Hydroxypropyl methyl cellulose(hpmc)A na-ejikarị ya eme ihe na putty ntụ ntụ na viscosity nke 100000, ebe ngwa agha nwere ihe dị elu chọrọ maka viscosity na ekwesịrị ịhọrọ ya na viscosity nke 150000 maka iji ka mma. Ọrụ kachasị mkpa nkehydroxypropyl methyl cellulosebụ idowe mmiri, na-esote thickening. Ya mere, na putty ntụ ntụ, ọ bụrụhaala na a na-enweta njide mmiri na viscosity dị ala, ọ ga-ekwe omume. N'ikwu okwu n'ozuzu, ka viscosity dị elu, ka mma na-ejigide mmiri. Otú ọ dị, mgbe viscosity karịrị 100000, mmetụta nke viscosity na njide mmiri adịghị mkpa.

Ọkwa ihe owuwu JufuHydroxypropyl Methyl CelluloseN'ịbụ onye pụrụ iche site na viscosity, a na-ekewakarị ya na ụdị ndị a:

1. obere viscosity: 400 viscosity cellulose, tumadi eji maka onwe larịị ngwa agha. Viscosity dị ala, nke ọma na-erugharị, na mgbe mgbakwunye, ọ ga-achịkwa njigide mmiri dị n'elu. Ọbara na-apụtaghị ìhè, mbelata dị ntakịrị, na mgbawa na-ebelata. Ọ nwekwara ike iguzogide sedimentation, welie flowability na pumpability.
2. Ọkara na viscosity dị ala: 20000 ruo 50000 viscosity cellulose, nke a na-ejikarị eme ihe maka ngwaahịa gypsum na nkwonkwo nkwonkwo. Viscosity dị ala, ezigbo njide mmiri, arụ ọrụ dị mma, yana mgbakwunye mmiri dị ala,
3. Ọkara viscosity: 75000-100000 viscosity cellulose, tumadi eji maka ime na mputa mgbidi putty. Viscosity na-agafeghị oke, njide mmiri dị mma, yana akwa akwa akwa dị mma.
4. High viscosity: 150000 ka 200000 yuan, tumadi eji polystyrene urughuru mkpuchi ngwa agha ntụ ntụ ihe, vitrified micro bead mkpuchi ngwa agha na elu viscosity na mmiri njide. Ngwa ngwa ahụ adịghị mfe ịdaba ma kwụgidere, na-emeziwanye ihe owuwu.
N'ikwu okwu n'ozuzu, ka viscosity dị elu, ka mma na-ejigide mmiri. Ya mere, ọtụtụ ndị ahịa na-ahọrọ iji ọkara viscosity cellulose (75000-100000) kama ọkara obere viscosity cellulose (20000-50000) iji belata ego nke mgbakwunye na njikwa ego.
The viscosity nkeHPMCna-agbanwe agbanwe na okpomọkụ, na okwu ndị ọzọ, viscosity na-abawanye na mbelata okpomọkụ. Viscosity nke ngwaahịa pụtara na 2% ngwọta ya dị na okpomọkụ nke 20 degrees Celsius, na nsonaazụ ule ziri ezi.
N'ime ngwa dị iche iche, a ga-akwụ ụgwọ nlebara anya na mpaghara nwere nnukwu ọdịiche dị n'etiti okpomọkụ na oyi, na a na-atụ aro ka ị jiri viscosity dị ala na oyi. Ma ọ bụghị ya, ọ bụrụ na viscosity dị ala, viscosity nke cellulose ga-abawanye na ncha ga-adị arọ.
