O se mea fa'apipi'i manino fa'atasi ai ma mea e sili ona maualuga pa puipui na atia'e i le 1980s, lea e ta'ua fo'i o le sima fa'apipi'i.
5. Kelu (mamago/susū) ata fa'apipi'i
O ata Monolayer e iai ni fa'amanuiaga fa'apitoa ma fa'aletonu.Metotia o ata fa'asusu susu: e fa'apipi'i le tasi mea'ai i le kelu ona fa'apipi'i lea i le isi ata, ona fa'amamago ma fa'amalolo.Afai o se mea e le porous, o le kelu faʻamago atonu e le lelei ma o le a faʻaitiitia le lelei o le membrane tuʻufaʻatasia.Metotia lamination mago: Faʻapipiʻi le mea faʻapipiʻi i luga o le mea faʻapipiʻi, faʻamago muamua le faʻapipiʻi, ona oomi lea ma faʻapipiʻi e faʻapipiʻi ata o mea eseese.
6. Extrusion faʻapipiʻiina ata faʻapipiʻi
I luga o se extruder, e lafoina le thermoplastic i se T-die i luga o le pepa, pepa, pepa palasitika e faʻapipiʻiina, poʻo le resin extruded e faʻaaogaina e avea o se mea faʻapipiʻi vavalalata, ma o le isi mea faʻapipiʻi ata e vevela.O mea e fa'apipi'i fa'atasi e fai ai se ata tu'ufa'atasia o le "sani."
7. Coextrusion tu'ufa'atasi ata tifaga
Fa'aaogaina o mea fa'apipi'i se lua pe tolu, fa'asoa se pa'u tu'ufa'atasi, fa'apipi'i i le va o ni fa'ama'i fa'ama'i e maua ai ata fa'apipi'i tele po'o laupepa.
8. Ata maualuga pa puipui
Faʻasino i se mea e iai le mafiafia o le 25.4μm i lalo o le tulaga o le 23 ° C ma le RH65%, o le fua faatatau o le okesene o loʻo i lalo ole 5ml / m.2·o, ma o le fua faatatau o le susu e i lalo ole 2g/m2·o.
9. Ata fou-tausia ma sterilization
Ethylene kasa adsorption membrane, faaopoopo zeolite, cristobalite, silica ma isi mea i le membrane e mafai ona mitiia le kasa ethylene exhaled e fualaau aina ma fualaau faisua ma taofia lo latou matua vave.
Anti-condensation ma fogging ata, o le pito i totonu o le afifiina ata o fua lanu meamata e sili atu le condensation ma fogging, lea e faigofie ona mafua ai le pala i luga o meaai.
Antibacterial ata tifaga, faʻaopoopo zeolite synthetic (SiO2+ Al2O3) fa'atasi ai ma galuega fa'afesuia'i i mea palasitika, ona fa'aopoopo lea o mea fa'apipi'i fa'amasani o lo'o i ai ion siliva, fa'afesuia'i ion siliva e avea ma zeolite siliva, ma o lona pito e iai ni mea fa'ama'i.
O le mamao-infrared fou-tausia ata e faʻafefiloi ma se sima faʻatumu i totonu o le palasitika ata, ina ia i ai i le ata le galuega o le faʻatupuina o ave mamao-infrared, lea e le gata e mafai ona faʻamaʻaina, ae faʻagaoioia foi sela i le fua lanumeamata, o lea. e iai le galuega o le fa'asaoina o le fou.
10. Ata afifi aseptic
E masani ona faʻaaogaina i le gaosiga o afifi aseptic o meaʻai ma vailaʻau, e manaʻomia le iai: faʻamaʻi faʻamaʻi;tulaga maualuga ma le malosi;lelei le vevela ma le malulu (-20 ℃ e le pala);tete'e tu'i nila ma tete'e lelei punou;O le mamanu lolomi o le a le faaleagaina i le vevela maualuga sterilization po o isi auala sterilization.
11. Ato kuka e tete'e le vevela maualuga
I le 1960s, o le US Naval Research Institute muamua na atiina ae ma faʻaaogaina i meaʻai aerospace.Ina ua uma lena, sa vave ona faalauiloa e Iapani ma atiina ae ma faaaoga i ituaiga eseese o meaai faigofie.E mafai ona vaevaeina taga kuka vevela maualuga i ituaiga manino (faʻatasi ai ma se fata ola e sili atu ma le tasi le tausaga) ma le le faʻamalamalamaina (faʻatasi ai ma le ola faʻaola e sili atu ma le lua tausaga), ituaiga paʻu maualuga ma ituaiga masani.E tusa ai ma le vevela vevela, ua vaevaeina i le pusa kuka vevela maualalo (100 ℃, 30min), taga kuka vevela vevela (121 ℃, 30min), pusa kuka vevela maualuga (135 ℃, 30min).O le vaega pito i totonu o le ato tali e faia i ata eseese PE (LDPE, HDPE, MPE), faʻafefeteina maualuga le CPP poʻo le IPP faʻateleina, ma isi.
O mea lelei autu o taga kuka vevela maualuga:
①O le kukaina o le vevela maualuga e mafai ona fasiotia uma siama, 121 ℃ / 30min e mafai ona fasiotia uma siama botulinum;
②E mafai ona teuina i le vevela o le potu mo se taimi umi e aunoa ma se pusaaisa, ma e mafai ona 'ai malulu pe mafanafana;
③ O mea faʻapipiʻi e iai mea lelei puipui, e le itiiti ifo nai lo meaʻai tuʻuina;
④Liga lolomi, lolomi matagofie ma teuteuga;
⑤ E faigofie ona susunuina otaota.
12. Ata fa'apipi'i vevela maualuga
O le mea faʻafefeteina o mea e sili atu i luga ole 200 ° C, lea e fetaui lelei mo pusa faʻamalosi / vaivai.
13. Ata palasitika fa'aleagaina
E mafai ona vaevaeina oloa palasitika faʻaleagaina i le photodegradation, biodegradation, photodegradation ma le biodegradation e tusa ai ma le faʻaogaina o masini.
14. Ata fa'afefete vevela
O meafaitino o le PP, PVC, LDPE, PER, nylon, ma isi. Muamua faʻamalo le ata, i se vevela i luga aʻe o le vevela faʻamalulu (tulaga suiga tioata) ma lalo ifo o le vevela o le liusuavai, i se tulaga maualuga tele, faʻaoga le synchronous poʻo le lua-laasaga. mafolafola-mate auala fa'aloloa, po'o le calendering metotia, po'o le solvent O le faiga lafo fa'atino fa'a'ala'au fa'alautele, ma o le molelale fa'aloloa e fa'amalieina i lalo o le tulaga suiga tioata ma loka.
