Extrusion of Plastics - Mfundo Yogwira Ntchito ndi Njira Zopangira
Extrusion ndi njira yopangira zinthu zambiri.Zinthu zapulasitiki zimasungunuka ndikugwiritsa ntchito kutentha ndikutuluka kudzera mukufa kukhala mawonekedwe omwe mukufuna.Zomangira zozungulira za cylindrical zimayikidwa mkati mwa mbiya zomwe zimatulutsa zinthu zapulasitiki zosungunuka kudzera mukufa.Zinthu zowonjezera zimatengera ...Werengani zambiri -
Njira Yopanga ya PTFE
Tetrafluoroethylene inakonzedwa koyamba mu 1933. Zogulitsa zamakono zamakono zimachokera ku fluorspar, sulfuric acid ndi chloroform.Basic Kupanga Njira ya PTFE Polima: Kupanga kwa PTFE Polima/Utomoni kwenikweni ikuchitika mu magawo awiri.Choyamba, TFE Monomer nthawi zambiri imapangidwa ...Werengani zambiri -
Kutulutsa kwa ma polima
Extrusion ndi njira yopangira zinthu zazitali zokhazikika (ndodo, mapepala, mapaipi, mafilimu, zokutira waya) kukakamiza kufewetsa polima kudzera pakufa ndi kutsegula.Zinthu za polima zokhala ngati ma pellets zimadyetsedwa ku extruder kudzera pa hopper.Zinthu zake ndi ...Werengani zambiri -
