1. Tshem tawm cov plua plav thiab av ntawm qhov chaw ntawm lub substrate ua ntej kev tsim kho.
2. Thaum siv, do cov xim kom huv si nrog ib tug stirrer, tshuaj tsuag los yog txhuam.
3. Txhawm rau kom ntseeg tau qhov adhesion ntawm cov txheej, nws yog ib qho tsim nyog yuav tsum tau qhuav nws ua ntej siv cov tom ntej.
4. Kev tsim kho ib puag ncig kub yog qhov zoo dua 5-38 ° C, thiab qhov txheeb ze av noo yog <85%.
5. Kev siv theoretical ntau npaum li cas: 500g / m2.
Lub hauv paus kub tsis tsawg tshaj 0 ℃, thiab tsawg kawg yog saum huab cua dew point kub 3 ℃, tus txheeb ze av noo ntawm 85% (kub thiab txheeb ze av noo yuav tsum tau ntsuas ze ntawm lub hauv paus khoom), pos huab, nag, daus, cua thiab nag yog txwv tsis pub tsim kho.
