Gabatarwar samfur da fasaloli

CH2OH 2, wanda shine mafi sauƙin diol. Ethylene glycol ruwa ne mai daɗi mara launi, mara ƙamshi, mai ƙarancin guba ga dabbobi. Ethylene glycol na iya narkewa tare da ruwa da acetone, amma ƙarfinsa a cikin ethers ƙarami ne. Ana amfani da shi azaman mai narkewa, hana daskarewa da kuma kayan polyester na roba. Polymer na ethylene glycol, polyethylene glycol (PEG), shine mai haɓaka canja wuri na lokaci kuma ana amfani da shi a cikin haɗakar ƙwayoyin halitta.

amfani

Ana amfani da shi galibi don yin polyester, polyester, resin polyester, mai sha danshi, mai plasticizer, wakili mai aiki a saman, zare na roba, kayan kwalliya da abubuwan fashewa, kuma ana amfani da shi azaman mai narkewa don rini, tawada, da sauransu, shirya wakilin hana daskarewa na injin, wakilin bushewar iskar gas, resin masana'antu, kuma ana iya amfani da shi don cellophane, zare, fata, wakilin jika manne. Yana iya samar da resin roba PET, zare PET wanda shine zare na polyester, yanke kwalba PET don yin kwalaben ruwan ma'adinai da sauransu. Hakanan yana iya samar da resin alkyd, glyoxal, da sauransu, wanda kuma ana amfani da shi azaman maganin daskarewa. Baya ga amfani da shi azaman maganin daskarewa ga motoci, ana kuma amfani da shi don jigilar ƙarfin sanyaya masana'antu, wanda galibi ake kira refrigerant mai ɗaukar kaya, kuma ana iya amfani da shi azaman wakilin haɗawa kamar ruwa.
Kayayyakin jerin Ethylene glycol methyl ether masu ƙarfi ne na halitta, kamar tawada ta bugawa, wakilin tsaftacewa na masana'antu, shafi (fentin nitro fiber, varnish, enamel), faranti mai rufi da jan ƙarfe, abubuwan narkewar bugu da rini da abubuwan narkewa; Ana iya amfani da shi azaman kayan masarufi don samfuran sinadarai kamar magungunan kashe kwari, magungunan tsakiya da ruwan birki na roba. A matsayin electrolytes don capacitors na electrolytic, wakilin rini na fiber na sinadarai don tanning, da sauransu. Ana amfani da shi azaman mataimakan yadi, rini na ruwa na roba, da kuma taki da tace mai wajen samar da kayan masarufi na desulfurizer.
Ya kamata a lura da Ethylene glycol lokacin amfani da shi azaman mai ɗaukar kayan sanyaya:
1. Wurin daskarewa yana canzawa tare da yawan ethylene glycol a cikin ruwan magani. Idan yawan ruwan ya kasance ƙasa da kashi 60%, wurin daskarewa yana raguwa tare da karuwar yawan ethylene glycol a cikin ruwan magani, amma idan yawan ruwan ya wuce kashi 60%, wurin daskarewa yana ƙaruwa tare da karuwar yawan ethylene glycol, kuma danko yana ƙaruwa tare da karuwar yawan ruwan magani. Lokacin da yawan ruwan ya kai kashi 99.9%, wurin daskarewarsa yana ƙaruwa zuwa -13.2℃, wanda shine muhimmin dalili da yasa ba za a iya amfani da maganin daskarewa mai ƙarfi (ruwa mai hana daskarewa) kai tsaye ba, kuma dole ne ya jawo hankalin mai amfani.
2. Ethylene glycol ya ƙunshi rukunin hydroxyl, wanda za a haɗa shi da glycolic acid sannan a haɗa shi da oxalic acid, wato glycolic acid (oxalic acid), wanda ke ɗauke da ƙungiyoyin carboxyl guda biyu, lokacin da yake aiki a zafin 80-90 ℃ na dogon lokaci. Oxalic acid da abubuwan da ke cikinsa suna shafar tsarin jijiyoyi na tsakiya da farko, sannan zuciya, sannan koda. Ethylene glycol glycolic acid, wanda ke haifar da tsatsa da zubewar kayan aiki. Saboda haka, a cikin shirye-shiryen hana daskarewa, dole ne a sami wani abu mai kiyayewa don hana tsatsa na ƙarfe, aluminum da samuwar sikelin.
