Ukusetshenziswa kwefilimu enayiloni ekufakweni kokudla kwezilwane ezifuywayo

Emazweni asentshonalanga, "umnotho wezilwane" uyimboni enkulu.Uma sithatha ukudla kwesilwane esifuywayo njengesibonelo, iNyakatho Melika (ikakhulukazi i-United States) iyimakethe yabathengi enkulu kunazo zonke zokudla kwezilwane ezifuywayo, futhi ilandisa ngenani elikhulu lokuthengisa.IWestern Europe iyimakethe yabathengi ehamba phambili kuzo zonke ezinye izigaba zokudla kwezilwane ezifuywayo, futhi iyimakethe yesibili ngobukhulu yabathengi yokudla kwezinja namakati.Phakathi kwazo, ukuthuthukiswa komnotho wezilwane ezifuywayo e-United States naseJapane kuvelele kakhulu.

Izinkinga ezivame ukwenzeka esimweni samanje semakethe

E-China, bayanda abantu abanezilwane ezifuywayo.Ngokukhula kwenani lezilwane ezifuywayo, uchungechunge lwezimboni ezihlobene luye lwavela emnothweni wezilwane ezifuywayo, njengokudla kwezilwane ezifuywayo, ukunikezwa kwezilwane ezifuywayo, ukwelashwa kwezilwane ezifuywayo, imboni yobuhle bezilwane ezifuywayo, njll., okuzoba nethemba elibanzi lemakethe.Ukupakishwa kokudla kwesilwane esifuywayo kuzoba enye yezindawo ezishisayo emkhakheni wokupakisha ngokuzayo.

Ukuthatha ukudla kwezilwane ezifuywayo njengamakati nezinja njengesibonelo, izinto ezingavuthiwe ikakhulukazi imikhiqizo yenyama.

Izici zayo zihlanganisa izici ezimbili ezilandelayo:

1. Ukuze ugcine ukunambitheka kokudla kwesilwane esifuywayo, izithako akufanele zenziwe zithambile kakhulu noma zibe yimpuphu ngesikhathi sokukhiqiza.Kuyadingeka ukugcina ukuqina kanye nokuqina kwenyama, amathambo namathambo ezinhlanzi.Ngakho-ke, ukudla kwezilwane ezifuywayo kubonakala ngesimo esingavamile futhi kuqukethe izinto ezibukhali njengamathambo namathambo ezinhlanzi.

2. Ukudla kwezilwane ezifuywayo ngokuyisisekelo kuwukudla okufakwe imisebe.Ukwelula impilo yeshalofu, ukudla kwezilwane ezifuywayo kudinga ukufakwe imisebe ukuze kubulawe amagciwane.Ukudla okufakwe imisebe kubhekisela ekudleni okucutshungulwa ngemisebe ye-gamma ekhiqizwe i-cobalt-60 kanye ne-cesium-137 noma imishayo yama-electron engaphansi kwe-10MeV ekhiqizwe ama-accelerator ama-electron, okuhlanganisa izinto zokusetshenziswa zokudla ezifakwe imisebe kanye nemikhiqizo eseqediwe kancane.

Njengamanje, ubuchwepheshe bokukhipha imisebe busetshenziswa kabanzi emazweni amaningi ukuze kuqinisekiswe ukuphepha kokudla kanye nokwandisa ukuphila kweshelufu lokudla, futhi kuqashelwa abathengi abaningi ngokwengeziwe.Njengesiqandisi esinezinga lokushisa eliphansi, ukwelashwa okunokushisa okuphezulu nokwelashwa ngamakhemikhali, lobu buchwepheshe bungasusa ama-microorganisms. ezidala ukonakala kokudla kanye nezifo ezitholakala ekudleni ekudleni.Ekupakini kokudla, imisebe iphinde ibe yindlela enhle yokwelula isikhathi seshelufu sokudla.

