Hydroxypropyl methyl cellulose ether (HPMC) nwere ọrụ nke njide mmiri na ịgbara mmiri simenti na ngwa ngwa gypsum dabeere na gypsum, ma nwee ike imeziwanye nrapado na nkwụsi ike nke ngwa ngwa.
Ihe ndị dị ka okpomọkụ gas, okpomọkụ na ikuku ikuku na-enwe mmetụta dị njọ na ọnụego nke evaporation nke mmiri si na ciment mortar na gypsum dabeere na ngwaahịa. Ya mere, na oge ọ bụla, e nwere ụfọdụ ọdịiche na-agbakwụnye otu ego nke hydroxypropyl methylcellulose ether (HPMC) ngwaahịa iji nọgide na-arụ ọrụ mmiri.
Na wụsa ihe, enwere ike imezi mmetụta mkpọchi mmiri site n'ịbawanye ma na-ebelata obere akụkụ. Ọnụego njide mmiri nke hydroxypropyl methyl cellulose ether na oke okpomọkụ bụ isi uru index iji mara mma nke hydroxypropyl methyl cellulose ether.
Ngwaahịa hydroxypropyl methylcellulose (HPMC) dị elu nwere ike dozie nsogbu nke njigide mmiri dị elu nke ọma. N'oge okpomọkụ dị elu, karịsịa n'ebe ndị na-ekpo ọkụ ma na-ekpo ọkụ na chromatography na-ewu ụlọ, a chọrọ hydroxypropyl methylcellulose ether (HPMC) dị elu dị mkpa iji meziwanye njide mmiri nke slurry.
Hydroxypropyl methylcellulose ether (HPMC) dị elu nke ọma, na-ekesa methoxyl na hydroxypropyl otu ya n'ụdị usoro molekụla nke methylcellulose, nke nwere ike ịkwalite ọgbọ nke ikuku oxygen na njikọ hydroxyl na ether. Ikike ịrụ ọrụ na covalent bonds.
Ọ nwere ike ịchịkwa evaporation nke mmiri nke ọma site na ihu igwe na-ekpo ọkụ ma nweta mmetụta dị elu na-ekpochi mmiri. Enwere ike iji hydroxypropyl methylcellulose (HPMC) dị elu mee ihe na ngwa ngwa agwakọta na plasta.
Debe ihe niile siri ike na-emepụta ihe nkiri na-ekpo ọkụ, na mmiri na-eme ihe na-eme ka a na-ahapụ nwayọọ nwayọọ ruo ogologo oge, ma meghachi omume na ihe ndị dị ndụ na collagen iji hụ na ike njikọ na ike ike.
Ya mere, iji chekwaa mmiri na ebe a na-ewu ihe n'oge okpomọkụ, anyị ga-agbakwunye ngwaahịa hydroxypropyl methylcellulose (HPMC) dị elu dị ka usoro nhazi, ma ọ bụghị ya, ọ ga-abụ n'ihi enweghị coagulation, ike na-ebelata, mgbawa, gas drum. yana nsogbu ịdị mma ngwaahịa ndị ọzọ kpatara ihicha ngwa ngwa.
Nke a na-emekwa ka ihe isi ike nke ndị ọrụ na-ewu ụlọ. Ka okpomọkụ na-ebelata, ọnụọgụ hydroxypropyl methylcellulose ether (HPMC) ji nwayọọ nwayọọ na-ebelata iji nweta otu ọdịnaya mmiri.
