Pob thiab cia, kev nyab xeeb
Ntim rau hauv 200 litre galvanized hlau nruas, qhov hnyav tag nrho 220 kg / nruas.
Khaws cia rau qhov chaw qhuav, ntxoov ntxoo, thiab muaj cua nkag. Tiv thaiv kom tsis txhob muaj kev sib tsoo thiab tshav ntuj, los nag thaum lub sijhawm tuav thiab xa khoom.
Ntsib qhov kub thiab ntshiab heev lossis kov cov neeg sawv cev oxidizing, ua rau muaj kev phom sij hlawv. Yog tias ntsib qhov kub siab heev, qhov siab hauv lub thawv loj hlob, ua rau muaj kev phom sij ntawm Bang.
Yog tias daim tawv nqaij raug kov, hle cov khaub ncaws uas muaj kab mob tawm, ntxuav nrog dej ntau thiab xab npum kom huv si. Yog tias lub qhov muag raug kov, yaug nrog dej ntau thiab qhib lub qhov muag tam sim ntawd rau kaum tsib feeb. Nrhiav kev pab kho mob.
