Propylene glycol ether thiab ethylene glycol ether yog ob qho tib si diol ether solvents. Propylene glycol methyl ether muaj me ntsis tsw ntawm ether, tab sis tsis muaj ntxhiab tsw khaus heev, uas ua rau nws siv dav dua thiab muaj kev nyab xeeb dua.
PM CAS 107-98-2 siv tau li cas?
1. Feem ntau siv ua cov kuab tshuaj, cov tshuaj dispersant thiab diluent, kuj siv ua roj antifreeze, extractant, thiab lwm yam.
2. 1-Methoxy-2-propanol CAS 107-98-2yog ib qho nruab nrab ntawm cov tshuaj tua kab isopropylamine.
3. Siv ua cov kuab tshuaj, cov tshuaj tawg lossis cov tshuaj diluent hauv cov tshuaj pleev xim, cov kua mem, cov ntawv luam ntawv thiab cov xim zas xim, cov tshuaj tua kab, cellulose, acrylate thiab lwm yam lag luam. Nws kuj tseem siv tau ua cov khoom siv raw rau cov organic synthesis.
Cov txheej txheem dej thiab propylene glycol methyl ether:
Tam sim no, cov txheej txheej hauv khw muaj peev xwm muab faib ua cov txheej txheej dej, cov txheej txheej ua los ntawm cov kuab tshuaj, cov txheej txheej hmoov, cov txheej txheej ruaj khov, thiab lwm yam raws li lawv cov duab. Ntawm lawv, cov txheej txheej dej yog hais txog cov txheej txheej uas siv dej ua cov tshuaj yaj. Cov kuab tshuaj organic uas tsis yaj tau yooj yim heev, tsuas yog 5% txog 10% ntawm cov txheej txheej ua los ntawm cov kuab tshuaj, thiab yog cov khoom ntsuab thiab zoo rau ib puag ncig.
Yuav ua kom cov xim pleev xim uas yog dej ntsuab thiab tsis ua rau ib puag ncig puas tsuaj, muaj ib yam khoom siv tshuaj lom neeg tseem ceeb uas tsis tuaj yeem tsis tau - uas yog propylene glycol methyl ether. Lub luag haujlwm ntawm propylene glycol methyl ether ua cov kuab tshuaj hauv cov xim pleev xim uas yog dej yog dab tsi?
(1) Yaj cov tshuaj pleev xim dej: Propylene glycol methyl ether yog cov tshuaj uas kub heev, cov tshuaj uas tsis kub heev uas tuaj yeem yaj cov tshuaj pleev xim hauv cov tshuaj pleev xim dej kom ua rau muaj kev sib xyaw ua ke, yog li ua kom cov kua dej thiab cov tshuaj pleev xim dej yaj tau zoo.
(2) Txhim kho cov khoom siv lub cev ntawm cov txheej txheem dej: Nws muaj qhov ceev qis dua thiab siab dua pa, yog li nws tuaj yeem txhim kho cov khoom siv lub cev ntawm cov txheej txheem dej, xws li ua kom cov viscosity ntawm cov txheej txheem thiab tswj kev ruaj khov ntawm cov txheej txheem.
(3) Txhim kho qhov ruaj khov ntawm cov txheej txheem dej: Nws muaj kev ruaj khov tshuaj lom neeg zoo thiab cov khoom antioxidant, uas tuaj yeem muab kev ruaj khov zoo thiab kev tiv thaiv tshuaj lom neeg rau cov txheej txheem dej.
(4) Txo cov ntxhiab tsw ntawm cov txheej txheej dej: Nws muaj ntxhiab tsw qis dua, uas tuaj yeem txo cov ntxhiab tsw uas cov txheej txheej dej tso tawm thiab txhim kho kev nplij siab thiab kev nyab xeeb ntawm cov txheej txheej.
Hauv ntej, propylene glycol methyl ether muaj cov khoom zoo rau kev yaj thiab cov khoom siv lub cev hauv cov txheej txheem dej, uas tuaj yeem muab kev txhawb nqa tseem ceeb rau kev txhim kho kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov txheej txheem dej. Tib lub sijhawm, nws kuj tseem tuaj yeem txo qhov tsw ntawm cov txheej txheem dej thiab kev tso tawm cov tshuaj lom neeg, thiab txhim kho kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm cov txheej txheem.
