Ọtụtụ Ihe Ndị Na-emetụta Viscosity nke Hydroxypropyl Methyl Cellulose

Mgbe etinyere hydroxypropyl methylcellulose na ihe ndị e ji simenti mee, ọ nwere ike ịka njọ. Ọnụọgụ hydroxypropyl methylcellulose na-ekpebi mkpa mmiri nke ihe ndị e ji simenti mee, yabụ ọ ga-emetụta mmepụta nke simenti.

Ọtụtụ ihe na-emetụta viscosity nke hydroxypropyl methylcellulose:

1. Ka oke polymerization nke cellulose ether dị elu, otú ahụ ka ibu ya dị arọ karịa, na oke viscosity nke mmiri mmiri dị elu;

2. Ka ọnụ ọgụgụ cellulose ether dị elu, otú ahụ ka mmiri mmiri ya si jupụta. Agbanyeghị, ọ dị mkpa ịṅa ntị n'ịhọrọ oke oriri kwesịrị ekwesị n'oge a na-etinye ya iji zere oke oriri, nke ga-emetụta ọrụ nke ngwa agha na simenti. njirimara;

3. Dịka ọtụtụ mmiri mmiri, viscosity nke ihe ngwọta cellulose ether ga-ebelata ka okpomọkụ na-arị elu, ka ọnụ ọgụgụ cellulose ether na-arị elu, otú ahụ ka mmetụta nke okpomọkụ na-abawanye;

4. Mmiri Hydroxypropyl methylcellulose na-abụkarị pseudoplastic, nke nwere ihe onwunwe nke ịkpụ shear. Ka ọnụego shear na-abawanye n'oge nnwale ahụ, otú ahụ ka viscosity na-ebelata.

Ya mere, njikọ nke ngwa agha ga-ebelata n'ihi ike mpụga, nke bara uru maka ịkpụcha ngwa agha, na-eme ka ọ dị mma ịrụ ọrụ ma jikọta ngwa agha n'otu oge ahụ.

Ngwọta hydroxypropyl methylcellulose ga-egosi njirimara mmiri Newtonian mgbe ntinye ahụ dị obere nke ukwuu ma viscosity ya dị ala. Mgbe ntinye ahụ mụbara, ngwọta ahụ ga-egosi njirimara mmiri pseudoplastic nwayọ nwayọ, ka ntinye ahụ dịkwuo elu, otú ahụ ka pseudoplasticity ahụ na-apụta ìhè.
