Umhlaba wonkhe - I-Tetrachloroethylene Leyinhloko: Sincibilikisi Lesibalulekile Setimboni
Tindzawo Letinkhulu Tesicelo
Embonini yekuhlanta leyomile, i-tetrachlorethylene ime njengeligolide - lesincibilikisi lesijwayelekile. Kuncibilika kwayo lokukhetsekile ngaphandle kwemzamo kuphuka futsi kususa tinhlobo letiningi temabala, kusuka kumafutsa lanenkhani etindvwangu letincane kuya ekungcoleni - imicu lefakwe ngaphakathi. Linani layo leliphakeme le Kauri - Butanol (KB) licinisekisa kuhlantwa lokuphelele, kantsi iphrofayli yayo lephansi yebuthi iniketa indzawo yekusebenta lephephile kubasebentisi. Emaketanga lamakhulu ekuhlanta lomile eNyakatfo Melika, eYurophu, nase Asia atsembele ku tetrachlorethylene yetfu kuletsa imiphumela lengenasici, kugcina bucotfo kanye nekubukeka kwetingubo letibucayi.
Umkhakha wekusebenta ngensimbi nawo uyazuza kakhulu ku-tetrachloroethylene yetfu. Njengendlela lesebenta kahle yekususa emafutsa, isusa ngekushesha emafutsa, tintfo tekugcobisa kanye naletinye tintfo letingcolisako letisetinsimbini. Etikhungweni tekukhicita timoto eJalimane naseJapan, kanye netikhungo te-aerospace eMelika, ilungiselela tinsimbi tetinchubo letifana nekupenda, kufaka, kanye nekushisela, kucinisekisa kunamatsela lokusezingeni leliphakeme kanye nelizinga lemkhicito. Ngekucedza tinsalela letingabangela kugcola, kwelula sikhatsi sekuphila kwetincenye tensimbi, kwenta ncono kucina kwemikhicito yekugcina.
Ekuhlanganisweni kwemakhemikhali, i-tetrachlorethylene isebenta njengentfo lebalulekile lesemkhatsini. Isakhiwo sayo lesehlukile se-molecule sivumela kutsi kube nekuphendvula lokunyenti, kwenta kutsi kukhicitwe emakhemikhali lakhetsekile, emafriji, kanye nema-polymer. Ekukhiciteni imitsi kanye ne-elekthronikhi, isetjentiselwa kwenta tintfo letisetulu - letihlantekile tetinchubo letibucayi, kucinisekisa kuciniseka kanye nelizinga lemikhicito yekugcina. Sibonelo, ekukhiciteni emapulasitiki lasebenta kahle kakhulu embonini ye-elekthronikhi, emakhompawundi lasuselwa ku-tetrachlorethylene afaka sandla ekuciniseni kwetincenye kanye nekumelana nekushisa.
I-tetrachlorethylene yetfu iphindze idlale indzima lebalulekile ekuhlaziyeni imvelo. Ivunywe njengentfo letsatsa sikhundla se ozone - tintfo leticedzako, isetjentiswa ekuhlolweni kwemanti kanye nemhlabatsi kukhipha nekuhlatiya tintfo letingcolisako letisekelwe ku oyili. Emalabhorethri emvelo emhlabeni wonkhe atsembele kuwo kutsi ahlole kahle emazinga ekungcola, acondzise imizamo yekulungisa kanye nekucinisekisa kulandzelwa kwemtsetfo.

Ngalokufishane
Ipakishwe etitjani letikhetsekile, letivuzako, iTetrachlorethylene yetfu yeMhlaba wonkhe - Leyinhloko igcina kusimamisa kwayo ngesikhatsi sekugcina kanye nekutfutsa. I-batch ngayinye idlula ekuhlolweni lokucinile kwekuhlanteka, kwakheka, kanye nekusebenta. Noma ngabe usekuhlanteni lokomile, kusebenta ngensimbi, kukhicita emakhemikhali, noma kuhlatiya imvelo, i-tetrachlorethylene yetfu iniketa kwetsembeka kanye nekusebenta lokudzingako kutsi uphumelele embonini yakho.
