Cov ntawv pov thawj ib puag ncig yog ua los ntawm cov ntawv xov xwm pov tseg, cov thawv ntawv, cov ntawv siv rov ua dua tshiab, cov ntaub ntawv nyoos ntoo los yog cov khoom qab zib cov ntaub so ntswg uas yog cov khoom siv raw, thiab muab sib xyaw rau hauv cov ntaub so ntswg uas ua tau raws li qhov xav tau los ntawm hydraulic pulping thiab cov khoom xyaw. Cov khoom siv thiab slurry yog lub tshuab nqus tsev-adsorbed ntawm cov pwm hlau los ua cov khoom ntub dej, uas tom qab ntawd qhuav thiab kub- nias los tsim cov khoom siv pulp.
Daim ntawv pov thawj ib puag ncig yog tsim thiab tsim raws li cov duab geometric, cov qauv kev qhia tshwj xeeb thiab kev tiv thaiv ntawm cov khoom ntim khoom xav tau. Nws muaj kev tiv thaiv zoo tshaj plaws xws li cushioning, noo noo tsis kam, compression tsis kam, poob siab tsis kam, cuam tshuam tsis kam, thiab corrosion kuj. Nyob rau hauv lub ntim ntim ntawm ntau hom khoom xws li ceramics, instruments thiab meters, electronics, mechanical parts, tool toys, glassware, mobile phones, etc., instruments thiab meters kuj tau pib maj mam siv nyob rau hauv cov khoom ntim sab nrauv, ncaj qha ntim khoom.
