Kev siv tshuaj

Feem ntau 0.005% -0.05% (Raws li cov khoom hnyav)

(piv txwv li, 5 grams mus rau 50 grams ib 100 kg ntawm yas).

Lus Cim: Cov koob tshuaj tshwj xeeb yuav tsum tau hloov kho raws li qhov xav tau ntawm cov xim dawb ntawm lub substrate thiab cov khoom tuab. Rau cov yeeb yaj kiab lossis cov khoom nyias nyias - txheej txheej, qhov ntau npaum li cas yog qis dua, thaum cov khoom tuab lossis cov khoom foamed, yuav tsum muaj ntau npaum li cas.

Txoj kev ua haujlwm:
Cov khoom no yog nyob rau hauv hmoov daim ntawv. Nws yuav tsum tau muab sib xyaw ua ke nrog cov resin ua ntej siv (siv ua ntej - dispersion los yog kev sib xyaw ncaj qha) los xyuas kom meej tias lub brightener yog uniformly dispersed nyob rau hauv lub substrate yam tsis muaj agglomeration.
