Vuto la Cutomer's Key pogwiritsa ntchito mzere wa Double-screw PET Sheet Extrusion wokhala ndi vacuum degassing | |
1 | Vuto lalikulu ndi Vacuum system |
2 | Final PET Mapepala ndi brittleness |
3 | Kumveka kwa PET Mapepala ndikoyipa |
4 | Kutulutsa sikukhazikika |
Zomwe tingakuchitireni
Nthawi zambiri Botolo la PET limaphulika kapena zidutswa za pepala zokhala ndi chinyezi choyambirira mpaka 8000-10000ppm. Botolo la PET kapena zidutswa za pepala (Namwali kapena zosakanikirana) zidzasinthidwanso mu Infrared crystal dryer mu 10-15mins, kutentha kowuma kudzakhala 150-180 ℃ ndikuwumitsidwa mpaka 150-300ppm, kenaka kudyetsedwa ku Double screw extruding system kuti ipitirire.
>> Kuchepetsa kuwonongeka kwa hydrolytic kwa mamasukidwe akayendedwe
>>Pewani kuchuluka kwa ma AA pazida zolumikizana ndi chakudya
>> Kuchulukitsa kuchuluka kwa mzere wopanga mpaka 50%
>> Kuteteza milingo yofanana ya chinyezi kwa extruder
>>Kuchita mosasinthasintha kwa vacuum degassing poyerekeza ndi zinthu zosauma
>> Ubwino wapamwamba wazinthu zomaliza ---Chinyezi chofanana komanso chobwerezabwereza chazinthuzo
