Kedu ihe bụ viscosity nke hydroxypropyl methylcellulose hpmc?

Putty ntụ ntụ maka mgbidi ime n'ozuzu nwere viscosity nke 100,000. Ngwunye ciment nwere ihe dị elu chọrọ maka mmezi, na viscosity nke 150,000 dị mfe iji. Na mgbakwunye, ọrụ kachasị mkpa nke HPMC bụ ịgbachi mmiri, na-esote thickening. Na ntụ ntụ putty, ọ bụrụ na njide mmiri dị mma na viscosity dị ala (7-80,000), ọ pụkwara inwe viscosity dị elu nke okike na njigide mmiri dị mma. Mgbe viscosity karịrị 100,000, viscosity enwechaghị mmetụta na njide mmiri.

Gịnị bụ isi mmetụta nkeHPMC na putty ntụ ntụ, na ma organic chemistry na-eme?

HPMC na-arụ ọrụ atọ nke ịgbara mmiri, njigide mmiri na iwu na ntụ ntụ.

Ọkpụkpụ: Methylcellulose nwere ike itinye uche ya na ihe na-ese n'elu mmiri, mmiri mmiri iji nọgide na-arụ ọrụ otu yana na-agbanwe agbanwe ma gbochie ịgbado mmiri.

Njide mmiri: Mgbidi mgbidi dị n'ime na-akpọnwụ nwayọọ nwayọọ, na calcium lime agbakwunyere na-egosipụta na iji mmiri eme ihe.

Ihe owuwu injinia: Methyl cellulose nwere mmetụta mmanye mmanu, nke nwere ike ime ka ntụ ntụ putty nwee usoro injinia mara mma.

HPMC adịghị etinye aka na mgbanwe kemịkalụ niile kama ọ bụ naanị na mgbakwunye. Putty ntụ ntụ, na mgbidi, bụ mgbanwe kemịkalụ, n'ihi na e nwere mgbanwe kemịkal ọhụrụ, ntụ ntụ na-esi na mgbidi pụta, na-egweri ntụ ntụ, na-ejigharị ọzọ n'ihi na e mepụtala ihe ọhụrụ chemical (calcium carbonate).

Isi mmiri calcium iji uyi bụ: Ca (oh) 2, Cao na obere ego nke Caco3 ogige, Caoh2oCa (oh) 2-Ca (oh) 2caco3h2o wayo nwere ike converted n'ime calcium bicarbonate na mmiri na gas, mgbe mpc bụ. naanị mmiri soluble Calcium ijiji ash bụ ike echiche, nke n'onwe ya adịghị ekere òkè ọ bụla echiche.

Kedu ihe kwesịrị ịṅa ntị na ngwa ngwa nke mmekọrịta dị n'etiti viscosity na okpomọkụ nke HPMC?

Viscosity nke HPMC dabara na ọnọdụ okpomọkụ, na okwu ndị ọzọ, viscosity na-abawanye site na mbelata okpomọkụ. The viscosity nke ngwaahịa, viscosity nke ngwaahịa pụtara na ya 2% ngwọta bụ na okpomọkụ nke 20 degrees Celsius, na ule pụta.

N'ime ngwa ndị a kapịrị ọnụ, a ga-akwụ ụgwọ nlebara anya na mpaghara nwere nnukwu ọdịiche dị n'etiti okpomọkụ na oyi, na a na-atụ aro ka ị jiri viscosity dị ala na oyi. Ma ọ bụghị ya, viscosity dị ala, viscosity nke cellulose ga-abawanye, na ncha ga-adị arọ.

Ọkara viscosity: 75000-100000 kwesịrị ekwesị maka putty ntụ ntụ
Ihe kpatara ya: ezigbo njide mmiri

Nnukwu viscosity: 150000-200000 dabara adaba maka ngwa agha mkpuchi nke polystyrene na ngwa mkpuchi inorganic.
Ihe kpatara ya: viscosity dị elu, mwepụ siri ike nke ngwa ngwa ciment, nkwụsị nke gloss, ihe owuwu ka mma.
