Izongezo ezifanelekileyo ziyafuneka ukuguqula umphezulu wepolymer kunye nomgubo womthi ukuphucula unxibelelwano phakathi komgubo womthi kunye nentlaka.
Isiphumo sokusasazwa komgubo wokhuni kunye nesixa esikhulu sokuzalisa kwi-thermoplastic etyhidiweyo ihlwempuzekile, nto leyo eyenza ukunyibilika kwe-fluidity ibe nzima kunye nenkqubo ye-extrusion nzima.I-arhente yonyango yomphezulu inokongezwa ukuze kuphuculwe i-fluidity ukuququzelela inkqubo ye-extrusion.
I-matrix yeplastiki nayo ifuna ukongeza izongezo ezahlukeneyo ukuphucula ukuqhubekeka kwayo kunye nokusetyenziswa kwemveliso yayo.
Isakhiwo somgubo womthi sikhululekile, kwaye akulula ukondla i-screw extruder.Ngokukodwa, into ethi "ibhulorho" kunye "nepali yokubamba" ihlala isenzeka xa umgubo wokhuni unamanzi amaninzi.
Ukungazinzi kokutya kuya kubangela ukuguquguquka kwe-extrusion, okukhokelela ekunciphiseni umgangatho we-extrusion kunye nemveliso.Ukuphazamiseka kokutya kuya kwandisa ixesha lokuhlala kwezinto kwi-barrel, okuya kukhokelela ekutshisweni kunye nokuguqulwa kombala wezinto eziphathekayo kunye nokuchaphazela umgangatho wangaphakathi kunye nokubonakala kweemveliso.
Isixhobo sokutya esinyanzelweyo kunye nemowudi efanelekileyo yokuhambisa yamkelwa ukuqinisekisa ukuzinza kwe-extrusion.
Ukukhupha ngexesha lokucubungula
I-molecule encinci eguquguqukayo kunye namanzi aqulethwe kumgubo wokhuni kulula kakhulu ukuzisa iziphene kwiimveliso, kwaye ukunyangwa kwangaphambili akukwazi ukuwasusa ngokupheleleyo.Ngoko ke, ingqwalasela engakumbi kufuneka ihlawulwe kuyilo lwenkqubo yokukhupha yokhuni lweplastiki edibeneyo ye-extruder ngaphezu kwe-extruder yeplastiki eqhelekileyo.Ukuba kuyimfuneko, ukukhutshwa kwamanqanaba amaninzi kunokuqhutywa.
Ubukhulu becala, ngcono umphumo wokukhupha, ungcono umgangatho weemveliso ezigqithisiweyo.
