Lub neej ntev ntawm tus number case squeezing hniav yog cuam tshuam los ntawm ntau yam, feem ntau yog txij li ob peb lub hlis mus txog ib xyoos.
Ua ntej, kev siv zaus yog qhov tseem ceeb heev. Yog tias siv ntau zaus txhua hnub, nquag txhuam tus number case, cov hniav yuav hnav sai sai, ua rau lub neej luv dua li ntawm ob peb lub hlis. Piv txwv li, yog tias siv tsis tu ncua thiab tsis tu ncua, hnav yuav qeeb dua, muaj peev xwm ncua lub neej mus txog ib xyoos.
Qhov thib ob, hom number case siv kuj cuam tshuam rau cov hniav lub neej. Ntau hom number case muaj qhov sib txawv viscosity, hardness, thiab lwm yam khoom, ua rau ntau theem ntawm hnav ntawm cov hniav. Piv txwv li, qee cov kua nplaum thiab tawv tawv ua rau hnav ntau dua, ua rau lawv lub neej luv; thaum cov kua nplaum uas tsis muaj kuab thiab softer inks ua rau hnav tsawg dua thiab yuav muaj lub neej ntev dua.
Tsis tas li ntawd, cov khoom siv thiab qhov zoo ntawm cov hniav kuj cuam tshuam nws txoj sia. High- cov hniav zoo yog feem ntau ua los ntawm kev hnav- tiv taus thiab corrosion- cov ntaub ntawv resistant, muaj hardness zoo thiab toughness, zoo dua tiv taus number case hnav thiab khawb, ua rau lub neej ntev dua. Qee qhov qis dua - cov kws kho mob zoo tuaj yeem hnav thiab deform yooj yim, ua rau lub neej luv dua.
Feem ntau, lub neej ntawm tus kws kho mob tus cwj mem yog li ntawm ob peb lub hlis mus txog ib xyoos, nyob ntawm seb yam xws li kev siv zaus, hom number case, thiab cov khoom siv thiab cov hniav zoo. Txhawm rau txuas ntxiv lub neej ntawm tus kws kho mob tus cwj mem, txoj kev siv kom raug thiab ntsuas kev saib xyuas yuav tsum tau ua, xws li tsis txhob khawb ntau dhau thiab ntxuav cov kua nplaum tam sim ntawd.
