Ethylene Glycol: Musamu Uubelesyegwa Muzintu Zyiingi Akukwabilila Kutontola
Zibeela Zipati Zyakubelesya
Mumakwebo aakupanga myootokala, ethylene glycol nchintu chipati loko mukukwabilila myootokala. Chigwisya busena bwakutontola bwamaanzi, kuchitila kuti maanzi atontozyegwe kuti atatontoli muchiindi chakutontola, mpawo chisumpula busena bwakubila, kuchitila kuti injini itapya pe. Ethylene glycol-based antifreeze ilabelesyegwa kapati mukutontozya myootokala, maloli, azibelesyo zyamafakitali kuchitila kuti injini ibeleke kabotu muchiindi chakupya kapati. Kuyungizya waawo, ethylene glycol ilakonzya kukkalilila kupya akulesya kubola, zikonzya kuyungizya buumi bwazibelesyo zyakutontozya.
Mumakwebo aamisamu, ethylene glycol nchintu chiyandikana loko mukupanga zintu zipona. Ibelesyegwa kupanga polyethylene terephthalate (PET), musamu mupati wakupanga ma polyester fibers, resins, amabbodela aamapulasitiki. Ethylene glycol ilakonzya kubelesegwa kupanga zintu zyiingi zipona, zilimbuli ethylene glycol ethers, esters, antoomwe ama amines, eezyo zibelesyegwa kapati muzintu zipa kuti zintu zifwefwemale, ma coating, ma inks, ama electronic chemicals.
Mumakwebo aamisamu, ethylene glycol ibelesyegwa mbuli chintu chakusanzya akuba aakati. ilakonzya kunyonyoona zimwi zibeela zyamusamu, ikusumpula kukkalwa moyo kwamisamu. Kuyungizya waawo, ethylene glycol ilakonzya kubelesegwa kupanga misamu imwi, mbuli ethylene glycol ethers ama esters, eezyo zijisi mulimo mupati mukupanga misamu.
Mumakwebo aazisani, ethylene glycol ilabelesyegwa kupanga nsinga zya polyester. Nsinga zya polyester zilizyibidwe kuti zilaanguzu kapati, tazikonzyi kubola, alimwi zilakonzya kubamba kabotu, alimwi zilabelesyegwa kapati muzisani, muzisani zyamuŋanda, amuzisani zyamafakitali. Ethylene glycol ilaa mulimo mupati mukupanga ma polyester fibers kwiinda mukuswaangana a terephthalic acid kupanga polyethylene terephthalate (PET), eezi zipa kuti kube ma polyester fibers mabotu.
Mumakwebo aamagesi, ethylene glycol ibelesyegwa mbuli chintu chitontola. ilakonzya kubelesegwa kusalazya zibelesyo zyamagesi, kugwisya tombe azintu zyakasyeede. Kuyungizya waawo, ethylene glycol-based coolants ilabelesyegwa munzila zyakutontozya zibelesyo zyamagesi kuchitila kuti kube kupya kutazungaani muchiindi chakubeleka changuzu.
Nikuba kuti ilakonzya kubelesegwa munzila zyiingi, ethylene glycol ilakola, mpawo kubelesya akuyobolwa kuyandika nzila zyakukwabilila. Ethylene glycol ilanona, pesi kulya kulakonzya kuleta poisoni mpati, aboobo yeelede kuyobolwa kabotu kuchitila kuti bana abanyama batanjili. Mukupanga zintu mumafakitali, kubelesya ethylene glycol kanjikanji kuchitwa mumasena aajalidwe kuchitila kuti kutabi ntenda kubusena.

Mubufwaafwi
Muchi chifwiifwi, ethylene glycol, mbuli musamu uuyandika kapati, ulaa mulimo mupati mumakwebo miingi. Tachikonzyi buyo kusumpula bubotu bwazintu pesi alimwi chigwasyilizya kuyaambele kwamakwebo aamazubaano. Kakuli kuyaambele kwabusongo, nzila zyakubelesya ethylene glycol ziyooba zinji.
