PET Flake/scrap dehumidifier crystallizer

Kufotokozera Kwachidule:

Reprocessing flakes mu extruder amachepetsa IV chifukwa hydrolysis i kukhalapo kwa madzi, ndi chifukwa chake chisanadze kuyanika kwa homogeneous kuyanika mlingo ndi IRD System athu akhoza kuchepetsa kuchepetsa uku. Kuphatikiza apo, utomoni umakhala wachikasu chifukwa nthawi yowuma imachepetsedwa (Kuyanika nthawi kumangofunika 15-20mins, chinyezi chomaliza chikhoza kukhala≤ 50ppm, kugwiritsa ntchito mphamvu zosakwana 60W/KG/H), ndi kumeta ubweya mu extruder potero kumachepetsanso chifukwa preheated zinthu amalowa extruder pa kutentha zonse”

Kuchulukana kwa ma flakes pambuyo pa IRD: kuchuluka kwa 15-20%
Chinyezi chomaliza : ≤30ppm
Viscosity: Kuchepetsa kuwonongeka kwa hydrolytic kwa mamasukidwe akayendedwe.

Kutulutsa

>> Poyambira, cholinga chokha ndikutenthetsa zinthuzo kuti zitenthedwe.
Landirani kuthamanga kwapang'onopang'ono kwa ng'oma yozungulira, mphamvu ya nyali ya infrared ya chowumitsira idzakhala pamlingo wapamwamba, ndiye ma pellets a PET azikhala ndi kutentha mwachangu mpaka kutentha kumakwera mpaka kutentha komwe kunakhazikitsidwa.

>> Kuyanika & Crystallizing sitepe
Zinthu zikafika kutentha, liwiro la ng'oma lidzawonjezedwa mpaka liwiro lozungulira kwambiri kuti lisagwirizane ndi zinthuzo. Nthawi yomweyo, mphamvu ya nyali ya infrared idzawonjezedwanso kuti amalize kuyanika. Ndiye liwiro lozungulira ng'oma lidzachepetsedwa kachiwiri. Nthawi zambiri, kuyanika kumatha pambuyo pa mphindi 15-20. (Nthawi yeniyeni imadalira katundu wa zinthu)

>> Akamaliza kuyanika, IR Drum imangotulutsa zinthuzo ndikudzazanso ng'omayo kuti ibwererenso.
Kubwezeretsanso kokha komanso magawo onse ofunikira pazigawo zosiyanasiyana za kutentha kumaphatikizidwa kwathunthu muulamuliro wamakono wa Touch Screen. Magawo ndi mawonekedwe a kutentha akapezeka pazinthu zinazake, zokonda zamalingaliro zitha kusungidwa ngati maphikidwe mudongosolo lowongolera.

Ubwino Wathu

Nthawi zambiri Botolo la PET limaphulika kapena zidutswa za pepala zokhala ndi chinyezi choyambirira mpaka 10000-13000ppm. Botolo la PET kapena zidutswa za pepala (Namwali kapena zosakanikirana) zidzasinthidwanso mu Infrared crystal dryer mu 20mins, kutentha kowuma kudzakhala 150-180 ℃ ndikuwumitsidwa mpaka 50-70ppm, kenaka kudyetsedwa ku Single screw extruding system kuti ipitirire.
