Yooj yim muab, pvc skinned board feem ntau yog hais txog PVC skinned foam board, thaum PVC co-extruded board yog ib lub rooj tsavxwm extruded los ntawm co-extrusion ntawm ob los yog ntau tshaj cov khoom sib txawv los yog cov ntaub ntawv ntawm cov xim sib txawv.
Lub rooj tsavxwm pvc ua npuas ncauj tau muab faib ua dawb foaming thiab daim tawv nqaij foaming (ib leeg-sab tawv nqaij, ob sab tawv nqaij), thiab co-extrusion board yog co-extruded los ntawm ob lub tshuab, thiab nruab nrab tuab npuas txheej txheej tsis foamed.Hais txog kev hais lus, txheej txheej txheej ntawm co-extruded board yog ib qho nyuaj thiab muaj kev ua tau zoo dua
Ua ntej, cov txheej txheem ntau lawm ntawm ob qhov sib txawv
Ob daim ntawv pvc crusted thiab pvc co-extruded ntawv yog high-density foamed los xij, ob qho tib si uas muaj ib qho nyuaj, tab sis lawv yeej sib txawv hauv cov txheej txheem ntau lawm.Daim ntawv co-extruded xav tau ob lub tshuab ua haujlwm ua ke los tsim tawm, thiab lub rooj tsavxwm crusted tuaj yeem tsim los ntawm lub tshuab zoo tib yam, yog li ntawm tus nqi, PVC co-extruded board kuj siab.
Qhov thib ob, qhov hardness ntawm ob qhov sib txawv, qhov tom kawg yog deb tshaj qhov qub
Txhawm rau kom tau txais txiaj ntsig ntau dua, ntau lub tuam txhab siv cov ntawv crusted ua cov ntawv co-extruded, tau txais txiaj ntsig ntau ntawm tus nqi sib txawv ntawm nruab nrab, thiab rau cov neeg yuav khoom, nws yuav ua rau tsis zoo engineering, vim tias hardness ntawm co-extruded nplooj ntawv nyob deb. Loj tshaj qhov crusty ib tug.
3. Seb nws puas tuaj yeem kho nrog xim
Crusted board tuaj yeem kho nrog cov xim, thaum lub co-extruded board tsis tas yuav tsum tau pleev xim rau, thiab nws tsis tuaj yeem pleev xim rau vim tias qhov chaw du dhau lawm, thiab cov xim thiab impurities tsis tuaj yeem adsorbed ntawm nws qhov chaw.
Plaub, ib qho yog matte nto, lwm qhov yog glossy nto
PVC tawv daim ntawv yog matte tiav, thaum daim ntawv co-extruded yog glossy tiav.Qhov saum npoo ntawm co-extruded board zoo li daim iav, uas tuaj yeem cuam tshuam txhua yam khoom, tab sis lub rooj tsavxwm crusted yog matte thiab tsis tuaj yeem cuam tshuam cov khoom.Peb tuaj yeem pom meej meej los ntawm daim duab saum toj no.
Los ntawm plaub lub ntsiab lus saum toj no, nws tuaj yeem pom tias tus nqi tsim khoom ntawm pvc co-extrusion board yog siab dua li ntawm daim tawv nqaij, thiab tus nqi sib raug yog ntau dua li ntawm cov tawv nqaij.
