Kedu ihe bụ HydroxypropylMethylcellulose

Hydroxypropyl Methylcellulose (HPMC) bụ ether cellulose na-abụghị ionic nke sitere na cellulose eke. A na-emepụta ya site na mgbanwe kemịkalụ nke cellulose, nke a na-enwetakarị site na osisi pulp ma ọ bụ eriri owu. A na-eji HPMC eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche n'ihi njirimara na ngwa ya dị iche iche.

Ọdịdị kemịkal:

• HPMC nwere ọkpụkpụ azụ cellulose nwere hydroxypropyl na methyl nke etinyere na otu hydroxyl nke nkeji glucose. Ogo nke nnọchi (DS) na-egosi nkezi ọnụọgụ hydroxypropyl na methyl otu glucose n'ime agbụ cellulose. Usoro kemịkalụ nke HPMC na-enye ihe pụrụ iche dị ka mmiri solubility, ike imepụta ihe nkiri, na mgbanwe viscosity.

Njirimara na njirimara:

1. Mmiri Solubility: HPMC bụ soluble na mmiri oyi, mmiri ọkụ, na ụfọdụ organic mgbaze dị ka methanol na ethanol. Solubility na-adabere na ihe ndị dị ka ogo nke nnọchi, ịdị arọ molekụla, na okpomọkụ.
2. Njikwa viscosity: Ihe ngwọta HPMC na-egosipụta àgwà pseudoplastic ma ọ bụ shear-thinning, ebe viscosity na-ebelata na-abawanye ọnụ ọgụgụ shear. A na-eji ya eme ihe n'ọtụtụ ebe dị ka thickener, rheology modifier, na stabilizer n'ụdị dị iche iche iji chịkwaa viscosity na melite udidi.
3. Nhazi ihe nkiri: HPMC nwere ike ịmepụta ihe nkiri transperent ma ọ bụ translucent mgbe ihicha. Ihe nkiri ndị a nwere ezigbo mmachi, mgbanwe, na ihe mgbochi, na-eme ka HPMC dị mma maka mkpuchi, ihe nkiri, na mbadamba ọgwụ.
4. hydration na ọzịza: HPMC nwere oke mmekọrịta maka mmiri ma nwee ike ịmịkọrọ ma na-ejigide oke mmiri. Mgbe agbasasị na mmiri, HPMC hydrates na-etolite gels na pseudoplastic eruba Njirimara, welie mmiri njigide na workability na formulations.
5. Inertness kemịkalụ: HPMC bụ kemịkalụ inert na ọ naghị enweta mmeghachi omume kemịkal dị ukwuu n'okpuru nhazi na ọnọdụ nchekwa nkịtị. Ọ dakọtara na ọtụtụ ihe ndị ọzọ na ihe mgbakwunye na-eji na-emepụta ihe.

Ngwa:

• Pharmaceuticals: Ọ ​​dị na mbadamba mbadamba, capsules, ointments, nkwusioru, na usoro mwepụta a na-achịkwa.
• Mwube: Mgbakwunye na nrapado tile, ngwa agha, ndị na-atụgharị, plasta, na ogige ndị na-edozi onwe ha iji meziwanye njide mmiri, ịrụ ọrụ, na nrapado.
• Agba na mkpuchi: Thickener, stabilizer, na onye na-emepụta ihe nkiri na agba latex, emulsion polymerization, na mkpuchi iji chịkwaa viscosity na ịkwalite ihe nkiri.
• Nri na ihe ọṅụṅụ: ihe na-eme ka ọ dị arọ, emulsifier, na stabilizer na sauces, uwe, ofe, desserts, na ihe ọṅụṅụ iji melite ọdịdị na nkwụsi ike.
• Nlekọta onwe onye na ihe ịchọ mma: Thickerer, onye na-akwụsịtụ ihe, na onye na-emepụta ihe nkiri na shampoos, conditioners, creams, lotions, na masks iji kwalite arụmọrụ ngwaahịa na ịchọ mma.

A na-eji Hydroxypropyl Methylcellulose (HPMC) kpọrọ ihe maka ịdị mma ya, nchekwa ya na ịdị irè ya na ngwa ụlọ ọrụ dị iche iche, na-enye aka n'iji ya eme ihe n'ofe ọtụtụ ụlọ ọrụ.
