Codsiyada PERCHLORETHYLENE

Warshadaha, PERCHLORETHYLENE waxaa inta badan loo isticmaalaa sida dareeraha, isku-dhafka organic, nadiifiyaha dusha birta iyo wakiilka nadiifinta qalalan, desulfurizer, dhexdhexaadinta kulaylka.Waxa loo isticmaalaa daawaynta sida anthelmintic.Sidoo kale waa dhexdhexaad trichlorethylene iyo walxaha organic fluorinated.Deganeyaasha guud waxa laga yaabaa inay la kulmaan xaddi hoose oo tetrachlorethylene iyada oo loo marayo jawiga, cuntada iyo biyaha la cabbo.Tetrachlorethylene waxay leedahay milmayn wanaagsan oo loogu talagalay xeryahooda organic iyo organic badan, sida baaruud, iodine, chloride mercuric, aluminium chloride, baruur, caag iyo xabagta, milanka noocan oo kale ah ayaa si ballaaran loo isticmaalaa sida wakiilka nadiifinta birta, wakiilka rinjiga, wakiilka nadiifinta qalalan, dareeraha caagga ah. , dareere khad, saabuun dareere ah, dhogorta heerka sare ah iyo baalasha xaalufinta;Tetrachlorethylene waxa kale oo loo istcimaalaa ka celis ahaan (hooworm iyo gooryaanka sinjibiil);Wakiilka dhamaystirka ee farsamaynta dharka.
1. Loo isticmaalo sida dareeraha organic, wakiilka nadiifinta qalalan, wakiilka soo saarista saliidda, wakiilka qiiqa, desulfurizer iyo wakiilka dhamaystiraya dharka, iwm
2. Tetrachlorethylene ayaa si weyn loo isticmaalaa, inta badan waxaa loo isticmaalaa sida dareeraha organic, wakiilka nadiifinta qalalan, dareere biraha xaalufiyo, iyo sidoo kale loo isticmaalo sida enteroinsect repellent.Tetrachlorethylene waxaa loo isticmaali karaa sidii soosaar dufan ah, wakiilka dabka iyo wakiilka qiiqa, waxaana sidoo kale loo isticmaali karaa in lagu farsameeyo trichlorethylene iyo xeryahooda organic fluorinated.
3. Loo isticmaalo sida dareere organic, wakiilka nadiifinta qalalan, desulfurizer iyo wakiilka dhamaystirka dharka
4. Tetrachlorethylene si weyn ayaa loo isticmaalaa, inta badan waxaa loo isticmaalaa sida dareeraha organic, wakiilka nadiifinta qalalan, dareere xaalufinta biraha, sidoo kale loo isticmaalo sida enteroinsect ka celiya dareere daawaynta, qalabka falanqaynta chromatographic caadiga ah.Tetrachlorethylene waxaa loo isticmaali karaa sidii soosaar dufan ah, wakiilka dabka iyo wakiilka qiiqa, waxaana sidoo kale loo isticmaali karaa in lagu farsameeyo trichlorethylene iyo xeryahooda organic fluorinated.
5. Walxaha loo isticmaalo sidii dufan ama walax u eg baruurta marka lagu jiro falanqaynta dabiiciga ah.Cadaadis sare oo dareere ah chromatography.Xalka loogu talagalay go'aaminta spectrophotometric.Isku-dhafka dabiiciga ah.
