Ekuphileni kwansuku zonke, sizothola ukuthi imikhiqizo eminingi yepulasitiki izoba nephunga elithile lapho iqala ukusetshenziswa.Isibonelo, eminye imikhiqizo evamile ye-polyethylene ne-polypropylene izoba nephunga elishunqayo ekuqaleni kokusetshenziswa, futhi iphunga liyoba lincane kakhulu ngemva kwesikhathi sokusetshenziswa., Kungani le mikhiqizo yepulasitiki iphunga?
Lezi phunga kumapulasitiki ikakhulukazi zivela ezithasiselweni ezengezwe enqubweni yokukhiqiza ipulasitiki.Lokhu kungenxa yokwengezwa kwama-solvents kanye nenani elincane labaqalisi nezinye izithasiselo ngesikhathi se-polymerization ye-polyethylene ne-polypropylene resins.Ngemuva kokugeza, ukuhlunga, njll., ngezinye izikhathi inani elincane lezinsiza ezishiwo ngenhla lizohlala, futhi ngaphezu kwalokho, inani elincane le-polymer eliphansi-molecular-weight lizohlala ku-resin.Ngesikhathi sokubunjwa nokucubungula imikhiqizo yepulasitiki, lezi zinto zizovezwa emazingeni okushisa aphezulu ukuze zibalekele iphunga elingajwayelekile futhi zihlale phezu komkhiqizo.
Ngaphezu kwalokho, abanye abakhiqizi bazokwengeza i-turpentine njengosizo lokudaya lapho kudaywa ngepulasitiki.Uma isetshenziswe kakhulu, iphunga le-turpentine nalo lizophuma emkhiqizweni.Inyamalala kancane futhi ayinamthelela empilweni yomuntu.Kodwa-ke, uma iphunga linzima kakhulu futhi likhona isikhathi eside, lizoba nomthelela othile empilweni yomuntu.
Ngakho-ke, lapho sithenga imikhiqizo yepulasitiki, kufanele sikhethe imikhiqizo yepulasitiki enezinto zokusetshenziswa eziphephile, ikhwalithi enhle kanye nesici sokuphepha esiphezulu.
