I-Emulsion Stabilizer & Binder
I-PVA ingasetyenziswa ngokubanzi njenge-colloid yokukhusela okanye i-thickener ye-emulsion polymerization ye-vinyl acetate (VAc) okanye i-VAc / acrylate.inezi mpawu zilandelayo: okugqwesileyo okuncamathelayo;ukwenyuka kokuthotywa kokuqala kunye nesantya sokumisa ngelixa isetyenziswa nesigcwalisi;ukumelana okugqwesileyo kwioli;ifilimu ebalaseleyo.
Kwimveliso yefiber
Izicelo ezimbini ezibalulekileyo zePVA kufuneka zisetyenziswe njenge-vinylon feedstock kunye ne-agent ye-agent ye-textile.As imathiriyeli ekrwada ye-vinylon fiber, ineenzuzo zokuba namandla aphezulu, ukufunxa ukufuma, ukuxhathisa kwe-abrasion, ukumelana nokukhanya kwelanga, ukuxhathisa ukubola kunye nombala omhlophe.Isenokuphothwa ngomqhaphu, uboya kunye nefayibha ye-viscose okanye isongwe ngokwayo ngokwayo. Njengesixhobo sokulinganisa impahla, ayizukonakala okanye yonakalise ngokuncamathela kakuhle kumqhaphu, i-hemp, i-polyester kunye ne-viscose fiber.
I-Pulp & PaperPVA ifumene ukusetyenziswa okubanzi kunyango lomphezulu wephepha njengoko inokunamathela okugqwesileyo kunye nokusasazeka kwaye ayiyi kuchaphazela ipropati yezinye izibophelelo ezisetyenziswe ngokudibeneyo.Izinto eziluncedo zePVA usebenzisa: Amandla omphezulu (ukushicileka); Amandla ecaleni kwe-axis ye-Z (amandla angaphakathi ephepha); Ukumelana nokugoba; Ukumelana ne-Abrasive; Ukuguda okuphuculweyo; Ukuphuculwa kokukhazimla komphezulu; Ukunyusa ukuchasana ne-oyile kunye ne-solvent (ipropathi yomqobo).
Ifilimu
I-PVA ingasetyenziselwa ukuvelisa ifilimu enyibilikayo yamanzi kunye nefilimu enganyangekiyo yamanzi. I-PVA ifumaneka kwiimveliso ezenziweyo ezibonisa iimpawu ze-PVA, ezizezi, amandla aphezulu, ukuchasana ne-solvent ephilayo kunye nokuqina komoya. Zombini zisetyenziswa ngokubanzi kwi Umzi-mveliso wepakethe, kungekuphela nje welaphu, kodwa nakwimichiza, ukutya, iikhemikhali zemihla ngemihla, iikhemikhali zezolimo, idayi, njalo njalo.
I-Dispersion Stabilizer
I-PVA, egqwesileyo kukhuseleko lwe-colloid kwaye inomsebenzi ongaphezulu komphezulu, ihlala isetyenziswa njenge-dispersion stabilizer ye-polymerization yokumiswa kwe-vinyl chloride monomer (VCM).Ukusebenza kwePVC resin kunokuphuculwa kakhulu ngokukhetha ibakala elifanelekileyo lePVA kunye neqondo elifanelekileyo lepolymerization kunye nehydrolysis.
Sinendawo yokugcina impahla engaphezulu kwe-1000m2 yePVA ukuze siqiniseke ukuba kukho unikezelo oluzinzileyo kunye nexabiso elikhuphisanayo ngalo lonke ixesha.
