Iphakheji nokugcinwa, ukuphepha
Igcwele ku-200 litre iron gram yensimbi, isisindo esingu-220 kg / isigubhu.
Kugcinwe endaweni eyomile, enomthunzi, enomoya opholile. Kuvinjelwe ukushayisana nangomunyu, ukuhlasela imvula ngesikhathi sokuphatha nokuthumela.
Wahlangana nomlilo oshisayo futhi ocacile noma uthintane ne-ejenti ye-oxidizing, kwabangela ingozi evuthayo. Uma kufinyelelwa ukushisa okuphezulu, ingcindezi ngaphakathi kwesitsha sanda, yabangela ingozi ye-bang.
Uma isikhumba sithintana, sikhumula izingubo ezingcolisiwe, sigezwe ngamanzi amaningi nensipho yensipho. Uma iso lithintana nalo, likhishwe ngamanzi amaningi nge-eyelid ebanjwe ivulekile ngokushesha imizuzu eyishumi nanhlanu. Thola usizo lwezokwelapha.
Pls Xhumana nathi ukuthola i-COA ne-MSDS. Ngiyabonga.
