I-Ethylene Glycol: Ikhemikhali Lenetinjongo Letinyenti Ne-Ejenti Yekuvikela Kubandza
Tindzawo Letinkhulu Tesicelo
Embonini yetimoto, i-ethylene glycol iyincenye lenkhulu yekulwa nekubandza. Yehlisa indzawo yekubandza kwemanti, kuvikela i-coolant kutsi ingabandza ngesikhatsi sekushisa lokuphansi, bese ikhuphula indzawo yekubila, kuvikela kushisa kakhulu kwenjini. I-antifreeze lesekelwe ku-Ethylene glycol isetjentiswa kakhulu etinhlelo tekupholisa timoto, emaloli, kanye nemishini yetimboni kucinisekisa kusebenta kwenjini lejwayelekile ngaphansi kwekushisa lokukhulu. Ngekwengeta, i-ethylene glycol inekusimama lokuhle kwekushisa kanye nekuvimbela kugcola, lokungenta imphilo yenkonzo yetinhlelo tekupholisa.
Emkhakheni wemakhemikhali, i-ethylene glycol yintfo lebalulekile leluhlata yekuhlanganiswa kwetilwane. Isetjentiselwa kukhicita i-polyethylene terephthalate (i-PET), intfo lebalulekile yekukhicita imicu ye-polyester, emaresini, kanye nemabhodlela epulasitiki. I-Ethylene glycol ingaphindze futsi isetjentiswe kuhlanganisa tinhlobonhlobo tetinhlanganisela tetilwane, njenge-ethylene glycol ethers, ema-ester, kanye nema-amine, lasetjentiswa kakhulu etinhlayiyani, ekugcobeni, ema-inki, kanye nemakhemikhali e-elekthronikhi.
Embonini yemitsi, i-ethylene glycol isetjentiswa njengesincibilikisi kanye nesisemkhatsini. Kungancibilikisa tincenye letitsite tetidzakamiva, kwenta ncono kusimamisa kanye nekuncibilika kwetidzakamiva. Ngekwengeta, i-ethylene glycol ingasetjentiswa kuhlanganisa tintfo letitsite letisemkhatsini temitsi, njenge-ethylene glycol ethers kanye nema-ester, lanekusebenta lokubalulekile ekuhlanganiseni tidzakamiva.
Emkhakheni wetindvwangu, i-ethylene glycol isetjentiswa kukhicita imicu ye-polyester. Imicu ye polyester yatiwa ngemandla ayo lamakhulu, kumelana nekugcoka, kanye nekugcina kwakheka lokuhle, futsi isetjentiswa kakhulu etimphahleni, etindvwangu tasekhaya, kanye nasetindvwangu tetimboni. iEthylene glycol idlala indzima lebalulekile ekukhiciteni imicu ye polyester ngekutsi ihlanganise ne esidi ye terephthalic kwenta i-polyester terephthalate (PET), lokuholela ekukhiciteni imicu ye polyester lesezingeni leliphakeme.
Embonini ye-elekthronikhi, i-ethylene glycol isetjentiswa njengesincibilikisi kanye nekupholisa. Ingasetjentiswa kuhlanta tincenye te-elekthronikhi, kususa kungcola lokusetulu kanye netinsalela. Ngetulu kwaloko, tintfo letipholisako letisekelwe ku ethylene glycol tisetjentiswa etinhlelo tekupholisa tetintfo te-elekthronikhi kwentela kugcina emazinga ekushisa lacinile ngesikhatsi sekusebenta lokunemtfwalo lomkhulu.
Noma nje isetjentiswa ngetindlela letiningi, i-ethylene glycol inebuthi, futsi kusetjentiswa kwayo kanye nekugcinwa kwayo kudzinga tinyatselo leticinile tekuphepha. iEthylene glycol inekunambitseka lokumnandzi, kepha kugwinya kungabangela buthi lobukhulu, ngako kumele igcinwe kahle kwentela kuvikela kufinyelela kwebantfwana netilwane. Ekukhiciteni kwetimboni, kusetjentiswa kwe ethylene glycol kuvame kwenteka etinhlelo letivaliwe kwentela kunciphisa umtselela wemvelo.

Ngalokufishane
Ngalokufishane, i-ethylene glycol, njengentfo lebalulekile yemakhemikhali laphilako, idlala indzima lebalulekile etimbonini letiningi. Akugcini nje ngekutfutfukisa kusebenta kwemkhicito kanye nelizinga kepha kuphindze kusekele kutfutfukiswa kwemboni yesimanje. Ngekuchubeka kwebuchwepheshe, ematfuba esicelo se-ethylene glycol atawuba makhulu kakhulu.
