRICAL PERFORMANCE OF PPE WHICH IS WIDELY USED IN THE PRODUCTION OF ELECTRICAL PRODUCTS, ESPECIALLY HIGH PRESSURE RESISTANT COMPONENTS, SUCH AS THE LINE OUTPUT TRANSFORMER OF TV (FBT), MECHANICAL PROPERTIES AND GOOD THERMAL PROPERTIES: PPE CHAIN, CONTAINING AROMATIC RING STRUCTURE OF MOLECULAR CHAIN, SENSITIVITY OF STRONG, LOW SHRINKAGE, GOOD DIMENSIONAL STABILITY NON-TOXIC, LOW DENSITY. PA11 HAS GOOD FILM FORMING ABILITY AND IS USED AS CASING. IT HAS THE ADVANTAGES OF NON-TOXIC, HIGH STRENGTH, WEAR RESISTANCE AND LOW PERMEABILITY. THE MODIFIED METHOD PA11 HAS INCOMPARABLE ADVANTAGES, BUT BECAUSE OF ITS HIGH COST, IT GREATLY LIMITS THE SCOPE OF APPLICATION. NORTH CENTRAL UNIVERSITY USES THE FOLLOWING METHODS TO MODIFY PA11, GREATLY REDUCE THE COST AT THE SAME TIME ALSO RETAINS ITS UNIQUE PROPERTIES: PLASTICIZED WITH N, N- TWO METHYL TOLUENE SULFONAMIDE PLASTICIZER PA11, MECHANICAL PROPERTIES OF THE SYSTEM WERE STUDIED.
