Heerkulka 25 darajo Celsius, joogtaynta dielectric waa 37 Waxay u nugul tahay in la nuugo qoyaanka marka diirada la saaro.

Waxaa inta badan loo isticmaalaa wax soo saarka ee polyester polyester, resins polyester, nuuga qoyaanka, plasticizers, surfactants, fiilooyinka synthetic, isku qurxiyo iyo walxaha qarxa, iyo sidoo kale loo isticmaalaa sida dareere ah dheeh, khad, iwm, qayb ka mid ah samaynta engine antifreeze, wakiilada fuuqbaxa gaaska, for soo saaridda haragga, warqad, iyo sidoo kale waxaa loo isticmaali karaa maqaar ah. xabagta. Waxay soo saari kartaa resin synthetic PET, fiber-grade PET (ie, fiber polyester), iyo heerka xaashida PET ee samaynta dhalooyinka biyaha macdanta ah, iwm. Waxa kale oo ay soo saari kartaa resins alkyd, glyoxal, iwm., waxaana sidoo kale loo isticmaalaa sidii antifreeze. Marka laga soo tago in loo isticmaalo sida barafowga baabuurta, waxaa sidoo kale loo isticmaalaa gaadiidka awoodda qaboojinta warshadaha, guud ahaan loo yaqaan qaboojiye, isla mar ahaantaana, waxaa loo isticmaali karaa sida wakiilka qaboojinta sida biyaha.

Alaabooyinka taxanaha ethylene glycol methyl ether waa dareerayaasha organic horumarsan ee waxqabadka sare leh. Waxaa loo isticmaalaa sida dareeraha iyo dareeraha loogu talagalay daabacaadda khadadka, walxaha nadiifinta warshadaha, dahaarka (Rinjiga nitrocellulose, varnish, rinjiga dhoobada), looxyada naxaasta ah, dheehaynta, iwm.; waxaa loo isticmaali karaa sida alaabta ceeriin si loo soo saaro dhexdhexaadiyeyaasha sunta cayayaanka, dhexdhexaadiyeyaasha farmashiyaha, iyo dareeraha biriiga synthetic, iwm.; waxaa loo isticmaali karaa sida electrolyte for capacitors electrolytic, maqaar iyo fiber wakiilada dheeha, iwm. Waxa loo isticmaalaa sida kaabayaal textile, dheeha dareere synthetic, iyo alaabta ceeriin for desulfurization in Bacriminta iyo hababka sifaynta saliidda; Waxa kale oo loo isticmaali karaa sida walxaha fuuqbaxa ee wax soo saarka kiimikada.

Markaad isticmaalayso ethylene glycol sida qaboojiye, qodobada soo socda waa in la xuso

1. Barafkeeda qaboojinta waxay isbedeshaa fiirsashada ethylene glycol ee xalka aqueous. Marka fiirsashada ay ka hooseyso 60%, fiirsashada ethylene glycol ee xalka aqueous ayaa kordheysa waxaana hoos u dhacda barta qaboojinta. Si kastaba ha noqotee, marka fiirsashada ay dhaafto 60%, marka fiirsashada ethylene glycol korodho, barta qaboojinta ayaa kor u kacda iyo viscosity sidoo kale wuu kordhiyaa. Marka fiirsashada gaadho 99.9%, barta qaboojintu waxay kor u kacdaa ilaa -13.2℃. Tani waa mid ka mid ah sababaha muhiimka ah ee aan si toos ah loo isticmaali karin anti-freeze (Xalka hooyada ee ka hortagga barafka) waa in la xuso isticmaalayaasha.

2. Ethylene glycol waxa ku jira kooxo hydroxyl ah. Markaad ku shaqeyneyso 80 ° C - 90 ° C muddo dheer, ethylene glycol ayaa marka hore oksaydhid lagu gelin doonaa ethylene glycolic acid, ka dibna oxalic acid, kaas oo ah ethanedioic acid (oxalic acid), oo ka kooban 2 kooxood oo carboxyl ah. Oxalic acid iyo alaabteeda ayaa marka hore saameyn doonta habka dhexe ee neerfayaasha, ka dibna wadnaha, ka dibna kelyaha. Haddii aan la helin daaweyn habboon, qaadashada xad-dhaafka ah ee ethylene glycol waxay keeni kartaa dhimasho. Ethylene glycol ethanedioic acid waxay sababtaa daxalka qalabka iyo daadinta. Sidaa darteed, antifreeze-ka diyaarsan, waa in sidoo kale ay jiraan waxyaabo ilaaliya si looga hortago daxalka birta, aluminium iyo samaynta miisaanka.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
