Iyo yepurasitiki extrusion process inzira yakatwasuka inosanganisira kunyungudusa pasi resin bead (raw thermostat material), kuisefa uye nekuigadzira kuita chimiro chakapihwa.Iyo screw inotenderera inobatsira mukusundira pasi dhiramu rinopisa kune tembiricha yakapihwa.Purasitiki yakanyungudutswa inopfuudzwa nepadhifi kuti ipe chigadzirwa chekupedzisira chimiro kana chimiro chayo.Kusefa kunopa chigadzirwa chekupedzisira neunifomu kuenderana.Heino kukurumidza kupatsanurwa kwemaitiro ese.
Danho 1:
Maitiro acho anotanga nekuunza zvigadzirwa zvepurasitiki zvakasvibirira senge magranules nemapellets muhopper uye nekudyisa mune extruder.Colorants kana additives anowedzerwa kana mbishi zvinhu zvisina.Siruuru inotenderera inofambisa kufamba kweresin yakasvibira kuburikidza nekamuri inodziya yecylindrical.
Danho rechipiri:
Zvigadzirwa zvehopper zvinozoyerera nepahuro yefeed kusvika kune sizeable spinning screw mukati medhiramu yakachinjika.
Danho rechitatu:
Zvinhu zvakasiyana-siyana zvine maitiro akasiyana, kusanganisira kunyunguduka kwekushisa.Sezvo resin yakasvibirira ichipfuura nemukamuri inopisa, inopisa kune chaiyo yekunyunguduka kwayo, kubva pa400 kusvika ku530 degrees Fahrenheit.Iyo resin yakanyatso kusanganiswa nenguva iyo inosvika kumagumo escuru.
Danho 4:
Resin isati yapfuudzwa nemufa kuti igadzire chimiro chechigadzirwa chekupedzisira, inopfuura nepascreen yakasimbiswa neplate yekutyora.Chidzitiro chinobvisa zvinosvibisa kana kusawirirana kungave kuri mupurasitiki yakanyungudutswa.Iyo resin ikozvino yagadzirira kufa sezvo ichiiswa mugomba rekutonhodza nekuomesa.Mvura yekugezera kana kutonhora rolls inogona kubatsira mukusimbisa kutonhora.
Danho rechishanu:
Iyo yepurasitiki profil extrusion process inofanirwa kunge iri nenzira yekuti resin inoyerera zvakanaka uye zvakaenzana mumatanho akawanda.Unhu hwechigadzirwa chekupedzisira hunoenderana nekuenderana kwemaitiro ese.
Raw Materials Anoshandiswa muPlastiki Extrusion Process
Yakasiyana epurasitiki zvigadzirwa zvinogona kupiswa uye kugadzirwa mune inoenderera mbiri.Makambani anoshandisa zvinhu zvakasiyana-siyana, zvinosanganisira polycarbonate, PVC, zvinhu zvakadzokororwa, naironi uye polypropylene (PP).
