Propylene glycol ether thiab ethylene glycol ether yog ob qho tib si diol ether solvents. Propylene glycol methyl ether muaj cov ntxhiab tsw ether me ntsis, tab sis tsis muaj ntxhiab tsw ntxhiab, uas ua rau nws siv ntau dua thiab nyab xeeb dua.
Kev siv PM CAS 107-98-2 yog dab tsi?
1. Feem ntau yog siv los ua kuab tshuaj, dispersant thiab diluent, kuj siv los ua roj antifreeze, extractant, thiab lwm yam.
2. 1-Methoxy-2-propanol CAS 107-98-2yog ib qho nruab nrab ntawm cov tshuaj herbicide isopropylamine.
3. Siv los ua hnyav, dispersant los yog diluent hauv coatings, inks, luam ntawv thiab dyeing, tshuaj tua kab, cellulose, acrylate thiab lwm yam lag luam. Nws tseem tuaj yeem siv los ua cov khoom siv raw rau cov organic synthesis.
Dej-raws li txheej thiab propylene glycol methyl ether:
Tam sim no, cov txheej txheem ntawm kev ua lag luam tuaj yeem muab faib ua cov txheej txheem dej-raws li, cov tshuaj hnyav-raws li txheej, hmoov txheej, cov txheej txheem siab, thiab lwm yam raws li lawv cov ntawv. Ntawm lawv, cov dej-raws li cov txheej txheem hais txog cov txheej txheem uas siv dej ua ib qho kev diluent. Lub volatile organic solvents yog tsawg heev, tsuas yog 5% mus rau 10% ntawm cov kuab tshuaj raws li txheej, thiab yog ntsuab thiab ib puag ncig tus phooj ywg cov khoom.
Txhawm rau ua kom cov xim ntsuab thiab ib puag ncig tus phooj ywg dej-raws li txheej, muaj cov khoom siv tshuaj tsis tseem ceeb - uas yog propylene glycol methyl ether. Lub luag hauj lwm ntawm propylene glycol methyl ether ua cov kuab tshuaj nyob rau hauv cov txheej txheem dej yog dab tsi?
(1) Dissolving dej-raws li txheej resins: propylene glycol methyl ether yog ib tug high-boiling point, low-density solvent uas yuav yaj cov resin nyob rau hauv cov dej-raws li coatings los tsim ib tug sib tov sib xyaw, yog li txhim kho cov fluidity thiab solubility ntawm dej-raws li txheej.
(2) txhim kho cov khoom siv lub cev ntawm cov dej ua haujlwm: nws muaj cov khoom siv hluav taws xob qis dua, yog li nws nce qib siab ntxiv ntawm cov txheej txheem thiab kev tswj hwm qhov ruaj khov ntawm txheej.
(3) Txhim kho cov kav dej raws li cov txheej txheem: Nws muaj cov tshuaj lom neeg ruaj khov thiab cov khoom siv antioxidant, uas tuaj yeem muab cov kav ntev thiab cov tshuaj tiv thaiv rau cov txheej txheem dej.
(4) Txo cov ntxhiab tsw ntawm cov dej-raws li cov txheej txheem: Nws muaj cov ntxhiab tsw qab, uas tuaj yeem txo cov ntxhiab tsw tawm los ntawm cov txheej txheem dej thiab txhim kho kev nplij siab thiab kev nyab xeeb ntawm cov txheej txheem.
Hauv luv luv, propylene glycol methyl ether muaj cov kuab tshuaj zoo thiab lub cev muaj zog hauv cov txheej txheem dej, uas tuaj yeem muab kev txhawb nqa tseem ceeb rau kev txhim kho kev ua tau zoo thiab ua haujlwm ntev ntawm cov txheej txheem dej. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txo qhov tsw ntawm cov dej-raws li txheej txheej thiab tso tawm cov khoom tsis zoo, thiab txhim kho kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm cov txheej txheej.
