Zinthu zolimba zokonzedwa ndi botolo la pulasitiki la PET.

Zinyalala za polyethylene terephthalate (PET) zimatha kuwonongeka kwambiri pambuyo pa chithandizo chimodzi kapena zingapo.Ngati palibe njira zowongolera zomwe zimatengedwa ndikugwiritsidwa ntchito mwachindunji popanga, ntchito yokonza ndi zinthu zopangidwa zidzakhudzidwa.The makina katundu adzakhala osauka kwambiri, maonekedwe adzakhala achikasu, sangathe kukwaniritsa zofunika ntchito, chifukwa kuwonongeka kwa poliyesitala ntchito, kuchepetsa khalidwe mamasukidwe akayendedwe poliyesitala, ma discoloration, carboxyl kuwonjezeka, sangathe kukwaniritsa zofunika ntchito.

Nthawi yomweyo, chifukwa cha kutentha kwa magalasi a PET ndi malo osungunuka ndi okwera kwambiri, kutentha kwa nkhungu, kutsika kwapang'onopang'ono, komanso kukula kwa utomoni wolemera ndi kuchepa, mawonekedwe a kristalo ndi osagwirizana, kupanga njira kumakhala kovuta, kupanga kuzungulira ndi yaitali, mankhwala pamwamba akhakula, chonyezimira.Kupanda mphamvu, kulimba kwamphamvu komanso kuyamwa kwamadzi kwa PET kumachepetsa kwambiri kugwiritsa ntchito kwachiwiri.

Chitsanzochi chimagwiritsa ntchito zinyalala za PET kukonza zinthu zolimba za PET, powonjezera zowonjezera kuti mupangePET toughening zinthu, imatha kukonzedwa ndi makina abwino, kukana kwabwino, kukana kusinthasintha, kukana mafuta, kukana mafuta, asidi ndi kukana kwa alkali kwa PET toughening material.Ndipo zosungunulira organic, kutentha kwambiri ndi otsika kutentha kukana, sanali poizoni, zoipa,zinthu zowoneka bwino za PET.
