Na ala dị ala, ihe ngwọta nke HPMC na-eme ihe dị ka pseudoplastic na-agbadata mgbe ị na-akpali ma ọ bụ na-etinye nsogbu ngwa ngwa ma ọ bụ na-etinye nsogbu ngwa ngwa ma ọ bụ na-etinye nsogbu ngwa ngwa.
Enwere ike ịchịkwa viscosity HPMC site na idozi ogo oke ya na ogo nke dochie anya ya, nke na-eme ka ọ bụrụ mgbanwe dị iche iche na mpaghara dị iche iche. N'ihe banyere imezi nkwụsi ike nke ngwaahịa, HPMC nwere ike rụọ ọrụ site na usoro ndị a.
2. Usoro nke HPMC iji melite nkwụsi ike
Uzo na nke Rheolen
Dị ka nke ukwu, Hpmc nwere ike ịbawanye viscosity ma ọ bụ slurries ma ọ bụ slurries, si otú a na-abawanye vicesity na victity na-aba ụba nke usoro ahụ. Maka ụfọdụ ngwaahịa dị ka mkpuchi, dị ka mkpuchi, ihe ịchọ mma, na nkwụnye ego ọgwụ, HPMC nwere ike inye aka gbochie ụmụ irighiri ihe ma gbasaa nduzi nke ngwaahịa a. Na mgbakwunye, pseudoplastity nke hpmc na-enye ohere ngwaahịa ahụ iji kwụsie ike n'oge a na-echekwa ya na ụgbọ njem, ma na-eme ka ọ na-aga n'ihu ma na-eme ya.

Ngwongwo na-akpụ akpụ ihe nkiri na nsonaazụ nchekwa
Njirimara na-akpụ akpụ nke Hpmc na-enyere ya aka ịpụta ihe nkiri dị n'elu ngwaahịa ahụ mgbe ihichachara.

Igwe nkwụsi ike na mmeghachi omume ọnọdụ
HPMC na-egosi ezigbo nkwụsi ike n'oge okpomọkụ dị iche iche. Visascosity ya na osisi a na-emetụta mgbanwe okpomọkụ, mana viscosity vissethse na-aga n'ihu na ụlọ okpomọkụ. Na mgbakwunye, HPMC na-enwe nsogbu na-agbanwe agbanwe na ụfọdụ okpomọkụ, nke na-eme ka ọ bụrụ mmetụta pụrụ iche na sistemụ dị mkpa iji nwee mmetụta dị nro (dịka nri na ọgwụ).
3. Ngwa nke HPMC iji meziwanye ike na mpaghara dị iche iche
Ngwa na akụrụngwa ụlọ
Na-ewu ụlọ dịka cent gwongworo na tated nrapado, a na-ejikarị HPMC na-agbanwe agbanwe agbanwe agbanwe ma mụbaa na-agagharị na ọrụ owuwu. Na mgbakwunye, HPMC nke ọma na-egbu nke mmiri site na ịkpụ ihe nkiri mgbe ihichachara ma ọ bụ belata oge ọrụ n'oge owuwu, si otú ahụ na-eme ka nkwụsi ike nke ihe ahụ na ogo owuwu ahụ.
Ngwa na-akwado ọgwụ
Na ọgwụ na-emepụta ọgwụ, a na-eji HPMC mee ihe dị ka ihe dị ka nke ukwu, ihe nkiri gara aga ma na-achịkwa onye na-anabata ya. Mmetụta ya nke na-eme ka ọ dị ike ka ọ dị mma nke ihe ndị na-arụ ọrụ na nkwụsị ma ọ bụ emulsions ma gbochie esemokwu ọgwụ ma ọ bụ ọdịda. Na mgbakwunye, ihe nkiri na-eche nche nke HPMC nwere ike ijikwa ọnụego ọgwụgwụ na prowing oge nrụpụta nke ọgwụ.

N'ime ụlọ ọrụ nri, a na-eji HPMC na-ejikarị dị ka nke na-agbaze na emundrifier iji melite udiri na uto nri. Ike ya dị ukwuu nwere ike ịnagide mmiri ma gbatị ndụ na ngwaahịa. Dịka ọmụmaatụ, na ngwongwo ndị a na-eme achịcha, HPMC nwere ike igbochi mmiri site na-ewepụ ngwa ngwa ma melite oke na ịdị nro dị nro. Na mgbakwunye, enwere ike iji ihe nkiri HPMC nke HPMC mee ihe oriri iji gbochie oxidition na mmebi.
Ngwa Ngwaahịa kemile
Ngwaahịa kemịkalụ kwa ụbọchị dịka ihe mgbochi, ncha, na ngwaahịa nlekọta anụ ahụ, a na-ejikarị HPMC ahụ dị ka nke na-agbaze ma dịkwa mma. Ọ nwere ike ime ka ihe dị iche na ngwaahịa a, melite otu udiri udiri, mee ka emulsions ma ọ bụ ngwaahịa gel dị mfe itinye ma ọ bụ na ọ ga-eme ka ọ bụrụ nke zuru ezu.
