Kev piav qhia:
Dioctyl terephthalate, tseem hu ua DOTP, yog siv los ua cov khoom siv yas hauv kev tsim cov PVC thiab lwm yam copolymers. Nws yog tus ester ntawm terephthalic acid thiab 2-ethylhexanol. Nws yog cov kua ntshiab, tsis muaj xim nrog me ntsis tsw, uas tsis yaj hauv dej. DOTP tuaj yeem siv los hloov DOP thiab DINP ncaj qha rau ntau yam kev siv vim nws tiv taus cua sov, ua haujlwm tau zoo heev thiab pob tshab. Nws yog siv rau hauv ntau yam txheej txheem xws li calendering, extrusion thiab txhaj tshuaj molding.

Kev Siv
Nws yog siv feem ntau ua cov yas rau polyvinyl chloride thiab lwm yam polymers.
DOTP tuaj yeem tsim cov khoom sib xyaw nrog polyaniline (PANI) -ethyene dimethacrylate (EDMA), uas tuaj yeem siv rau hauv kev tsim cov yeeb yaj kiab conductive. Nws kuj tseem siv tau ua cov yas nrog polyvinyl chloride (PVC) los tsim cov tshuaj rau cov quav hniav cuav hauv cov hlab ntsha.
Ntim thiab Xa Khoom
200KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
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.
