Qhov kev ua haujlwm ntawm cov neeg sawv cev rau kev lag luam rau qhov tshuab molding yog dab tsi? Dab tsi yog qhov yuav tsum tau muaj?
Ntxiv fillers rau plastics yuav txo qhov nqi ntawm cov khoom ntawm qhov one tes thiab txhim kho tej yam khoom ntawm cov ntawm lwm yam.Piv txwv li, nws yuav ua kom lub hardness thiab rigidity ntawm cov khoom, txo lub shrinkage ntawm cov khoom, thiab ua rau kom zoo ntawm cov khoom tib lub sijhawm. Txawm li cas los xij, qhov sib ntxiv ntawm cov fillers kuj tseem tuaj yeem nqa qee qhov teeb meem rau txoj kev molding, xws li hnav dua khoom rau khoom, poob gloss ntawm cov khoom, tsis tshua xim ci, thiab lwm yam., Uas tseem txwv lawv cov tshuaj.
Lub ntsiab hom ntawm cov ntaub so ntsev yog: calcium carbonate, active calcium carbonate, av nplaum, iav fiber ntau, hmoov kua txig.
Cov uas yuav tsum tau ua rau cov fillers yog raws li nram no.
(1) zoo fineness thiab zoo dispersion.
(2) muaj peev xwm nqus tau cov yas lim.
(3) lub polymer thiab lwm tus neeg pabcuam yog neeg tsis ncaj ncees thiab tsis txhob ua tshuaj lom neeg.
(4) tsis muaj kev puas tsuaj rau kev ua haujlwm.
(5) zoo thermal stability thiab lub teeb lub zog.
(6) luv nqi.
(7) tshwj tsis yog cov ntim maub, ntog cov xim, zoo dua.
