Iinkqubo zeMveliso yeeFilimu zePVC: I-Extrusion kunye neCalender

Iifilimu zePVC zisetyenziswa ngokubanzi ekupakishweni kokutya, ezolimo, kunye nokupakishwa kwamashishini. I-Extrusion kunye ne-calendering ziinkqubo ezimbini eziphambili zemveliso.

I-Extrusion: Ukusebenza kakuhle kuhlangabezana neendleko ze-Advantage

Amaziko e-Extrusion ajikeleze i-screw extruder. Isixhobo esibambeneyo siyonga indawo kwaye kulula ukusifaka kunye nokulungiswa kweempazamo. Emva kokuxuba izinto eziphathekayo ngokwefomula, zingena ngokukhawuleza kwi-extruder. Njengoko i-screw ijikeleza ngesantya esiphezulu, izinto eziphathekayo zenziwe ngeplastiki ngokukhawuleza ngamandla okucheba kunye nokufudumeza okuchanekileyo. Emva koko, zikhutshelwa kwimilo yefilimu yokuqala ngentloko yokufa eyilwe ngononophelo, kwaye ekugqibeleni zipholile kwaye zibunjwe ngama-roller okupholisa kunye neringi yomoya. Inkqubo iyaqhubeka nokusebenza okuphezulu.

Ubukhulu befilimu buqala kwi-0.01mm ukuya kwi-2mm, buhambelana neemfuno ezahlukeneyo. Nangona i-uniform encinci kubukhulu kuneefilimu ze-calendered, isebenza kwiimveliso ezineemfuno ezichanekileyo ezisezantsi. Ukusebenzisa imathiriyeli esetyenzisiweyo kunciphisa iindleko. Ngotyalo-mali oluphantsi lwezixhobo kunye nokusetyenziswa kwamandla, inika inzuzo enkulu. Ke, iifilimu ze-extrusion zisetyenziswa ikakhulu kwezolimo kunye nokupakishwa kwemizi-mveliso, njengeefilimu ze-greenhouse kunye neefilim zokwelula imithwalo.

ICalender: Isithethantonye kunye noMgangatho oPhezulu

Izixhobo zendlela ye-calendering zenziwe ngee-roller ezininzi ezichanekileyo zokufudumala. Eziqhelekileyo ziyi-three-roll, i-four-roll okanye i-five-roll calenders, kwaye i-roller kufuneka ilungiswe ngokucophelela ukuze kuqinisekiswe ukuchaneka komsebenzi. Izinto eziphathekayo ziqale zixutywe nge-high-speed kneader, emva koko zifake i-mixer yangaphakathi kwi-plasticization enzulu, kwaye emva kokucinezelwa kumaphepha nge-mill evulekile, bangena kwi-calender. Ngaphakathi kwekhalenda, amashidi akhutshwe ngokuchanekileyo kwaye anwenwe ngama-roller okufudumala amaninzi. Ngokulawula ubushushu kunye nesithuba se-roller, ukutenxa kobunzima befilimu kunokuzinziswa ngaphakathi kwe-± 0.005mm, kwaye ukucaca komphezulu kuphezulu.

Iifilimu ze-PVC zeCalender zinobukhulu obufanayo, iipropathi zoomatshini ezilungeleleneyo, iipropathi ezibalaseleyo zamehlo, kunye nokubonakala okuphezulu. Kwipakethe yokutya, babonisa ukutya kwaye baqinisekise ukhuseleko. Kwiimpahla zemihla ngemihla eziphezulu kunye nokupakishwa kwemveliso ye-elektroniki, umgangatho wabo ophezulu ubenza ukuba babe lolona khetho luphezulu.

Kwimveliso yeefilimu ze-PVC, nokuba yinkqubo ye-calendering okanye inkqubo ye-extrusion,PVC izinzisidlala indima ebalulekileyo.TopJoy Chemical'si-liquid barium-zinckwayei-calcium-zinc stabilizersthintela ukuthotywa kwePVC kumaqondo aphezulu, qinisekisa uzinzo lwezinto, ukusasaza kakuhle kwinkqubo yePVC, kunye nokunyusa ukusebenza kakuhle kwemveliso. Wamkelekile ukuba uqhagamshelane nathi nangaliphi na ixesha kwaye sijonge phambili kwintsebenziswano ngakumbi nawe!
