Ukusetyenziswa kwefilimu yenylon kwipakethe yokutya kwesilwanyana

Kumazwe asentshona, "uqoqosho lwezilwanyana" lishishini elikhulu.Ukuthatha ukutya kwesilwanyana njengomzekelo, uMntla Melika (ikakhulukazi eUnited States) yeyona marike inkulu yabathengi kuko konke ukutya kwesilwanyana, kwaye ikwabala uninzi lwentengiso.Intshona Yurophu yeyona ndawo iphambili kwintengiso yabathengi kuzo zonke ezinye iindidi zokutya kwezilwanyana zasekhaya, kunye neyesibini ngobukhulu intengiso yabathengi yokutya kwenja kunye neekati.Phakathi kwabo, uphuhliso loqoqosho lwezilwanyana ezifuywayo e-United States naseJapan lubalaseleyo.

Iingxaki ezinokuthi zenzeke kwimeko yemarike yangoku

ETshayina, baya besanda abantu abanezilwanyana zasekhaya.Ngokunyuka kwenani lezilwanyana zasekhaya, uthotho lwemizi-mveliso enxulumeneyo luye lwavela kuqoqosho lwezilwanyana zasekhaya, njengokutya kwezilwanyana zasekhaya, ukubonelela ngezilwanyana zasekhaya, unyango lwezilwanyana zasekhaya, ishishini lobuhle bezilwanyana zasekhaya, njl., eliya kuba nethemba elibanzi lemarike.Ukupakishwa kokutya kwesilwanyana kuya kuba yenye yeendawo ezishushu kwintsimi yokupakisha kwixesha elizayo.

Ukuthatha ukutya kwezilwanyana ezifuywayo okufana neekati nezinja njengomzekelo, imathiriyeli ekrwada ikakhulu ziimveliso zenyama.

Iimpawu zayo ziquka le miba mibini ilandelayo:

1. Ukuze kugcinwe incasa yokutya kwesilwanyana, izithako akufanele zenziwe zithambile kakhulu okanye zibe powdery ngexesha lenkqubo yokuvelisa.Kuyimfuneko ukugcina ukuqina kunye ne-brittleness yenyama, amathambo kunye namathambo eentlanzi.Ngoko ke, ukutya kwezilwanyana ezifuywayo kubonakala ngokungaqhelekanga kwaye kuqulethe izinto ezibukhali ezifana namathambo kunye namathambo eentlanzi.

2. Ukutya kwezilwanyana ezifuywayo kukutya okufakwe kwi-irradiated.Ukwandisa ubomi beshelufu, ukutya kwezilwanyana zasekhaya kufuneka kufakwe iradiation ukuze kubulawe inzala.Ukutya okufakwe kwi-irradiated kubhekiselele kukutya okucutshungulwayo ngokufakwa kwimitha ye-gamma eveliswe yi-cobalt-60 kunye ne-cesium-137 okanye imiqadi ye-electron engaphantsi kwe-10MeV eveliswa yi-electron accelerators, kubandakanywa izinto ezikrwada zokutya kunye neemveliso ezigqityiweyo.

Okwangoku, iteknoloji ye-irradiation isetyenziswa kakhulu kumazwe amaninzi ukuqinisekisa ukhuseleko lokutya kunye nokwandisa ubomi beshelufu yokutya, kwaye ibonwa ngabathengi abaninzi nangakumbi.Njengefriji yobushushu obuphantsi, unyango oluphezulu kunye nokunyangwa kweekhemikhali, le teknoloji inokususa i-microorganisms. ezibangela urhwaphilizo lokutya kunye nezifo ezibangelwa kukutya kwi-food.In yokutya, i-radiation yindlela enhle yokwandisa ubomi beshelufu yokutya.

