Ebe ọ bụ na ihe ndị dị na hydroxypropyl methylcellulose yiri ether ndị ọzọ na-agbaze na mmiri, enwere ike iji ya na mkpuchi emulsion na ihe mkpuchi resin mmiri na-agbaze dị ka ihe na-emepụta ihe nkiri, ihe na-eme ka ihe dị arọ, ihe na-eme ka ihe dị nro na ihe na-eme ka ihe dị jụụ, wdg, nke na-enye ihe mkpuchi ahụ ezigbo ike iguzogide abrasion. Mkpuchi na njikọta dị iche iche, yana nrụgide elu ka mma, nkwụsi ike na asịd na ntọala, yana ndakọrịta na agba ígwè.
Ebe ọ bụ na HPMC nwere ebe gel dị elu karịa MC, ọ na-eguzogidekwa mwakpo nje bacteria karịa cellulose ethers ndị ọzọ, ya mere enwere ike iji ya dị ka ihe na-eme ka ihe dị arọ maka mkpuchi emulsion mmiri.

Ojiji nke hydroxypropyl methyl cellulose n'ime ụlọ ọrụ mkpuchi bụ otu a.
1.

2. hydroxypropyl methyl cellulose nke a na-eji dochie anya ya nke ukwuu nwere ike iguzogide mwakpo nje karịa obere mgbanwe, ọ na-enwekwa ike iguzogide viscosity ka mma na ihe ndị na-eme ka polyvinyl acetate sie ike. Ether cellulose ndị ọzọ dị n'ebe a na-echekwa ha n'ihi mmebi nke cellulose ether ma na-eme ka viscosity mkpuchi ahụ belata.
3. Ihe na-agba agba agba nwere ike ịbụ HPMC nke mmiri na-agbaze (ebe methoxy dị 28% ruo 32%, hydroxypropoxy bụ 7% ruo 12%), dioxymethane, toluene, paraffin, ethanol, nhazi methanol, a ga-etinye ya n'elu kwụ ọtọ, yana viscosity achọrọ na mgbanwe. Ihe na-agba agba agba a na-ewepụ ọtụtụ agba agba nkịtị, varnishes, enamel, na ụfọdụ epoxy esters, epoxy amides, catalyzed epoxy amides, acrylates, wdg. Enwere ike iwepụ ọtụtụ agba n'ime sekọnd ole na ole, ụfọdụ agba chọrọ nkeji 10 ~ 15 ma ọ bụ karịa, ihe na-agba agba agba a dabara adaba karịsịa maka elu osisi.
4. Agba emulsion mmiri nwere ike ịbụ akụkụ 100 nke agba inorganic ma ọ bụ organic, akụkụ 0.5 ~ 20 nke alkyl cellulose ma ọ bụ hydroxyalkyl cellulose nke mmiri na-agbaze na akụkụ 0.01 ~ 5 nke polyoxyethylene ether ma ọ bụ ether ester. Dịka ọmụmaatụ, a na-enweta agba ahụ site na ịgwakọta akụkụ 1.5 nke HPMC, akụkụ 0.05 nke polyethylene glycol alkyl phenyl ether, akụkụ 99.7 nke titanium dioxide na akụkụ 0.3 nke carbon black.
