3. Kedu ụdị hydroxypropyl methylcellulose (HPMC) dị?Kedu ihe dị iche n'etiti ha?
Enwere ike kewaa HPMC n'ime ngwa ngwa na soluble na-ekpo ọkụ.Ngwa ngwa soluble ngwaahịa, gbasaa ngwa ngwa wee pụọ n'ime mmiri na mmiri oyi.N'oge a, mmiri mmiri enweghị viscosity dị ka HPMC na-agbasasị na mmiri na-adịghị agbaze.Mgbe ihe dị ka nkeji 2 gachara, viscosity nke mmiri mmiri ji nwayọọ nwayọọ na-abawanye, na-akpụ gel viscous doro anya.Ngwaahịa na-ekpo ọkụ na-ekpo ọkụ nwere ike ịgbasa ngwa ngwa na mmiri ọkụ ma na-apụ n'anya na mmiri ọkụ.Ka okpomọkụ na-adaba na ụfọdụ okpomọkụ, viscosity na-apụta nke nta nke nta ruo mgbe a na-emepụta gel viscous doro anya.

Enwere ike iji ụdị agbaze ọkụ na-ekpo ọkụ naanị na ntụ ntụ na ngwa ngwa.Na gluu mmiri mmiri na agba, caking na-eme na enweghị ike iji ya.Ụdị ngwa ngwa ahụ nwere ngwa ngwa dị iche iche ma nwee ike iji ya mee ihe na ntụ ntụ na ngwa ngwa yana na gluu mmiri na agba.

(1) Specific gravity: Ka ike ndọda dị elu dị elu, ka mma ahụ ka mma.
(2) Ọcha: Ọtụtụ ngwaahịa dị mma nwere ezigbo ọcha.Ewezuga ndị nwere ihe na-acha ọcha agbakwunyere.Ihe na-acha ọcha nwere ike imetụta àgwà.
(3) Ịdị mma: Ka ịdị mma na-adịwanye mma, otú ahụ ka ọ dị mma.Ịdị mma nke HPMC anyị na-abụkarị ntupu 80 na ntupu 100, ntupu 120 dịkwa.
(4) Mbufe: Tinye HPMC n'ime mmiri ka ọ bụrụ gel transperent wee hụ nnyefe ya.Ka ukwuu na-ebufe ya, ihe na-adịghị edozi ahụ.Vetikal reactors na-enwekarị mma transmittance na kehoraizin reactors nwere ogbenye transmittance, ma nke a apụtaghị na mmepụta àgwà nke vetikal reactors dị mma karịa nke ndị ọzọ mmepụta ụzọ.E nwere ọtụtụ ihe na-ekpebi àgwà ngwaahịa ahụ na ndị na-emepụta ihe na-emepụta ihe, nke nwere nnukwu hydroxypropyl na ọdịnaya hydroxypropyl dị elu, nke kacha mma maka njide mmiri.