Kwiinkqubo zokupakishwa kwe-aseptic, iindlela zokuvala inzalo yezinto zokupakisha zibandakanya ukutshatyalaliswa kwe-ultraviolet, iindlela zekhemikhali kunye ne-ultraviolet inzalo edibeneyo, inzalo ye-infrared, i-ionizing radiation kunye ne-pulses ekhanyayo.Xa imathiriyeli yokupakisha ingenako ukudlula amandla obushushu okanye idlule kwimitha ye-Ionizing yindlela efanelekileyo yokuvala inzala ebandayo yokubulala iintsholongwane kunye nokubulala iintsholongwane.

Okwangoku, ukupakishwa kwesilwanyana esiqhelekileyo kwimarike yaseTshayina kwamkela ngokubanzi indlela yokupakisha yebhegi ene-zipper ene-dimensional.Ukuze kuphuculwe isiphumo seshelufu kunye nokusebenza komqobo, uninzi lwabavelisi bokupakisha abaguquguqukayo basekhaya basebenzisa i-VMPT okanye i-AL njengoluhlu lwesithintelo;

Iingxaki zokupakishwa kokutya kwesilwanyana saseTshayina zibandakanya le miba ilandelayo:

1. I-VMPET okanye i-Al isetyenziswe njengoluhlu lwesithintelo, kodwa iimveliso azikwazi ukubonwa ngokuthe ngqo, ezikhawulela i-shelf display effect yeemveliso;

2 Njengoko iimveliso zingamathambo, amathambo eentlanzi kunye nezinye izinto, isikhwama kulula ukugqobhoza, okubangela iingxaki zomgangatho.

3 Ukuguda kwengxowa yokupakisha akulunganga, kwaye ukuvulwa kubi kwinkqubo yokuvelisa, kwaye ukusebenza kakuhle kwemveliso kuphantsi.Ngexesha elifanayo, kuya kunciphisa izinga lokusetyenziswa kwengxowa yokupakisha kunye nokunyusa iindleko.

4 Emva kokukhanya kwemitha, iipropathi zomatshini ezipheleleyo zebhegi zehla.

Ingcamango yokuyila yesakhiwo esiyintlanganisela sokupakishwa kokutya kwesilwanyana sasekhaya

Kwimveliso yangempela, i-irradiation ayinayo impembelelo kwiipropati zeglasi kunye nezikhongozeli zetsimbi, kodwa inokunciphisa ukuguquguquka kunye neempawu zomatshini zeplastiki.Ngoko ke, kwinkqubo yokuyila, ukuba akukho sakhiwo esifanelekileyo esidibeneyo, isikhwama silula ukuhlatywa kunye neempawu ezibonakalayo kunye nezobugcisa zesikhwama ziyancipha.Ngoko ke, kubaluleke kakhulu ukufundisisa isakhiwo esisodwa esidibeneyo ukulungelelanisa impembelelo yokukhanya kwiipropati zeplastiki.

Ukupakishwa kokutya kwesilwanyana sasekhaya kufuneka kuhlangabezane nezi mfuno zilandelayo ngexesha lokupakishwa, ukuthutha, ukugcinwa kunye nokusetyenziswa:

1. Ukusebenza kakuhle komqobo

Iimveliso zepakethe kukutya kwezilwanyana, ekufuneka zikwazi ukuhlangabezana neemfuno zoqinisekiso lomgangatho weemveliso, zigcine umgangatho kunye nencasa yeemveliso, kwaye zibe neshelufu elungileyo.

2. Ukumelana kakuhle nokugqobhoza

Iqulethe izinto ezibukhali ezifana namathambo kunye namathambo entlanzi.Ukuqinisekisa ukuba ibhegi ayigqojozwanga, kufuneka ibe nokumelana nokugqobhoza okulungileyo.

3. Ukubonakala kakuhle

Ungabona ngokuthe ngqo iimveliso ezivela kwiphakheji ukutsala ingqalelo yabathengi.

4. Ukuqina okulungileyo

Olu hlobo lokutya kwesilwanyana sasekhaya lupakishwe ngeteyiphu ye-zipper emileyo, ngoko ke imathiriyeli yokupakisha inokuqina okuhle kwaye inokuphucula isiphumo seshelufu sempahla.

