Izinkinga ezinkulu zokupakishwa okuguquguqukayo ekuqondeni kwentuthuko yesikhathi esizayo (ukupakishwa okuzenzakalelayo) Isiqephu3

4, Inkinga ye-PE yokubeka uphawu okushisayo
Ngesikhathi senqubo yokuvala ukushisa kwefilimu eyinhlanganisela, i-PE ivame ukukhishwa futhi inamatheleifilimu yokuqinisa ukushisa.Lapho inqwabelana kakhulu, ithinta kakhulu ukukhiqizwa okuvamile.Ngasikhathi sinye, i-PE ekhishiwe ikhipha i-oxidize futhi ibheme endaweni yokuvala ukushisa, ikhiphe iphunga elingavamile.Ngokuvamile, i-PE ingakhishwa ngokuvala ukushisa ngokunciphisa izinga lokushisa lokuvalwa kokushisa nokucindezela, ukulungisa ifomula yesendlalelo sokuvala ukushisa, nokuguqula ifilimu yokuvala ukushisa ukuze kuncishiswe ingcindezi emaphethelweni ayo.Kodwa-ke, umkhuba ufakazele ukuthi isisombululo esingcono kakhulu ukusebenzisa inqubo ye-extrusion composite ukukhiqiza ifilimu ehlanganisiwe, noma ukuthuthukisa isivinini somshini wokupakisha, ukuze i-PE ingakwazi ukukhishwa kwifilimu yokuvala ukushisa ngesikhathi.

5. Ukubhoboza uphawu olushisayo nokuphuka
Ukubhoboza kubhekisela ekwakhekeni kwembobo engena ngaphakathi noma ukuqhekeka ngenxa yokukhishwa kwezinto zokupakisha ngamandla angaphandle.Izimbangela ngokuvamile zihlanganisa:

A: Ingcindezi yokuvala ukushisa iphezulu kakhulu.Enqubweni yokuvala ukushisa, uma ingcindezi yokuvala ukushisa iphezulu kakhulu noma i-fat-seal-seal die ingahambisani, okuholela ekucindezelweni okukhulu kwendawo, ezinye izinto zokupakisha ezintekenteke zivame ukucindezelwa.

B: Idayizi yokuvala ukushisa ilukhuni futhi inemiphetho namakhona noma izinto zangaphandle.Izinto zokupakisha zivame ukulinyazwa ifa elisha lokuvala ukushisa ngokukhiqiza okungekuhle.Okunye ukufa kwe-heat-sealing kuzokhiqiza imiphetho ebukhali namakhona ngemva kokushaywa, okuyinto elula kakhulu ukuyicindezela.izinto zokupakisha.

C: Ubukhulu bezinto zokupakisha azikhethwanga ngendlela efanele.Eminye imishini yokupakisha inezidingo ebukhulu bezinto zokupakisha.Uma ubukhulu bukhulu kakhulu, ezinye izingxenye zezikhwama zokufaka zingacindezelwa.Isibonelo, ubukhulu bohlobo lomcameloimpahla yokupakisha yomshini wokupakishangokuvamile akufanele kube ngaphezu kuka-60um.Uma impahla yokupakisha iwugqinsi kakhulu, ingxenye yophawu olumaphakathi yohlobo lomcamelo iphuka kalula.

D: Isakhiwo sezinto zokupakisha asikhethiwe ngendlela efanele.Ezinye izinto zokupakisha azikwazi ukumelana nengcindezi futhi azikwazi ukusetshenziselwa ukupakisha izinto eziqinile ezinamachopho namakhona.

E: Idizayini yesikhunta yephakheji ayilungile.Enqubweni yokuklama, uma imbobo yokubumba ye-fat-sealing die ingahambelani nokuma nobukhulu bephakheji, futhi amandla omshini wempahla yokupakisha ayiphezulu, kulula futhi ukuyicindezela noma ukuphuka.impahla yokupakishaphakathi nenqubo yokupakisha.
