I te mea he rite ngā āhuatanga o te hydroxypropyl methylcellulose ki ētahi atu etera wairewa-wai, ka taea te whakamahi i roto i ngā paninga emulsion me ngā wāhanga paninga kapia wairewa-wai hei kaihanga kiriata, hei whakamātotoru, hei emulsifier me hei whakaū, hei whakarato i te ātete pai ki te kiriata paninga. He paninga ōrite me te piri, ā, he pai ake te kukū o te mata, te pumau ki ngā waikawa me ngā turanga, me te hototahi ki ngā tae whakarewa.
Nā te mea he teitei ake te ira tio o te HPMC i te MC, he ātete ake hoki ki te whakaekenga huakita i ētahi atu etera cellulose, nō reira ka taea te whakamahi hei whakamātotoru mō ngā paninga emulsion wai. He pai te pumau o te rokiroki matotoru o te HPMC, ā, he tino pai te horapa, nō reira he tino pai te HPMC hei kaiwhakamarara i roto i ngā paninga emulsion.
Ko te whakamahinga o te hydroxypropyl methyl cellulose i roto i te umanga paninga ko te penei.
1. He pai ake te ātete ki te kakahu peita i roto i te whirihoranga HPMC matotoru, te ātete pāmahana teitei, te whakamārama anti-huakita, te ātete horoi me te pumau ki ngā waikawa me ngā turanga; ka taea hoki te whakamahi hei tango peita kei roto ko te methanol, te etanoru, te propanol, te waipiro isopropyl, te ethylene glycol, te acetone, te methyl ethyl ketone, te waipiro diketone rānei; he pai te ātete mākū o ngā paninga emulsified HPMC; he pai ake te pānga o te HPMC i te HEC me te EHEC me te CMC hei whakamaroke peita i te HEC me te EHEC me te CMC.
2. He pai ake te ātete o te hydroxypropyl methyl cellulose kua tino whakakapia ki te whakaekenga huakita i te iti o te whakakapinga, ā, he pai ake te pumau o te matotoru i roto i ngā whakamātotoru polyvinyl acetate. Kei te rongoahia ētahi atu cellulose ethers nā te mea kua pakaru te mekameka o te cellulose ether, ā, ka whakaitihia te matotoru o te paninga.
3. Ka taea te whakamahi i te HPMC wairewa-wai mō te tango peita (ko te methoxy he 28% ki te 32%, ko te hydroxypropoxy he 7% ki te 12%), te dioxymethane, te toluene, te paraffin, te ethanol, te methanol, ka pania ki te mata poutū, me te matotoru me te āhua hurihuri e hiahiatia ana. Ka tangohia e tēnei tango peita te nuinga o ngā peita rehu tuku iho, ngā wanihi, ngā enamel, me ētahi epoxy esters, epoxy amides, epoxy amides catalyzed, acrylates, me ētahi atu. He maha ngā peita ka taea te tihore i roto i ētahi hēkona, ko ētahi peita e hiahia ana kia 10~15 meneti neke atu rānei, he tino pai tēnei tango peita mō ngā mata rakau.
4. Ka taea te hanga i te peita wai whakapūkara mai i te 100 wāhanga o te tae kore-waro, te tae waro rānei, 0.5~20 wāhanga o te alkyl cellulose wairewa-wai, te hydroxyalkyl cellulose rānei, me te 0.01~5 wāhanga o te polyoxyethylene ether, te ether ester rānei. Hei tauira, ka whiwhihia te tae mā te whakaranu i te 1.5 wāhanga o te HPMC, 0.05 wāhanga o te polyethylene glycol alkyl phenyl ether, 99.7 wāhanga o te titanium dioxide me te 0.3 wāhanga o te waro pango. Kātahi ka whakaohokia te ranunga ki te 100 wāhanga o te 50% polyvinyl acetate totoka hei whiwhi i te paninga, ā, kāore he rerekētanga i waenga i te kiriata paninga maroke i hangaia mā te paninga ki runga i te pepa matotoru me te mirimiri mārire ki te paraihe.
