Emulsion Stabilizer & Fa'amau
E mafai ona fa'aaogaina lautele le PVA e avea ma colloid puipuia po'o le mafiafia mo le polymerization emulsion o le vinyl acetate (VAc) po'o le VAc / acrylate.o lo'o i ai uiga nei: sili ona pipi'i; fa'atupuina le tack muamua ma le fua fa'agogo a'o fa'aoga ma fa'atumu;sili ona tetee i le suauu;ata mata'ina.
I le gaosiga o fiber
E lua talosaga taua o le PVA e tatau ona faʻaaogaina e pei o le vinylon feedstock ma le sizing agent mo textile.As raw material of vinylon fiber, ei ai le lelei o le maualuga i le malosi, susu faʻafefe, abrasion teteʻe, susulu o le la, corrosion teteʻe ma paʻepaʻe i le lanu.E mafai foi ona milo i le ie, fulufulu mamoe ma alava viscose pe milo mama ia lava.As sui sizing mo ie, O le a le corrode pe deteriorate ma se pipii lelei i cotton, hemp, polyester ma viscose fiber.
O le Pulp & PaperPVA ua maua le tele o le fa'aoga i le togafitia o luga o le pepa ona e sili ona lelei le pipii ma le fa'asalalauina ma e le afaina ai meatotino a isi fusi fa'aoga fa'atasi.O le lelei o le PVA faʻaaogaina: Malosi i luga (lolomi) ; Malosi i luga o le Z-axis (pepa malosi i totonu); gaugau teteʻe; abrasive teteʻe; faʻaleleia le lamolemole; faʻaleleia le susulu o luga; faʻatupuina le teteʻe i le suauʻu ma solvent (mea pa puipui).
Ata tifaga
E mafai ona faʻaaogaina le PVA e gaosia ai le vai soluble film ma le vai-resistance film.PVA o loʻo maua i mea faʻapipiʻi e faʻamaonia ai uiga faʻapitoa o le PVA, o lona uiga, maualuga le malosi, tetee atu i le solvent organic ma le ea. afifiina alamanuia, e le gata mo ie, ae faapea foi mo vailaau, meaai, vailaau i aso taitasi, faatoaga vailaau, dyestuff, ma isi.
Fa'amautu Ta'ape
PVA, lea e sili ona lelei i le puipuiga o le colloid ma e sili atu le gaioiga o luga, e masani ona faʻaaogaina e avea ma faʻamautu faʻasalalau mo le faʻamavaeina o le polymerization o le vinyl chloride monomer (VCM).O le faʻatinoga o le PVC resin e mafai ona faʻamalieina tele e ala i le filifilia o se vasega PVA talafeagai ma le tikeri talafeagai o le polymerization ma le hydrolysis.
E sili atu nai lo le 1000m2 fale teu oloa mo le PVA e faʻamautinoa ai le tuʻuina atu ma le tau faʻatauva i taimi uma.
