PVC ata tifaga vasega,
PVC mo ata tifaga, PVC resin mo Flexible Vinyl Film, PVC resin mo Rigid Vinyl Film,

PVC ata tifaga e aunoa ma plasticizer ua taʻua vinyl malo maaa, ae plasticized PVC ua taʻua flexible vinyl ata tifaga.
1.Flexible Vinyl Ata Ata

O ata vinyl fe'avea'i e iai mea fa'alava lelei i le suau'u ma le ga'o ae e mafai ona fa'amalieina le okesene.E lelei fo'i le pipi'i, lelei le manino ma le tu'i.O nei meatotino e mafai ai ona fetu'una'i le PVC mo le afifiina o mea'ai e teu ai aano o manufasi ma isi mea e pala (pe a talia e le FDA).Ae ui i lea, o le PVC palasitika o loʻo i ai se mea faʻafefeteina maualalo, e faʻaitiitia le faʻafefe i vailaʻau, ma e maualalo lona malosi malosi nai lo vinyl malo.

2. Ata Vinyl Malosi

Rigid vinyl, e ta'ua fo'i o le unplasticized polyvinyl chloride (uPVC), ose ata malosi ma mama.O se tasi lea o ata e sili ona umi e taugofie ma e tetee i le tele o vailaʻau.E masani lava, e mafai ona fa'aogaina le uPVC i le vevela e o'o atu i le 60°C.E maualuga atu le malosi ma le modulus nai lo le PVC fetuutuunai, ae e maualalo le a'afiaga o le malosi, ma e mafai ona faʻalavelave faʻalagolago i le siosiomaga.

O le PVC e iai ni tapula'a ma fa'aletonu;o le plasticizer e mafai ona faʻamaʻaʻa i tulaga malulu ma faʻamalulu i lalo o tulaga vevela, lea e oʻo atu ai i se suiga i meatotino ma mafai ona faʻafefeteina le malosi o le faʻamaufaʻailoga.O le PVC foi na te faʻasaʻolotoina ni vaega laiti ole hydrogen chloride i le ea ma maua ai le kaponi i luga o mea faʻamaufaʻailoga pe a vevela.Mo lenei mafuaʻaga, e manaʻomia le faʻaleleia lelei o le ea pe a faʻamaufaʻailogaina le PVC shrink-wrap.

TALOSAGA
O le ata PVC e faʻaaogaina e pei o le faʻaitiitia ma le faʻalauteleina o afifi mo mea tau pisinisi ma oloa faʻatau ma faʻapipiʻi pallet, peitaʻi, i se fua laʻititi nai lo ata polyolefin.O isi fa'aoga e aofia ai ato, liner, atigi fagu, fa'apipi'i fa'amau, fa'ailoga, taga toto ma taga IV.E masani ona ufiufi PVDC pe a manaʻomia le faʻaleleia atili o mea e puipuia ai le susu.

FDA faamaonia PVC o se filifiliga lelei e afifi aano fou mumu aua e semi-permeable, o lona uiga, naʻo le lava o le okesene faʻafefete e tausia ai aano o manufasi fou ma faatumauina lona lanu mumu susulu.A taua le manino, e masani ona faʻaaogaina le PVC.

O le Polyvinyl Chloride, e taʻua o le PVC, o se tasi o ituaiga palasitika gaosi oloa, o le gaosiga o loʻo i ai nei e lona lua i le polyethylene.Polyvinyl chloride ua faʻaaogaina lautele i alamanuia, faʻatoʻaga ma le olaga i aso uma.O le Polyvinyl chloride o se polymer compound polymerized e vinyl chloride.E vevela.Pa'epa'e po'o le pa'epa'e samasama malamalama. E solu i ketones, esters, tetrahydrofurans ma chlorinated hydrocarbons.Fa'agata fa'ama'i sili.Le lelei le mautu vevela ma le malamalama tetee, sili atu i le 100 ℃ poʻo le umi o le faʻaalia i le susulu o le la na amata ona faʻaleagaina le hydrogen chloride, e manaʻomia e le gaosiga o palasitika le faʻamautu.E lelei le insulation eletise, e le mu.

O le Vasega S-700 e masani ona faʻaaogaina e gaosia ai ni paʻu manino, ma e mafai ona oomiina i se fasi pepa malo poʻo semi-malosi poʻo se laupepa mo afifi, mea fola, ata tifaga mo le ufiufi (mo lole afifi pepa poʻo sikaleti ata tifaga), ma isi. fa'apea fo'i ona tu'u i luga o se fasi pepa malo pe semi-malosi, pepa, po'o se pa e le masani ona fa'atusa mo afifi.Pe mafai foi ona tui e fai sooga, valve, vaega eletise, mea faʻaoga taavale ma vaʻa.
