Kev siv cov polystyrene (PS) resin ua cov khoom siv raw, cov neeg ua haujlwm tawv, cov stabilizers, fillers, thiab cov khoom siv tsim nyog tau muab tso ua ke raws li cov khoom siv tshwj xeeb. Cov khoom xyaw no tau muab sib xyaw ua ke siv cov khoom siv sib xyaw ua ke siab - nrawm kom ntseeg tau tias cov khoom sib xyaw ua ke ntawm txhua yam khoom xyaw, yog li lav qhov kev ua haujlwm ruaj khov thiab ua haujlwm zoo ib yam nyob rau theem tom ntej.
Cov khoom sib xyaw yog pub rau hauv extruder, qhov twg, nyob rau hauv kev sib xyaw ua ke ntawm siab - kub cua sov thiab ntsia hlau shearing, nws maj mam melts thiab plasticizes los ua ib homogeneous yaj. Cov yaj no ces extruded los ntawm ib tug tshwj xeeb tuag los tsim ib tug board -zoo li qauv. Thaum lub sijhawm txheej txheem no, tus tsim ntawm cov tuag- uas txiav txim siab ntawm phab ntsa vaj huam sib luag thickness, ntoo khaub lig-sectional profile, thiab cov qauv sab hauv- ua qhov tseem ceeb hauv kev ua kom zoo ntawm cov khoom molded.
Cov vaj huam sib luag extruded tshiab tau txias sai heev thiab teeb tsa siv dej - lub tank txias lossis cua - cua txias system; ib txhij, ib tug traction mechanism tswj cov kab ceev kom ntseeg tau tias seem stability. Thaum teeb tsa, cov phab ntsa vaj huam sib luag tau txais kev kho deg tiav -xws li thermal hloov luam ntawv, lamination, lossis tshuaj tsuag txheej - kom ua tiav cov txiaj ntsig zoo nkauj zoo li ntoo grain, pob zeb textures, lossis xim xim. Thaum kawg, cov panels raug txiav, tshuaj xyuas zoo, thiab ntim khoom ua ntej tso tawm raws li cov khoom tiav.
