Nnwale viscosity Cellulose Ether

The viscosity nkecellulose ethers, dị ka Hydroxypropyl Methylcellulose (HPMC) ma ọ bụ Carboxymethyl Cellulose (CMC), bụ ihe dị mkpa nke nwere ike imetụta arụmọrụ ha na ngwa dị iche iche. Viscosity bụ ihe nleba anya nke mmiri na-eguzogide mmiri, ihe ndị dị ka itinye uche, okpomọkụ, na ogo ngbanwe nke cellulose ether nwere ike imetụta ya.

Nke a bụ ntụzịaka izugbe maka otu esi eme nnwale viscosity maka ethers cellulose:

Ụzọ Brookfield Viscometer:

The Brookfield viscometer bụ ngwá ọrụ a na-ejikarị atụta viscosity nke mmiri. Usoro ndị a na-enye ndepụta bụ isi maka ịme ule viscosity:

1. Nkwadebe ihe atụ:
   • Kwadebe mkpokọta amara nke ngwọta ether cellulose. Ntinye uche ahọpụtara ga-adabere na ihe achọrọ nke ngwa ahụ.
2. Nhazi okpomọkụ:
   • Gbaa mbọ hụ na a haziri ihe nlele ahụ na okpomọkụ nnwale achọrọ. Viscosity nwere ike ịdabere na okpomọkụ, yabụ ịnwale na ọnọdụ okpomọkụ a na-achịkwa dị mkpa maka nha ziri ezi.
3. Nhazi
   • Mepụta viscometer Brookfield site na iji mmiri ngbanwe ọkọlọtọ iji hụ na ọgụgụ ziri ezi.
4. Na-ebu ihe nlele ahụ:
   • Bunye ihe ngwọta cellulose ether zuru oke n'ime ụlọ viscometer.
5. Nhọrọ nke Spindle:
   • Họrọ mkpịsị mkpịsị kwesịrị ekwesị dabere na nso viscosity a na-atụ anya na nlele ahụ. A na-enweta spindle dị iche iche maka ọkwa dị ala, ọkara na elu viscosity.
6. Ntụ:
   • Tinye mkpịsị ugodi n'ime ihe nlele ahụ, wee malite viscometer. Mkpanaka ahụ na-atụgharị na ọsọ ọsọ mgbe niile, a na-atụkwa nguzogide ntụgharị.
7. Data ndekọ:
   • Dekọọ agụ viscosity site na ihe ngosi viscometer. Otu nha na-abụkarị centipoise (cP) ma ọ bụ millipascal-sekọnd (mPa·s).
8. Tinyegharịa nha:
   • Mepụta ọtụtụ nha iji hụ na mmụgharị. Ọ bụrụ na viscosity na-adịgasị iche ka oge na-aga, nha ọzọ nwere ike ịdị mkpa.
9. Nyocha data:
   • Nyochaa data viscosity na ọnọdụ nke ngwa chọrọ. Ngwa dị iche iche nwere ike ịnwe ebumnuche viscosity akọwapụtara.

Ihe na-emetụta viscosity:

1. itinye uche:
   • Ọnụ ọgụgụ dị elu nke ngwọta ether cellulose na-ebutekarị viscosities dị elu.
2. Okpomọkụ:
   • Viscosity nwere ike inwe mmetụta okpomọkụ. Okpomọkụ dị elu nwere ike ibelata viscosity.
3. Ogo nke nnọchi:
   • Ogo nke nnọchi nke cellulose ether nwere ike imetụta njupụta ya na, n'ihi ya, viscosity ya.
4. Ọnụọgụ shia:
   • Viscosity nwere ike ịdịgasị iche na ọnụ ọgụgụ shear, na viscometers dị iche iche nwere ike ịrụ ọrụ na ọnụ ọgụgụ shear dị iche iche.

Na-agbaso ntuziaka akọwapụtara nke onye nrụpụta cellulose ether nyere maka nnwale viscosity, n'ihi na usoro nwere ike ịdịgasị iche dabere n'ụdị ether cellulose na ngwa ebumnuche ya.
