Kev Taw Qhia ntawm DOP thiab DOTP

Txheej txheem cej luam

Tej zaum yuav muaj ib txhia neeg nug tias DOP yog dab tsi thiab DOTP yog dab tsi. Puas muaj qhov sib txawv? Lawv cov txiaj ntsig thiab qhov tsis zoo ntawm lawv yog dab tsi? Cia Huisu Qinye qhia koj tias DOP thiab DOTP yog dab tsi. Tsis tas li ntawd, peb yuav ua rau koj paub zoo dua txog qhov sib txawv ntawm DOP thiab DOTP.

Dioctyl phthalate yog hu ua dioctyl ester (DOP) - ib qho organic ester compound thiab ib qho plasticizer uas siv ntau. Dioctyl phthalate yog ib qho tseem ceeb rau kev siv dav dav. Nws feem ntau yog siv rau hauv kev ua cov polyvinyl chloride resin, thiab kuj tseem siv tau rau hauv kev ua cov polymers siab xws li tshuaj fiber resin, acetic acid resin, ABS resin, thiab roj hmab. Xim, dyes, dispersants, thiab lwm yam.

DOP siv dav dav: siv dav hauv cov yas, roj hmab, xim, emulsifiers, thiab lwm yam lag luam. PVC plasticized nrog nws tuaj yeem siv los tsim cov tawv nqaij cuav, zaj duab xis ua liaj ua teb, cov ntaub ntawv ntim khoom, cov xov hlau, thiab lwm yam.

Hluav Taws Xob DOP: Ntxiv rau tag nrho cov khoom ntawm DOP dav dav, nws kuj muaj cov khoom rwb thaiv tsev zoo, feem ntau yog siv rau hauv kev tsim cov xov hlau thiab hluav taws xob.

DOP qib zaub mov: feem ntau yog siv rau hauv kev tsim cov khoom ntim khoom noj.

DOP qib kho mob: feem ntau yog siv rau kev tsim cov khoom kho mob thiab kev noj qab haus huv, xws li cov khoom siv kho mob pov tseg thiab cov ntaub ntawv ntim khoom kho mob.

DOTP

DOTP plasticizer yog lwm hom plasticizers, cov khoom no yog cov kua tsis muaj xim tsis muaj viscosity. Viscosity 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Qhov chaw khov -48°C. Qhov kub npau yog 383°C (0.1)MPa.s (0°C). Qhov chaw kub hnyiab yog 399°C. Lub npe scientific: dioctyl terephthalate. Feem ntau, peb hu nws ua DOTP.

Ntxiv rau ntau cov yas siv rau hauv cov ntaub ntawv cable thiab PVC, DOTP kuj tseem siv tau rau hauv kev tsim cov yeeb yaj kiab tawv cuav. Tsis tas li ntawd, nws muaj kev sib raug zoo heev thiab kuj tseem siv tau ua cov yas rau acrylonitrile derivatives, polyvinyl butyral, nitrile roj hmab, nitrocellulose, thiab lwm yam.

1. Cov txiaj ntsig sib txawv ntawm DOP thiab DOTP

Piv nrog rau cov dioctyl phthalate (DOP) uas siv ntau, dioctyl terephthalate (DOTP) muaj qhov zoo ntawm kev tiv taus cua sov, tiv taus txias, tsis hloov pauv, tiv thaiv kev rho tawm, yooj ywm, thiab cov khoom rwb thaiv hluav taws xob zoo. Kev ruaj khov zoo heev, tiv taus dej xab npum, thiab mos mos thaum kub tsawg.

2. Cov ntawv thov sib txawv ntawm DOP thiab DOTP

Dioctyl phthalate (DOP) yog ib qho tseem ceeb rau kev siv dav dav. Nws feem ntau yog siv rau hauv kev ua cov polyvinyl chloride resin. Txwv tsis pub, nws kuj tseem siv tau rau hauv kev ua cov polymers siab xws li tshuaj fiber resin, acetic acid resin, ABS resin, thiab roj hmab. Xim, dyes, dispersants, thiab lwm yam.

Ntxiv rau ntau cov plasticizers siv rau hauv 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 kev sib raug zoo heev. Ntxiv mus, DOTP kuj tseem siv tau ua plasticizer rau acrylonitrile derivatives, polyvinyl butyral, nitrile roj hmab, nitrocellulose, thiab lwm yam. Nws kuj tseem siv tau ua plasticizer rau roj hmab hluavtaws, cov xim ntxiv, cov roj nplua nyeem precision, cov roj nplua nyeem ntxiv, thiab ua cov khoom ua kom mos rau ntawv.
