9. Raws li ib tug additive nyob rau hauv zus tau tej cov ntaub ntawv sealing thiab nres pads, nws plays lub luag hauj lwm nyob rau hauv muaj zog hnav tsis kam;
10. Raws li additives hauv pob zeb, txhim khu kev tiv thaiv corrosion ntawm pob zeb.
Cov kev ceev faj:
1. Siv sodium fluoride los tswj cov tshuaj fluorine txhua hnub kom nruj kom tsis txhob muaj cov tshuaj fluoride lom;
2. Sodium fluoride tov los yog gel yuav tsum muab tso rau hauv lub thawv yas;
3. Cov neeg mob, cov poj niam cev xeeb tub, cov poj niam cev xeeb tub, cov pob txha mos thiab lub raum tsis ua haujlwm nyob rau hauv cov cheeb tsam siab-fluoride raug txwv.
