1, folasaga ata tifaga polyester

Polyester ata tifaga ua taʻua foi polyester ata tifaga (PET) (ata mama, polyester ata tifaga, pepa maaleale, polyester ata tifaga, benzene tin ata, cellophane, tatala ata tifaga), o se polyethylene terephthalate e pei o mea mata, le faaaogaina o auala extrusion i ata mafiafia, ona sosoo ai lea ma le fa'ava'a fa'alua e faia i mea ata tifaga.

Ata polyester fale (polyester ata tifaga, siosiomaga puipuiga ata tifaga, PET ata tifaga, opal ata ma isi lomitusi ma afifi consumables), faʻaaogaina lautele i fibre tioata faʻamalosia alamanuia palasitika, alamanuia mea fau fale, fale lomitusi, vailaʻau ma le soifua maloloina.

I le taimi nei, ua manuia le atinaʻeina e Saina o se PET twist film, e le oona, e leai se lanu, manino, susu, manava, vaivai, malosi, gaʻo acid-alkali ma solvent, ma e le fefe i le maualuga ma le maualalo o le vevela.O se mea e le oona, manino toe faʻaaogaina, e masani ona faʻaaogaina i le tele o meainu, vai minerale ma afifi ata tifaga, o loʻo faʻaaogaina nei i le lalolagi o se tasi o mea faʻapipiʻi.

O le ata o le Mylar o se ituaiga polymer plastic film, ona o lona tulaga lelei atoatoa ma sili atu ona fiafia i ai le tele o tagata faʻatau.Ona o le gaosiga o Saina ma tulaga faʻapitoa e le mafai ona faʻafetaui manaʻoga o le maketi, o nisi e manaʻomia pea ona faʻalagolago i oloa mai fafo.

2, meatotino ata tifaga polyester

PET o se polymer maualuga, e mafua mai i le condensation dehydration o le ethylene terephthalate.Glycol terephthalate e maua i le esterification o le terephthalic acid ma glycol.PET ose susu papa'e po'o moli samasama, sili tioata tioata ma se lamolemole, iila luga.

PET o loʻo i ai mea sili ona lelei (teteʻe vevela, faʻamaʻi vailaʻau).Malosi ma faigata, faʻapipiʻi eletise, saogalemu, ma isi), taugofie, faʻaaogaina lautele e pei o fiber, ata tifaga, faʻainisinia palasitika, fagu polyester ma isi.

PET o loʻo i ai mea faʻapitoa faʻaletino ma masini i le lautele o le vevela, faʻaaogaina umi le vevela e oʻo atu i le 120 ℃, faʻaogaina lelei eletise, e oʻo lava i le maualuga o le vevela ma le tele o taimi, o loʻo lelei pea ona eletise, ae le lelei le faʻaogaina o le corona, anti-toxic , tete'e tau, mautu tete'e vaila'au, fetolofi, tete'e vaivai, tete'e fe'ese'esega, tulaga mautu e matua lelei.E maualalo le vai, tete'e i vai vaivai ma solvents organic, ae le o le vevela e tetee i le faatofuina o le vai, ae le o le alkali tetee.

E masani lava o le PET e leai se lanu manino, ata tifaga iila (e mafai nei ona faʻaopopo mea faʻaopoopo ina ia maua ai le lanu), mea faʻainisinia sili ona lelei, maualuga maualuga, maʻaʻa ma faigata, puncture resistance, friction resistance, maualuga le vevela ma le maualalo o le vevela, vailaʻau faʻamaʻi, suauʻu. tete'e, ea tightness ma le manogi faasao, o se tasi o mea e masani ona faaaogaina anti-penetration composite film substrates, ae o le corona tetee e le lelei.
