PVC resini
E 4 ituaiga o PVC Resin fa'avasegaina ile auala polymerization
1. Fa'amalologa Vasega PVC
2. Emulsion Vasega PVC
3. Tele Polymerised PVC
4. Copolymer PVC
Fa'amalologa Vasega PVC
O le ituaiga sili ona taatele, Suspension grade PVC e faia i le polymerizing droplets o le Vinyl Chloride monomer o loʻo taofia i le vai.A maeʻa le Polymerization, e faʻamalo le slurry ma faʻamago malie le keke PVC e ala i faiga faʻavevela faʻapitoa ina ia aua neʻi oʻo i lalo le resini le faʻamautu i le vevela vevela.Ole lapo'a o le resini e amata mai ile 50-250 microns ma o lo'o i ai popcorn e pei o fausaga e faigofie ona mitiia le Plasticisers.O le fausaga o vaega o le PVC e mafai ona suia e ala i le filifilia o sui faʻamalolo talafeagai ma le Polymerisation Catalyst.O ituaiga porous laiti e fa'aaogaina tele mo le maualuga maualuga Rigid or Unplasticised PVC talosaga e pei o PVC Pipes, Windows, Sidings, Ductings.Suspension grades of a coarser particle size and very porous structures mitigo the large quantity of Plasticiser forming a dryblend i le vevela e maualalo ifo i le 80oC.The more porous types is used in Plasticised applications like Cables, Footwear, Soft Calendered Sheeting and Films etc.
Emulsion Vasega PVC
Emulsion Polymerised PVC o le mea lea o le Paste Grade Resin ma e toetoe lava faʻaaogaina mo Plastisols.Paste grade resin o se PVC lapopo'a sili ona lelei e gaosia e ala i le fa'amagoina o se Emulsion o le PVC i le Suavai e pei lava o le auala e gaosia ai le susu susu.E mana'omia tele le malosi e gaosia ai ma e sili atu le tau nai lo le resini Suspension.O le resini vasega pa'u o lo'o fa'auluina vaila'au emulsifying ma catalysts fa'atasi ai.O le mea lea e itiiti ifo le mama nai lo Suspension Polymerized poʻo le Bulk Polymerized PVC.Ole mea tau Eletise ole fa'apipi'i grade resin plastisols e sili atu le mativa nai lo Suspension Resin Compounds.O le manino e sili atu le leaga nai lo Suspension poʻo Bulk PVC.Fa'apipi'i grade resin e fa'atusatusa i le fausaga, ma e le fa'afefe tele le Plasticiser i le vevela o le potu.O le vevela e sili atu i le 160-180oC e manaʻomia e ave ai le palasitika i totonu o le Resin aʻo faʻamalolo.Fa'apipi'i vasega Resin e fa'aaogaina tele mo Fuga Vinyl Foliga lautele lautele.E fa'apipi'i 'ese'ese 'ese'ese o pa'u fa'apitoa e fa'apipi'iina i luga o se mea fa'atatau (Direct Coating) po'o luga ole Pepa Fa'asa'o (Transfer coating).E fa'apipi'i fa'apalapala i totonu o ogaumu uumi ma taai i luga pe a uma ona aveese le pepa.O le fogafale lelei ta'avale e mafai ona iai se fa'aofuofu semitransparent faigata i luga o laulau lolomi ma fa'afu'a o lo'o nofo i luga o peleue pito sili ona fa'atumu e fa'atupu ai le mafiafia.E tele a'afiaga sili ona manaia ma mauoa e mafai ma o nei mea e fai ma sui o le pito maualuga o Vinyl Flooring.
PVC Polymerised tele
Ole Bulk Polymerization e maua ai le sili ona mama ole PVC resin aua e leai ni mea e fa'amulumuluina po'o ni fa'amalo le fa'aogaina.E masani ona faʻaaogaina i talosaga manino.E masani lava ona maua i vaega pito i lalo K taua, e pei o Unplasticised PVC Foils mo Blister Packaging ma isi Calendered/Extruded Transparent ata tifaga e sili ona gaosia mai togi maualalo K Value.Fa'alelei ile Suspension resin technology ua fa'ate'a ese ai le Bulk PVC ile taimi ua tuana'i.
Copolymer PVC
Vinyl Chloride o loʻo faʻapipiʻiina faʻatasi ma comonomers pei o Vinyl acetate e tuʻuina atu ai le tele o resini ma mea faʻapitoa.PVAc poʻo Copolymer o Vinyl Chloride ma Vinyl acetate e sili ona taua.O le solubility lelei i solvents o le PVAc e avea ma filifiliga sili mo Vinyl Printing Inks ma solvent sima.O loʻo i ai se faʻaoga faʻapitoa o le PVAc i le Floor tiling ma o le resin o le filifiliga mo Vinyl Asbestos tiles.O le Resin e moni lava o se fusi nai lo le mea autu.Faʻatasi ai ma le Copolymer Resin e mafai ona gaosia ai le fola o le fale ma faʻatumu e pei o Asbestos ma Calcium Carbonate faʻamaumauga mo le 84% faʻatasi ai ma le Copolymer ma isi mea faʻapipiʻi faʻapipiʻi i lalo ifo o le 16%.O tulaga maualuga faapena e le mafai i le resin Suspension ona o lona liusuavai e sili atu ona maualuga ma e le mafai ona ofuina ma faʻapipiʻi ia maualuga maualuga o le faʻatumu.E manaʻomia ni nofoaafi faʻapitoa mo le Vinyl asbestos tiles.Ae peita'i ona o le pa'u'ese o le Asbestos, o ia oloa ua mou malie atu.
