Amanzi asemabhodleleni aya ngokuya ethandwa, kodwa inkinga yephunga lamanzi okuphuza asemabhodleleni e-PET kancane kancane idonse ukunaka kwabathengi.Yize ingaphazamisi inhlanzeko nempilo, isadinga ukunakwa okwanele ezinkampanini ezikhiqizayo, izinkampani zezimpahla kanye nezinkampani ezithengisayo.
Amanzi ebhodlela le-PET akhiwe ngamanzi, ibhodlela le-PET kanye nekepisi lepulasitiki.Amanzi awanawo umbala futhi awanuki, anezingxenye ezinephunga elincanyana ezincibilikisiwe kuwo, azoveza ukunambitheka okungajabulisi lapho kudliwe.Pho, livelaphi iphunga emanzini?Ngemuva kocwaningo nokuhlolwa okuningi, abantu sebefinyelele esiphethweni esijwayelekile: Ngaphezu kwezinto ezisele zokuwashwa kwamabhodlela nesibulala-magciwane, iphunga emanzini livela ikakhulukazi ezintweni zokupakisha.Ukubonakaliswa okuyinhloko yizi:
1. Iphunga lezinto zokupakisha
Nakuba izinto zokupakisha zingenaphunga ekamelweni lokushisa, lapho izinga lokushisa lingaphezu kuka-38°C isikhathi eside, izinto ezincane zamangqamuzana ezintweni zokupakisha zijwayele ukuguquka futhi zithuthele emanzini, zibangele iphunga.Izinto ze-PET nezinto ze-HDPE ezakhiwe ngama-polymers zizwela kakhulu izinga lokushisa.Ngokuvamile, lapho izinga lokushisa liphakeme, iphunga liba likhulu.Njengoba ezinye izinto zamangqamuzana aphakathi nendawo neziphansi zihlala ku-polymer, emazingeni okushisa aphezulu, iphunga elimnandi kune-polymer.Gwema ukuthutha nokugcina ngaphansi kwezimo zokushisa eziphezulu ukuze ugweme ngokuphumelelayo ukukhiqizwa kwephunga.
2. Ukucekelwa phansi kwezithasiselo ku-raw cap yebhodlela
Inhloso eyinhloko yokwengeza i-lubricant ukuthuthukisa ukusebenza kokuvula kwe-cap yebhodlela nokwenza kube lula kubathengi ukuphuza;ukwengeza i-ejenti yokukhululwa ukuze kube lula ukukhululwa kwe-cap kusuka ekubunjeni lapho wenza i-cap;ukwengeza umbala we-masterbatch ukuze ushintshe umbala wekepisi futhi uhlukanise ukubukeka komkhiqizo.Lezi zithako ngokuvamile ziqukethe ama-amide anamafutha angagcwalisiwe, lapho ukwakheka kwe-double bond C=C kufakwe i-oxidized kalula.Uma echayeke ekukhanyeni kwe-ultraviolet, izinga lokushisa eliphakeme, ne-ozone, lesibopho esikabili singavulwa ukuze kwakhe ingxube eyonakele: ama-acid agcwele amafutha angagcwalisiwe, i-acetaldehyde, ama-carboxylic acid, nama-hydroxides, njll., angancibilika kalula emanzini futhi akhiqize okuhlukile. ukunambitheka.kanye nephunga.
3. Izinsalela zephunga ezikhiqizwa ngesikhathi sokwenza i-cap
Izinto ezisetshenziselwa ukwenza ama-caps zengezwa nezithasiselo ezifana nezithambisi.Ukwenziwa kwekhephu kufaka phakathi izinqubo ezifana nokushisisa nokunyakazisa kwemishini ngesivinini esikhulu.Iphunga ngenxa yokucubungula lihlala esivalweni futhi ekugcineni lizothuthela emanzini.
Njengomkhiqizi owaziwayo we-bottle cap, i-Mingsanfeng Cap Mold Co., Ltd. inikeza amakhasimende izixazululo ze-bottle cap ezihlanganisa ukuklama, ucwaningo nentuthuko, ukukhiqiza, ukuthengisa kanye nesevisi.
