Ọtụtụ ihe na-emetụta viscosity nke Hydroxypropyl Methyl Cellulose

Mgbe ịgbakwunye hydroxypropyl methylcellulose na ihe ndị sitere na ciment, ọ nwere ike itolite.Ọnụ ọgụgụ nke hydroxypropyl methylcellulose na-ekpebi ọchịchọ mmiri nke ihe ndị dabeere na ciment, ya mere ọ ga-emetụta mmepụta nke ngwa agha.

Ọtụtụ ihe na-emetụta viscosity nke hydroxypropyl methylcellulose:

1. Ihe dị elu nke polymerization nke cellulose ether, na-ebuwanye ibu arọ ya, na elu viscosity nke ngwọta mmiri;

2. Ihe dị elu nke oriri (ma ọ bụ itinye uche) nke cellulose ether, nke dị elu nke viscosity nke ngwọta mmiri ya.Otú ọ dị, ọ dị mkpa ịṅa ntị na ịhọrọ nri kwesịrị ekwesị n'oge ngwa iji zere ịṅụbiga mmanya ókè, nke ga-emetụta ọrụ nke ngwa agha na ihe.njirimara;

3. Dị ka ọtụtụ mmiri mmiri, viscosity nke cellulose ether ngwọta ga-ebelata na mmụba nke okpomọkụ, na elu nke ịta nke cellulose ether, ukwuu mmetụta nke okpomọkụ;

4. Hydroxypropyl methylcellulose ngwọta na-abụkarị pseudoplastic, nke nwere ihe onwunwe nke ịkpụ ntutu.Ọnụ ọgụgụ ka ukwuu n'oge ule, na-ebelata viscosity.

Ya mere, njikọ nke ngwa agha ga-ebelata n'ihi ike dị n'èzí, nke bara uru maka ịkwanye ihe owuwu nke ngwa agha, na-eme ka arụ ọrụ dị mma na njikọ nke ngwa agha n'otu oge.

Ihe ngwọta hydroxypropyl methylcellulose ga-egosi njirimara mmiri Newtonian mgbe ntinye uche dị ntakịrị na viscosity dị ala.Mgbe ntinye uche na-abawanye, ihe ngwọta ga-eji nwayọọ nwayọọ na-egosi njirimara mmiri mmiri pseudoplastic, na nke dị elu nke ntinye uche, otú ahụ ka pseudoplasticity na-apụta ìhè.
