Mofuta oa indasteri oa hydroxypropyl methylcellulose o sebelisetsoang ho etsa seretse (mona o bua ka selulose e hloekileng, ntle le lihlahisoa tse fetotsoeng) o khetholloa ka viscosity, 'me lihlopha tse latelang li sebelisoa hangata (yuniti ke viscosity):
Viscosity e tlase: 400
E sebelisoa haholo-holo bakeng sa seretse sa ho ikemela;viscosity e tlase, le hoja ho boloka metsi ho fokola, empa thepa ea ho leka-lekanya e ntle, 'me seretse se teteaneng se phahame.
Viscosity e bohareng le e tlase: 20000-40000
Haholo-holo e sebelisoa bakeng sa likhomaretsi tsa lithaele, li-caulking agents, li-anti-cracking mortars, li-thermal insulation bonding mortars, joalo-joalo;kaho e ntle, metsi a fokolang, seretse se phahameng sa seretse.
Viscosity e bohareng: 75000-100000
Haholo-holo e sebelisetsoang putty;ho boloka metsi hantle.
Viscosity e phahameng: 150000-200000
E sebelisoa haholo-holo bakeng sa polystyrene particle thermal insulation mortar rabara phofo le vitrified microbead thermal insulation seretse;viscosity e phahame, seretse ha se bonolo ho oela, 'me mohaho oa ntlafatsoa.
Litšebelisong tse sebetsang, hoa lokela ho hlokomeloa hore libakeng tse nang le phapang e kholo ea mocheso pakeng tsa lehlabula le mariha, ho kgothaletswa ho sebelisa viscosity e batlang e le tlaase nakong ea mariha, e leng se loketseng ho haha.Ho seng joalo, ha mocheso o le tlase, viscosity ea cellulose e tla eketseha, 'me letsoho le tla ba boima ha le senya.
Ha re bua ka kakaretso, ha viscosity e phahame, ho boloka metsi ho molemo.Ha ho nahanoa ka litšenyehelo, lifeme tse ngata tse omeletseng tsa seretse sa phofo li nkela sebaka se mahareng le se tlase sa viscosity cellulose (20000-40000) ka selulose e bohareng ea viscosity (75000-100000) ho fokotsa palo ea tlatsetso.Lihlahisoa tsa seretse li lokela ho khethoa ho bahlahisi ba kamehla le ho tsejoa.
Kamano pakeng tsa viscosity le mocheso oa HPMC:
The viscosity ea HPMC e inversely tekano le mocheso, ke hore, viscosity eketseha ha mocheso fokotseha.Viscosity ea sehlahisoa seo hangata re buang ka sona se bolela sephetho sa tlhahlobo ea tharollo ea metsi a 2% mochesong oa likhato tse 20 tsa Celsius.
