Emulsion Stabilizer uye Binder
PVA inogona kushandiswa zvakanyanya seyekudzivirira colloid kana thickener kune emulsion polymerization yevinyl acetate (VAc) kana VAc/acrylate.ine anotevera maitiro: yakanakisa 0adhesiveness; yakawedzera yekutanga tack uye chiyero chekuomesa ichishandiswa nekuzadza;kupikisa kwakanyanya kumafuta;firimu rakanaka.
Mukugadzira fiber
Zvishandiso zviviri zvakakosha zvePVA zvinofanirwa kushandiswa sevinylon feedstock uye sizing agent yetextile.Sezvakagadzirwa zvevinylon fiber, zvine zvakanakira kuve wakakwira musimba, kunyudza hunyoro, kuramba kweabrasion, kuramba kwechiedza chezuva, corrosion kuramba uye chena muruvara.Inogona zvakare kuruka nedonje, shinda uye viscose faibha kana kungorukwa pachayo.Seajenti yekugadzira machira, haizoparare kana kushatisa nekunamira kwakanaka kune donje, hemp, polyester uye viscose fiber.
Pulp & PaperPVA yakawana kushandiswa kwakakura mukurapa kwepepa pamusoro sezvo iine yakanakisa kunamatira uye dispersibility uye haizokanganisa chivakwa chemamwe mabhandi anoshandiswa musanganiswa.Zvakanakira zvePVA uchishandisa:Simba repamusoro (kudhinda);Simba pamwe neZ-axis(bepa remukati simba);kupeta kuramba;Abrasive resistance;Kunatsiridza kutsvedzerera;Kunatsiridza kupenya kwepamusoro;Kusimudza kuramba kumafuta uye kunyungudutsa (barriere property).
Film
PVA inogona kushandiswa kugadzira firimu rinonyungudika nemvura uye firimu rekudzivirira mvura.PVA inowanikwa muzvigadzirwa zvakaumbwa zvinoratidzira zvemukati zvePVA, zvinoti, kusimba kwesimba, kupikisa organic solvent uye kusimba kwemhepo. Iwo ese ari maviri anoshandiswa zvakanyanya mu Package indasitiri, kwete yemucheka chete, asiwo yemakemikari, chikafu, makemikari emazuva ese, makemikari ekurima, dhayi, nezvimwe.
Dispersion Stabilizer
PVA, iyo yakanaka kwazvo mukudzivirira kwecolloid uye ine basa repamusoro pepamusoro, inowanzoshandiswa se dispersion stabilizer yekumisa polymerization yevinyl chloride monomer (VCM).Kuita kwePVC resin kunogona kuvandudzwa zvakanyanya nekusarudza yakakodzera PVA giredhi ine dhigirii rakakodzera repolymerization uye hydrolysis.
Isu tine anopfuura 1000m2 imba yekuchengetera yePVA kuve nechokwadi chekugadzika kwekupa uye mutengo unokwikwidza nguva dzose.
