Infrared Mbere yo Kuma ya PET Flakes: Kongera Ibisohoka no Kuzamura Ubwiza kuri PET Extruders
>> Gusubiramo flake muri extruder bigabanya IV kubera hydrolysis i ahari amazi,niyo mpamvu mbere yo gukama kugeza kurwego rumwe rwumye hamwe na sisitemu ya IRD irashobora kugabanya uku kugabanuka.Mubyongeyeho, resin ntabwo iba umuhondo kuko igihe cyo kumisha kigabanuka (Igihe cyo kumisha gikenera 15-20mins gusa, ubuhehere bwa nyuma burashobora≤ 50ppm, gukoresha ingufu zitarenze 80W / KG / H.), no kogosha muri extruder na byo bigabanuka kuko ibikoresho bishyushye byinjira muri extruder ku bushyuhe buhoraho ”
>> Mu ntambwe yambere, PET regrind irabikwa kandi ikuma imbere muri IRD mugihe cyiminota 15.Ubu buryo bwo korohereza no gukama bigerwaho nuburyo butaziguye bwo gushyushya hakoreshejwe imirasire ya Infrared, kugirango ubushyuhe bwibintu bwa 170˚C.Bitandukanye na sisitemu ishyushye yumuyaga mwinshi, imbaraga zihuse kandi zitaziguye zorohereza kuringaniza neza indangagaciro zihindagurika zihoraho - sisitemu yo kugenzura imirasire ya IR yemerera gusubiza ibintu byahinduwe mumasegonda.Muri ubu buryo, indangagaciro ziri hagati ya 5.000 na 8000 ppm zigabanywa kimwe imbere muri IRD kugeza kurwego rusigaye rwa 30-50ppm.
>>Nka ngaruka ya kabiri yuburyo bwo gutegera muri IRD, ubwinshi bwibintu byubutaka byiyongera,cyane muri flake-uburemere cyane.Izi ngaruka za kabiri zirashimishije cyane inyuma yinyuma yerekana ko kugana amacupa yometseho uruzitiro rurinda ibikoresho byo gutunganya ibintu bitagera ku bunini bwa> 0.3 kg / dm³.Kwiyongera k'ubucucike bwa 10 kugeza kuri 20% birashobora kugerwaho muri IRD, bigaragara ko idafite agaciro ukimara kubibona, ariko igateza imbere imikorere yibiryo kuri enterineti - mugihe umuvuduko wa extruder udahinduka, hari byinshi byahinduwe neza kuzuza imikorere kuri screw.
