I-Emulsion Stabilizer & Binder
I-PVA ingasetshenziswa kabanzi njenge-colloid evikelayo noma i-thickener ye-emulsion polymerization ye-vinyl acetate (VAc) noma i-VAc/acrylate.inezici ezilandelayo: ukunamathela okuhle kakhulu kwe-0;ukwenyuka kwe-tack yokuqala kanye nezinga lokomisa ngenkathi isetshenziswa nesigcwalisi;ukumelana okuhle kakhulu kwamafutha;ifilimu evelele.
Ekwenziweni kwe-fiber
Izicelo ezimbili ezibalulekile ze-PVA kufanele zisetshenziswe njenge-vinylon feedstock kanye ne-sizing agent ye-textile.Njengoba impahla eluhlaza ye-vinylon fiber, inezinzuzo zokuba namandla aphezulu, ukumuncwa komswakama, ukumelana nemihuzuko, ukumelana nokukhanya kwelanga, ukumelana nokugqwala kanye nombala omhlophe.Ingakwazi futhi ukuphothwa ngokotini, uvolo kanye ne-viscose fiber noma iphothwe ngokwayo. Njenge-ejenti yokulinganisa yendwangu, Ngeke igle noma yonakale uma inamathela kahle ukotini, i-hemp, i-polyester ne-viscose fiber.
I-Pulp & PaperPVA ithole ukusetshenziswa okubanzi ekwelapheni indawo yephepha njengoba inokunamathela okuhle kakhulu nokuhlakazeka futhi ngeke kuthinte impahla yezinye izibophezelo ezisetshenziswa ngokuhlangana.Izinzuzo zokusebenzisa i-PVA: Amandla obuso (ukuphrinta); Amandla ahambisana ne-axis engu-Z (amandla angaphakathi ephepha); Ukumelana nokugoqa; Ukumelana ne-Abrasive; Ubushelelezi obuthuthukisiwe; Ukucwebezela okuthuthukisiwe kwendawo; Ukuphakama okumelana nowoyela ne-solvent (impahla yokuvimbela).
Ifilimu
I-PVA ingasetshenziselwa ukukhiqiza ifilimu encibilikayo emanzini kanye nefilimu engamelana namanzi. I-PVA itholakala emikhiqizweni eyakhiwe egqamisa izici zemvelo ze-PVA, okungukuthi, amandla aqine kakhulu, ukumelana ne-organic solvent kanye nokuqina komoya. Zombili zisetshenziswa kabanzi eku imboni yephakheji, hhayi eyendwangu kuphela, kodwa futhi namakhemikhali, ukudla, amakhemikhali ansuku zonke, amakhemikhali ezolimo, udayi, njll.
I-Dispersion Stabilizer
I-PVA, esebenza kahle kakhulu ekuvikelweni kwe-colloid futhi inomsebenzi osezingeni eliphezulu, ivamise ukusetshenziswa njengesiqinisi sokuhlakazeka sokumiswa kwe-polymerization ye-vinyl chloride monomer (VCM).Ukusebenza kwe-PVC resin kungenziwa kahle kakhulu ngokukhetha i-PVA grade efanelekile enezinga elifanele le-polymerization kanye ne-hydrolysis.
Sinendlu yokugcina impahla engaphezu kuka-1000m2 ye-PVA ukuze siqinisekise ukunikezwa okuzinzile kanye nentengo encintisanayo njalo.
