Hydroxypropyl methylcellulose bụ otu n'ime ihe mgbakwunye ether cellulose dị mkpa na ngwa ngwa akọrọ ma nwee ọtụtụ ọrụ na ngwa agha.Ọrụ bụ isi nke hydroxypropyl methylcellulose na ngwa ngwa ciment bụ njide mmiri na ịgbatị.Tụkwasị na nke ahụ, n'ihi mmekọrịta ya na usoro ciment, ọ nwekwara ike ịrụ ọrụ na-eme ka ikuku dịkwuo elu, nkwụsịtụ nkwụsị, na imeziwanye ike nke njikọ nkwụsị.Mmetụta.
Ọrụ kachasị mkpa nke hydroxypropyl methylcellulose na ngwa agha bụ njigide mmiri.Dị ka a cellulose ether admixture na ngwa agha, hydroxypropyl methylcellulose nwere ike iji na ihe fọrọ nke nta niile ngwa ngwa ngwaahịa, tumadi n'ihi na ya mmiri njide Njirimara.N'ikwu okwu n'ozuzu, njide mmiri nke hydroxypropyl methylcellulose metụtara viscosity ya, ogo nke nnọchi na nha nha.
Hydroxypropyl methylcellulose na-eji dị ka a thickener, na ndim mmetụta na-metụtara ogo nke nnọchi, urughuru size, viscosity na ogo mgbanwe nke hydroxypropyl methylcellulose.N'ikwu okwu n'ozuzu, ọkwa dị elu nke nnọchi na viscosity nke cellulose ether, nke nta nke nta ahụ na-apụta ìhè na mmetụta na-egbuke egbuke.
Na hydroxypropyl methylcellulose, iwebata otu methoxy na-ebelata ike elu nke ngwọta mmiri nwere hydroxypropyl methylcellulose, nke mere na hydroxypropyl methylcellulose nwere mmetụta na-akpali ikuku na ngwa ngwa ciment.Webata ọnụ ọgụgụ kwesịrị ekwesị nke afụ n'ime ngwa agha ahụ.N'ihi "mmetụta bọọlụ" nke afụ,
A na-eme ka arụ ọrụ nke ngwa agha dịkwuo mma, ebe ntinye nke ikuku ikuku na-abawanye mkpụrụ nke ngwa agha.N'ezie, ọ dị mkpa ka a chịkwaa ọnụ ọgụgụ ikuku etinyere.Mgbe nnukwu ikuku na-abanye, ọ nwere ike imetụta ike nke ngwa agha na-adịghị mma.
Hydroxypropyl methylcellulose ga-egbu oge nhazi nke ciment, na-ebelata nhazi na usoro siri ike nke ciment, ma gbasaa oge oghere nke ngwa agha ya.Otú ọ dị, mmetụta a adịghị mma maka ngwa agha na mpaghara oyi.
Dị ka ihe polymer nwere ogologo agbụ, hydroxypropyl methylcellulose nwere ike imeziwanye arụmọrụ njikọ ya na ihe ndabere ebe ọ na-ejigide ọdịnaya mmiri nke slurry nke ọma mgbe agbakwunyere na simenti.
Ihe ndị bụ isi nke HPMC na ngwa agha gụnyere: njide mmiri, ịgbatị, ịgbatị oge ntọala, ikuku ikuku, imeziwanye ike nkekọ tensile, wdg.
