Kev Siv
Dioctyl terephthalate (DOTP) yog ib qho plasticizer tseem ceeb uas muaj kev ua tau zoo heev rau polyvinyl chloride (PVC) plastics. Piv nrog rau diisooctyl phthalate (DOP) uas siv ntau, nws muaj qhov zoo ntawm kev tiv taus kub, tiv taus txias, nyuaj rau volatilize, tiv thaiv kev rho tawm, mos, thiab cov khoom rwb thaiv tsev zoo. Nws qhia tau tias muaj kev ruaj khov zoo heev, tiv taus dej xab npum thiab mos mos hauv qhov kub tsawg hauv cov khoom. Vim nws qhov tsis tshua muaj volatility, kev siv DOTP tuaj yeem ua tau raws li qhov xav tau ntawm qib kub tiv taus ntawm cov xov hlau thiab cov cables, thiab tuaj yeem siv dav hauv cov ntaub ntawv cable uas tiv taus 70° C (IEC tus qauv ntawm International Electrotechnical Commission) thiab lwm yam khoom mos PVC.
Ntxiv rau ntau cov plasticizers rau cov ntaub ntawv cable thiab PVC, DOTP kuj tseem siv tau rau hauv kev tsim cov tawv nqaij cuav. Tsis tas li ntawd, DOTP muaj cov khoom zoo heev thiab kuj siv tau ua cov plasticizers rau acrylonitrile derivatives, polyethylene, cawv butyraldehyde, roj hmab nitrile, nitrocellulose, thiab lwm yam. Nws kuj siv tau ua cov plasticizers rau roj hmab hluavtaws, cov tshuaj ntxiv rau txheej, cov roj nplua nyeem precision, cov roj nplua nyeem ntxiv, thiab cov tshuaj ua kom mos rau ntawv.
Ntim thiab Xa Khoom
Ntim: 250 kg / nruas los yog raws li cov neeg siv khoom xav tau.
Kev xa khoom: yog cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
Tshuag: muaj 500MTs kev nyab xeeb Tshuag
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
