Kwicandelo lokucubungula iiplastiki, ii-extruders zidlala indima ebalulekileyo ekubumbeni nasekuguquleni ii-polymers zibe ziimveliso ezahlukeneyo. Phakathi kweentlobo ezahlukeneyo zee-extruders, ii-conical twin screw extruders (ii-CTSE) kunye nee-single screw extruders (ii-SSE) zibonakala njengezikhetho eziphambili. Nangona zombini ezi ntlobo zisebenza injongo efanayo yokucubungula ii-polymer, zibonisa iimpawu ezahlukeneyo kunye nobuchule obuzenza zilungele usetyenziso olwahlukeneyo. Esi sikhokelo sibanzi sijonga kwihlabathi lee-CTSEs kunye nee-SSE, sihlola iimpawu zazo ezizodwa, iingenelo, kunye nokusetyenziswa kwazo apho zibalaseleyo khona.
Ii-Extruders zeConical Twin Screw: I-Symphony yokuxuba nokusebenza kakuhle
Ii-extruders ze-Conical twin screw (ii-CTSE) ziyaziwa ngezakhono zazo zokuxuba ezibalaseleyo kunye nokuguquguquka ekusingatheni izicelo ezinzima. Uphawu lwazo oluphambili kuyilo lwe-conical barrel, apho ububanzi be-barrel buyehla kancinci ukuya ekupheleni kokukhupha. Le geometry ikhethekileyo ikhuthaza ukuxubana okunamandla kunye nokudibanisa imixube ye-polymer, izongezo, kunye nezizalisi, okuqinisekisa ukusasazwa okufanayo kwezinto kuyo yonke i-melt.
Iingenelo zeConical Twin Screw Extruders:
Ukuxuba Okuphuculweyo kunye Nokuhlanganiswa Kweemveliso: Ii-CTSE zibalasele ekuveliseni iimveliso ezikumgangatho ophezulu ezineempawu ezihambelanayo kunye nokusebenza, nto leyo ezenza zibe zilungele ukusetyenziswa ezifuna ukuxuba okuphezulu.
Uxinzelelo oluncitshisiweyo lokucheba: Uyilo oluyi-conical lunciphisa uxinzelelo lokucheba kwi-polymer melt, luthintela ukuwohloka kwe-polymer kwaye luqinisekisa umgangatho wemveliso, ngakumbi kwii-polymers ezibuthathaka kucheba.
Uzinzo oluPhucukileyo lokuNcibilika: Ii-CTSE zonyusa uzinzo lokuNcibilika, zinciphisa umngcipheko wokuqhekeka kokuNcibilika kwaye ziqinisekisa inkqubo yokukhutshelwa ngaphandle egudileyo nehambelanayo, ebalulekileyo ekuveliseni iimveliso ezinobukhulu obufanayo kunye neempawu zomphezulu.
Ukuguquguquka kwezicelo ezifuna umgudu: Ii-CTSE ziphatha iikhompawundi ezizaliswe kakhulu, ii-polymers ezibuthathaka, kunye nemixube ye-polymer entsonkothileyo, nto leyo eyenza ukuba zifaneleke kwizicelo ezifuna umgudu ezifana nokufakelwa kwentambo kunye neentambo, iiplastiki zonyango, iiplastiki zeemoto, ukupakisha, kunye nokudibanisa/ukudibanisa izinto.
Ii-Screw Extruders eziSinye: Ukulula kunye nokusebenza kakuhle kweendleko
Ii-single screw extruders (ii-SSE) zimele umsebenzi onzima kwishishini lokucubungula iiplastiki, zibonelela ngesisombululo esilula nesingabizi kakhulu kwiintlobo ngeentlobo zezicelo. Uyilo lwazo lune-screw enye ejikelezayo ngaphakathi kwibharele ye-cylindrical, ihambisa, inyibilikisa, kwaye ibumba i-polymer.
Iingenelo zee-Screw Extruders eziSinye:
Uyilo oluLula kunye nokuSebenza: Ii-SSE zibonelela ngoyilo kunye nokusebenza okulula, okwenza kube lula ukuzigcina kwaye zingabi namonakalo.
Ukusebenziseka kakuhle kweendleko: Ii-SSE ngokubanzi zifikeleleka lula kunee-CTSE, ingakumbi kwizicelo apho ukuxuba okanye ukuphatha izinto ezinzima kungafuneki khona.
Ifanelekile kwiNkqubo eSisiseko: Ii-SSE zibalasele kwimisebenzi yokucubungula i-polymer esisiseko efana nokupelisa, ukuhlanganisa, kunye nokuvelisa iiprofayili ezilula, nto leyo ezenza zifaneleke kwizicelo ezinoxabiso eliphantsi.
Ukukhetha i-Extruder efanelekileyo: Umbandela wokusetyenziswa kunye neemfuno
Isigqibo phakathi kwe-conical twin screw extruder (CTSE) kunye ne-single screw extruder (SSE) sixhomekeke kwiimfuno ezithile zesicelo kunye nokucubungula. Kwizicelo ezifuna ukuxuba okuphezulu, uxinzelelo oluncitshisiweyo lokucheba, uzinzo oluphuculweyo lokunyibilika, kunye nokukwazi ukuphatha izixhobo ezinzima, ii-CTSEs zezona zikhethwayo. Nangona kunjalo, kwimisebenzi yokucubungula esisiseko kunye nezicelo ezinoxabiso oluphantsi, ii-SSE zibonelela ngesisombululo esisebenzayo nesinoqoqosho.
Isiphelo: Ukuhambahamba kwiNdawo ye-Extruder
Ukukhetha phakathi kwe-conical twin screw extruder (CTSE) kunye ne-single screw extruder (SSE) akusosigqibo esifanelekileyo kuzo zonke. Vavanya ngononophelo isicelo esithile, iimfuno zokucubungula, kunye nemida yohlahlo-lwabiwo mali ukuze ubone uhlobo lwe-extruder olufanelekileyo kakhulu. Kwizicelo ezifuna umgudu apho ukuxuba okuphezulu, umgangatho wemveliso, kunye nokukwazi ukuphatha izixhobo ezinzima kubaluleke kakhulu, ii-CTSEs zivela njengokhetho olucacileyo. Nangona kunjalo, kwimisebenzi yokucubungula esisiseko kunye nezicelo ezinobunzima, ii-SSE zibonelela ngesisombululo esisebenzayo nesinoqoqosho. Ngokuqonda amandla kunye nemida yohlobo ngalunye lwe-extruder, iiprosesa zinokwenza izigqibo ezinolwazi eziphucula imisebenzi yazo kwaye zifezekise umgangatho wemveliso oyifunayo.
