SPC stairnose inowanzo sanganisira yakawanda-layer chimiro senge base yezvinyorwa layer, yekushongedza layer, uye inopfeka-inodzivirira layer.Iyo base base material layer inoshandisa yakasikwa dombo poda (calcium carbonate poda) uye polymer resin (polyvinyl chloride) seyakanyanya mbishi zvinhu kuti zviburitswe kuburikidza neanopisa fusion maitiro.
SPC stairnose chigadzirwa chinoburitsa PVC base material ne extruder yakasanganiswa neT-shaped die, uye inoshandisa matatu-roll kana mana-roll calender kupatsanura PVC kupfeka-resistant layer, PVC color film uye PVC base material, uye kupisa, laminate uye. emboss chigadzirwa panguva imwe chete., Iyo nzira iri nyore, iyo yakakodzera inopedzwa nekupisa, hapana glue inodiwa.
SPC stairnose kugadzira maitiro maitiro:
1. Kudyisa: PVC resin powder, calcium powder, plasticizer, stabilizer nezvimwe zvinhu zvakasvibirira zvinodyiswa zvakaenzana kuburikidza ne metering system pachiteshi chekudya, uye kudyisa ibhuku kana kuti vacuum feeding.
2. Kusanganisa: otomatiki metering zvinoenderana nereshiyo yezvigadzirwa, iyo mbishi kuburikidza neiyo metering system inopinda yakakwirira uye yakaderera yekumhanyisa musanganisi → yakakwira yekumhanyisa musanganisi wekusanganisa kupisa (kupisa kusanganisa kupisa tembiricha: 125 °C, basa nderekusanganisa. marudzi ese ezvishandiso zvakaenzana uye bvisa mwando muzvishandiso
3. Extrusion molding: Tumira iyo yakasanganiswa mbishi zvinhu mu extruder, uye shandisa iyo yakanyanya tembiricha uye yakakwirira yekumanikidza mamiriro ekunze kuburikidza ne substrate mold.Iyo extrusion process inotora anenge 2 maminetsi, tembiricha inenge 180-220 ° C, uye kupisa kupisa mafuta kunoshandiswa.Mudziyo unopisa.
4. Firimu-kufukidza uye calendering: Yakawedzera pasi pepa PVC firimu inotsikirirwa mufomu yakabatanidzwa ine mana-roll kana mashanu-roll calenders, kupfeka-resistant layer uye PVC color film.Iyo inotora-imwe-nguva yekudziya, lamination uye embossing.Nzira yacho iri nyore uye iri nyore kuisa.Inopedzwa nekupisa, uchishandisa kupisa kwemafuta ekutenderera kutenderera tembiricha controller, uchishandisa kupisa kupisa mafuta senge yekutamisa svikiro kuchengetedza kupisa kunopisa kupisa kwe140 ° C.
5. Kucheka nekucheka: kucheka nemuchina wekucheka pamutsetse wegungano.
6. UV roller coating: Roller jasi UV mvura-based pendi pamusoro pedombo-plastiki pasi, kupisa uye kurapa kuwana SPC ibwe-plastiki pasi semi-yakapedza chigadzirwa, UV roller coating tembiricha: 80-120 ° C;kutonhora tembiricha: 10°C
4. Kucheka nekutsemura + kurongedza: kutsemura → kutsemura, kucheka, kukwezva → kuongorora → kurongedza.
