Ethylene Glycol (MEG) yeAojin Chemical iri kutumirwa! Ndeapi mashandisirwo akajairika e ethylene glycol?
Ethylene glycol (MEG)chinhu chakakosha chemakemikari, uye mashandisirwo acho makuru anonyanya kutaurwa munzvimbo dzinotevera:
1. Kugadzirwa kwepolyester ndiko kushandiswa kukuru kwe ethylene glycol, iyo inokonzeresa kushandiswa kwayo kwakawanda:
Ethylene glycol inopindirana neterephthalic acid (PTA) kuburikidza nepolycondensation kugadzira polyethylene terephthalate (PET), iyo inoshandiswa kugadzira mafiber epolyester (akadai sepolyester, anoshandiswa mumachira nezvipfeko), maresini epolyester (anoshandiswa mumabhodhoro epurasitiki, mumidziyo yekurongedza, nezvimwewo), pamwe nemafirimu nemapurasitiki einjiniya.
2. Ethylene glycol inoshandiswa zvakanyanya ne antifreeze ne coolant. Nekuda kwekusatonhora kwayo kwakaderera uye kugara zvakanaka kwekupisa, inowanzoshandiswa mu automotive engine coolants (antifreeze), aircraft de-icing systems, uye se coolant mu maindasitiri.
3. Basa rekugadzirisa zvinhu uye repakati:Ethylene glycolinogona kushandiswa semushonga wekupenda, inki, dhayi, uye resins, uye zvakare senzira yekubatanidza zvigadzirwa zvakasiyana-siyana zvemakemikari, zvakaita sekugadzira ma surfactants, plasticizers, uye mafuta ekuwedzera.
Mamwe mashandisirwo emaindasitiri anosanganisira semushonga unobvisa hunyoro, mushonga wekubvisa hunyoro, mushonga unobvisa mvura mugasi (semukugadzirisa gasi rechisikigo), uye semushonga unonyorovesa kana kuti unogadzirisa viscosity muzvizoro.
