Ngaphambi kwenqubo eyinhloko ye-extrusion, okuphakelayo kwe-polymeric okugciniwe kuxubene nezithasiselo ezahlukahlukene njengeziqinisi (zokushisa, ukuzinza kwe-oxidative, ukuzinza kwe-UV, njll.), izingulube zombala, izinto ezibuyisela amalangabi, izigcwalisi, okothambisa, okokuqinisa, njll. izinga lomkhiqizo kanye nokucutshungulwa.Ukuxuba i-polymer nezithasiselo nakho kusiza ukufeza ukucaciswa kwephrofayili yesakhiwo esiqondiwe.
Kwezinye izinhlelo ze-resin, inqubo eyengeziwe yokomisa ukuvimbela ukuwohloka kwe-polymer ngenxa yomswakama ngokuvamile isetshenziswa.Ngakolunye uhlangothi, kulezo ngokuvamile ezingadingi ukomiswa ngaphambi kokusetshenziswa, kungase kudingeke zomiswe ikakhulukazi lapho zigcinwe emakamelweni abandayo futhi kungazelelwe zibekwe endaweni efudumele ngaleyo ndlela kuqalise ukujiya komswakama phezu kwempahla.
Ngemuva kokuthi i-polymer kanye nezithasiselo kuxutshwe futhi zomiswa, ingxube ifakwa ku-hopper yokuphakelayo nangomphimbo ophuma ngaphandle.
Inkinga eyodwa evamile lapho uphatha izinto eziqinile njenge-polymer powder ukugeleza kwayo.Kwezinye izimo, ibhuloho lempahla ngaphakathi kwe-hopper kungenzeka.Ngakho-ke, izinyathelo ezikhethekile ezinjengomjovo wezikhawu we-nitrogen nanoma iyiphi igesi engasebenzi ingasetshenziswa ukuphazamisa noma iyiphi i-polymer enqwabelene phezu kwe-feed hopper ngaleyo ndlela kuqinisekiswe ukugeleza okuhle kwento.
Okubalulekile kugeleza phansi kusikhala se-annular phakathi kwesikulufu kanye nomgqomo.Impahla iphinde iboshwe isiteshi sesikulufa.Njengoba isikulufu sizungeza, i-polymer idluliselwa phambili, futhi amandla aphikisanayo asebenza kuso.
Imiphongolo ivamise ukushiselwa ngephrofayili yokushisa ekhuphuka kancane kancane.Njengoba ingxube ye-polymer ihamba isuka endaweni yokuphakelayo ikhuphukele endaweni yemitha, amandla okungqubuzana nokushisisa komgqomo kubangela ukuthi impahla yenziwe ipulasitiki, ixutshwe ngendlela efanayo, futhi ihlanganiswe ndawonye.
Okokugcina, njengoba ukuncibilika kusondela ekupheleni kwe-extruder, kuqala kudlula iphakethe lesikrini.Iphekhi yesikrini isetshenziselwa ukuhlunga noma yiziphi izinto zangaphandle ekuncibilikeni kwe-thermoplastic.Iphinde ivikele imbobo ye-die plate ukuthi ingavaleki.Ukuncibilika bese kuphoqeleka ukuthi kuphume idayizi ukuze kutholwe umumo wokufa.Ipholiswa ngokushesha futhi ikhishwe ku-extruder ngesivinini esingaguquki.
Ezinye izinqubo ezifana nokwelapha ilangabi, ukuphrinta, ukusika, ukuthungatha, ukuqeda iphunga, njll. kungenziwa ngemva kokupholisa.I-extrudate izobe isihlolwa futhi iqhubeke nokupakishwa nokuthunyelwa uma yonke imininingwane yomkhiqizo ihlangatshezwana nayo.
