Nyocha na nnwale nke hydropyythyl methyl cellulose (hpmc)

Hydroxypyl Methyl Cellulose (HPMC) bụ polymer nke ọma na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, owuwu, na ihe ịchọ mma. Akwụkwọ a na-enye nyocha zuru oke na nnwale nke HPMC, na-ekpuchi ihe ndị na-egosipụta ihe omimi, Njirimara, usoro na-emepụta ihe, ngwa na usoro nyocha.

1.introdection:
Hydroxypyl Methyl Cellulose (HPMC) bụ mkpụrụ ndụ cellulose nwetara site na ịgwọ sellose na propylene oxide na methyl chloride. A na-ejikarị ya n'ụlọ ọrụ dị iche iche n'ihi ihe pụrụ iche ya, gụnyere ime ihe na-akpụ akpụ, na-akpụ akpụ ihe nkiri, njigide mmiri, na ike mmiri.

Ihe owuwu 2.uchemical na Njirimara HPMC:
HPMC bụ ihe na-abụghị nke eji eme ihe (C6H7O2 (oh) 3-x (och3) x) x) n, ebe x na-anọchite anya ogo nke dochie anya. Ogo ihe eji eme ihe na-emetụta Njirimara HPMC, gụnyere ọhụụ, sonyere na nkwụsi ike. HPMC na-agbanye mmiri na mmiri na ụfọdụ organic soncic, na-etolite ngụkọta nke na vious.

3.Mafacting usoro nke HPMC:
Usoro na-arụpụta usoro nke HPMC na-emetụta ogo cellose site na iji propylene oxide na methylch chloride. Enwere ike ịchịkwa ogo nke dochie anya site na idozi ọnọdụ mmeghachi omume, dị ka okpomọkụ, pH, na oge mmeghachi omume. Ihe si na HPMC ngwaahịa dị ọcha na usoro ihicha iji nweta nkọwapụta achọrọ.

4.AppPlications nke hpmc:
HPMC na-ahụ ngwa dị iche iche na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, owuwu, ihe ịchọ mma, yana ngwaahịa nlekọta onwe ya. Na ọgwụ, a na-eji HPMC mee ihe dị ka nke ukwu, ihe mgbochi, yana ndị nnọchi anya na mbadamba mbadamba. N'ime ụlọ ọrụ nri, a na-eji ya dị ka ihe na-eme ka ọ dị mma ma kwụsie ike na sauces, akwa na ngwaahịa mmiri ara ehi. Na-ewu ihe, a na-agbakwunye HPMC na ngwa agha, na-adọta ndị na-eme ihe ike iji meziwanye ọrụ na ngwa ọrụ. Ọzọkwa, a na-eji HPMC mee ihe na ihe ịchọ mma maka ihe nkiri ya na moisturizing akụrụngwa.

5.N'ihi na HPMC:
a. A na-ejikarị nyocha a na - achọpụta: FTURIR Transforn infrared (FTIR) a na - ejikarị ngụkọta ngụkọta (nmr) na - enyocha usoro kemịkalụ nke Hpmc ma gosipụta ogo ya.

b. Nyochaa nyocha nke Rheological: nnwale nke rhicals na-enyocha viscosity hpmc, omume gear, na akụrụngwa Shear-Thinning, nke dị mkpa maka ngwa ya n'ọtụtụ usoro.

c. A na-arụ ọrụ ikuku: ka carorimetry (DSC) na nyocha thermogravimetric (TGA) iji nyochaa nkwụsi ike nke HPMC na oke okpomọkụ, na-enyere aka ya maka ngwa maka ngwa.

d. A na-eji ọgwụ mmiri achọta ihe: A na-eji Karl Fisched titation iji chọpụta mmiri nke Hpmc, nke dị mkpa maka ịnọgide na-eguzosi ike na ndụ.

e. Nyochaa nhata: usoro laser na usoro microscopy na-arụ ọrụ iji tụọ nkesa nha nke nụ hpmc, na-ejide agbanwe agbanwe.

Nchịkwa HPMC:
Usoro njikwa dị mma maka HPMC gụnyere ule siri ike nke akụrụngwa, ihe nlere, ma rụchara ọrụ iji hụ na nnabata na nkọwapụta. Nke a na-agbanwe ule na-anwale na-anwale, ọmụmụ ihe mgbochi, na ịgbaso ezigbo ihe na-emepụta ihe (GMP).

Hydroxypyl Methyl Cellulose (HPMC) bụ polymer dị iche iche na ngwa dị iche iche n'ofe ụlọ ọrụ dị iche iche. Site na nyocha zuru oke na nnwale, enwere ike kpebie ihe na njiri mara nke HPMC, na-enyere aka ọnụ maka ngwa dị iche iche maka usoro nrụpụta.
