| 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 ℃ ndikuwumitsa mpaka 150-300ppm, kenaka kudyetsedwa ku Double screw extruding system kuti ipitirire.
>> Kuchepetsa kuwonongeka kwa hydrolytic kwa mamasukidwe akayendedwe
>>Pewani kuchuluka kwa AA pazakudya 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
>> Makhalidwe apamwamba azinthu zomaliza ---Zofanana komanso zobwerezabwereza zomwe zimakhala ndi chinyezi chazinthuzo
