Qhov kev ntsuam xyuas rau cov tshuaj papermaking npog cov tshuaj pulping, ntub -kawg additives, coating chemicals, thiab functional chemicals.
Cov khoom kuaj feem ntau suav nrog peb pawg: cov khoom siv lub cev, cov khoom siv tshuaj, thiab cov khoom siv. Lub cev lub cev muaj xws li cov tsos thiab viscosity; Cov khoom siv tshuaj muaj xws li cov ntsiab lus ntawm cov khoom siv thiab txwv rau cov khoom phom sij; thiab daim ntawv thov cov khoom muaj xws li sizing℃thiab ntxiv dag zog rau cov nyhuv.
Cov txheej txheem xeem yog raws li cov qauv hauv tebchaws, cov qauv kev lag luam, thiab cov txheej txheem lees paub thoob ntiaj teb. Cov ntsuas lub cev raug ntsuas ncaj qha siv cov cuab yeej, cov ntsuas tshuaj lom neeg raug txiav txim siab siv titration tsom xam thiab cov txheej txheem spectroscopic, thiab cov khoom siv tau raug ntsuas los ntawm cov txheej txheem simulated.
Cov cuab yeej siv feem ntau suav nrog kev ntsuas ntsuas pH, ntsuas ntsuas pH, ntsuas ntsuas ntsuas, ntsuas ntsuas ntsuas, ntsuas cov ntawv ntsuas tshuab, thiab cov ntawv ntsuas lub zog.
Thib peb-kev xeem tog feem ntau muaj cov kev tsim nyog xws li CMA, CNAS, thiab ISO, thiab lub voj voog kev xeem feem ntau yog nyob ntawm 7 txog 15 hnub ua haujlwm.
