Kuma yumye birashobora kugaragara cyanekunoza imikorere ya twin-screw extruder kuko igabanya gutesha agaciro agaciro ka IV kandi igatezimbere cyane ituze ryibikorwa byose.
Ubwa mbere, PET isubiramo izashyirwa hamwe hanyuma yumirwe muminota 15-20 imbere muri IRD.Ubu buryo bwo korohereza no gukama bigerwaho nuburyo bwo gushyushya butaziguye hakoreshejwe imirasire ya infragre kugirango ugere ku bushyuhe bwibintu bya 170 ° C.Ugereranije no gutinda sisitemu yumuyaga mwinshi, byihuse kandi bitaziguye byinjiza bigira uruhare muburinganire bwuzuye bwimihindagurikire yigihe cyose agaciro kinjiza - sisitemu yo kugenzura imirasire yimirasire irashobora gusubiza ibintu byahindutse mumasegonda.Muri ubu buryo, agaciro kari hagati ya 5.000 na 8000 ppm imbere muri IRD kagabanutse kimwe kugeza kubushuhe busigaye bwa 150-200 ppm.
Nkingaruka ya kabiri yuburyo bwo gutegera muri IRD, ubwinshi bwibintu byajanjaguwe byiyongera, cyane cyane muburemere bworoshye cyane.Muri ubu buryo:IRD irashobora kongera ubwinshi bwubwinshi bwa 10% kugeza kuri 20%, ibyo bisa nkaho ari itandukaniro rito cyane, ariko birashobora kunoza cyane imikorere yimirire kumurongo winjira - nubwo umuvuduko wa extruder ukomeza kuba umwe, birashobora kunoza cyane imikorere yuzuza imigozi.
Nuburyo bwubushyuhe bwo hejuru bwo korohereza no gukama, sisitemu ya IRD irashobora kandi gushushanywa nkumuti wihuse kugirango ukore neza kandi mubushyuhe bwumutse munsi ya 120 ° C.Muri iki gihe, ibirimo ubuhehere byagezweho bizagarukira kuri "gusa" hafi 2,300 ppm, ariko muri ubu buryo birashobora kubungabungwa mu buryo bwizewe, cyane cyane mu ndangagaciro zagenwe n’uruganda rukora ibicuruzwa.Ikindi kintu cyingenzi nukwirinda ihindagurika ryinshi kandi rihoraho mugaciro, hamwe nubushyuhe bwo kugabanuka bugera kuri 0,6% bizagabanya cyane ibipimo bya IV mubikoresho bya pulasitike bishongeshejwe.Igihe cyo gutura cyumye gishobora kugabanuka kugeza ku minota 8.5 kandi gukoresha ingufu biri munsi ya 80 W / kg / h
