Izinto Ezijwayelekile Zokukhipha
Kusetshenziswa izinto ezahlukahlukene enqubweni ye-extrusion. Lapha singathatha isibonelo senqubo ye-PVC extrusion. Ezinye izinto zokwakha i-polyethylene, i-acetal, inayiloni, i-acrylic, i-polypropylene, i-polystyrene, i-polycarbonate, ne-acrylonitrile. Lezi yizinto eziyinhloko ezisetshenziselwa inqubo ye-extrusion. Nokho, inqubo ayigcini kulezi zinto zokwakha.
Ulwazi oluyisisekelo lweinqubo ye-plastic extrusion
Inqubo ye-plastic extrusion izoqala ngokushintsha i-resin eluhlaza. Okokuqala, yibeke ku-hopper ye-extruder. Lapho i-resin ingenazo izithasiselo zezinhlelo ezithile zokusebenza, izithasiselo zengezwa ku-hopper. Ngemuva kokubekwa, i-resin idliwe kusuka echwebeni lokuphakelayo le-hopper, bese ingena emgqonyeni we-extruder. Kukhona isikulufu esizungezayo emgqonyeni. Lokhu kuzophakela i-resin, ezohamba ngaphakathi komgqomo omude.
Phakathi nale nqubo, i-resin ivezwa emazingeni okushisa aphezulu. Amazinga okushisa aphezulu kakhulu angancibilikisa izinto. Kuye ngezinga lokushisa lomphongolo kanye nohlobo lwe-thermoplastic, izinga lokushisa lingahluka kusuka ku-400 kuya ku-530 degrees Fahrenheit. Ukwengeza, ama-extruder amaningi anomphongolo okhuphula ukushisa ukusuka ekulayisheni kuye ekudleni kuye ekuncibilikeni. Yonke inqubo inciphisa ingozi yokuwohloka kwepulasitiki.
Ipulasitiki yayizoncibilika futhi ifinyelele ekupheleni komgqomo, lapho yayizocindezelwa khona eshubhu lokuphakelayo ngesisefo futhi ekugcineni ife. Phakathi nenqubo yokukhishwa, izikrini zizosetshenziselwa ukususa ukungcola epulasitiki encibilikisiwe. Inombolo yezikrini, ukuqina kwezikrini nezinye izici zilawulwa ukuze kuqinisekiswe ukuncibilika okufanayo. Ukwengeza, i-back pressure isiza ekuncibilikeni okufanayo.
Lapho into encibilikisiwe ifinyelela epayipini lokuphakelayo, izofakwa emgodini wesikhunta. Ekugcineni, liyaphola futhi libe lukhuni ukwenza umkhiqizo wokugcina. Ipulasitiki esanda kwenziwa inebhavu lamanzi elivaliwe ukuze kusheshiswe inqubo yokupholisa. Kodwa-ke, ngesikhathi sokukhishwa kweshidi, ukugeza kwamanzi kuzothathelwa indawo ngama-rolls abandayo.
Izinyathelo eziyinhloko zeinqubo yokukhipha ipayipi lepulasitiki
Njengoba kushiwo ngaphambili, inqubo ye-plastic extrusion ikhiqiza imikhiqizo eminingi ehlukahlukene kusukela ezintweni zokwakha kuya ezingxenyeni zezimboni, izivalo zikagesi, amafreyimu amafasitela, i-edging, i-weatherstripping kanye nothango. Kodwa-ke, inqubo yokwenza yonke le mikhiqizo ehlukene izofana nokuhluka okuncane. Kunezindlela eziningana zokungena kwamapayipi epulasitiki.
Mukuncibilika kwe-aterial
Izinto ezingavuthiwe ezihlanganisa ama-granules, impushana noma ama-granules azolayishwa ku-hopper. Ngemva kwalokho, impahla ifakwa ekamelweni elishisayo elibizwa ngokuthi i-extruder. Izinto ziyancibilika njengoba zidlula ku-extruder. Ama-extruder anamabhawodi ajikayo amabili noma owodwa.
Ukuhlunga okubalulekile
Ngemva kokuba impahla isincibilikile, inqubo yokuhlunga izoqala. Izinto ezincibilikisiwe zizogeleza zisuka ku-hopper zidlule emphinjeni ziye kusikulufa esijikelezayo esigijima ngaphakathi kwe-extruder. Isikulufu esijikelezayo sisebenza emgqonyeni ovundlile lapho into encibilikisiwe izohlungwa ukuze kutholwe ukufana okufanayo.
Ukunquma Ubukhulu Bezinto Ezincibilikisiwe
Izakhiwo zezinto zepulasitiki ziyahlukahluka kuye ngezinto zokusetshenziswa ezisetshenziswa kule nqubo. Nokho, zonke izinto zokusetshenziswa ziphathwa ukushisa. Lezi zinto zizovezwa ekushiseni okukhulu emazingeni okushisa athile. Amazinga okushisa azohluka ngokuya ngezinto ezingavuthiwe. Ngesikhathi sokuphothulwa kwenqubo, ipulasitiki encibilikisiwe izophushwa ngembobo ebizwa ngokuthi isikhunta. Ibumba impahla ibe umkhiqizo wokugcina.
Post processing
Kulesi sinyathelo, ukusikwa kwefa kwephrofayili kuzoklanywa ukuthi kube nokugeleza okulinganayo futhi okubushelelezi kusuka kuphrofayili ye-cylindrical ye-extruder kuya kumumo wokugcina wephrofayili. Kuhle ukusho ukuthi ukuze uthole imikhiqizo enokwethenjelwa nekhwalithi ephezulu, ukuhambisana kokugeleza kwepulasitiki kubaluleke kakhulu.
Mukupholisa kwe-aterial
Ipulasitiki izokhishwa ekubunjweni futhi idluliselwe ngebhande ukuze iphole. Lolu hlobo lwebhande lubizwa ngokuthi ibhande lokuthutha. Ngemva kwalesi sinyathelo, umkhiqizo wokugcina upholiswa ngamanzi noma ngomoya. Kuhle ukusho ukuthi inqubo izofana nokubumba umjovo. Kodwa umehluko ukuthi ipulasitiki encibilikisiwe incinywa yisikhunta. Kodwa ekubumbeni umjovo, inqubo yenzeka ngokusebenzisa isikhunta.
