Nnwale viscosity Cellulose Ether

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 nkọwapụta 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 mkpịsị aka 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 na-emepụta cellulose ether nyere maka nyocha viscosity, dịka usoro nwere ike ịdịgasị iche dabere na ụdị cellulose ether na ngwa e bu n'obi.
