Daim ntawv thov ntawm Purified Terephthalic Acid CAS 100-21-0
Thawj hom yog dioctyl terephthalate (DOTP), uas yog cov khoom ntawm esterification cov tshuaj tiv thaiv ntawm terephthalic acid thiab industrial octanol (2-ethylhexanol). Nws yog cov yas zoo zoo nrog lub siab flash point thiab siab tshwj xeeb resistivity, tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv hluav taws xob uas muaj cua sov thiab rwb thaiv tsev;
Qhov thib ob yog polyester plasticizer, uas yog cov khoom ntawm esterification thiab condensation cov tshuaj tiv thaiv ntawm terephthalic acid thiab polyols (xws li diethylene glycol, triethylene glycol, glycerol, propylene glycol, butanediol, thiab lwm yam). Nws qhov hnyav molecular feem ntau yog nyob nruab nrab ntawm 1000-4000 (tus txheeb ze molecular hnyav ntawm polyester siv los ua plasticizer yog tsawg dua li polyester siv nyob rau hauv tshuaj fiber ntau thiab yas ntim)
Kev cia thiab kev thauj mus los
Thaum lub sij hawm kev thauj mus los, cov khoom yuav tsum tau tiv thaiv los ntawm hluav taws, noo noo thiab hluav taws xob zoo li qub. Thaum tuav cov khoom ntim khoom, lawv yuav tsum tau thauj khoom thiab tshem tawm maj mam kom tsis txhob muaj kev puas tsuaj rau lub ntim. Thaum lub sij hawm thauj khoom thiab tshem tawm kev ua haujlwm nrog cov tsheb thauj khoom, qhov ceev yuav tsum tau tswj kom tsis txhob muaj hluav taws xob zoo li qub. Cov khoom yuav tsum tau muab cia rau hauv qhov chaw txias, zoo- qhov cua thiab qhov chaw qhuav, kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Nws yuav tsum tau muab cais los ntawm oxidants thiab acids -cov khoom hauv paus. Nws yuav tsum tau tiv thaiv los ntawm tshav ntuj ncaj qha thiab los nag, thiab yuav tsum tsis txhob muab tso rau sab nraum zoov.
