Hydroxypropyl methylcellulose (HPMC)bụ polymer vasatail eji na ụlọ ọrụ dịka ọgwụ, ihe owuwu, ihe ịchọ mma, nri, na nlekọta onwe onye. Viscosity nke HPMC na-arụ ọrụ dị mkpa n'ịchọpụta na ọ dabara maka ngwa dị iche iche. A na-emetụta viscosity site na ịdị arọ molekụla, ogo ngbanwe, na itinye uche. Ịghọta akara ule viscosity kwesịrị ekwesị dị mkpa maka ịhọrọ HPMC ziri ezi maka mkpa ụlọ ọrụ akọwapụtara.
Nleta viscosity
A na-atụkarị viscosity nke AnxinCel®HPMC na ngwọta mmiri mmiri site na iji viscometer ntụgharị ma ọ bụ capillary. Ọkọlọtọ ule okpomọkụ bụ 20 Celsius C, na viscosity na-egosipụta na millipascal-sekọnd (mPa·s ma ọ bụ cP, centipoise). Akara ule dị iche iche nke HPMC nwere viscosities dị iche iche dabere na ngwa ha chọrọ.
Viscosity akara ule na ngwa ha
Tebụlụ dị n'okpuru na-akọwapụta akara ule viscosity nkịtị nke HPMC yana ngwa ha kwekọrọ:

Ihe na-emetụta viscosity
Ọtụtụ ihe na-emetụta viscosity nke HPMC:
Ibu Molecular:Ịdị arọ molekụla dị elu na-eduga n'ịbawanye viscosity.
Ogo nke nnọchi:Oke nke hydroxypropyl na methyl otu na-emetụta solubility na viscosity.
Ngwọta itinye uche:Ọnụ ọgụgụ dị elu na-ebute nnukwu viscosity.
Okpomọkụ:Viscosity na-ebelata na okpomọkụ na-abawanye.
Mmetụta pH:Ihe ngwọta HPMC kwụsiri ike n'ime pH nke 3-11 mana ọ nwere ike iweda ya na mpụga oke a.
Ọnụọgụ shia:HPMC na-egosipụta ihe ndị na-adịghị na Newtonian, nke pụtara viscosity na-ebelata n'okpuru nrụgide shiee.
Ngwa-Ntụle ndị akọwapụtara
Ngwa ahịa ọgwụ:A na-eji HPMC eme ihe n'ụdị ọgwụ maka ntọhapụ a na-achịkwa yana dịka ihe nkedo na mbadamba. A na-ahọrọ akara ule viscosity dị ala (100-400 mPa·s) maka mkpuchi, ebe a na-eji akara ngosi dị elu (15,000+ mPa·s) maka usoro ntọhapụ na-adịgide adịgide.
Ihe owuwu:AnxinCel®HPMC na-arụ ọrụ dị ka onye na-ejigide mmiri yana nrapado na ngwaahịa ndị sitere na ciment. Ogo viscosity dị elu (n'elu 4,000 mPa·s) dị mma maka imeziwanye arụmọrụ na ike njikọta.
Ihe ịchọ mma na nlekọta onwe onye:N'ime shampoos, lotions, na ude, HPMC na-arụ ọrụ dị ka ihe na-akpụ akpụ na stabilizer. Ọkara viscosity akara ule (400-1,500 mPa·s) na-enye nguzozi kachasị mma n'etiti udidi na ihe nrụpụta.
Ụlọ ọrụ nri:Dị ka ihe mgbakwunye nri (E464), HPMC na-eme ka udidi, nkwụsi ike, na njigide mmiri. Ogo viscosity dị ala (5-100 mPa·s) na-eme ka mgbasawanye nke ọma na-enweghị oke ibu.
