Peb yuav ua li cas yog tias cov granules uas tsim los ntawm kev pub noj expanding tshuab tsis sib xws?

Nyob rau hauv xyoo tas los no, cws thiab cov khoom muaj txiaj ntsig tshwj xeeb hauv dej pub tau tsim sai heev. Nyob rau hauv cov dej tshwj xeeb pub, extruded pellet pub tau dhau los ua cov khoom tseem ceeb. Kev ua haujlwm zoo ntawm cov khoom noj khoom noj uas tsim los ntawm ntau lub tuam txhab tuaj yeem sib txawv heev. Txawm tias qhov zoo ntawm tib yam khoom tsim los ntawm tib lub chaw tsim khoom hauv cov khoom sib txawv tuaj yeem hloov pauv ntau.

Cov khoom siv nthuav dav hauv cov txheej txheem kev ua haujlwm feem ntau tshwm sim cov teeb meem hauv qab no: qhov loj me me, tsis sib npaug ntev; particle porosity; particle deformation; particle hardness tsis txaus; particle dej kuj tsis zoo, viscoelasticity tsis zoo; particle incision tsis huv, beveled qhov ncauj; particle expansion expansion tsis siab, ntsib cov teeb meem saum toj no, peb yuav tsum kho cov khoom siv raws sijhawm.
