SPC stairnose feem ntau suav nrog cov txheej txheem ntau txheej xws li txheej txheej khoom siv, txheej txheej zoo nkauj, thiab txheej hnav-tiv taus.Lub hauv paus txheej txheem siv cov hmoov pob zeb ntuj (calcium carbonate hmoov) thiab polymer resin (polyvinyl chloride) ua cov ntaub ntawv tseem ceeb uas yuav tsum tau extruded los ntawm cov txheej txheem thermal fusion.
SPC stairnose yog ib yam khoom uas extrudes PVC puag khoom los ntawm extruder ua ke nrog T-zoo li tus tuag, thiab siv peb-yob los yog plaub-yob calender cais PVC hnav-resistant txheej, PVC xim zaj duab xis thiab PVC puag khoom, thiab tshav kub, laminate thiab emboss cov khoom nyob rau hauv ib lub sij hawm., Cov txheej txheem yog yooj yim, haum yog ua tiav los ntawm tshav kub, tsis muaj kua nplaum yuav tsum tau.
SPC stairnose txheej txheem txheej txheem:
1. Kev pub mis: PVC resin hmoov, calcium hmoov, plasticizer, stabilizer thiab lwm yam raw khoom yog pub nyob rau hauv kev faib ua feem los ntawm lub metering system ntawm qhov chaw nres nkoj pub, thiab kev pub mis yog phau ntawv los yog lub tshuab nqus tsev noj mov.
2. Kev sib xyaw: kev ntsuas tsis siv neeg raws li qhov sib piv ntawm cov khoom siv raw, cov khoom siv raw los ntawm kev ntsuas qhov system nkag mus rau qhov siab thiab qis ceev tov khoom → kev kub ceev sib tov rau kev sib tov kub (kub sib tov cua sov: 125 ° C, muaj nuj nqi yog sib tov. Txhua yam ntawm cov ntaub ntawv sib npaug thiab tshem tawm cov dej noo hauv cov ntaub ntawv ) → nkag mus rau qhov sib xyaw txias (txias cov khoom kom tiv thaiv kev sib tsoo thiab tawg, qhov sib xyaw txias txias: 55 ° C.) → sib tov cov khoom sib xws los ntawm kev ua kom txias.
3. Extrusion molding: Xa cov khoom sib xyaw ua ke rau hauv lub extruder, thiab siv nws qhov kub thiab txias siab rau extrude los ntawm substrate pwm.Cov txheej txheem extrusion yuav siv sijhawm li 2 feeb, qhov kub thiab txias yog li 180-220 ° C, thiab cov roj hloov hluav taws xob yog siv.Cov cuab yeej ua kom sov.
4. Zaj duab xis-npog thiab calendering: Extruded hauv qab daim ntawv PVC zaj duab xis yog nias rau hauv ib daim ntawv nrog plaub-yob los yog tsib-yob calenders, hnav-resistant txheej thiab PVC xim zaj duab xis.Nws txais ib zaug cua sov, lamination thiab embossing.Cov txheej txheem yog yooj yim thiab yooj yim rau paste.Nws yog ua tiav los ntawm tshav kub, siv lub tshav kub hloov pauv roj kev ntsuas kub tswj, siv cov roj hloov hluav taws xob ua hluav taws xob hloov nruab nrab kom tswj tau qhov kub ntawm qhov kub ntawm 140 ° C.
5. Txiav thiab txiav: txiav los ntawm lub tshuab txiav ntawm cov kab sib dhos.
6. UV rau cov menyuam txheej: Cov menyuam lub tsho UV dej-raws li cov xim pleev xim rau ntawm cov pob zeb-yas pem teb, cua sov thiab kho kom tau txais SPC pob zeb-yas pem teb semi-tiav khoom, UV cov menyuam txheej kub: 80-120 ° C;Qhov kub thiab txias: 10 ° C
4. Slitting thiab slotting + ntim: slitting → slotting, trimming, chamfering → soj ntsuam → ntim.