Ezinhlelweni zokupakisha ze-aseptic, izindlela zokuvala inzalo zezinto zokupakisha zifaka inzalo ye-ultraviolet, izindlela zamakhemikhali kanye nokufakwa inzalo okuhlangene kwe-ultraviolet, inzalo ye-infrared, imisebe ye-ionizing kanye nama-pulses alula.Lapho impahla yokupakisha ingakwazi ukudlula amandla ashisayo noma idlule emisebeni ye-ionizing kuyindlela enhle yokuvala inzalo ebandayo yokubulala amagciwane kanye nokubulala amakhemikhali.

Njengamanje, ukupakishwa kwezilwane ezifuywayo ezivamile emakethe yaseShayina ngokuvamile kusebenzisa indlela yokupakisha yesikhwama se-zipper esinezinhlangothi ezintathu.Ukuze kuthuthukiswe umphumela weshalofu kanye nokusebenza kwesithiyo, abakhiqizi abaningi basekhaya bokupakisha abaguquguqukayo basebenzisa i-VMPET noma i-AL njengesendlalelo sesithiyo;

Izinkinga zokupakishwa kokudla kwezilwane ezifuywayo e-China zifaka lezi zici ezilandelayo:

1. I-VMPET noma i-Al isetshenziswa njengesendlalelo sesithiyo, kodwa imikhiqizo ayikwazi ukubonakala ngokuqondile, ekhawulela umphumela wokuboniswa kweshelufu wemikhiqizo;

2 Njengoba imikhiqizo ingamathambo, amathambo ezinhlanzi nezinye izinto, isikhwama kulula ukubhoboza, okuholela ezinkingeni zekhwalithi.

3 Ukushelela kwesikhwama sokupakisha akukuhle, futhi ukuvulwa kubi enqubweni yokukhiqiza, nokusebenza kahle kokukhiqiza kuphansi.Ngesikhathi esifanayo, kuzophinde kunciphise izinga lokusebenzisa isikhwama sokupakisha futhi kwenyuse izindleko.

4 Ngemva kokukhishwa kwemisebe, izici zemishini eziphelele zesikhwama zehla.

Umbono wokuklama wesakhiwo esiyinhlanganisela sokupakisha ukudla kwezilwane ezifuywayo

Ekukhiqizeni kwangempela, i-irradiation ayinawo umthelela ezintweni zengilazi neziqukathi zensimbi, kodwa inganciphisa ukuguquguquka kanye nezakhiwo zemishini yamapulasitiki.Ngakho-ke, enkambisweni yokuklama, uma kungekho sakhiwo esifanelekile esiyinhlanganisela, isikhwama kulula ukubhoboza futhi izakhiwo zomzimba nezemishini zesikhwama ziyancipha.Ngakho-ke, kubaluleke kakhulu ukutadisha isakhiwo esiyingqayizivele esiyinhlanganisela ukuze uvumelane nomthelela we-irradiation ezindaweni zepulasitiki.

Ukupakishwa kokudla kwesilwane esifuywayo kufanele kuhlangabezane nezidingo ezilandelayo ngesikhathi sokupakishwa kwangempela, ukuthutha, ukugcinwa kanye nokusetshenziswa:

1. Ukusebenza okuhle kwesithiyo

Imikhiqizo yephakeji iwukudla kwezilwane ezifuywayo, okufanele ikwazi ukuhlangabezana nezidingo zokuqinisekiswa kwekhwalithi yemikhiqizo, igcine ikhwalithi kanye nokunambitheka kwemikhiqizo, futhi ibe nempilo enhle yeshelufu.

2. Ukumelana nokubhoboza okuhle

Iqukethe izinto ezibukhali njengamathambo namathambo ezinhlanzi.Ukuze kuqinisekiswe ukuthi isikhwama asibhobozwanga, kufanele sibe nokuphikiswa okuhle kokubhoboza.

3. Ukubonakala kahle

Ungabona ngokuqondile imikhiqizo ephuma ephaketheni ukuze uhehe ukunaka kwabathengi.

4. Ukuqina okuhle

Lolu hlobo lokudla kwesilwane esifuywayo ngokuyisisekelo lupakishwe ngetheyiphu yoziphu emile, ngakho-ke impahla yokupakisha inokuqina okuhle futhi ingathuthukisa umphumela weshelufu wezimpahla.

