Isi yose - Tetrachloroéthylene ya mbere: Ikintu gikenewe cane mu nganda
Ibisabwa bikomeye
Mu bijanye n’isuku ry’ibintu vyumye, tetrachloroethylene ihagaze nk’inzahabu - igikoresho co gusukura. Ubushobozi bwayo budasanzwe bwo gusenyura ata nkomanzi kandi bukakuraho amabara menshi cane, kuva ku mavuta akomeye ku bitambaro vyiza gushika ku mwanda - intsinga zishizwemwo. Agaciro kayo kanini ka Kauri - Butanol (KB) karatuma umuntu ashobora gusukura neza, mu gihe ubumara bwayo buke cane butuma abayikoresha bashobora gukorera neza. Ivyuma bikomeye vyo gusukura imyambaro yo muri Amerika y’Uburaruko, mu Buraya no muri Aziya vyizigira tetrachloroethylene yacu kugira ngo bihe ibisubizo bitagira agasembwa, bizigame ubutungane n’ukuntu imyambaro igaragara.
Uruganda rwo gukora ivyuma na rwo nyene ruraryungukirako cane tetrachloroéthylène yacu. Kubera ko ari ikintu gikuramwo amavuta neza, kirakuraho ningoga amavuta, amavuta n’ibindi bintu bihumanye ku vyuma. Mu bikorwa vy’uguhingura imodoka mu Budagi no mu Buyapani, no mu bikorwa vy’ivy’indege muri Leta Zunze Ubumwe za Amerika, irategura ivyuma kugira ngo bikoreshwe mu bikorwa nk’ugusigira, gutera ivyuma no gusudira, ivyo bikaba bituma bifatanya neza kandi bikaba bifise akamaro. Mu gukuraho ibisigarira vyoshobora gutuma ivyuma bimera, biratuma ibihimba vy’ivyuma bimara igihe kirekire, bigatuma ibikoresho vy’iherezo bikomera.
Mu gukora imiti, tetrachloroéthylène ikora nk’ikintu nyamukuru co hagati. Ubuhinga bwayo budasanzwe bw’ibihimba vy’umubiri buratuma habaho ibintu vyinshi bikora, ivyo bikaba bituma habaho imiti idasanzwe, ivyuma bikonjesha be n’ivyuma bikorana n’ibindi bihimba vy’umubiri. Mu guhingura imiti n'ibikoresho vy'ubuhinga bwa none, ikoreshwa mu guhingura ibintu vy'ubusuku bwinshi ku bikorwa bihambaye, kugira ngo ibintu vya nyuma bibe vyiza kandi bibe vyiza. Nk’akarorero, mu guhingura amapulasitike akora neza cane yo gukoresha mu bikorwa vy’ubuhinga bwa none, ibintu biva kuri tetrachloroethylene birafasha mu gukomera kw’ibihimba vy’umubiri no guhangana n’ubushuhe.
Tetrachloroéthylène yacu na yo nyene irafise uruhara runini mu gusuzuma ibidukikije. Yemejwe nk'igisubizo c'ibintu bitera ozone, ikoreshwa mu gupima amazi n'ubutaka kugira ngo ikuremwo no gusuzuma ibintu bihumanya bishingiye ku mavuta. Ama laboratwari y’ibidukikije kw’isi yose arayizigira kugira ngo asuzume neza ingero z’ubwandu, ayobore utwigoro two gusubizaho ibidukikije no kumenya ko amategeko yubahirizwa.

Mu ncamake
Ishizwe mu bikoresho vyihariye, bitagiramwo amazi, Tetrachloroethylene yacu y’isi yose iraguma ihagaze neza mu gihe co kubika no gutwara. Itsinda ryose rirageragezwa cane kugira ngo rimenye ko risukuye, rigizwe n’ingene rikora neza. Waba uri mu bikorwa vy’ugusukura vyumye, gukora ivyuma, gukora imiti, canke gusuzuma ibidukikije, tetrachloroethylene yacu iratanga ukwizigirwa n’ubushobozi ukeneye kugira ngo ushobore gusumba abandi mu gisata cawe.
