Hanyar samar da stairnose SPC:
1. Ciyarwa: PVC guduro foda, calcium foda, plasticizer, stabilizer da sauran albarkatun kasa ana ciyar da daidai gwargwado ta hanyar metering tsarin a tashar ciyarwa, da kuma ciyarwa ne manual ko vacuum ciyar.
2. Mixing: atomatik metering bisa ga rabo na albarkatun kasa, da albarkatun kasa ta hanyar metering tsarin shigar da high da kuma low gudun mahautsini → babban gudun mahautsini ga zafi hadawa (zafi hadawa dumama zafin jiki: 125 °C, da aikin ne don Mix. kowane nau'in kayan a ko'ina kuma cire danshi a cikin kayan ) → shiga cikin cakuda sanyi ( sanyaya kayan don hana haɓakawa da canza launi, yanayin zafi mai sanyi: 55 ° C.) → haɗa kayan ado ta hanyar sanyaya.
3. Extrusion gyare-gyare: Aika gauraye albarkatun kasa a cikin extruder, da kuma amfani da high zafin jiki da kuma high matsa lamba jihar extrude ta cikin substrate mold.Tsarin extrusion yana ɗaukar kimanin minti 2, zafin jiki yana kusan 180-220 ° C, kuma ana amfani da man canja wurin zafi.Na'urar tana zafi.
4. Film-rufe da calendering: Extruded kasa takardar PVC fim an guga man a cikin wani hadedde nau'i tare da hudu yi ko biyar yi calenders, lalacewa-resistant Layer da PVC launi fim.Yana ɗaukar dumama lokaci ɗaya, lamination da embossing.Tsarin yana da sauƙi kuma mai sauƙi don manna.Ana kammala shi da zafi, ta yin amfani da mai kula da yanayin zafi mai canja wuri mai zafi, ta amfani da mai canja wurin zafi a matsayin matsakaicin zafi don kula da zafin jiki mai zafi na 140 ° C.
5. Yankewa da gyarawa: yankan ta hanyar yankan na'ura akan layin taro.
6. UV abin nadi shafi: Roller gashi UV ruwa-tushen fenti a kan surface na dutse-roba bene, zafi da kuma magani don samun SPC dutse-roba bene Semi kammala samfurin, UV abin nadi shafi zafin jiki: 80-120 ° C;zafin jiki mai sanyaya: 10 ° C
4. Slitting da slotting + marufi: slitting → slotting, trimming, chamfering → dubawa → marufi.