5. Ukumelana nemitha elungileyo

Emva kokukhanya, iyakwazi ukugcina iimpawu ezintle zoomatshini.

Umzekelo wokukhethwa kwesakhiwo

Ukuze kuhlangatyezwane nezi mfuno zingasentla zokupakishwa kokutya kwesilwanyana sasekhaya, sicebisa ukuba olu lwakhiwo lulandelayo lunokwakhiwa:

Umaleko ophakathi: ifilimu yeBOPA okanye ifilimu ye-EHA ephezulu yesithintelo enokumelana neoksijini ephezulu

Inayiloni ye-BOPA yi-polyamide, enamandla abalaseleyo, ukuqina, ukomelela, ukomelela kunye nokumelana nokunxiba.Inayiloni ikhethiwe kuba ineempawu ezintle zomzimba kunye nezomatshini.Emva kokudibanisa, inokuphucula ukuxhathisa kwe-puncture, ukuchasana kwempembelelo kunye nezinye iimpawu zemveliso, kwaye inokukhusela imixholo kakuhle.Ingcebiso: Changsu BOPA Ultrany.

I-EHA inokumelana ne-oxygen ephezulu kakhulu (i-oxygen transmittance OTR iphantsi njenge-2cc/ ㎡ imini · i-ATM), enokufikelela ekugcineni ivumba elimnandi;Ukuxhathisa kwayo, ukuxhathisa kunye namandla okuthotyelwa okugqwesileyo kunciphisa kakhulu izinga lokuqhekeka kwengxowa;Kwaye inokufikelela elubala okuphezulu kunye nesiphumo esihle kakhulu sokushicilela;Ukongeza, ikwayinto ehambelana nokusingqongileyo engayi kuvelisa iigesi ezinobuthi xa itshiswa.Ingcebiso: Changsu Supamid EHA ifilimu yokutshixa entsha.

Uluhlu lwangaphakathi: Ifilimu ye-PE enefomula ephuculweyo

Ukuqwalasela ukhuseleko kunye nococeko lokutya kwesilwanyana, le mveliso ithatha inkqubo yokuvelisa i-solvent-free.Nangona kunjalo, inkqubo yokuvelisa i-solvent-free iya kuba neengxaki ze-friction coefficient ephezulu kunye nokuvuleleka okubi.Ke ngoko, ukuze kuphuculwe ukuguquguquka kwezixhobo ze-PE, ukubumbeka, ukuchasana nokugqabhuka kunye nokumelana nemitha yengxowa yomzimba kufuneka kuqwalaselwe.Ifomula ye-PE inokuphuculwa ukuze ibe nokuguquguquka okungcono kwezixhobo, ukuqina kunye nokumelana nokugqobhoza.

I-BOPA inayiloni yi-polyamide, ene-crystallinity eyomeleleyo, indawo ephezulu yokunyibilika kunye nokusebenza okugqwesileyo.Ukuqina okuhle, ukomelela kunye namandla empembelelo angcono kakhulu kunefilimu yeplastiki eqhelekileyo.Njengomaleko ophakathi kule projekthi, inokuphucula ukunganyangeki kokupakishwa kwePET ukuthintela izinto ezibukhali ezinje ngamathambo eentlanzi ekubhobhozeni ifilimu.Ngaphezu koko, ukuqina komoya kwenylon kungcono kune-PE kunye ne-PP, enokuphucula ukusebenza komqobo wokupakisha.Kwangaxeshanye, inokumelana ne-oyile elungileyo, enokumelana ne-oyile xa ipakisha ukutya kwesilwanyana semveliso yenyama, ukuze kuthintelwe ukubola kwefilimu yokupakisha kunye nokuncipha kwamandla e-peel.

Ixesha lebhonasi lokutya kwesilwanyana sasekhaya lifikile, nceda ungalindi kwakhona!Makhe uChangsuIfilimu ye-BOPAkwayeIfilimu yeSupamidkhusela ukutya kwesilwanyana.
