Txheem Ntau Lawm Ntawm Wood Khoom Siv Khoom

Kev siv technology ntawm cov ntoo ntawm yas ntoo txawv heev. Nta, tsis muaj ntau yam khoom siv uas yuav siv tau rau hauv cov ntaub ntawv ntoo-yas khoom. Tam sim no, tsuas yog ib leeg-ntsia hlau extruder thiab twin-screw extruder yog xav tau.

Ib qho ntsia hlau extruder feem ntau yog ua tiav txoj hauj lwm ntawm conveying thiab yas khoom siv. Txawm li cas los xij, cov xim ib qho uas tsuas yog ib qho ciav hlau yuav tsum tau tsim tshwj xeeb ntawm cov ntsia hlau, kom nws muaj peev xwm thauj khoom nyhav thiab sib tov thiab yas, thiaj li ua kom tiav cov txheej txheem kev tov thiab granulating cov ntaub ntawv ua ntej extrusion.

Cov ntxiab-ntxiab extruder cia siab rau lub hauv paus ntawm txoj kev xaav kom thauj khoom thiab txheej txheem cov ntaub ntawv. Nws tuaj yeem ncaj qha ua cov hmoov ntoo lossis tsob nroj. Kev ziab ntawm cov hmoov noom tuaj yeem raug sib cais los ntawm cov txheej txheem melting. Conical twin-ciav hlau extruder muaj ib txoj kab uas loj tshaj ntawm qhov chaw nqus ntawm cov khoom siv sib txuas ua ke dua cov khoom siv "mixing", uas yuav ua rau cov khoom siv tsis tu ncua, ua kom lub sij hawm ntawm cov khoom nyob hauv qhov siab, hos lub cheeb ntawm qhov ntsuas seem yog qhov me me thiab cov shear ntawm cov khoom uas yaj yog me me. Qhov no yog ib qho zoo heev rau kev ua cov ntoo thermoplastic ntoo-yas khoom, yog li ntawd nws yog hu ua "profile" hom tsim nrog tsawg ceev thiab tsawg zog noj. Npaj.

Tsis tas li ntawd, lub tshuab extruder thiab lub zog txias kuj yog ib yam tseem ceeb uas muaj feem xyuam nrog cov khoom zoo ntawm cov khoom txeem. Ntxiv nrog rau txoj kev hloov thiab kev tsim nyog khiav ntawm khiav khiav, tsim ntawm lub taub ntswg kuj yuav tsum tau ua kom pom tseeb ntawm lub tsev siab muaj peev xwm thiab kev tswj qhov ntsuas ntawm qhov ntswg, thiab npaj tsim kom tau cua sov thiab cua txias ntawm lub qhov ntswg, yog li ntawd xws li ua kom txias txias thiab raug siab, thiab ua tiav lub hom phiaj ntawm kev tsim khoom zoo thiab tsim tawm.
