Hydroxypropyl MethylCellulose(HPMC)
CAS:9004-65-3
Hydroxypropyl MethylCellulose (HPMC) po'ohypromelose vai soluble methyl cellulose ether, lea e masani ona faʻaaogaina i le fausiaina, vailaʻau, meaʻai, mea teuteu, faʻamalo, vali, pei o le mafiafia, emulsifier, ata tifaga, fusi, faʻasalalau faʻasalalau, colloids puipuia. E mafai ona matou tuʻuina atu le HPMC masani, e mafai foʻi ona matou tuʻuina atu HPMC faʻaleleia e tusa ai ma manaʻoga o tagata faʻatau.A maeʻa le faʻaleleia ma le togafitiga, e mafai ona tatou maua oloa o loʻo faʻasalalau i le vai vave, faʻaumi le taimi tatala, anti-sagging, ma isi.

Talosaga masani a HPMC:
Fa'apipi'i Tile
●Fa'atumauina vai lelei: fa'aumi le taimi e tatala ai o le a sili atu ona lelei le fa'apipi'iina.
● Faʻaleleia le faʻapipiʻiina ma le faʻafefe faʻafefe: aemaise lava mo taʻavale mamafa.
● Lelei sili atu galuega: lubricity ma palasitika o le sima ua faʻamautinoa, e mafai ona faʻaoga faigofie ma vave.
Sima sima / mago fefiloi omea
● Faigofie fa'afefiloi fa'agogo fua ona o le vai malulu solubility: fa'aputu fa'aputu e mafai ona faigofie ona 'alofia, lelei mo ta'a mamafa.
●Fa'atumauina lelei le vai: puipuia o le gau o le vai i substrates, o lo'o teuina le vai talafeagai i totonu o le fa'afefiloi lea e fa'amaonia ai le umi o le sima.
●Faʻateleina le manaʻomia o le vai: faʻateleina le taimi tatala, faʻalauteleina le eria spry ma sili atu le faʻatulagaina o le tamaoaiga.
● Fa'afaigofie ona fa'asalalauina ma fa'aleleia atili le fa'afefeteina ona o le fa'aleleia atili.
Puti puipui
●Fa'atumauina le vai: fa'ateleina le vai i totonu o le slurry.
● Anti-sagging: pe a faʻasalalauina se ofutino mafiafia corrugation e mafai ona aloese mai.
● Faʻateleina fua o le paluga: faʻalagolago i le mamafa o le paluga mago ma le faʻatulagaina talafeagai, HPMC e mafai ona faʻateleina le tele o le paluga.
Faiga Fa'agata ma Fa'auma ( EIFS )
● Faʻaleleia le pipii.
● Lelei susu gafatia mo laupapa EPS ma substrate.
● Faʻaitiitia le ulufale mai o le ea ma le faʻaogaina o le vai.
Fa'avasegaina e le tagata lava ia
● Puipuiga mai le faʻafefe o le vai ma le palapala o mea.
●Leai se aafiaga i le slurry fluidity ma viscosity maualalo
HPMC, a'o ona uiga fa'atumauina vai e fa'aleleia atili ai le fa'ai'uga i luga.
Faatumu Ta'e
● Lelei sili atu galuega: mafiafia talafeagai ma palasitika.
●O le taofiofia o le vai e mautinoa ai le umi o taimi faigaluega.
●Sag teteʻe: faʻaleleia le gafatia o le fusifusia.
