Hollow Board (Kuj hu ua Hollow Grid Board lossis Wholesel Board) yog lub teeb ci, noo {{{{1} {{1} {{1} {{1} {{1} {1} {{1} {{1} {{1} {{1} {{1} {{1} { Cov txheej txheem ntau lawm tau ua tiav ntau dua ntau xyoo los tsim cov khoom tsim tau thiab ruaj khov tsim. Nws feem ntau suav nrog cov kauj ruam tseem ceeb xws li cov khoom siv cov khoom siv tau, kev sib xyaw, moulding, sib tov, txiav, thiab post {{4} ua.
RAW KHOOM npaj thiab sib tov
Thawj cov ntaub ntawv raw rau lub rooj sib luag Hollow yog polypropylene (pp) lossis polyethylene (HDPE). Cov tshuaj ntxiv xws li UV Stabilizers, nplaim taws retardants, thiab masterbatches yuav raug ntxiv raws li xav tau los txhim kho kev ua tau zoo. Cov khoom siv raw yog qhov ntsuas kom ntseeg tau tias lawv tsis muaj kev sib xyaw thiab cov khoom siv ceev}} Ceev ceev cov khoom siv thiab xim ceev.
Txiav tawm moulding
Cov khoom siv raw yog rhuab thiab melted nyob rau hauv ib lub ntxaib {{0} Nyem rau ntawm 180 degree, nyob ntawm cov khoom hom. Cov ntaub ntawv yas molten cov khaub ncaws melt nyob rau hauv Extruder thiab yog tom qab ntawd extruded tuag los ua qauv ntawm ib multi {txheej hollow hollow board qauv. Pwm Tsim Qauv ncaj qha cuam tshuam cov ntawv tuab, Honeycomb qauv, thiab tag nrho lub zog.
Cua txias thiab shaping
Extruded Hollow ntawv qauv qauv ua kom tau nkag mus rau peb - roll calender lossis lub tshuab nqus ntshav rau qhov txias thiab nqus. Lub cua txias cua txias hluav taws xob kev tswj hwm daim ntawv ntsuas kub, ua kom muaj kev ruaj khov Solidification thiab tswj qhov seem ruaj khov. Tus calender tseem hloov kho cov ntawv tiaj tus thiab gloss tau raws li cov kev thov tshwj xeeb.
Kev txiav thiab tshaj tawm - kev ua
Daim duab ua luam daim ntawv txiav tawm mus rau qhov loj me uas siv cov cutter, thiab cov npoo tuaj yeem txiav rau kev ua kom zoo nkauj. Qee cov nplooj ntawv hollow yuav tsum tau tshaj tawm - kev ua haujlwm xws li luam ntawv, kev lamination, lossis xuas nrig ntaus los txhim kho lawv cov haujlwm lossis ua haujlwm zoo.
Tus yuam sij rau lub hollow seet ntau lawm txheej txheem nyob rau hauv raw khoom piv, muab kev kub thiab txias thiab txias thiab txias thiab hloov kho qhov tseeb. Cov xwm txheej no ncaj qha cuam tshuam cov ntawv muaj zog, huab cua Kuj, thiab lub neej pabcuam. Nrog thev naus laus zis nce zuj zus, niaj hnub hollow daim ntawv ntau lawm yog txav mus rau ntau dua kev ua lag luam xav tau lub teeb ci thiab cov ntaub ntawv muaj zog.
