Hauv kev tsim khoom lag luam thiab kev siv tswv yim, propylene glycol ethers yog tam sim no siv dav thiab siv cov kuab tshuaj ether. General -Lub hom phiaj ethers, sawv cev los ntawm diethyl ether thiab tetrahydrofuran, kuj muaj cov ntawv thov loj -.
Kev sib piv ntawm Daim Ntawv Thov Ntau Yam los ntawm Pawg
Propylene Glycol Ethers (Feem ntau siv)
propylene glycol ethers yog ib chav kawm ntawm cov cawv ether sib xyaw ua ke los ntawm propylene oxide, npog ntau tshaj kaum thaj chaw suav nrog kev lag luam, tshuaj niaj hnub, thiab tshuaj:
Cov ntawv thov tseem ceeb: Hauv kev lag luam coatings thiab inks, lawv tau siv los ua cov kuab tshuaj thiab cov tshuaj dispersants los kho cov qauv viscosity thiab txhim kho txheej txheej; Hauv kev lag luam hluav taws xob, lawv tau siv los ua cov khoom siv hluav taws xob hauv hluav taws xob thiab cov khoom siv hluav taws xob kom ntseeg tau tias kev ua kom huv si; Hauv kev tu thiab kev lag luam tshuaj txhua hnub, lawv tuaj yeem ua kom cov roj ua kom zoo thiab maj mam ua rau ntawm daim tawv nqaij, thiab tau dav ntxiv rau cov khoom siv hauv tsev thiab kev lag luam; nyob rau hauv kev lag luam tshuaj, lawv tuaj yeem siv rau kev tshem tawm thiab ua kom huv ntawm cov khoom xyaw tshuaj, thiab tseem tuaj yeem siv los ua cov neeg nqa tshuaj los txhim kho kev ruaj ntseg; lawv kuj tau siv tshuaj tua kab, tawv, tshuaj pleev ib ce, automotive brake fluid, thiab aircraft fuel anti-icing agents, ntawm lwm cov teb.
Cov txiaj ntsig zoo: Lub zog tawg muaj zog, tsis muaj tshuaj lom, tsis muaj zog txaus, haum rau ntau yam kev thov, ua rau nws muaj ntau hom ethers.
Diethyl Ether (Classic General-Lub Hom Phiaj Ether nrog rau Kev Siv Ntev Ntev)
Diethyl ether yog tus sawv cev tshaj plaws ether nrog keeb kwm ntev ntawm daim ntawv thov thiab tseem ua lub luag haujlwm hauv ntau qhov chaw:
Cov ntawv thov tseem ceeb: Feem ntau siv cov kuab tshuaj extraction thiab cov organic tshuaj tiv thaiv nruab nrab hauv cov chaw soj nstuam, muaj peev xwm rho tawm cov roj- cov khoom soluble los ntawm cov khoom ntuj; industrially siv nyob rau hauv zus tau tej cov rayon, guncotton, thiab nitrocellulose, thiab kuj raws li ib tug extractant rau roj thiab alkaloids; hauv kev lag luam phom phom, siv los tsim cov phom tsis muaj pa; keeb kwm feem ntau siv tshuaj loog dav dav thoob ntiaj teb, tab sis maj mam hloov pauv hauv kev kho mob.
