Txoj kev khaws cia

1. Sodium hydroxide yog me ntsis corrosive rau iav cov khoom, thiab ob qho tib si yuav tsim sodium silicate, ua rau lub piston nyob rau hauv lub khob ntsuas ntsuas. Yog li ntawd, tsis txhob siv iav lub raj mis stopper thaum tuav cov tshuaj sodium hydroxide, txwv tsis pub nws yuav ua rau lub raj mis tsis qhib.

2. Yog tias lub khob ntim muaj cov tshuaj sodium hydroxide kub rau lub sijhawm ntev, nws tseem yuav ua rau lub khob ntim khoom puas.

3. Sodium hydroxide yuav tsum muab cia rau hauv qhov chaw txias, qhuav, zoo-ventilated warehouse. Khaws kom deb ntawm hluav taws thiab cua sov. Qhov kub ntawm lub reservoir yuav tsum tsis txhob ntau tshaj 35 ℃, thiab cov txheeb ze humidity yuav tsum tsis txhob ntau tshaj 80%. Lub pob yuav tsum raug kaw thiab tiv thaiv los ntawm ya raws. Nws yuav tsum tau muab cais los ntawm ib qho yooj yim (yuav tau) combustibles thiab acids, thiab yuav tsum tsis txhob tov.
