Zowonjezera zoyenera zimafunika kuti zisinthe pamwamba pa polima ndi ufa wamatabwa kuti zithandizire kulumikizana pakati pa ufa wamatabwa ndi utomoni.
Kumwazika kwa ufa wa nkhuni wokhala ndi kuchuluka kodzaza mu thermoplastic yosungunuka ndikosakwanira, zomwe zimapangitsa kusungunuka kwamadzi kukhala kovutirapo komanso njira yotulutsa mpweya kukhala yovuta.Pamwamba mankhwala wothandizira akhoza kuwonjezeredwa kusintha fluidity kuti atsogolere ndondomeko extrusion.
Matrix apulasitiki amafunikanso kuwonjezera zowonjezera zosiyanasiyana kuti apititse patsogolo kagwiritsidwe ntchito ka zinthu zake.
Mapangidwe a ufa wa nkhuni ndi otayirira, ndipo sikophweka kudyetsa wononga phula.Makamaka, chodabwitsa cha "kutsekereza" ndi "kugwirizira mzati" nthawi zambiri zimachitika pamene ufa wa nkhuni uli ndi madzi ambiri.
Kusakhazikika kwa chakudya kumabweretsa kusinthasintha kwa extrusion, zomwe zimapangitsa kuchepa kwa khalidwe la extrusion ndi linanena bungwe.Kusokonezeka kwa kudyetsa kudzatalikitsa nthawi yokhalamo zinthu zomwe zili mu mbiya, zomwe zingayambitse kuyaka ndi kusinthika kwa zinthuzo komanso kukhudza khalidwe lamkati ndi maonekedwe a zinthuzo.
The mokakamizidwa kudyetsa chipangizo ndi wololera kutengera mode anatengera kuonetsetsa bata wa extrusion.
Kutopa pa processing
Kachidutswa kakang'ono ka molekyulu yosasunthika ndi madzi omwe ali mu ufa wa nkhuni ndizosavuta kubweretsa zolakwika kuzinthu, ndipo pretreatment sangathe kuzichotsa kwathunthu.Choncho, chidwi kwambiri ayenera kuperekedwa kwa kamangidwe ka utsi dongosolo matabwa pulasitiki gulu extruder kuposa wamba pulasitiki extruder.Ngati ndi kotheka, kutulutsa kwamitundu yambiri kumatha kuchitika.
Pamlingo waukulu, kutulutsa kwabwinoko kumapangitsa kuti zinthu za extruded zikhale zabwinoko.
