Izinga lokusetshenziswa kwamapulasitiki e-China lingama-25% kuphela, futhi amathani ayizigidi eziyi-14 amapulasitiki alahlwayo awakwazi ukugaywa kabusha futhi aphinde asetshenziswe ngesikhathi minyaka yonke.Amapulasitiki alahlwayo angakhiqiza zonke izinhlobo zemikhiqizo yepulasitiki egaywe kabusha noma izibaseli ngokuchotshozwa, ukuhlanza, ukuvuselela imbudumbudu, noma ukuqhekeka, okunenani eliphezulu lokugaywa kabusha.Enqubweni yokusebenzisa amapulasitiki, nakanjani izongcoliswa yizo zonke izinhlobo zokungcola, futhi izinhlobo ezahlukene zokungcola okunamathiselwe zizokwakhiwa phezu kwayo.Umshini wokuwasha kabusha wepulasitiki ungasusa ukungcola okunamathiselwe endaweni yepulasitiki, uthuthukise ukunemba kokuhlonza nokuhlukanisa, futhi uthinte ngokuqondile ikhwalithi yemikhiqizo yepulasitiki egaywe kabusha.Kuwukhiye wokugaywa kabusha kwamapulasitiki alahlwayo.
Nalu uhlu lokuqukethwe:
Yiziphi izinhlobo zokungcola okuvela kumapulasitiki alahlwayo?
Izinhlobo nemithombo yemfucuza yepulasitiki ihlukile, futhi izinhlobo zokungcola nezinhlobo zokungcola nazo zihlukile.Ihlanganisa ikakhulukazi ukungcoliswa kwento encibilikisiwe, ukungcoliswa kwezinto eziphilayo, ukungcoliswa kwenani le-pH, ukungcoliswa kothuli, ukungcoliswa kukawoyela, ukungcoliswa kombala nemibala, ukungcoliswa kwezinto ezinobuthi, ukungcoliswa kwe-organic binder, ukungcoliswa kwe-microbial, uthuli, imfucuza engeyona i-polymer, njll.
Ithini indlela yokugezaumshini wokuwasha plastic?
Izindlela zokuwasha zemishini yokuwasha kabusha yepulasitiki zifaka ukuhlanza amanzi, ukuhlanzwa kwe-ultrasonic, ukuhlanzwa kwe-anhydrous, ukuhlanza iqhwa elomile, ukuhlanza i-microwave, njll.
Ukuhlanza amanzi kuyindlela evame ukusetshenziswa kakhulu yokuhlanza amapulasitiki agaywe kabusha ezinsizakalweni zokupakisha zepulasitiki.Enqubweni yokuhlanza imithombo yamanzi, ukuhlanza kwenziwa ngezinyathelo ezimbili.Amanzi ajikelezayo asetshenziswa ngesikhathi sokuhlanza okungalungile.Amanzi akhishwe ohlelweni lokuhlanza angangena ohlelweni lokuhlanza, futhi amanzi angcolile kuphela akhishwa ngesikhathi sokuhlanza.Ama-fatty alcohol ethoxylates ahambisana nemvelo angaboli kanye nama-polyethylene glycol surfactants azokhethwa ukuze kuhlanzwe amapulasitiki angcolile.Ngesikhathi sokuhlanza i-deinking, i-degumming kanye nokususwa kwepende, isisombululo se-ejenti yokuhlanza ohlelweni lokucwilisa sizofaka inqubo elandelayo kancane ngangokunokwenzeka, engagwenywa ngokukhipha amanzi ngemva kokukhipha.
Ukuhlanza nge-Ultrasonic kuwumsebenzi womzimba.Imodeli yokusetshenziswa ifanele ukuhlanza ukungcola okungcolile kanye nemfucumfucu ku-substrate yepulasitiki, engavinjelwe uhlobo lwemisebe nokunamathela kwefilimu, ikakhulukazi ukuhlanza ifilimu kahle.I-ejenti yokuhlanza i-ultrasonic isebenzisa i-solvent yamakhemikhali noma i-ejenti yokuhlanza esekelwe emanzini.
Umoya usetshenziswa njengendawo yokuhlanza yokuhlanza i-anhydrous, ngakho-ke akukho ndle kuyo yonke inqubo yokuhlanza, futhi okunye ukungcola okufana nenhlabathi nothuli kuqoqwa ngendlela emaphakathi, ngaphandle kokungcoliswa kwesibili, ukonga imithombo yamanzi kanye nokunciphisa izindleko ngo-30 %.Ukuhlanzwa kwe-anhydrous eluhlaza (ukuhlanza okomile) kwefilimu yokupakisha imfucuza kuwumkhakha obalulekile wocwaningo olufanele njengamanje.Ubuchwepheshe bokuhlanza i-anhydrous, inqubo, kanye nemishini kusesigabeni sokuhlola.
Imboni yokugaywa kabusha kwepulasitiki eyimfucuza iyimboni yokuphuma kwelanga ezuzisa izwe kanye nabantu.Kungamandla abalulekile ekwakheni umphakathi owonga ugesi kanye nokuthuthukisa umnotho oyindilinga.Ukugaywa kabusha kwanoma yiluphi uhlobo lwepulasitiki kumele kudlule ohlelweni oluqinile lokuhlanza, okuletha namathuba amahle ebhizinisi embonini yokuhlanza.I-Suzhou Polytime Machinery Co., Ltd. inesipiliyoni seminyaka eminingi embonini yepulasitiki futhi isungule izikhungo eziningi zokuthengisa ekhaya naphesheya.Uma ubambe iqhaza embonini yomshini wokuwasha kabusha wepulasitiki noma umsebenzi ohlobene, ungacabangela imikhiqizo yethu yobuchwepheshe obuphezulu.
