Isticmaalka
Mid ka mid ah sifooyinka ugu muhiimsan iyo isticmaalka ethylene glycol waa kala duwanaanshaheeda sida dareeraha. Sida solubilizer la isku halayn karo oo hufan, waxaa si ballaaran loogu isticmaalaa warshado kala duwan. Awoodda ay u leedahay in ay ku milanto walxo kala duwan oo kala duwan ayaa ka dhigaysa shay aan lagama maarmaan u ah soo saarista polyester-ka synthetic. Haddi aad u baahan tahay in aad kala dirto dheeha, dawooyinka ama walxo kale, glycols waxa ay bixiyaan xalal sare si loo hubiyo natiijada ugu fiican ee habka wax soo saarka.
Sifo kale oo xusid mudan ee ethylene glycol waa doorkeeda sida barafka ka-hortagga. Iyada oo barta qaboojinta hoose, waxay ka hortagtaa barafku inuu ku dhex sameeyo nidaamka qaboojinta, taasoo ka dhigaysa shay lagama maarmaanka u ah hababka baabuurta ee ka hortagga barafka. Habkani waxa uu hubinayaa in mishiinkaaga iyo nidaamka qaboojintu ay ahaan doonaan kuwo shaqaynaya xitaa marka lagu jiro heerkulka eber ka hooseeya. Intaa waxaa dheer, sunta ay ku yar tahay xayawaanka waxay dammaanad qaadaysaa isticmaalka badbaadada leh ee warshadaha iyo kuwa gudaha labadaba.
Ethylene glycol wuxuu door muhiim ah ka ciyaaraa alaabta ceeriin ee isku dhafka polyesterka. Waa maadada aasaasiga ah ee wax soo saarka polyester-ka waxayna leedahay xasillooni kuleyl oo heer sare ah iyo sifooyin farsamo. Haddii aad u baahan tahay fiilooyinka synthetic, filimada ama resins, glycols waxay bixiyaan aasaaska abuurista agab waxqabad sare leh oo buuxiya baahiyaha kala duwan ee warshadaha kala duwan.
Marka la soo koobo, ethylene glycol waa iskudhis kala duwan oo leh dareere aad u fiican iyo guryaha ka-hortagga, waana shay muhiim ah oo ceeriin ah oo soo saara polyester-ka synthetic. Dabeecaddeeda midab la'aanta, ur aan lahayn, oo ay weheliso sunta yar ee xayawaanka, waxay hubisaa badbaadada iyo waxtarka codsigaaga. Glycol waxay si aan kala go 'lahayn isugu darsataa biyo iyo acetone, taasoo ka dhigaysa xalka ugu habboon baahiyahaaga dareeraha iyo ka-hortagga-barafka. La kulan faa'iidooyinka sare ee ethylene glycol oo u qaado habka wax soo saarkaaga meel sare.
