Gabatarwar samfur da fasali

CH2OH 2, wanda shine mafi sauƙin diol.Ethylene glycol ruwa ne mara launi, mara wari, mai dadi tare da ƙarancin guba ga dabbobi.Ethylene glycol na iya zama mai narkewa tare da ruwa da acetone, amma solubility a cikin ethers kadan ne.Ana amfani dashi azaman ƙarfi, maganin daskarewa da ɗanyen polyester roba.A polymer na ethylene glycol, polyethylene glycol (PEG), shi ne wani lokaci canja wurin mai kara kuzari kuma ana amfani da shi a cikin cell Fusion.

amfani

Yafi amfani ga yin polyester, polyester, polyester guduro, danshi absorbent, plasticizer, surface aiki wakili, roba fiber, kayan shafawa da fashe, da kuma amfani da a matsayin sauran ƙarfi ga dyes, tawada, da dai sauransu, shirye-shiryen na engine antifreeze wakili, gas dehydrating wakili, guduro masana'anta, kuma za'a iya amfani dashi don cellophane, fiber, fata, manne wetting wakili.Yana iya samar da roba guduro PET, fiber PET cewa shi ne polyester fiber, kwalban yanki PET domin yin ma'adinai ruwa kwalabe da sauransu.Hakanan za'a iya samar da resin alkyd, glioxal, da sauransu, kuma ana amfani dashi azaman maganin daskarewa.Bugu da ƙari, ana amfani da shi azaman maganin daskarewa don motoci, ana kuma amfani da shi don jigilar ƙarfin sanyaya masana'antu, wanda ake kira dako refrigerant, kuma ana iya amfani da shi azaman ma'auni kamar ruwa.
Ethylene glycol methyl ether jerin kayayyakin ne high quality Organic kaushi, kamar bugu tawada, masana'antu tsaftacewa wakili, shafi (nitro fiber Paint, varnish, enamel), jan karfe mai rufi farantin, bugu da rini kaushi da diluents;Ana iya amfani da shi azaman albarkatun ƙasa don samfuran sinadarai kamar masu tsaka-tsakin magungunan kashe qwari, magungunan magunguna da ruwan birki na roba.Kamar yadda electrolytes for electrolytic capacitors, sinadaran fiber rini wakili ga tanning, da dai sauransu Amfani da yadi auxiliaries, roba ruwa dyes, kazalika da taki da mai tacewa a samar da desulfurizer albarkatun kasa.
Ethylene glycol ya kamata a lura lokacin amfani da shi azaman refrigerant mai ɗaukar hoto:
1. Matsayin daskarewa yana canzawa tare da tattarawar ethylene glycol a cikin maganin ruwa.Lokacin da maida hankali ya kasance ƙasa da 60%, wurin daskarewa yana raguwa tare da haɓaka haɓakar ethylene glycol a cikin maganin ruwa mai ruwa, amma lokacin da maida hankali ya wuce 60%, wurin daskarewa yana ƙaruwa tare da haɓaka haɓakar ethylene glycol, da danko. yana ƙaruwa tare da haɓaka haɓakawa.Lokacin da maida hankali ya kai kashi 99.9%, wurin daskarewa ya tashi zuwa -13.2 ℃, wanda shine muhimmin dalilin da yasa ba za a iya amfani da antifreeze mai daskare ba kai tsaye, kuma dole ne ya jawo hankalin mai amfani.
2. Ethylene glycol yana dauke da rukunin hydroxyl, wanda za'a sanya oxidized zuwa glycolic acid sannan kuma zuwa oxalic acid, wato glycolic acid (oxalic acid), yana dauke da kungiyoyin carboxyl guda 2, idan yana aiki a 80-90 ℃ na dogon lokaci.Oxalic acid da abubuwan da ke cikinsa suna shafar tsarin tsakiya na tsakiya, sannan zuciya, sannan kuma kodan.Ethylene glycol glycolic acid, yana haifar da lalata da zubar da kayan aiki.Sabili da haka, a cikin shirye-shiryen maganin daskarewa, dole ne a sami abin kiyayewa don hana lalata karfe, aluminum da samuwar sikelin.
