Mai i te mea he rite nga ahuatanga o te hydroxypropyl methylcellulose ki etahi atu ethers wairewa-wai, ka taea te whakamahi i roto i nga paninga whakaehunga me nga waahanga whakakikorua o te wai-wairewa-wai-wai-wai-wairewa hei kaihoko hanga kiriata, te whakamaarama, te emulsifier me te stabilizer, me etahi atu, e homai ana i te kiriata paninga. ātete abrasion pai. Ko te paninga homogene me te piri, me te pai ake o te maataki o te mata, te pumau ki nga waikawa me nga turanga, me te hototahi ki nga poaka whakarewa.
I te mea he teitei ake te ira kiri o te HPMC i te MC, he kaha ake te atete ki te whakaeke huakita i era atu etera cellulose, na reira ka taea te whakamahi hei maatete whakamaarama mo nga paninga whakaehunga wai. He pai te pumau o te rokiroki pokey a HPMC me tona mararatanga pai, na reira he pai te HPMC hei whakamarara i roto i nga paninga whakaehunga.
Ko te whakamahinga o te hydroxypropyl methyl cellulose i roto i te ahumahi whakakikorua e whai ake nei.
1.various pokey whirihoranga HPMC peita kakahu ātete, teitei ātete pāmahana, whakamārama anti-huakita, horoi ātete me te pūmautanga ki te waikawa me te turanga he pai ake; ka taea hoki te whakamahi hei peera peita kei roto te methanol, te waihano, te propanol, te waipiro isopropyl, te ethylene glycol, te acetone, te methyl ethyl ketone, te waipiro diketone waipiro ranei; Ko nga whakakikorua kua hangaia e te HPMC he pai rawa te abrasion maku; Ko te HPMC i te HEC me te EHEC me te CMC i te mea he pai ake te painga o te HPMC i te HEC me te EHEC me te CMC hei peita peita.
2.Highly substituted hydroxypropyl methyl cellulose he pai ake te aukati ki te whakaeke huakita i te iti o te whakakapinga, me te pai ake o te whakapumautanga i roto i te polyvinyl acetate thickeners. Ko etahi atu etera cellulose kei roto i te rokiroki na te kino o te mekameka o te cellulose ether me te whakaheke i te pokey paninga.
3.Ka taea e te kaihoroi peita te wai-wairewa HPMC (kei te 28% ki te 32% te methoxy, ko te hydroxypropoxy te 7% ki te 12%), te dioxymethane, te toluene, te paraffin, te ethanol, te whirihoranga methanol, ka whakamahia ki te mata tika, me te pokey e hiahiatia ana me te pähekeheke. Ka whakakorehia e tenei kaitapa peita te nuinga o nga peita rehu tikanga, nga kaera, nga tohu, me etahi epoxy esters, epoxy amides, catalyzed epoxy amida, acrylates, me etahi atu. he pai rawa te kaihoroi peita mo nga papa rakau.
4.Water whakaehunga peita e taea te tito o 100 wahi o pararopi, pararopi pigment ranei, 0.5~20 wahi o te wai-wairewa alkyl cellulose ranei hydroxyalkyl cellulose me te 0.01~5 wahi o te polyoxyethylene etera hākawa eter ranei. Hei tauira, ka whiwhi te tae ma te whakaranu i nga wahanga 1.5 o te HPMC, 0.05 nga wahanga o te polyethylene glycol alkyl phenyl ether, 99.7 nga wahanga o te titanium dioxide me te 0.3 nga wahanga o te waro pango. Ka whakaohohia te ranunga ki te 100 nga waahanga o te 50% polyvinyl acetate totoka kia whiwhi ai i te paninga, kaore he rereketanga i waenga i te kiriata paninga maroke i hangaia ma te tono ki runga pepa matotoru me te mirimiri ngawari ki te paraihe.
