O le vave hydroxypropyl methylcellulose ether ua mamanuina mo oloa faʻavae vai. O le pito i luga ole hydroxypropyl methylcellulose ether e togafitia ile glyoxal i lalo ole vevela ma le pH tau. O le hydroxypropyl methyl cellulose ether o loʻo togafitia i lenei auala e naʻo le faʻasalalauina i totonu o le vai malulu e aunoa ma le fula ma le viscosity, lea e faia se sao i le tolopoina o le fula. I le taimi lea, o le vaifofo vai o loʻo faʻaosoina mo le 5-10 minute poʻo le A faʻapipiʻi le siosiomaga fofo (tau o le PH) e avea ma alkaline, o le hydroxypropyl methylcellulose ether e amata ona fulafula ma faʻatupu le viscosity. O lenei ituaiga e togafitia i luga e masani ona taʻua o se ituaiga vave.
O le uiga o le hydroxypropyl methylcellulose vave o le taimi e fetaui ma vai malulu, e vave ona sosolo i le vai malulu, ae e umi se taimi e alu aʻe ai lona viscosity, aua e naʻo le faʻafefe i le vai i le taimi muamua, ma e le solo i totonu o se lagona taua. O lona viscosity e oʻo i le maualuga maualuga mo le tusa ma le 20 minute pe sili atu. O le lelei o lenei mea o loʻo faʻaaogaina i totonu o se pisinisi faʻapitoa e aunoa ma le faʻafefiloi o le paʻu mamago, pe a manaʻomia ona faʻamavae ma e le mafai ona faʻaogaina le vai vevela ona o tulaga o meafaigaluega ma isi mafuaaga. Ole hydroxypropyl methylcellulose vave e foia ai sea faafitauli.
O le hydroxypropyl methylcellulose vave faʻasalalau vave i totonu o le vai (tulaga faʻasalalau e 100%), faʻamavae vave, e le faʻapipiʻi, aemaise lava i le taimi mulimuli ane, o le colloidal solution e maualuga le manino (e oʻo atu i le 95%) ma le tele o le tumau, lea e foia ai faafitauli. i fa'atinoga fa'atino. Faʻatapulaʻaina, faʻalauteleina le faʻaogaina o le faʻaogaina, e pei o le faʻaogaina i le kelu faufale, le faʻaogaina i mea faʻafefiloi vai faʻafefiloi, ma fanua faʻapitoa e pei o le fufuluina o vailaʻau i aso uma.
Ua matou faʻalauiloaina le gaosiga o masini ma tekonolosi faʻaonaponei, maua se laina faʻaonaponei o le cellulose ether ma redispersible latex paʻu, ma faʻamautinoa e tuʻuina atu i tagata faʻaoga oloa faʻamalieina ma lona faiga faʻatonutonu lelei, faiga suʻesuʻe ma le auaunaga atoatoa i luga ole laiga. O le taimi nei o oloa taʻutaʻua o le hydroxypropyl methylcellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch eter HPS, redispersible latex pauta faasologa. O oloa o loʻo faʻaaogaina lautele i le fausiaina, vailaʻau vailaʻau, vali, vailaʻau vailaʻau i aso taʻitasi, alamanuia militeri ma isi faʻalapotopotoga, ma ua faʻasolosolo ona faia i ni mea e fai ata tifaga, faʻapipiʻi, dispersants, stabilizers, thickeners, etc.
Faʻalagolago i lona lava oloa lelei ma lona tulaga ma le aafiaga i le paʻu mamago fale meafaitino faʻaopoopo alamanuia, ma i lalo o le nofoaga o le tausia pea o le misiona faʻapitoa o le lelei muamua, o loʻo galulue faʻatasi nei ma le atunuʻu ma le atunuʻu taʻutaʻua gaosi oloa mo oloa faʻaopoopo. Lagolago galuega: polypropylene fiber, Wood fiber, fetuutuunai starch ether, polyvinyl alcohol powder, powder defoamer, vai faʻaitiitia, vai faʻafefe, calcium formate ma isi mea faʻapipiʻi paʻu mamago.
