Mus rau mais ntxiv hauv kev nkag siab SPC flooring, cia peb saib seb nws tau ua li cas.SPC yog tsim los ntawm 6 cov txheej txheem hauv qab no.
Sib tov
Txhawm rau pib, kev sib xyaw ntawm cov khoom siv raw yog muab tso rau hauv lub tshuab sib tov.Ib zaug sab hauv, cov ntaub ntawv raw yog rhuab mus rau 125 - 130 degrees Celsius thiaj li yuav tshem tawm cov dej vapor hauv cov khoom.Tom qab ua tiav, cov khoom siv txias txias rau hauv lub tshuab sib xyaw kom tsis txhob muaj qhov tshwm sim ntawm plasticization thaum ntxov los yog ua haujlwm pab cuam decomposition.
Extrusion
Tsiv los ntawm lub tshuab sib tov, cov khoom siv raw ces mus los ntawm txheej txheem extrusion.Ntawm no, kev tswj qhov kub thiab txias yog qhov tseem ceeb hauv kev txiav txim rau cov khoom siv yas kom raug.Cov khoom siv tau khiav mus txog tsib cheeb tsam, nrog rau thawj ob yog qhov kub tshaj plaws (nyob ib ncig ntawm 200 degrees Celsius) thiab maj mam poob mus thoob plaws hauv peb cheeb tsam ntxiv.
Daim ntawv qhia hnub
Thaum cov khoom siv tag nrho plasticized rau hauv pwm, nws yog lub sijhawm rau cov khoom siv los pib txheej txheem hu ua calendering.Ntawm no, ib tug series ntawm rhuab rollers yog siv los muab cov pwm rau hauv ib daim ntawv txuas ntxiv.Los ntawm kev tswj cov yob, qhov dav thiab tuab ntawm daim ntawv tuaj yeem tswj tau nrog qhov tseeb thiab qhov sib xws.Thaum lub thickness xav tau mus txog, nws yog embossed nyob rau hauv tshav kub thiab siab.Engraved rollers siv cov qauv tsim rau ntawm lub ntsej muag ntawm cov khoom uas tuaj yeem yog lub teeb "zuam" lossis "sib sib zog nqus" emboss.Thaum qhov kev ntxhib los mos yog siv, kos thiab scuff Top Coat yuav raug siv thiab xa mus rau lub tub rau khoom.
Lub tub rau khoom
Lub tshuab kos duab, siv nrog ntau zaus tswj, txuas nrog lub cev muaj zog ncaj qha, uas yog qhov zoo tshaj plaws rau cov kab ntau lawm ceev thiab siv los xa cov khoom mus rau lub tshuab txiav.
Cutter
Ntawm no, cov khoom siv yog crosscut kom ua tau raws li tus qauv qhia tseeb.Lub cutter yog signaled los ntawm ib tug rhiab thiab yog photoelectric hloov mus kom huv si thiab sib npaug txiav.
Automatic Plate-Lifting Tshuab
Thaum cov khoom raug txiav lawm, lub tshuab nqa lub phaj tsis siv neeg yuav nqa thiab ntim cov khoom kawg rau hauv qhov chaw ntim khoom rau tuaj tos.
