A na-ejikarị hydroxypropyl methylcellulose eme ihe na ntụ ntụ nke nwere viscosity nke 100,000, ebe ngwa agha nwere ihe dị elu nke chọrọ viscosity, ya mere a ga-eji ya na viscosity nke 150,000. Ọrụ kachasị mkpa nke hydroxypropyl methylcellulose bụ njide mmiri, na-esote thickening. Ya mere, na putty ntụ ntụ, ọ bụrụhaala na a na-enweta njide mmiri, viscosity dị ala. N'ikwu okwu n'ozuzu, ka viscosity dị ukwuu, ka mma na-ejide mmiri, ma mgbe viscosity karịrị 100,000, viscosity enwechaghị mmetụta na njide mmiri.
Dị ka viscosity si kwuo, a na-ekewa hydroxypropyl methylcellulose n'ime ụdị ndị a:
1. obere viscosity: 400 viscosity cellulose, tumadi eji maka onwe-leveling ngwa agha.
Ọ nwere obere viscosity na ezigbo fluidity. Mgbe agbakwunyere, ọ ga-achịkwa njigide mmiri nke elu, ọbara ọgbụgba adịghị egosi, nkwụsịtụ dị ntakịrị, mgbawa na-ebelata, ọ pụkwara iguzogide sedimentation ma welie mmiri na pumpability.
2. Ọkara na obere viscosity: 20,000-50,000 viscosity cellulose, nke a na-ejikarị na ngwaahịa gypsum na ndị na-emepụta ihe.
Viscosity dị ala, njigide mmiri dị elu, arụ ọrụ dị mma, obere mmiri agbakwunyere,
3. Ọkara viscosity: 75,000-100,000 viscosity cellulose, tumadi eji maka ime na mputa mgbidi putty.
Viscosity na-agafeghị oke, njide mmiri dị mma, ihe owuwu dị mma na ihe eji eme ihe
4. High viscosity: 150,000-200,000, tumadi eji polystyrene urughuru mkpuchi ngwa agha roba ntụ ntụ, vitrified microbead mkpuchi ngwa agha.
Site na viscosity dị elu na njigide mmiri dị elu, ngwa agha ahụ adịghị mfe ịkwanye ash na sag, nke na-eme ka owuwu ahụ dịkwuo mma.
N'ikwu okwu n'ozuzu, ịdị elu nke viscosity dị elu, ka mma na-ejigide mmiri, ọtụtụ ndị ahịa ga-ahọrọ iji cellulose ọkara-viscosity (75,000-100,000) kama obere viscosity cellulose (20,000-50,000) iji belata ego agbakwunyere, na mgbe ahụ. ego njikwa
