Ole matafaioi ole hydroxypropyl methylcellulose

I le faʻaaogaina o mea faufale, o le hydroxypropyl methyl cellulose HPMC o se mea faʻapipiʻi faʻaoga masani,hydroxypropyl methyl celluloseo loʻo faʻaaogaina lautele i alamanuia, ma e iai ituaiga eseese, hydroxypropyl methyl cellulose e mafai ona vaevaeina i Mo le vai malulu vave ituaiga ma le vevela vevela.

Ole vai malulu ole HPMC e mafai ona fa'aogaina ile pa'u pa'u, sima, kelu vai, vali vai ma mea fa'a-kemikolo i aso uma. E masani ona faʻaogaina le HPMC vevela vevela i oloa paʻu matutu ma faʻafefiloi saʻo ma le paʻu mago mo le faʻaogaina o le toniga, e pei o le putty paʻu ma le sima, hydroxypropyl methylcellulose e mafai ona faʻaaogaina lautele e faʻaleleia ai le faʻatinoga o le sima, gypsum ma isi mea fau fale. I sima faʻavae sima, e faʻaleleia ai le taofiofia o le vai, faʻalauteleina le taimi faʻatulagaina ma le taimi tatala, ma faʻaitiitia ai le faʻafefe o le tafe.

Hydroxypropyl methylcellulose e mafai ona faʻaaogaina i le faʻafefiloi o mea faufale ma le fausiaina, ma faʻafefiloi faʻamago faʻafefiloi e mafai ona vave faʻafefiloi ma le vai e vave maua ai le faʻamalieina manaʻomia. O le cellulose eter e sili atu ona solo e aunoa ma le pipii. O le propyl methyl cellulose e mafai ona faʻafefiloi ma le paʻu mago i mea fau fale, o loʻo i ai uiga o le faʻasalalauina o le vai malulu, e mafai ona faʻapipiʻi lelei vaega maʻaʻa ma faʻafefiloi atili lelei ma tutusa. E le gata i lea, e faʻaleleia ai le lubricity ma le palasitika, faʻateleina masini, ma faʻafaigofie le fausiaina o oloa. Faʻaleleia le faʻatumauina o le vai, umi le taimi faigaluega, fesoasoani e puipuia le tafe i luga o le sima ma taʻavale, faʻaumiumi taimi malulu ma faʻaleleia le lelei o galuega.

O le Hydroxypropyl methylcellulose e faʻaleleia ai le malosi o le faʻapipiʻiina o tile, faʻaleleia le faʻafefeteina o le sima ma soʻoga laupapa, e le gata ina faʻateleina ai le ea i totonu o le sima, ae faʻaitiitia ai foi le avanoa e taʻe ai, e mafai foi ona faʻaleleia foliga o le oloa ma mafai. faʻaleleia le faʻatinoina o le anti-sag o le faʻapipiʻi tile.
