Polima Extrusion Chiyambi

Plastics extrusion ndi njira yopangira zinthu zambiri momwe pulasitiki yaiwisi imasungunuka ndikupangidwa kukhala mbiri yopitilira ...

Extrusion chimagwiritsidwa ntchito m'mafakitale osiyanasiyana.Mukuyesera uku, tikufufuza pulasitiki extrusion ndi screw extruder.Extruder zotere ndizofala kwambiri m'makampani apulasitiki.

Kodi Chimachitika N'chiyani mu Extruder?

Zowononga mu extruder zimazungulira ndikupanga kukakamiza kokwanira kukakamiza zinthu kuti zidutse ndikutulutsa zinthu zokhala ndi geometry yomwe mukufuna.

Zigawo za Extruder

Pali zigawo zisanu zazikulu mu extruder: screw, extruder drive, mbiya, feed hopper, ndi kufa.Mtima wa extruder ndi helical screw yomwe imathandizira mayendedwe, kutentha, kusungunuka, ndi kusakaniza pulasitiki.Extruder drive ndi mota yamagetsi yomwe imapereka mphamvu yozungulira wononga.Kukhazikika ndi khalidwe la mankhwala zimadalira kwambiri mapangidwe wononga.Chophimbacho chimayikidwa mu mbiya ya extruder yomwe imapereka mphamvu zowotcha ndi kuziziritsa.Zopangira zimaperekedwa kuchokera ku chakudya chophatikizira chomwe chimalumikizidwa ndi mbiya ndi mmero wa chakudya.Chodulira chakudya chimapangidwa kuti chizikhala ndi ma pellets apulasitiki ndikuwonetsetsa kuti ma pellets akuyenda mumgolo.Imfayo ili pamtunda wa extruder ndipo imatsimikizira mawonekedwe a chinthucho.Pali mitundu ingapo yamafa, kuphatikiza ma chubu amafa, filimu yosalala imafa, ndi filimu yowombedwa.Mu labu iyi, timagwiritsa ntchito ma chubu a annular.Dziwani kuti kukula ndi mawonekedwe a mankhwala extruded si ndendende kukula ndi mawonekedwe a kufa chifukwa kujambula pansi, kuzirala, kutupa, ndi kumasuka wa polima extruded.

Extrusion Lines

Kuphatikiza pa extruder, njira yotulutsira imafuna zida zam'mwamba ndi zapansi.Zida zazikulu za chingwe cha extrusion ndi kugwira ntchito kwa utomoni, makina owumitsa, chodulira, chojambula pambuyo kapena chowongolera, chipangizo chozizirira, chipangizo chonyamulira, ndi chodula kapena chocheka.Mzere wa extrusion mu labu yathu umaphatikizapo extruder, take-off roller, ndi madzi ozizira.
