HPMC na-eji ihe ịchọ mma

Ihe ịchọ mma ọkwa HPMC Hydroxypropyl methylcellulose bụ polymer sịntetik nke a kwadebere site na mgbanwe kemịkalụ nke cellulose eke dị ka akụrụngwa. Cellulose ether bụ ihe sitere na cellulose eke, mmepụta cellulose ether na polymer sịntetik dị iche, ihe kachasị mkpa bụ cellulose, ogige polymer eke.

Njirimara ngwaahịa

1, ihe ndị sitere n'okike, obere mgbakasị ahụ, arụmọrụ dị nro, nchekwa na nchekwa gburugburu ebe obibi;

2, mmiri solubility na ndim: soluble na mmiri oyi, soluble na ụfọdụ organic solvents na mmiri na organic solvents ngwakọta;

3, ndim na viscosity: a obere ego nke ngwọta na-etolite a transperent viscous ngwọta, elu nghọta, kwụsiri ike ịrụ ọrụ, solubility mgbanwe na viscosity, ala na viscosity, ukwuu solubility; Mee ka nkwụsi ike na-erugharị sistemu nke ọma;

4, Nguzogide nnu: HPMC bụ polymer na-abụghị ionic, kwụsie ike na nnu metal ma ọ bụ ngwọta mmiri electrolyte organic;

5, ọrụ elu: ngwọta mmiri nke ngwaahịa ahụ nwere ọrụ elu, emulsification, colloid nchebe na nkwụsi ike ikwu na ọrụ na ihe ndị ọzọ; Esemokwu dị n'elu bụ 42 ~ 56Dyn / cm na 2% ngwọta mmiri.

6, PH nkwụsi ike: viscosity nke mmiri mmiri ngwọta kwụsiri ike na nso nke ph3.0-11.0;

7, njide mmiri: HPMC hydrophilic, agbakwunyere na slurry, mado, mado ngwaahịa iji nọgide na-enwe mmetụta njigide mmiri dị elu;

8, na-ekpo ọkụ gelation: mmiri ngwọta na-aghọ opaque mgbe kpụ ọkụ n'ọnụ na a ụfọdụ okpomọkụ, ruo mgbe e guzobere (poly) flocculation steeti, nke mere na ngwọta tụfuru viscosity. Ma ka ọ na-ajụ oyi, ọ ga-alaghachi na ngwọta mbụ ya. Okpomọkụ nke gelation na-adabere n'ụdị ngwaahịa, ntinye nke ngwọta na ọkụ ọkụ.

9, njirimara ndị ọzọ: ọmarịcha ihe nkiri akpụ, yana ọtụtụ nguzogide enzyme, mgbasa na njirimara adhesion;
