Zvakakodzera zvekuwedzera zvinodikanwa kugadzirisa pamusoro pepolymer nehupfu hwehuni kuti uvandudze hukama pakati pehupfu hwehuni neresin.
Kupararira kwehupfu hwehuni nehuwandu hwekuzadza mune yakanyungudutswa thermoplastic haina kunaka, izvo zvinoita kuti kunyungudika kunyungudika kuve kusina kunaka uye maitiro eextrusion akaoma.Yepamusoro kurapwa mumiriri inogona kuwedzerwa kuti ivandudze fluidity kufambisa iyo extrusion maitiro.
Iyo matrix epurasitiki inodawo kuwedzera zvakasiyana-siyana zvekuwedzera kuti ivandudze mashandiro ayo uye mashandisiro ekushandisa kwezvigadzirwa zvayo.
Chimiro chehupfu chehuni chakasununguka, uye hazvisi nyore kudyisa extruder screw.Kunyanya, chiitiko che "bridging" uye "danda rekubata" rinowanzoitika kana hupfu hwehuni huine mvura yakawanda.
Kusagadzikana kwekudya kunotungamira kuextrusion fluctuation, zvichikonzera kuderedzwa kweextrusion quality uye kubuda.Kuvhiringidzwa kwekudyisa kunowedzera nguva yekugara kwezvinhu zviri mubhodhoro, izvo zvinozotungamirira mukutsva uye kuchinja kwemavara uye kukanganisa mukati mehutano uye kuonekwa kwezvigadzirwa.
Iyo yekumanikidza yekudyisa mudziyo uye inonzwisisika nzira yekufambisa inogamuchirwa kuti ive nechokwadi chekugadzikana kweextrusion.
Exhaust panguva yekugadzirisa
Iyo diki molecule inovhuvhuta nyaya uye mvura iri muhupfu hwehuni zviri nyore kwazvo kuunza hurema kune zvigadzirwa, uye pretreatment haigone kubvisa zvachose.Naizvozvo, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune dhizaini yekuburitsa system yehuni yepurasitiki composite extruder kupfuura iyo yakajairwa epurasitiki extruder.Kana zvichidikanwa, kupera kwematanho akawanda kunogona kuitwa.
Kusvika pamwero mukuru, zviri nani kupera simba, zviri nani kunaka kwezvigadzirwa zve extruded.
