Talu ai o meatotino o le hydroxypropyl methylcellulose e tutusa ma isi ethers e mafai ona faʻafefeteina vai, e mafai ona faʻaaogaina i le emulsion coatings ma vai-soluble resin coating vaega e avea o se sui fai ata tifaga, mafiafia, emulsifier ma stabilizer, ma isi, lea e maua ai le ata faʻapipiʻi. lelei abrasion tetee. Faʻapipiʻi tutusa ma faʻapipiʻi, ma faʻaleleia atili le vevesi o luga, mautu i meaʻai ma faʻavae, ma fetaui ma lanu uʻamea.
Talu ai ona o le HPMC o loʻo i ai se maualuga maualuga o le gel nai lo le MC, e sili atu foi ona tetee atu i siama siama nai lo isi ethers cellulose, ma o lea e mafai ona faʻaaogaina e avea o se sui mafiafia mo paʻu emulsion aqueous. HPMC o loʻo i ai le mautu lelei o le teuina o le viscosity ma lona dispersibility sili ona lelei, o lea e fetaui lelei le HPMC e avea o se faʻasalalau i coatings emulsion.
O le faʻaogaina o le hydroxypropyl methyl cellulose i totonu o le fale faʻapipiʻi e faʻapea.
1.various viscosity HPMC faatulagaga vali ofu tetee, maualuga vevela tetee, faamatalaga aneti-bacterial, fufulu tetee ma mautu i acids ma faavae e sili atu; e mafai fo'i ona fa'aaogaina e fai ma vali vali e iai le methanol, ethanol, propanol, isopropyl alcohol, ethylene glycol, acetone, methyl ethyl ketone po'o le diketone alcohol thickener; HPMC formulated emulsified coatings maua lelei abrasion susu; HPMC nai lo le HEC ma le EHEC ma le CMC aua e sili atu le aafiaga o le HPMC nai lo le HEC ma le EHEC ma le CMC e fai ma vali vali.
2. Highly suitulaga hydroxypropyl methyl cellulose e sili atu ona tetee atu i siama siama nai lo le maualalo o le suitulaga, ma e sili atu le mautu viscosity i polyvinyl acetate mafiafia. O isi cellulose ethers o loʻo teuina ona o le faʻaleagaina o filifili o le cellulose ether ma faʻaitiitia ai le viscosity coating.
3. paint stripper e mafai ona vai-soluble HPMC (lea o le methoxy e 28% i le 32%, hydroxypropoxy o le 7% i le 12%), dioxymethane, toluene, paraffin, ethanol, methanol configuration, o le a faʻaaogaina i luga o le saʻo, ma le viscosity manaʻomia ma volatility. O lenei vali e aveese ai le tele o vali faʻafefe masani, varnishes, enamels, ma nisi epoxy esters, epoxy amides, catalyzed epoxy amides, acrylates, ma isi. E tele vali e mafai ona paʻu ese i ni nai sekone, o nisi vali e manaʻomia 10 ~ 15min pe sili atu, lenei. e sili ona talafeagai le vali vali mo luga o laupapa.
4.Water emulsion vali e mafai ona aofia ai le 100 vaega o inorganic po o organic pigmenti, 0.5 ~ 20 vaega o vai-soluble alkyl cellulose po hydroxyalkyl cellulose ma 0.01 ~ 5 vaega o le polyoxyethylene eter po o le ester ester. Mo se faʻataʻitaʻiga, e maua le lanu e ala i le faʻafefiloi o le 1.5 vaega o le HPMC, 0.05 vaega o le polyethylene glycol alkyl phenyl ether, 99.7 vaega o le titanium dioxide ma le 0.3 vaega o le carbon black. Ona faʻafefiloi lea o le paluga i le 100 vaega o le 50% solid polyvinyl acetate e maua ai le faʻapipiʻiina, ma e leai se eseesega i le va o le faʻamago faʻapipiʻi ata na faia e ala i le faʻaogaina i luga o le pepa mafiafia ma solo mama i se pulumu.
