Kev piav txog
Dibutyl phthalate, kuj tseem yog siv dibutyl phthalate lossis dibutylfe, yog ib qho kev sib tsoo ntawm cov khoom siv ntawm 1.045 (tab sis nws yooj yim solve hauv cov kuab tshuaj muaj zog xws li Raws li Eethanol, ethere, acetone thiab benzene, thiab tseem yog miscomy nrog feem ntau hydrocarbons. Dibutyl phthalate (DIctyl phthalate (dop) thiab dibastyl philtate, uas yog cov roj hmab uas feem ntau, thiab lwm yam siv cov yas. Nws tau txais los ntawm cov thermal esterification ntawm phthalic anhydride thiab n-butanol.
Tshuaj Tshuaj Muaj Zog
Tsis muaj kob pob tshab oily kua nrog cov ntxhiab tsw ntxhiab tsw ntxhiab. Soluble nyob rau hauv ib txwm organic cov kuab tshuaj thiab hydrocarbons.
Daim ntawv thov
Kev siv tshuaj pleev ib yam li cov yas ua kom zoo rau lub ntsej muag, cov cellulose acetate, polyvinyl chloride, thiab lwm yam khoom no yog cov yas yas. Nws muaj cov zog yaj ua hwj chim rau ntau yam resins.
-Txhua ua rau PVC ua haujlwm, nws tuaj yeem muab rau cov khoom muag zoo. Vim tias nws pheej yig thiab cov txheej txheem zoo, nws yog qhov siv dav heev, yuav luag sib npaug rau dop. Txawm li cas los xij, lub volatility thiab dej extraction yog tus loj, yog li cov khoom lag luam tsis zoo, thiab nws siv yuav tsum tau txwv maj mam. Cov khoom no yog cov yas qhwv zoo ntawm nitrocellulose thiab muaj peev xwm muaj peev xwm loj heev.
-Ued rau nitrocellulose txheej, muaj cov nyhuv zoo heev. Kev ruaj khov zoo heev, siv hluav taws xob zoo, cov tshuaj nplaum thiab dej tsis kam. Ib qho ntxiv, cov khoom lag luam tuaj yeem siv los ua cov yas qhwv rau cov tawv nqaij, cov khoom siv tshuaj tsw qab, tshuaj tua kab mob, tshuaj tsw qab, ntaub roj nplua nyeem, thiab lwm yam.
- Raws li lub tshuab yas rau cellulose ester, ntsev thiab ntuj roj hmab, polystyrene; Txhawm rau ua polyvinyl chloride thiab nws cov copolymers txias-resistant rau cov khoom siv hluav taws xob organic, benzene, cov tshuaj lom neeg, cov tshuaj lom neeg, cov tshuaj tiv thaiv kab mob, ua kom muaj kuab lom Cov tebchaw thiab ntau cov pa-muaj cov lus sib txuas (cawv, aldehydes, ketones, esters, thiab lwm yam).
