Ethylene Glycol: Piny ma tiyo ku piny madwong man ma jwigo ngico
Kabedo madongo mi tic
I tic mi yiku mutukari, ethylene glycol ubedo piny madit ma nyayu lyethu. Edwoko piny rwom pa pii ma ngic, ma juku coolant ni ngic i lyethu ma piny, man edwoko piny ma ngic, ma juku engine kud lyethu. Ethylene glycol-based antifreeze jutiyu kudu lee i yub mi ngico pa mutukari, gari madongo, man jam tic mi tic pi neno ni engine tiyo maber i kare ma piny lyeth akeca. Mi medo, ethylene glycol utiye ku kero maber mi gwoko lyethu man kero mi juku lyethu, ma copo medo kwo pa piny mi ngico.
I tic mi kemikol, ethylene glycol ubedo piny ma pire tek pi yubu piny ma kwo. Jutiyo kudu pi yubu polyethylene terephthalate (PET), piny ma pire tek ma jutiyo kudu pi yubu polyester fibers, resins, man plastic bottles. Ethylene glycol copo bedu bende ni yubu piny matung tung, calu ethylene glycol ethers, esters, man amines, ma jutiyo kudu lee i solvents, coatings, inks, man electronic chemicals.
I tic mi yath, ethylene glycol jutiyu kudu calu piny ma nyayu lyethu man piny ma tiyo ikind piny. Ecopu jwigo piny moko mi yath, ma medo kero pa yath. Mi medo, ethylene glycol jucopo tiyo kudu pi yubu piny moko ma nyayu yath, calu ethylene glycol ethers man esters, ma gitiye ku tic ma pire tek i yubu yath.
I tic mi bongo, ethylene glycol jutiyu kudu pi yubu polyester fibers. Polyester fibers ungeyere pi tego migi madit, bedo ma tek, man bedo maber, man jutiyu kudu lee i bongo, bongo mi ot, man bongo mi tic. Ethylene glycol timo tic ma pire tek iyubu polyester fibers ni kadhu kud i terephthalic acid mi yubu polyethylene terephthalate (PET), ma kelo polyester fibers maber.
I tic mi cuma, ethylene glycol jutiyu kudu calu piny ma jwigo man ma jwigo. Ecopu bedu ni yweyu piny ma tiyo ku mac, kwanyu piny ma leng man madong. Mi medo, ethylene glycol-based coolants jutiyu kudu i yub mi ngico pa jam tic ma tiyo ku mac pi gwoko lyethu maber i saa mi tic ma tek.
Kadi bende tic kude i yore madwong, ethylene glycol utiye ku tho, man tic kude man gwoko pare mito gwok ma tek. Ethylene glycol utiye ku midu mamit, ento ka jucamu ecopu nyayu two marac, ci umitu jugwoke maber pi juku awiya man lei. I tic mi yubu piny, tic ku ethylene glycol pol kare timere i kabedo ma cego pi jwigu peko mi kabedu.

I thum pa lembe
I ayi ma kicoko, ethylene glycol, calu piny ma pire tek ma jutiyo kudu pi kwo, timo tic ma pire tek i tic matung tung. Ekonyo ngo kende kende tic pa piny man ber pa piny ento ekonyo bende dongo pa tic mi kare eni. Ku dongo dongo mi ryeko, tic pa ethylene glycol bibedo malac.
