Ọtụtụ viscosity nkịtị nke HPMC na ngwa owuwu
1 Okwu mmalite
Hydroxypropyl Methylcellulose (HPMC) bụ ihe dị mkpa ụlọ ihe mgbakwunye na ọtụtụ-eji na ngwaahịa dị iche iche na ụlọ ihe ụlọ ọrụ, dị ka akọrọ-mix ngwa agha, putty ntụ ntụ, tile nrapado, wdg HPMC nwere ọtụtụ ọrụ dị ka ndim, mmiri njide, na ịrụ ọrụ ụlọ ka mma. Ọrụ ya na-adabere n'ụzọ dị ukwuu na viscosity ya. Isiokwu a ga-enyocha n'ụzọ zuru ezu na nkịtị viscosity ranges nke HPMC dị iche iche na-ewu ngwa na mmetụta ha na-ewu arụmọrụ.
2. Basic e ji mara HPMC
HPMC bụ cellulose ether na-abụghị ionic mmiri soluble nke enwetara site na mgbanwe kemịkalụ nke cellulose eke. Ọ nwere atụmatụ ndị a ma ama:
Ọkpụkpụ: HPMC nwere ike ịbawanye viscosity nke ihe ụlọ ma nye ezigbo ọrụ.
Njide mmiri: Ọ nwere ike belata evaporation nke mmiri nke ọma ma melite nrụpụta hydration mmeghachi omume nke ciment na gypsum.
Mmanya: Na-eme ka ihe ahụ dị nro n'oge a na-ewu ma dị mfe itinye.
Ihe na-emepụta ihe nkiri: Ihe nkiri a kpụrụ akpụ nwere ezigbo ike na mgbanwe ma nwee ike imeziwanye ihe elu nke ihe ahụ.
3. Ngwa nke HPMC na ihe owuwu ụlọ
Tile nrapado: Isi ọrụ HPMC na nrapado tile bụ imeziwanye ike njikọta na oge mepere emepe. Oke viscosity na-adịkarị n'etiti 20,000 na 60,000 mPa·s iji nye ezigbo njikọta na oge mepere emepe. Nnukwu viscosity HPMC na-enyere aka ịbawanye ike njikọta nke nrapado taịlị ma na-ebelata mwepu.
Putty ntụ ntụ: N'etiti putty ntụ ntụ, HPMC na-arụ ọrụ nke njide mmiri, mmanu mmanu na imeziwanye arụmọrụ. Viscosity na-adịkarị n'etiti 40,000 na 100,000 mPa·s. Viscosity dị elu na-enyere aka idowe mmiri dị na ntụ ntụ putty, na-eme ka oge ọrụ ya na-arụ ọrụ ya na ịdị nro dị elu.
Ngwakọta agwakọta akọrọ: A na-eji HPMC na ngwa ngwa ngwakọta akọrọ iji welie nrapado na njide mmiri. Ogologo viscosity nkịtị dị n'etiti 15,000 na 75,000 mPa·s. N'ọnọdụ dị iche iche ngwa, ịhọrọ HPMC nwere viscosity kwesịrị ekwesị nwere ike ịkwalite arụmọrụ njikọ yana njigide mmiri nke ngwa agha.
Ngwa ngwa na-edozi onwe ya: Iji mee ka ngwa agha na-ebuli onwe ya nwee mmetụta dị mma na nhazi onwe ya, viscosity nke HPMC na-adịkarị n'etiti 20,000 na 60,000 mPa·s. Ogo viscosity a na-eme ka ngwa agha ahụ nwee mmiri mmiri zuru oke na-enweghị emetụta ike ya mgbe ọ gwọchara ya.
Mkpuchi mkpuchi mmiri: Na mkpuchi mkpuchi mmiri, viscosity nke HPMC nwere mmetụta dị ukwuu na ihe mkpuchi na ihe na-emepụta ihe nkiri. A na-ejikarị HPMC nwere viscosity n'etiti 10,000 na 50,000 mPa·s iji hụ na mmiri dị mma na ihe na-emepụta ihe nkiri nke mkpuchi.
4. Nhọrọ nke HPMC viscosity
The viscosity nhọrọ nke HPMC tumadi dabere na ya ọrụ na kpọmkwem ngwa na ewu arụmọrụ chọrọ. N'ozuzu, ka viscosity nke HPMC na-adị elu, ka mmetụta na-esiwanye ike na njide mmiri dịkwuo mma, mana nnukwu viscosity nwere ike ịkpata nsogbu ụlọ. Ya mere, ịhọrọ HPMC na viscosity kwesịrị ekwesị bụ isi ihe iji hụ na nsonaazụ ụlọ.
Mmetụta siri ike: HPMC nwere viscosity dị elu nwere mmetụta siri ike karị ma dabara adaba maka ngwa chọrọ nrapado dị elu, dị ka gluu tile na ntụ ntụ.
Ịrụ ọrụ njide mmiri: HPMC nwere viscosity dị elu dị mma na njikwa mmiri ma dabara adaba maka ihe ndị dị mkpa iji jide mmiri ruo ogologo oge, dị ka ngwa ngwa mix mix.
Ịrụ ọrụ: Iji meziwanye ọrụ nke ihe onwunwe, viscosity na-agafeghị oke na-enyere aka imeziwanye ịdị mma nke ọrụ ihe owuwu, karịsịa na ngwa agha na-edozi onwe ya.
5. Ihe na-emetụta HPMC viscosity
Degree nke polymerization: Nke dị elu ogo nke polymerization nke HPMC, ka viscosity ka ukwuu. Ngwa dị iche iche chọrọ nhọrọ nke HPMC nwere ogo polymerization dị iche iche iji nweta nsonaazụ kacha mma.
Ngwọta Ngwọta: Ntinye uche nke HPMC na mmiri ga-emetụtakwa viscosity ya. N'ikwu okwu n'ozuzu, ka ntinye uche nke ngwọta dị elu, ka viscosity dịkwuo ukwuu.
Okpomọkụ: Okpomọkụ nwere mmetụta dị ukwuu na viscosity nke ngwọta HPMC. N'ozuzu, viscosity nke HPMC ngwọta na-ebelata ka okpomọkụ na-abawanye.
Dị ka ihe mgbakwunye dị mkpa n'ime ihe owuwu ụlọ, viscosity HPMC na-emetụta oke arụmọrụ na ojiji nke ngwaahịa ikpeazụ. Ogologo viscosity nke HPMC dịgasị iche n'etiti ngwa, mana ọ na-adịkarị n'etiti 10,000 na 100,000 mPa·s. Mgbe ị na-ahọrọ HPMC kwesịrị ekwesị, ọ dị mkpa iji nlezianya tụlee mmetụta nke viscosity na ihe onwunwe dị ka ihe ngwa ngwa chọrọ na ọnọdụ ihe owuwu si dị, iji nweta mmetụta kachasị mma.
