Cellulose ether hpmc nwere ọrụ nke njigide mmiri na ịgbanye na ngwa ngwa ciment na ngwa agha gypsum, nke nwere ike imeziwanye nkwụsi ike 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, e nwere ụfọdụ dị iche iche na-agbakwụnye otu ego nke HPMC ngwaahịa na-ejigide mmiri na-arụ ọrụ na oge ọ bụla.
Na wụsa ihe, enwere ike imezi mmetụta mkpọchi mmiri site n'ịbawanye ma na-ebelata obere akụkụ. Ọnụego njide mmiri nke methyl cellulose ether na oke okpomọkụ bụ isi uru index iji mara mma nke methyl cellulose ether.
Ngwaahịa HPMC dị elu nwere ike dozie nsogbu nke ikpochi mmiri dị elu nke ọma. N'oge okpomọkụ dị elu, karịsịa n'ebe ndị na-ekpo ọkụ ma na-ekpo ọkụ na-arụ ọrụ chromatography, HPMC dị elu dị mkpa iji meziwanye njide mmiri nke slurry.
HPMC dị elu nwere oke nha nke ọma, a na-ekesakwa otu methoxyl na hydroxypropyl n'ụdị cellulose molekụla, nke nwere ike ịkwalite ikike nke mkpụrụ ndụ oxygen na-etolite njikọ dị n'otu na njikọ hydroxyl na ether.
Ọ nwere ike ịchịkwa evaporation nke mmiri nke ọma site na ihu igwe na-ekpo ọkụ ma nweta mmetụta mkpuchi mmiri dị elu. Enwere ike iji methylcellulose methylcellulose dị elu mee ihe na ngwa ngwa agwakọta na plasta nke ọrụ paris.
Debe ihe niile siri ike iji mepụta 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 inorganic na ihe collagen iji hụ na ike njikọ na ike ike.
Ya mere, n'ebe okpomọkụ na-ekpo ọkụ na-ewu ụlọ, iji nweta mmetụta nke ịzọpụta mmiri, anyị ga-agbakwunye ngwaahịa HPMC dị elu dị ka uzommeputa si dị, ma ọ bụghị ya, a ga-eme ya site na enweghi ike siri ike, belata ike, mgbawa, gas drum. na nsogbu àgwà ngwaahịa ndị ọzọ. Na-ebute nkụ ngwa ngwa.
Nke a na-emekwa ka ihe isi ike nke ndị ọrụ na-ewu ụlọ. Ka okpomọkụ na-ebelata, ọnụọgụ HPMC agbakwunyere ji nwayọọ nwayọọ na-ebelata iji nweta otu ọdịnaya mmiri.
