    MOKHOA OA HO REKA HO RONA

    Chemwin e ka fana ka mefuta e mengata ea li-hydrocarbon tse ngata le li-solvents tsa lik'hemik'hale bakeng sa bareki ba indasteri.Pele ho moo, ka kopo bala lintlha tse latelang mabapi le ho etsa khoebo le rona: 

    1. Tshireletso

    Tšireletseho ke eona ntho e tlang pele bophelong ba rona.Ntle le ho fa bareki tlhahisoleseling mabapi le ts'ebeliso e sireletsehileng le e baballang tikoloho ea lihlahisoa tsa rona, re boetse re ikemiselitse ho netefatsa hore likotsi tsa polokeho ea basebetsi le borakonteraka li fokotsoa ho ba bonyane bo utloahalang le bo ka khonehang.Ka hona, re hloka hore moreki a etse bonnete ba hore litekanyetso tse nepahetseng tsa ho laolla le ho boloka polokeho li fihlelleha pele ho pepa ha rona (ka kopo sheba sehlomathiso sa HSSE ho latela maemo le maemo a kakaretso a thekiso ka tlase).Litsebi tsa rona tsa HSSE li ka fana ka tataiso mabapi le litekanyetso tsena.

    2. Mokhoa oa ho fana

    Bareki ba ka odara le ho fana ka lihlahisoa ho tsoa ho chemwin, kapa ba ka fumana lihlahisoa ho tsoa femeng ea rona ea tlhahiso.Mekhoa e teng ea lipalangoang e kenyelletsa lipalangoang tsa literaka, terene kapa mefuta e mengata (maemo a arohaneng a sebetsa).

    Tabeng ea litlhoko tsa bareki, re ka hlakisa litlhoko tsa likepe kapa litanka mme ra sebelisa litekanyetso tse khethehileng tsa polokeho / tlhahlobo le litlhoko.
