WastePET (polyethylene terephthalate)inodzikira zvakanyanya mushure mekurapwa kumwe kana kupfuura. Kana pasina matanho anotorwa kutsiva kushandiswa kwakananga mukugadzira, mashandiro ekugadzirisa uye chigadzirwa chinogadzirwa chinokanganiswa. Iyo mechanical pfuma ichave yakashata kwazvo, kutaridzika kweyero, haigone kusangana nezvinodiwa zvekushandisa, zvichitungamira mukuipa kwekuita kwepolyester, kuderedza hunhu viscosity yepolyester, discoloration, carboxyl boka kuwedzera, haigone kusangana nezvinodiwa zvekushandisa.
Panguva imwecheteyo, nekuti PET girazi rekushandura tembiricha uye nzvimbo yekunyunguduka yakakwira, kupisa kwemukuvhu kwakakwira, crystallization kumhanya inononoka uye inoderera nekuwedzera kwemamolecular uremu hweresin, saka chimiro chekristaro hachina yunifomu, maitiro ekuumba akaoma. , kuumbwa kutenderera kwakareba, chigadzirwa chepamusoro chakashata uye chinopenya. Kuipa kwesimba rakashata, kusasimba kwekusimba uye kunyura kwemvura kwakakwira kunodzikamisa zvakanyanya kushandiswa kwechipiri kwePET.
Uyu muenzaniso unoshandisa tsvinaPET zvinhukugadzirira PET inoomesera zvinhu, nekuwedzera zvinowedzerwa zvakaitwa PET toughening zvinhu, zvinogona kugadzirira yakanaka makina zvivakwa, yakanaka kukanganisa kuramba, kuita kwakanaka kupeta, mafuta kuramba, mafuta kuramba, asidhi uye alkali kuramba uye zvimwe zvakanakisa zvimiro zvePET toughening zvinhu. Iine organic solvent, tembiricha yakakwira uye yakaderera tembiricha kuramba, isiri-chepfu, isingaravike, yakanaka kujeka PET zvinhu.
