Cia

1. Nws yuav tsum tau muab cia rau hauv lub ventilated, txias thiab qhuav warehouse

2. Tsis txhob khaws thiab thauj khoom ua ke nrog zaub mov, pub thiab kua qaub

 

Kev ruaj ntseg

1. ruaj khov nyob rau hauv ib txwm kub thiab siab

Cov ntaub ntawv kom tsis txhob: ya raws / noo noo oxides. Soluble nyob rau hauv ether thiab lwm yam kuab tshuaj, insoluble nyob rau hauv cawv. Solubility nyob rau hauv acid yog siab dua li nyob rau hauv dej. Nws yog decomposed nyob rau hauv alkali cawv los tsim fluoride thiab silicon dioxide. Tom qab hlawv (txog 300 degree), nws yog decomposed rau hauv sodium fluoride thiab silicon tetrafluoride. Tshuaj lom!

2. Lub solubility ntawm sodium fluorosilicate nyob rau hauv acid yog siab tshaj nyob rau hauv dej. Nws yog decomposed nyob rau hauv alkali cawv los tsim fluoride thiab silicon dioxide. Tom qab hlawv (txog 300 degree), nws decomposes los tsim sodium fluoride thiab silicon tetrafluoride. Tshuaj lom

3. Cov khoom no yog tshuaj lom thiab muaj kev cuam tshuam rau cov kab mob ua pa. Cov neeg uas raug tshuaj lom los ntawm kev noj nws qhov ncauj yuav muaj cov tsos mob ntawm plab hnyuv loj.
