Chida cholimba chopangidwa kuchokera ku botolo la pulasitiki la PET.

ZinyalalaPET (polyethylene terephthalate)imawonongeka kwambiri pambuyo pa chithandizo chimodzi kapena zingapo. Ngati palibe njira zolipirira zogwiritsidwa ntchito mwachindunji popanga, ntchito yokonza ndi zomwe zimapangidwa zidzakhudzidwa. The makina katundu adzakhala osauka kwambiri, maonekedwe achikasu, sangathe kukwaniritsa zofunika ntchito, zikubweretsa kuwonongeka kwa poliyesitala ntchito, kuchepetsa khalidwe mamasukidwe akayendedwe poliyesitala, ma discoloration, carboxyl gulu kuwonjezeka, sangathe kukwaniritsa zofunika ntchito.

Panthawi imodzimodziyo, chifukwa kutentha kwa kusintha kwa magalasi a PET ndi malo osungunuka ndi okwera kwambiri, kutentha kwa nkhungu kumakhala kwakukulu, kuthamanga kwa crystallization kumakhala pang'onopang'ono ndipo kumachepa ndi kuwonjezeka kwa kulemera kwa maselo a utomoni, kotero kuti mawonekedwe a kristalo sali ofanana, kuumba kumakhala kovuta. , kuumba mkombero ndi yaitali, mankhwala pamwamba ndi akhakula ndi chonyezimira. Kuipa kwa mphamvu zopanda mphamvu, kusalimba kwamphamvu komanso kuyamwa kwambiri kwamadzi kumachepetsa kwambiri kugwiritsa ntchito kwachiwiri kwa PET.

Chitsanzochi chimagwiritsa ntchito zinyalalaPET zinthuKukonzekera PET toughening zakuthupi, powonjezera zowonjezera zopangidwa ndi PET toughening material, zimatha kukonza makina abwino, kukana kukhudzidwa, kuyendetsa bwino, kukana mafuta, kukana mafuta, asidi ndi alkali kukana ndi zina zabwino kwambiri za PET toughening material. Ndi zosungunulira organic, kutentha kwambiri komanso kukana kutentha kwapansi, zopanda poizoni, zopanda pake, zowonekera bwino za PET.
