Tekanyo ea Viscosity
The viscosity ea AnxinCel®HPMC e atisa ho lekanyetsoa ka litharollo tse nang le metsi a mangata ho sebelisoa rotational kapa capillary viscometer. Mocheso o tloaelehileng oa teko ke 20 ° C, 'me viscosity e hlahisoa ka millipascal-seconds (mPa·s kapa cP, centipoise). Limaraka tse fapaneng tsa HPMC li na le li-viscosity tse fapaneng ho latela ts'ebeliso ea tsona e reriloeng.
Lihlopha tsa Viscosity le Lisebelisoa tsa tsona
Tafole e ka tlase e bonts'a limaraka tse tloaelehileng tsa viscosity tsa HPMC le lits'ebetso tse tsamaellanang le tsona:

Lintlha tse Amang Viscosity
Lintlha tse 'maloa li susumetsa viscosity ea HPMC:
Boima ba Molek'hule:Boima bo phahameng ba limolek'hule bo lebisa ho ho eketseha ha viscosity.
Degree ea Phapanyetsano:Karolelano ea lihlopha tsa hydroxypropyl le methyl e ama ho solubility le viscosity.
Maikutlo a Tharollo:Likhakanyo tse phahameng li baka viscosity e kholo.
Mocheso:Viscosity e fokotseha ka mocheso o ntseng o eketseha.
pH Sensitivity:Litharollo tsa HPMC li tsitsitse ka har'a mefuta ea pH ea 3-11 empa li ka senyeha ka ntle ho mefuta ena.
Sekhahla sa Shear:HPMC e bonts'a thepa ea phallo e seng ea Newtonian, ho bolelang hore viscosity e ea fokotseha tlasa khatello ea ho kuta.
Maikutlo a khethehileng a Kopo
Meriana:HPMC e sebelisoa mefuteng ea litlhare bakeng sa tokollo e laoloang le joalo ka se tlamella matlapa. Limaraka tse tlase tsa viscosity (100–400 mPa·s) li ratoa bakeng sa ho roala, ha limaraka tse holimo (15,000+ mPa·s) li sebelisoa bakeng sa litlolo tse sa khaotseng.
Kaho:AnxinCel®HPMC e sebetsa e le ntho ea ho boloka metsi le sekhomaretsi lihlahisoa tse entsoeng ka samente. Limaraka tse phahameng tsa viscosity (ka holimo ho 4,000 mPa·s) li loketse ho ntlafatsa ts'ebetso le matla a ho kopanya.
Litlolo le Tlhokomelo ea Motho:Ka har'a li-shampoo, litlolo, le litlolo, HPMC e sebetsa joalo ka setepi le se matlafatsang. Limaraka tse mahareng tsa viscosity (400–1,500 mPa·s) li fana ka tekano e nepahetseng lipakeng tsa sebopeho le thepa ea phallo.
Indasteri ea Lijo:Joalo ka kenyelletso ea lijo (E464), HPMC e ntlafatsa sebopeho, botsitso le ho boloka mongobo. Limaraka tse tlase tsa viscosity (5–100 mPa·s) li netefatsa phallo e nepahetseng ntle le ho tenya ho feteletseng.
