I se tulaga lautele, o le totonu o totonu ma fafo o ata puʻe o ata puʻe o mea taʻitasi ma meatotino, fausia le faʻagaioiga, ma le vevela faʻapipiʻi vaega. E manaʻomia foʻi le i ai o le lelei o le vevela o le faʻatinoina tapenapegaga o faʻatinoga ma le lelei o le tau, e tele sona taugofie ma le ono mafai ona oʻo i le tulaga sili ona lelei o le ata puʻe. O mea faʻavae e masani tele, irp, Eva, Pet, ma PS.
Mea aoga
Le vaega galue oMeaʻai meaʻaie tele o se pa puipui, e masani lava i le ogatotonu o le tele-stoor compiasite ata tifaga, e masani ona ofi i luga o le BOOHH, PHDS,
Evoh (Ethylene Voyl Brevel Botalymer)
Ethylene Voyll Brevel Botanemer o se polymer mea e tuʻufaʻatasia ai le faʻagasologa o le Ethyle o Ethylemen ma le kesi paoa o le ethyne o Ethleyne o Ethleyne; E manino lava ma ei ai le manaia gloss. EVOH has excellent barrier properties for gases and oils, with excellent mechanical strength, elasticity, wear resistance, cold resistance, and surface strength, and excellent processing performance. O le papupuni o le evoh e faʻalagolago i le ethylene mea. A tele mea e faʻaitiitia ai le Ethanone, ae o loʻo faʻaitiitia lava le kesi kesi, peitaʻi o le susuna saʻo lea e siʻitia le faʻatinoga, ma e faigofie lava ona faʻagaioi.
Oloa afifiina ma evhh mea e aofia ai vaitau, o oloa susu, oloa oloa, cheese oloa, ma isi mea
PVDC (Polyvinylsidenene Chloride)
Polyvinylsidenene Chloride (PVDC) o se polymer o le vinylidel chloride (1,1-dichlorothylene). O le le mautonu o le vevela o Homopolymer PVDC e maualalo ifo nai lo lona liusuavai manatu, faigata ona liusuavai. O le mea lea, e pei ona faʻatupeina ni mea, pvDC o se leoleo o le tele o le fale talimalo o le viny faloso ma viniking
I le amataga o aso, sa faʻaaoga tele mo le faʻatau atu o le militeli. I le 1950, sa amata na faʻaaogaina e avea o se meaai faʻasao, aemaise lava o le atinaʻeina o le ola faaonapo nei, ma le faʻavaveina o meaʻai ma fualaau faasaina. O le PVDC e mafai ona faia i Ultra-manifinifi ata tifaga, faʻaititia le aofaʻi o mea mata ma afifiina tau. O loo lauiloa lava i aso nei
Mea e teu ai
Ona o le mativa e le lelei i le va o le faʻavae o loʻo resids ma le faʻaaogaina o le mea e mafai ona tuʻu ai ni mea faʻapitoa i le va o nei lua vaega. O le mea faʻapipiʻi o loʻo faʻaaogaina le faʻapipiʻiina o le faʻapipiʻi, masani ona faʻaaoga e aofia ai polyolefin faʻapipiʻi ma le anic ayhydride copitiona copolyl copothyl copothyl coponymer (eva).
Manic ayhydride palu polyolefins
O le tane o le anic ayhydride o le polyolefin e faia e ala i le faʻapipiʻiina o le mayhydride i luga o polythylene e ala i le toe faia o le auala i luga o laina e leai ni mea. O se mea faʻapipiʻi i le va o le pole ma le le-poleti o mea ma e masani ona faʻaaogaina i totonu o ata tifaga o polyolefins e pei o le polycropylene ma nylon.
Eva (ethylene vinyl acetate copolymer)
Ua faʻailoa e Eva Vinyl Acetate Fonamer i le Molecular Chan, Faʻaititia le Cystaltalinical o Polythylene ma faʻaleleia o le le mautonu ma le vevela ma le fofoina o le mata. O vaega eseese o Ethylene ma Vinyl Actate i mea e mafua mai i ni talosaga eseese:
① O mea autu o Eva ma Ethylene Actitate anotusi o loʻo i lalo ifo o le 5% o iniseti, ata tifaga, uaea ma uaea, etc;
② O oloa autu o Eva ma le vinyl acetate mataupu o le 5% ~ 10% o ni ata tifaga mama, isi;
③ O oloa autu a e Eva ma se vinyl acetate mataupu o le 20% ~ 28% o le vevela o le filble fulfutisi ma tausaa oloa;
④ O mea autu o Eva ma le Vinyl Actate mataupu o le 5% ~ 45% o ata tifaga (aofia ai ata tifaga) ma ie, tui o oloa, frem oloa, ma isi mea
