Cov qauv txheej txheem rau ib nrab- cov khoom muag muag muag ua tiav feem ntau yog tsim los ntawm plaub yam tseem ceeb: hmoov fineness, dispersion uniformity, yias- nias thiab molding, thiab kev ruaj ntseg tswj.
Powder Fineness thiab Dispersion Standards
Cov xim pigments, mica, thiab pearlescent raw cov ntaub ntawv tau dhau los ua cov txheej txheem pulverization thiab sieving kom ntseeg tau tias qhov loj me me thiab qhov tsis muaj qhov pom ntawm cov khoom ntxhib. Thaum lub sij hawm dispersion theem, siab - sib tov ceev los yog peb - yob milling cov tswv yim feem ntau yog ua hauj lwm los xyuas kom meej cov hmoov yog muab faib tsis tu ncua thoob plaws hauv lub cev, yog li tiv thaiv tej teeb meem xws li xim patchiness los yog ntau dhau hmoov fallout. Cov txheej txheem no ua lub hauv paus tseem ceeb rau kev lav qhov muag thiab ua kom zoo ntawm cov xim them nyiaj.
Formulation Mixing and Structural Control Standards
Qhov sib piv ntawm cov roj, cov hlua khi, thiab cov hmoov yuav tsum raug tswj xyuas kom meej kom ntseeg tau tias cov khoom tiav ib nrab -cov khoom tiav muaj cov khoom zoo adhesion yam tsis muaj kev cuam tshuam rau lub lauj kaub tom ntej - nias thiab molding txheej txheem. Cov txheej txheem sib tov yuav tsum tau ua kom homogeneous thiab tsis muaj clumps, thaum tib lub sijhawm kom ntseeg tau qhov sib txawv ntawm cov xim sib txawv los tiv thaiv cov teeb meem xws li xim tsiv teb tsaws lossis stratification.
Yias-Nias thiab Stability Standards
Thaum lub sij hawm molding theem, nias siab thiab av noo theem yuav tsum tau ua tib zoo tswj kom cov hmoov qauv yog compact tab sis tsis heev compressed, yog li lav tias cov khoom yog ib qho yooj yim mus nqa nrog ib tug applicator thiab resistant rau crumbling thaum siv. Tsis tas li ntawd, cov khoom yuav tsum tau kuaj xyuas nruj heev-xws li kev tiv thaiv tshav kub, tiv thaiv txias, kev ntsuas poob, thiab kev ntsuas kev ruaj ntseg cia- kom ntseeg tau tias cov duab ntxoov ntxoo tsis tawg, tshem tawm ntawm lub lauj kaub, los yog deteriorate nyob rau lub sij hawm ntev - siv, yog li ua tau raws li cov kev cai nruj rau kev lag luam ntau lawm.
