Ib qho kev sib xyaw ua vaj huam sib luag muaj 350kg ntawm cement ib lub cubic meter, yog li 5 feem pua cov xim xim los ntawm qhov hnyav ntawm cov cement yuav tsum 17.5kg ntawm cov xim.
Txhua cov xim muaj xim saturation point, dhau qhov nyiaj no, qhov nce ntxiv, qhov kawg cement khoom xim siv yuav tsis txawv ntau. Pigments nrog tus nqi tinting siab tuaj yeem ncav cuag qhov saturation ntawm cov xim nrog ntau npaum li cas.
Piv txwv li, hlau oxide dub muaj lub zog siab tshaj plaws tinting, thiab nws feem ntau yog siv hauv cov cement ntawm 6 feem pua kom ncav cuag qhov saturation. Lub zog tinting ntawm hlau oxide xim av yog me ntsis qis, thiab kwv yees npaum li cas yog 7 feem pua, ua raws li cov hlau oxide liab 8 feem pua thiab hlau daj 9 feem pua. Txawm li cas los xij, cov ntaub ntawv no yuav txawv heev nyob ntawm qhov xim ntawm txhua xim. Tam sim no, European tus qauv rau kev siv cov xim pigments hauv cov khoom cement xav kom cov xim pigments siv hauv cov cement yuav tsum tswj tsis pub dhau 10 feem pua, vim tias lub zog ntawm cov khoom cement yuav txo qis nrog cov ntsiab lus ntawm cov cement.
Dej- xim raws li: teeb tsa tus nqi tsim nyog raws li xim sib txawv. Cov khoom muaj qhov zoo dispersibility, ruaj khov cia, zoo compatibility nrog rau lwm yam khoom nyob rau hauv daim ntawv thov system, thiab yuav txhim khu lub anti{1}} xeb thiab anti- ultraviolet zog ntawm cov xim.
Cov xim pleev xim siv xim xim: primer 25--30 feem pua; sib tov xim 20--30 feem pua; enamel 15--25 feem pua (tsis suav cov pigments extender).
