Za:
Perchlorethylene, amadziwikanso kutitetrachlorethylene, ndi organic pawiri ndi formula C2Cl4 ndipo ndi madzi opanda mtundu. Yakhala gawo lofunikira munjira zosiyanasiyana zamafakitale ndi ntchito. Ngakhale kufunikira kwake, pali kusowa kwa chidziwitso cha zinthu zosunthika izi. Chifukwa chake, kuwunikira perchlorethylene, kusanthula mawonekedwe ake, kuyang'ana momwe amagwiritsidwira ntchito, komanso kumvetsetsa zokhuza chitetezo chake kunakhala kofunika. Kupyolera mu kufufuza mozama pazigawozi, pepala ili likufuna kupereka owerenga chidziwitso chokwanira cha perchlorethylene.
Makhalidwe a perchlorethylene:
Perchlorethylene ndi madzi osayaka osayaka omwe amawonetsa kukoma kokoma kwambiri. Fomula ya molekyulu ndi C2Cl4 ndipo imakhala ndi ma atomu awiri a kaboni ndi maatomu anayi a klorini. Ili ndi kukhazikika kwabwino kwambiri, yosasunthika ndi zinthu zambiri, komanso mphamvu zambiri zosungunulira.
Kugwiritsa ntchito perchlorethylene:
1. Dry Cleaning: Chimodzi mwazinthu zodziwika bwino za perchlorethylene ndi ntchito yoyeretsa youma. Kusawotcha kwake, kusungunuka kwakukulu ndi malo otentha otsika kumapangitsa kuti ikhale yabwino yosungunulira kuchotsa madontho ndi dothi ku nsalu. Kutha kwa perc kusungunula mafuta ndi zinthu zakuthupi kumatsimikizira kuyeretsa bwino popanda kuwononga zida zosalimba.
2. Metal degreasing: The mphamvu degreasing katundu perchlorethylene ndi oyenera makampani processing zitsulo. Amagwiritsidwa ntchito pochotsa mafuta, mafuta, ndi zonyansa zosafunikira kuchokera kuzitsulo zachitsulo musanayambe kukonza kapena kukonzanso pamwamba. Kugwirizana kwa perchlorethylene ndi zitsulo zosiyanasiyana, kuphatikizapo aluminiyamu, zitsulo, ndi mkuwa, zimapangitsa kuti zikhale zosungunulira zosungunulira muzitsulo zowonongeka.
3. Kupanga mankhwala: Perchlorethylene imakhala ngati mankhwala apakatikati popanga zinthu zosiyanasiyana. Imagwira ntchito ngati kalambulabwalo wa vinyl kolorayidi, yomwe imagwiritsidwanso ntchito popanga polyvinyl chloride (PVC). Kuphatikiza apo, imagwiritsidwanso ntchito popanga utoto, zomatira, mphira ndi mankhwala.
Chitetezo:
1. Chitetezo cha kuntchito: Monga momwe zimakhalira ndi mankhwala aliwonse, njira zotetezera ziyenera kuchitidwa pogwira perchlorethylene. Valani zida zoyenera zodzitetezera (PPE), monga magolovesi ndi magalasi, kuti musagwirizane. Malo ogwirira ntchito omwe ali ndi mpweya wabwino komanso makina oyeretsera mpweya ndizofunikira kuti muchepetse kukhudzana ndi mpweya wamankhwala.
2. Kukhudzidwa kwa chilengedwe: Chifukwa cha kuthekera kwake kuwononga nthaka, mpweya ndi madzi, perchlorethylene imayikidwa ngati chiwopsezo cha chilengedwe. Kusamalira bwino zinyalala ndi kutayirako zinyalala kumathandiza kwambiri popewa kuwonongeka kwa chilengedwe. Kubwezeretsanso kapena kutaya koyenera kwa perc yogwiritsidwa ntchito kumalimbikitsidwa kuti muchepetse kumasulidwa kwake ku chilengedwe.
3. Kuopsa kwa thanzi: Kutaya vinyl chloride kwa nthawi yaitali kungawononge thanzi, kuphatikizapo vuto la kupuma, chizungulire ndi khungu. Choncho, nkofunika kuti ogwira ntchito alandire maphunziro oyenerera a kasamalidwe kotetezeka komanso kuti atsatire malire omwe akhazikitsidwa.
Pomaliza:
Pomaliza, perchlorethylene ndiyofunikira kwambiri m'mafakitale angapo, makamaka pakuyeretsa kowuma, kutsitsa zitsulo komanso kupanga mankhwala. Kumvetsetsa bwino za mawonekedwe ake, magwiritsidwe ake, ndi malingaliro achitetezo ndikofunikira kuti zitsimikizike kuti zikugwiritsidwa ntchito moyenera ndikuchepetsa chiopsezo. Podziwa zinsinsi za gulu losunthikali, titha kupanga zisankho zanzeru ndikukhazikitsa malo otetezeka kuti agwiritsidwe ntchito.
