PET Polyethylene Terephthalate Nrog CAS 25038-59-9 yog dab tsi?

PET (polyethylene terephthalate) tuaj yeem tswj tau cov khoom siv lub cev thiab cov khoom siv kho tshuab zoo heev hauv ntau qhov kub thiab txias. PET muaj kev tiv taus qaug zog zoo heev, tiv taus kev sib txhuam, tiv taus kev laus zoo heev, thiab rwb thaiv hluav taws xob zoo heev. PET ruaj khov rau feem ntau cov kuab tshuaj organic thiab cov kua qaub inorganic, muaj kev siv hluav taws xob tsawg thiab ua tau zoo. Yog li ntawd, PET tau siv dav hauv cov fwj yas ntim khoom, zaj duab xis thiab cov xov hluavtaws.

Daim Ntawv Thov

1. Cov fibers thiab cov ntaub. PET siv tau los ua polyester staple fiber thiab polyester filament, uas siv los tsim cov ntaub xws li khaub ncaws thiab rooj tog hauv tsev.
2. Kev lag luam ntim khoom. PET muaj lub luag haujlwm tseem ceeb hauv kev ntim khoom thiab feem ntau siv los tsim cov fwj dej ntxhia, cov fwj dej haus carbonated thiab lwm yam thawv. Tsis tas li ntawd, nws kuj siv los ua cov yeeb yaj kiab thiab cov ntawv rau ntim khoom noj, tshuaj, ntaub, cov cuab yeej precision thiab cov khoom siv hluav taws xob.
3. Cov khoom siv hluav taws xob thiab hluav taws xob. PET yog siv los tsim cov khoom siv hluav taws xob thiab hluav taws xob, xws li cov qhov hluav taws xob, cov khoom sib txuas hluav taws xob, cov tes tuav lub lauj kaub mov, TV bias yoke, cov thaiv davhlau ya nyob twg, cov qhov rooj breaker, cov hloov pauv, cov qhov rooj kiv cua, cov khoom siv kho tshuab, cov khoom siv suav nyiaj, cov hlau hluav taws xob, Cov khoom siv rau cov qhov cub induction thiab qhov cub, thiab lwm yam.
4. Kev lag luam tsheb. PET kuj tseem siv rau hauv kev lag luam tsheb, xws li hauv kev tsim cov twj tso kua dej, cov carburetors thiab lwm yam khoom.
5. Kev lag luam kho mob. PET-CT (positron emission computed tomography) yog ib qho thev naus laus zis siv rau kev kuaj mob thaum ntxov ntawm cov qog nqaij hlav, cov kab mob plawv, thiab lwm yam. Nws muaj cov txiaj ntsig tshwj xeeb hauv kev kuaj pom cov metabolism ntawm cov qog nqaij hlav, kev ua haujlwm thiab cov khoom ib txwm muaj.
Cov ntawv thov no qhia txog kev siv dav dav thiab qhov tseem ceeb ntawm PET ua cov khoom siv hauv ntau qhov chaw.
