詳細(xì)內(nèi)容：∏PBT 2100LONG TERM SUPPLY OF PBT POLYBUTYLENE TEREPHTHALATE, ENGLISH POLYBUTYLENE TEREPHTHALATE (PBT), WHICH BELONGS TO THE POLYESTER SERIES, IS COMPOSED OF 1.4-PBT BUTANEDIOL (1.4-BUTYLENE GLYCOL) AND TEREPHTHALIC ACID (PTA) OR TEREPHTHALATE (DMT) POLY CONDENSATION, AND BY MIXING PROCEDURE MADE OF MILKY WHITE, TRANSLUCENT TO OPAQUE, CRYSTALLINE HEAT THERMOPLASTIC POLYESTER RESIN. COLLECTIVELY REFERRED TO AS THERMOPLASTIC POLYESTERS, OR SATURATED POLYESTERS, TOGETHER WITH PET. CHINESE NAME POLYBUTYLENE TEREPHTHALATE, FOREIGN NAME POLYBUTYLENE TEREPHTHALATE, ABBREVIATION PBT CLASS CHEMICALS POM 1966 ~ 2002 CHINA POM PRODUCTION CAPACITY OF THE AVERAGE ANNUAL GROWTH RATE OF 16.7%, AN AVERAGE ANNUAL GROWTH RATE OF 18.8%, VISIBLE POM MANUFACTURERS TO EXPAND DOMESTIC PRODUCTION CAPACITY IS IMPERATIVE. CHINA POM MANUFACTURER IS EXPECTED IN 2005 WILL REACH 6, THE TOTAL PRODUCTION CAPACITY WILL REACH 130 THOUSAND TONS / YEAR; (NOT REMOVE) IS EXPECTED IN 2010 CHINA POM PRODUCTION CAPACITY OF 190 THOUSAND TONS / YEAR, POM FROM 2005 TO 2010, THE PRODUCTION CAPACITY OF THE AVERAGE ANNUAL GROWTH RATE WILL REACH 7.9%. POM POM CHINA CAUSED PRODUCTIVITY GROWTH CAN NOT MEET THE DEMAND. PC, THE RESIDUAL BISPHENOL A, THE HIGHER THE TEMPERATURE, THE FASTER SPEED OF RELEASE. THEREFORE, SHOULD NOT BE "PC WATER BOTTLE FILLED WITH HOT WATER. IF YOUR KETTLE NUMBER IS 07, THE FOLLOWING METHODS CAN REDUCE THE RISK: DO NOT HEAT WHEN USING, DO NOT DIRECT IN THE SUN. DON'T USE A DISHWASHER AND A BOWL MACHINE TO CLEAN THE KETTLE. DI BEFORE USE, RINSE WITH BAKING SODA AND WARM WATER AND DRY NATURALLY AT ROOM TEMPERATURE. IF THE CONTAINER HAS ANY FALLS OR BREAKAGE, IT IS RECOMMENDED NOT TO USE IT BECAUSE THE SURFACE OF THE PLASTIC IS PRONE TO CONTAIN BACTERIA IF THERE ARE FINE PITS. AVOID REPEATED USE OF AGED PLASTIC APPLIANCES. A CUP OF LOW IS 7 CUPS ARE MADE OF POLYCARBONATE USED, I.E., PC, USED TO CALL A BISPHENOL A MATERIAL IN THE PRODUCTION PROCESS OF RAW MATERIALS IN "PC, PC" IN THE MATERIAL WILL BE MORE OR LESS EXIST BISPHENOL A MONOMER, THE HIGHER THE TEMPERATURE, THE FASTER SPEED OF RELEASE.

THE CHEMICAL AND PHYSICAL PROPERTIES OF PA6 ARE SIMILAR TO THOSE OF PA66, HOWEVER, IT HAS A LOWER MELTING POINT AND A WIDE RANGE OF PROCESS TEMPERATURES. ITS IMPACT RESISTANCE AND SOLUBILITY ARE BETTER THAN PA66, BUT ITS MOISTURE ABSORPTION IS STRONGER. BECAUSE MANY OF THE QUALITY CHARACTERISTICS OF PLASTIC PARTS ARE SUBJECT TO MOISTURE ABSORPTION, SO THE USE OF PA6 DESIGN PRODUCTS SHOULD TAKE FULL ACCOUNT OF THIS. IN ORDER TO IMPROVE THE MECHANICAL PROPERTIES OF PA6, A VARIETY OF MODIFIERS ARE OFTEN ADDED. PP BECAUSE THE HOMOPOLYMER PP TEMPERATURE IS HIGHER THAN 0C, VERY BRITTLE, SO MANY COMMERCIAL PP MATERIALS ARE 1~4% ETHYLENE RANDOM COPOLYMER OR HIGHER PROPORTION OF ETHYLENE CONTENT OF THE SEGMENT COPOLYMER. COPOLYMER TYPE PP MATERIAL HAS LOWER THERMAL DISTORTION TEMPERATURE (100C), LOW TRANSPARENCY, LOW GLOSS AND LOW RIGIDITY, BUT HAS STRONGER IMPACT STRENGTH. THE STRENGTH OF PP INCREASES WITH THE INCREASE OF ETHYLENE CONTENT.
