DINP (diisononyl phthalate) yog cov nquag siv yas tshuaj los ntawm cov esterification ntawm phthalic anhydride thiab cawv cawv isononyl. Diisononyl phthalate luv luv li DINP. Cov khoom no yog cov pob tshab ua kua nyeem nrog cov ntxhiab tsw. Cov khoom no yog lub hom phiaj dav dav yas nrog kev ua tau zoo. Cov khoom no muaj qhov sib xyaw zoo nrog PVC thiab yuav tsis los nag txawm tias nws siv nyob rau hauv ntau ntau; kev hloov pauv, tsiv teb tsaws thiab non-toxicity zoo dua li DOP (dioctyl phthalate), uas tuaj yeem muab cov khoom zoo lub teeb tsis kam, tiv tshav kub thiab laus tiv taus thiab hluav taws xob rwb thaiv tsev zoo, kev ua haujlwm tag nrho yog zoo dua DOP. Vim tias cov khoom lag luam tsim tawm cov khoom no muaj cov dej tsis kam zoo, kev tiv thaiv tawm, tsis tshua muaj tshuaj lom, kev laus tiv taus, thiab cov hluav taws xob zoo hluav taws xob, lawv tau siv dav hauv cov yeeb yaj kiab, cov xov hlau, thiab cov xaim hluav taws xob.
Piv nrog DOP, DINP muaj qhov hnyav dua qhov hnyav dua thiab cov pa roj carbon ntev dua, yog li nws muaj kev ua haujlwm zoo dua qub, ua haujlwm tiv thaiv kev tsiv teb tsaws, muaj kev tawm tsam thiab zoo dua kub. Correspondingly, nyob rau hauv tib qho xwm txheej, cov txiaj ntsig plasticizing ntawm DINP yog me ntsis kev phem dua li ntawm D0P. Nws feem ntau ntseeg tias DINP yog qhov kev tiv thaiv ib puag ncig zoo dua li DOP.
DINP muaj kev zoo tshaj hauv kev txhim kho extrusion efficiency. Nyob rau hauv kev ua cov txheej txheem ua kom tsis txhob ncua, DINP tuaj yeem txo cov yaj viscosity ntawm cov sib txuas ntau dua li DOP, uas pab txo kom tuag taus, txo cov neeg kho tshuab hnav lossis nce extrusion tsim tau (nce txog 21%). Qhov nce ntawm qhov khoom lag luam tuaj yeem tuaj yeem pom tau tias tsis hloov cov khoom lag luam thiab cov txheej txheem ntau lawm, tsis muaj peev txheej ruaj khov, tsis muaj kev siv lub zog ntxiv, thiab tswj cov khoom zoo.
Daim ntawv thov kev lag luam tshwj xeeb ntawm DOTP plasticizer: DOTP muaj cov hluav taws xob zoo thiab cov khoom cua sov. Nws tuaj yeem hloov DOP hauv PVC yas hluav taws xob xaim sheath, thiab tseem tuaj yeem siv rau hauv kev tsim cov khoom neeg tsim cov tawv ntoo cuav. Tsis tas li ntawd, nws muaj kev sib raug zoo thiab kuj tseem siv tau rau kev lag luam yas acrylonitrile derivatives, polyvinyl butyral, roj hmab, nitrocellulose, thiab lwm yam. Nws kuj tau ua lub luag haujlwm txhim kho qhov nyuaj thiab deformability ntawm cov khoom, thiab tuaj yeem siv ua tus neeg sawv cev muag hauv roj hmab, neoprene, EPDM thiab lwm yam khoom. Tshwj xeeb tshaj yog siv rau hauv cov ntaub ntawv cable, nws muaj cov txiaj ntsig zoo ua kom zoo dua thiab tsis muaj qhov tsis txaus. Nws yog dav siv nyob rau hauv ntau yam khoom uas xav tau tshav kub tsis kam thiab siab rwb thaiv tsev. Nws yog qhov zoo tshaj plaws plasticizer rau kev ua cov kub-resistant 70 ℃ cable cov ntaub ntawv thiab lwm yam khoom siv PVC uas yuav tsum muaj qhov tsis haum. Tus neeg sawv cev.
DOTP tseem siv cov roj nplua nyeem zoo los ua cov roj pleev kom zoo nkauj rau cov rooj tog thiab tha xim sab hauv tsev kho kom zoo nkauj, pleev xim thiab cov cuab yeej ua kom ncaj, nitro varnish additives, ntawv muag muag, polyester amide biaxially ncab zaj duab xis, zaj duab xis yas khoom siv tes, plasma cia hnab, thiab lwm yam Nws yog ntau yam plasticizer.
Peb lub tuam txhab tsim thiab muag cov khoom siv yas raws li dotp plasticizer, uas yog ib puag ncig zoo, tsis muaj tshuaj lom, ntsuab thiab cov pa phem, thiab txaus siab rau kev sib txuas!
