Izikhwama ze-retort ezikwazi ukumelana nokushisa okuphezulu zinezakhiwo zokupakisha ezihlala isikhathi eside, isitoreji esizinzile, ukulwa namagciwane, ukwelashwa kokushisa okuphezulu kokushisa, njll., futhi ziyizinto ezinhle zokupakisha eziyinhlanganisela. Ngakho-ke, yiziphi izinto okufanele zinakwe mayelana nesakhiwo, ukukhethwa kwezinto ezibonakalayo, nobuciko? Umkhiqizi wokupakisha oguquguqukayo onguchwepheshe we-PACK MIC uzokutshela.
Isakhiwo nokukhethwa kwempahla yesikhwama sokubuyisela esimelana nokushisa okuphezulu
Ukuze kuhlangatshezwane nezidingo zokusebenza kwezikhwama zokuphindisela eziphikisana nokushisa okuphezulu, ungqimba lwangaphandle lwesakhiwo senziwe ngefilimu ye-polyester yamandla aphezulu, isendlalelo esiphakathi senziwe nge-aluminium foil enezakhiwo ezivikela ukukhanya nezingangeni moya, kanye nesendlalelo sangaphakathi. yenziwe ngefilimu ye-polypropylene. Isakhiwo esinezendlalelo ezintathu sihlanganisa i-PET/AL/CPP ne-PPET/PA/CPP, kanti uhlaka olunezendlalelo ezine luhlanganisa i-PET/AL/PA/CPP. Izici zokusebenza zezinhlobo ezahlukene zamafilimu zimi kanje:
1. Ifilimu kaMylar
Ifilimu ye-polyester inamandla amakhulu emishini, ukumelana nokushisa, ukumelana nokubanda, ukumelana nowoyela, ukumelana namakhemikhali, umgoqo wegesi nezinye izakhiwo. Ubukhulu bayo buyi-12um / 12microns futhi ingasetshenziswa.
2. I-aluminium foil
I-aluminium foil inomgoqo wegesi omuhle kakhulu kanye nokumelana nomswakama, ngakho-ke kubaluleke kakhulu ukulondoloza ukunambitheka kwangempela kokudla. Ukuvikelwa okuqinile, okwenza iphakheji ingathinteki kalula kumabhaktheriya kanye nesikhunta; ukuma okuzinzile emazingeni okushisa aphezulu naphansi; ukusebenza okuhle kwe-shading, ikhono eliqinile lokubonisa ukushisa nokukhanya. Ingasetshenziswa ngobukhulu obungu-7 μm, ibe nezimbobo ezimbalwa ngangokunokwenzeka, futhi imbobo encane ngangokunokwenzeka. Ngaphezu kwalokho, ukucaba kwayo kufanele kube kuhle, futhi indawo engaphezulu kufanele ingabi namabala amafutha. Ngokuvamile, ama-aluminium foil asekhaya awakwazi ukuhlangabezana nezidingo. Abakhiqizi abaningi bakhetha umkhiqizo we-aluminium foil waseKorea naseJapane.
3. Inayiloni
Inayiloni ayigcini nje ngokuba nezinto ezinhle zokuvimbela, kodwa futhi ayinaphunga, ayinambitheki, ayinabuthi, futhi ayizwani nokubhoboza. Inobuthakathaka bokuthi ayimelani nomswakama, ngakho kufanele igcinwe endaweni eyomile. Uma isimunca amanzi, izinkomba zayo ezihlukahlukene zokusebenza zizokwehla. Ugqinsi lwenayiloni luyi-15um(15microns) Ingasetshenziswa ngokushesha. Uma u-laminating, kungcono ukusebenzisa ifilimu ephethwe kabili emaceleni. Uma kungeyona ifilimu ephathwayo ezinhlangothini ezimbili, uhlangothi lwayo olunganakiwe kufanele lufakwe nge-aluminium foil ukuze kuqinisekiswe ukushesha okuyinhlanganisela.
4.I-Polypropylene
Ifilimu ye-polypropylene, ungqimba lwangaphakathi lwezikhwama zokumelana nokushisa okuphezulu, ayidingi nje kuphela ukugcwala okuhle, kodwa futhi inezidingo eziqinile kumandla ayo aqinile, amandla okufaka uphawu okushisa, amandla omthelela kanye nokwelula ngesikhathi sekhefu. Imikhiqizo yasekhaya embalwa kuphela engahlangabezana nezidingo. Iyasetshenziswa, kodwa umphumela awumuhle njengezinto zokusetshenziswa eziphuma kwamanye amazwe, ukujiya kwayo kungama-60-90microns, futhi inani lokwelapha elingaphezulu lingaphezu kwama-40dyn.
