I-SPC stairnose ngokubanzi ibandakanya ulwakhiwo lwe-multi-layer olufana nesiseko semathiriyeli, umaleko wokuhombisa, kunye ne-resistant-resistant layer.Isiseko sezinto eziphathekayo sisebenzisa umgubo wamatye wendalo (i-calcium carbonate powder) kunye ne-polymer resin (i-polyvinyl chloride) njengezona zinto ziphambili eziza kukhutshwa ngenkqubo yokuxuba i-thermal.
I-SPC stairnose yimveliso ekhupha isiseko se-PVC nge-extruder edityaniswe ne-T-shaped die, kwaye isebenzisa i-calender ye-roll-roll okanye i-4-roll-roll ukwahlula i-PVC ekwazi ukumelana nokunxiba, ifilimu ye-PVC yombala kunye nesiseko se-PVC, kunye nobushushu, i-laminate kunye ne-laminate. emboss imveliso ngexesha elinye., Inkqubo ilula, ukulungelelaniswa kugqitywe ngokushisa, akukho glue efunekayo.
Iinkqubo zenkqubo yokuvelisa izinyuko ze-SPC:
1. Ukutya: I-PVC ye-resin powder, i-calcium powder, i-plasticizer, i-stabilizer kunye nezinye izinto eziluhlaza zondliwa ngokulinganayo nge-metering system kwi-port yokutya, kwaye ukutya kusenziwa ngesandla okanye kwi-vacuum feeding.
2. Ukuxuba: ukulinganisa okuzenzekelayo ngokomlinganiselo wezinto ezikrwada, izinto ezisetyenziswayo ngenkqubo yokulinganisa ngenisa umxube wesantya esiphezulu nesisezantsi → isantya esiphezulu somxube wokuxutywa okushushu (iqondo lobushushu bokuxuba: 125 °C, umsebenzi kukuxuba zonke iintlobo zemathiriyeli ngokulinganayo kwaye ukhuphe ukufuma kwimathiriyeli ) → faka ukuxuba okubandayo (zipholisa imathiriyeli ukunqanda ukungqubana nokujika kombala, ubushushu obuxutywayo obubandayo: 55°C.) → xuba imathiriyeli efanayo ngokupholisa.
3. Ukubunjwa kwe-Extrusion: Thumela izinto ezixubeneyo ezixutywe kwi-extruder, kwaye usebenzise ukushisa kwayo okuphezulu kunye noxinzelelo oluphezulu lokunyusa ukukhupha kwi-mold substrate.Inkqubo ye-extrusion ithatha malunga nemizuzu emi-2, iqondo lokushisa li malunga ne-180-220 ° C, kunye neoli yokudlulisa ukushisa isetyenziswa.Isixhobo siyafudumala.
4. Ukugqunywa kwefilimu kunye ne-calendering: Iphepha elisezantsi eligqithisiweyo Ifilimu ye-PVC icinezelwe kwifom edibeneyo kunye ne-four-roll okanye i-five-roll calenders, i-wear-resistant layer kunye nefilimu yombala we-PVC.Yamkela ukufudumeza kwexesha elinye, i-lamination kunye ne-embossing.Inkqubo ilula kwaye kulula ukuyincamathisela.Igqityezelwa ngobushushu, kusetyenziswa isilawuli sobushushu sokujikeleza kweoli yokuhambisa ubushushu, kusetyenziswa ioli yokuhambisa ubushushu njengendlela yokudlulisa ubushushu ukuze kugcinwe ubushushu obucinezelayo obuyi-140°C.
5. Ukusika kunye nokunciphisa: ukusika ngomatshini wokusika kumgca wendibano.
6. Ukugquma kwe-UV ye-roller: I-roller coat ye-UV yepeyinti esekelwe kumanzi phezu komgangatho wamatye-iplastiki, ubushushu kunye nokunyanga ukufumana i-SPC ilitye-plastiki yomgangatho ogqityiweyo wemveliso, ukushisa kwe-UV roller: 80-120 ° C;iqondo lokupholisa: 10°C
4. Ukusika nokukrola + ukupakisha: ukunqunqa → ukunqunqa, ukucheba, ukukrola → ukuhlola → ukupakisha.