5. Ukumelana kahle nemisebe

Ngemuva kokushiswa kwemisebe, isengakwazi ukugcina izakhiwo ezinhle zemishini.

Isibonelo sokukhetha isakhiwo

Ukuze kuhlangatshezwane nalezi zidingo ezingenhla zokupakishwa kokudla kwezilwane ezifuywayo, siphakamisa ukuthi kwamukelwe lesi sakhiwo esiyinhlanganisela esilandelayo:

Isendlalelo esimaphakathi: Ifilimu ye-BOPA noma ifilimu ye-EHA ephezulu evimbelayo enokumelana komoyampilo okuphezulu

I-BOPA inayiloni i-polyamide, enamandla amakhulu, ukuqina, amandla aqinile, ukunwebeka kanye nokumelana nokugqokwa.Inayiloni ikhethwa ngoba inezinto ezinhle zomzimba nezomshini.Ngemuva kokuhlanganiswa, ingathuthukisa ukumelana nokubhoboza, ukumelana nomthelela nezinye izakhiwo zomkhiqizo, futhi ingavikela okuqukethwe kahle.Isincomo: Changsu BOPA Ultrany.

I-EHA inokumelana komoyampilo okuphezulu kakhulu (okudluliswa komoyampilo OTR iphansi njengosuku lwe-2cc/ ㎡ · I-ATM), engafinyelela ukugcinwa kwephunga elihle kakhulu;Ukumelana kwayo nokuhlikihla, ukumelana nokuqina namandla okuhambisana okuhle kakhulu kunciphisa kakhulu izinga lokuphuka kwesikhwama;Futhi ingafinyelela ukubonakala okuphezulu kanye nomphumela omuhle kakhulu wokuphrinta;Ngaphezu kwalokho, kubuye kube yinto ehambisana nemvelo engeke ikhiqize amagesi anobuthi lapho isha.Isincomo: Ifilimu entsha yokukhiya i-Changsu Supamid EHA.

Isendlalelo sangaphakathi: Ifilimu ye-PE enefomula ethuthukisiwe

Uma kucatshangelwa ukuphepha kanye nenhlanzeko yokudla kwezilwane ezifuywayo, lo mkhiqizo usebenzisa inqubo yokukhiqiza engancibiliki.Kodwa-ke, inqubo yokukhiqiza engancibilikiyo izoba nezinkinga zokungqubuzana okuphezulu nokungavuleki kahle.Ngakho-ke, ukuze kuthuthukiswe ukuguquguquka kwemishini ye-PE, ukwakheka, ukumelana nokubhoboza kanye nokumelana nemisebe yesikhwama somzimba wesikhwama kufanele kucatshangelwe.Ifomula ye-PE ingathuthukiswa ukuze ikwazi ukuguquguquka okungcono kwemishini, ukuqina nokumelana nokubhoboza.

Inayiloni ye-BOPA yi-polyamide, enobucwebe obuqinile, indawo yokuncibilika ephezulu nokusebenza okuhle kakhulu.Ukuqina okuhle, amandla aqinile namandla okuthinta kungcono kakhulu kunefilimu yepulasitiki evamile.Njengesendlalelo esimaphakathi kule phrojekthi, ingathuthukisa ukumelana nokubhoboza kokupakishwa kwe-PET ukuvimbela izinto ezibukhali njengamathambo ezinhlanzi ekubhobozeni ifilimu.Ngaphezu kwalokho, ukuqina komoya kwenayiloni kungcono kunokwe-PE ne-PP, okungathuthukisa ukusebenza komgoqo wokupakisha.Ngesikhathi esifanayo, inokumelana okuhle nowoyela, okungamelana nebala likawoyela lapho ipakisha ukudla kwezilwane ezifuywayo kwemikhiqizo yenyama, ukuze igweme ukubola kwefilimu yokupakisha kanye nokwehla kwamandla e-peel.

Isikhathi sebhonasi sokudla kwesilwane esifuywayo sesifikile, sicela ungabe usalinda!Vumela uChangsuIfilimu ye-BOPAfuthiIfilimu ye-Supamidvikela ukudla kwezilwane ezifuywayo.
