Xa kuthelekiswa nezinye iimveliso zeplastiki ezikhutshiweyo, i-SUZHOU SUPXTECH imveliso yeplastiki ye-PVC enogwebu ephantsi ayifuni kuphela iplastiki elungileyo phantsi koxinzelelo oluthile lokunyibilika, kodwa ineemfuno zobugcisa ezihambelanayo zobungakanani, ubungakanani kunye nokufana kwemingxuma yogwebu, kunye ubukhulu, ubulukhuni, ukuqaqamba kunye nokuphela kolusu.Umgangatho womzimba ogwebu amagwebu awuhambelani kuphela nefomula kunye nezinto ezikrwada, kodwa uchaphazeleka ngokuthe ngqo kwaye uthintelwe kukusebenza kwe-chear ye-extruder screw, uxinzelelo lokunyibilika, ubushushu, isantya sokukhupha (i-traction), i-gap yomlomo wokubumba, i-gap yokubumba, ukupholisa. ubushushu bamanzi kunye nezinye izinto.Ke ngoko, xa kuthelekiswa nezinye iimveliso zeplastiki ezikhutshiweyo, iimveliso zeplastiki ezinogwebu lolusu zinobunzima bobugcisa obuthile, ukusuka kwindlela yokusebenza kunye nethiyori kukho iingxaki ezininzi ezingasonjululwanga ezifanele ukufundwa nokusombulula iingcali zeshishini.
I-1, i-PVC yeplastiki yokuvelisa iteknoloji yephepha leplastiki kunye neempawu
Ubunzima bobugcisa bokuvelisa iimveliso zeplastiki zePVC ezinogwebu lugwebu.I-Foaming sisiphumo sokunyuka kunye nokwandiswa kwe-viscosity ye-melt, uxinzelelo lwegesi oluveliswa yi-arhente ekhupha amagwebu kunye noxinzelelo lwe-atmospheric.
Inkqubo yogwebu ngokubanzi ihamba ngokwamanqanaba amathathu:
(1) Irhasi enogwebu inyibilika kumxube weplastiki oyiyunifomu inyibilika kwiqondo lobushushu elithile kunye noxinzelelo kwi-extruder kwaye ifikelele kwimo yokuhluza ukwenza i-bubble core;
(2) I-melt ikhutshwe kwi-die, kunye nokukhululwa koxinzelelo, i-nucleates yegesi enyibilikileyo ene-supersaturated, iyanda kwaye iyancipha, yenze imingxunya ye-bubble efanayo kunye ne-dense bubble kwi-gap ye-formwork;
(3) Ngaphantsi kwempembelelo yokupholisa yesixhobo sokubumba, iimveliso ezinogwebu ziqiniswa kwaye zenziwe.Umgangatho ogqwesileyo wolusu lwePVC iimveliso zeplastiki zineempawu zemingxuma yeqamza exineneyo, encinci kunye neyunifomu, ukuxinana kunye nobukhulu buhlangabezana neemfuno, inkangeleko egudileyo, ubulukhuni obuphezulu kunye nokuqaqamba.
2, ulusu amagwebu PVC ibhodi yeplastiki imiba umgangatho
Ezona zinto ziphambili ekrwada ezichaphazela ngokuthe ngqo umgangatho wesakhiwo se-bubble yeplastiki yi-arhente enogwebu kunye ne-harmonizer egwebu.Izinto eziluhlaza ezifana ne-stabilizer, i-lubricant, i-calcium carbonate kunye nolawulo lwenkqubo ye-extrusion inokukhuthaza kwaye ilungelelanise umgangatho we-foaming ukuya kwinqanaba elithile.Ngenxa yokuba ubushushu beplastiki yokunyibilika kwinkqubo yokukhutshwa kweemveliso ezinogwebu kufuneka bube sezantsi kancinci kunobushushu bokubola kwearhente enogwebu, iqondo elisezantsi le-avareji ye-polymerization ye-PVC resin, iqondo elisezantsi lobushushu obufunekayo ukunyibilika kweplastiki.Ukufumana iimveliso zeplastiki ezinogwebu ngokupheleleyo, i-resin viscosity ayifanele ibe phezulu kakhulu.Kwangaxeshanye, xa kuthelekiswa nezinye iimveliso ugwebu, kuba icandelo umnqamlezo sheet ukwenza banzi, ukusuka intloko extrusion emlonyeni kufa ukuba isasazwe kububanzi malunga 1.3m, ukuze kube lula ukusasazwa kunye nokwandiswa amaqamza. , uxinzelelo lwalo lonke icandelo lomnqamlezo wephepha kufuneka lulungelelaniswe, ukunyibilika kwenyibilika kuphezulu, kwaye ubunzima bemolekyuli yeresin buncinci.Okufana ne-SC-7 okanye i-SC-8 indlela yokunqunyanyiswa kwe-resin ekhululekile ifanelekile ngakumbi.SUZHOU SUPXTECH
