Umthengisi weTetrachlorethylene (Perchlorethylene, PERC) eMzantsi Afrika
Isinyibilikisi esikhlorini esingatshiyo esinamandla okunyibilikisa iioyile, amafutha, kunye neefayibha zokwenziwa — sisetyenziswa kakhulu ekucoceni okomileyo, ukususa amafutha kumphunga, ukucoca isinyithi, kunye nokutsalwa kwe-solvent.

Yintoni iTetrachloroethylene?
I-Tetrachloroethylene (PERC, i-perchloroethylene) yi-chloroethylene e-halogenated ngokupheleleyo enefomyula i-CCl₂=CCl₂. Lulwelo oluxineneyo, olungenambala, olungatshiyo olunevumba elimnandi le-solvent. I-chlorination epheleleyo ye-PERC iyinika i-solvent ebalaseleyo kwiikhompawundi ze-organic ezingezizo ze-polar kunye ne-polar kancinci - iioyile, iigrisi, ii-waxes, iifayibha ze-polymer ezenziweyo, ii-resins, kunye nezincamathelisi - ngelixa iyenza ingatshi, inzuzo enkulu yokhuseleko kune-hydrocarbon solvents kwimisebenzi yokucoca kunye nokukhutshelwa kwemveliso ephezulu. Izinzile kakhulu phantsi kweemeko eziqhelekileyo zokuphatha xa izinzisiwe ngokufanelekileyo (ngesiqhelo ngenani elincinci le-epoxide okanye i-amine stabilizers).
Ukucoca ngoMongo kunye nokuSusa iNsimbi
Ukucoca ngokuma okubangela ukusetyenziswa okukhulu kwePERC kwihlabathi liphela: ukunyibilika kwayo kwiifayibha zokwenziwa (i-polyester, i-nylon, i-acetate), iioyile, kunye needayi, kunye nokungatshi kwayo kunye nokubuyiselwa kwayo nge-distillation, kwenze ukuba ibe lulwelo oluphambili lokucoca ngokuma okuma okuma kwaye isasetyenziswa kakhulu kwimisebenzi yokucoca ngokuma okuma eMzantsi Afrika. Kwi-metal kunye ne-parts degreasing, iPERC isetyenziswa kwiitanki zokususa amafutha omphunga ezivulekileyo kunye nezicelo zokucoca okubandayo ukususa iioyile zomatshini, ukutsala iikhompawundi, kunye neengubo ezichasene nokugqwala kwizinto zesinyithi ngaphambi kokupeyinta, ukupeyinta, okanye ukuhlanganisa. Ubuninzi bayo obuphezulu kunye nokungatshi zizibonelelo ezikhethekileyo ekususeni amafutha omphunga apho kusetyenziswa umphunga oshushu.
Imeko Yolawulo kunye Nokuphathwa Ngokukhuselekileyo
I-PERC ihlelwa njengesifo esinokubangela umhlaza ebantwini (i-IARC Group 2A) kwaye iphantsi kwemida engqongqo yokuchatshazelwa emsebenzini (ii-OEL) kunye nolawulo lokukhutshwa komoya ongcolileyo kwiindawo ezininzi. Iimatshini zokucoca ezomileyo ezivaliweyo kunye neenkqubo zokususa amafutha omphunga ezivaliweyo ziyafuneka ukunciphisa ukuvezwa kwabasebenzi kunye nokusingqongileyo. I-Terracore Chemicals inikezela nge-PERC yobuchwepheshe ezinzileyo kwiidrama kunye namaxwebhu apheleleyo okhuseleko, kubandakanya ne-SDS ehambelana nemigaqo yendawo. Sicebisa abathengi malunga nokuphathwa ngokukhuselekileyo, ukugcinwa kokuchitheka, kunye neemfuno zokuthobela imithetho yokugcina nokusetyenziswa kwe-PERC.