Ukuze uqinisekise kangcono ukuphepha kokudla ezikhwameni ezinezinga lokushisa eliphezulu, ukupakishwa kwe-PACK MIC kukwethulela izindlela ezi-5 zokuhlola ukupakishwa kwakho lapha:
1. Isikhwama sokupakisha sokuhlola ukungangeni moya
Ngokusebenzisa ukuvunguza komoya ocindezelwe kanye nokukhishwa kwamanzi ngaphansi kwamanzi ukuhlola ukusebenza kokuvalwa kwezinto, ukusebenza kokuvalwa kwezikhwama zokupakisha kungaqhathaniswa ngokuphumelelayo futhi kuhlolwe ngokuhlolwa, okunikeza isisekelo sokunquma izinkomba zobuchwepheshe zokukhiqiza ezifanele.
2. Isikhwama sokupakisha ukumelana nokucindezela, ukusebenza kokumelana nokwehlatest.
Ngokuhlola ukumelana nokucindezela kanye nokusebenza kokumelana nokwehla kwesikhwama sokubuyisela izinga lokushisa eliphezulu, ukusebenza kokumelana nokuqhekeka kanye nesilinganiso ngesikhathi senqubo yokubuyisela kungalawulwa. Ngenxa yesimo esishintsha njalo enqubweni yokwenza inzuzo, ukuhlolwa kwengcindezi yephakheji elilodwa kanye nokuhlolwa kokuwa kwebhokisi lonke lemikhiqizo kuyenziwa, futhi ukuhlolwa okuningi kwenziwa ngezindlela ezihlukene, ukuze kuhlaziywe ngokuphelele ingcindezi. futhi yehlise ukusebenza kwemikhiqizo epakishiwe futhi kuxazululwe inkinga yokwehluleka komkhiqizo. Izinkinga ezidalwe ukupakishwa okulimele ngesikhathi sokuthutha noma sokuthutha.
3. Ukuhlolwa kwamandla omshini wezikhwama zokushisa eziphakeme zokushisa
Amandla okusebenza wento yokupakisha ahlanganisa amandla ayinhlanganisela axebukayo wento, amandla okuvala ukushisa okuvalwa, amandla aqinile, njll. Uma inkomba yokuthola ingakwazi ukuhlangabezana nezinga elijwayelekile, kulula ukuphuka noma ukuphuka phakathi nenqubo yokupakisha neyokuthutha. . I-universal tensile tester ingasetshenziswa ngokuya ngamazinga afanele kazwelonke nawemboni. kanye nezindlela ezijwayelekile zokuthola nokunquma ukuthi ifanelekile noma cha.
4. Ukuhlolwa kokusebenza kwesithiyo
Izikhwama ezikwazi ukumelana nokushisa okuphezulu ngokuvamile zigcwele okuqukethwe okunomsoco njengemikhiqizo yenyama, ekhishwa kalula nge-oxid futhi yonakale. Ngisho nangaphakathi kwempilo yeshalofu, ukunambitheka kwabo kuzohluka ngezinsuku ezihlukene. Ngekhwalithi, izinto zokuvimbela kufanele zisetshenziswe, ngakho-ke ukuhlolwa okuqinile kwe-oxygen kanye nomswakama kufanele kwenziwe ezintweni zokupakisha.
5. Ukutholwa kwe-solvent eyinsalela
Njengoba ukuphrinta nokuhlanganiswa kuyizinqubo ezimbili ezibaluleke kakhulu ekukhiqizeni ukupheka kokushisa okuphezulu, ukusetshenziswa kwe-solvent kuyadingeka ekunyatheliseni nasekuhlanganiseni. I-solvent iyikhemikhali ye-polymer enephunga elithile elihlabayo futhi iyingozi emzimbeni womuntu. Izinto zokwakha, imithetho yangaphandle kanye nemithethonqubo inezinkomba zokulawula eziqine kakhulu kwezinye izincibilikisi ezifana ne-toluene butanone, ngakho-ke izinsalela ze-solvent kufanele zibonwe ngesikhathi sokukhiqizwa kokuphrinta imikhiqizo eqediwe, imikhiqizo eyinhlanganisela eqediwe kanye nemikhiqizo eqediwe ukuze kuqinisekiswe ukuthi imikhiqizo inempilo futhi iphephile.
