The ulo oru na mmepụta nke ethylene glycol

Ethylene glycol - bụ a ubé viscous, mmanu mmanu, odorless mmiri mmiri. Ọ bụ nke ukwuu soluble na alcohols, mmiri, acetone na turpentine. Ethylene glycol bụ ihe ndabere maka akpakanamde antifirizi na ezinụlọ ebe ọ lowers fọrọ maka kefriza nke mmiri na okenye agbanwe agbanwe. Ihe na-akpali eziokwu bụ na ọbụna oyi kpọnwụrụ mmiri mmiri na-adịghị na gwọrọ, mbịne n'ime ice, na dị nnọọ na-aghọ rụrụ. Ọzọkwa, okenye agbanwe agbanwe nke ethylene glycol anaghị mụbaa na Ya mere adịghị imebi akpa na igwe okpomọkụ na ụgbọala.
