Jiri HEC Hydroxy Ethyl Cellulose mee ka ncha mmiri dị arọ

N'ime ụbọchị ole na ole gara aga, ụmụ akwụkwọ enweela nsogbu n'ihi oke ncha mmiri mmiri. N'ezie, n'eziokwu, ọ na-esiri m ike itocha ncha mmiri mmiri. Agbanyeghị, akụzikwara m na klaasị na enwere ọtụtụ ụzọ isi nweta nke a. The bekee na ndim ụzọ ewebata taa nwere ike dị ka ọzọ.

njirimara:
A na-akpọkwa HEC Hydroxy ethyl cellulose dị ka macromolecular cellulose (ma ọ bụ polymer macromolecular)

A na-agbanwe akụrụngwa sitere na eriri osisi eke ma nwee mmetụta na-amị amị mara mma!
Ọ bụ ntụ ntụ ọcha (edo edo), ihe na-abụghị ionic mmiri-soluble polymer compound, nke enwere ike iji dị ka ihe na-eme ka ọ dị arọ na onye na-akwụsịtụ.
Ọ dị mfe ịrụ ọrụ na mmiri ọkụ karịa na mmiri oyi, ọ ghaghị ịnọgide na-akpali akpali, a na-echekwa uru pH n'elu 6, nke dị mfe ịgbari.
A na-ejikarị ngwaahịa dị iche iche mara mma na ihicha, ọ nwere mmetụ yiri hyaluronic acid, ngwaahịa emechara na-apụta ìhè ma nwee nguzogide acid kachasị elu.

Ncha mmiri na-agbakọ:
Jiri 1-2% ịta ahụhụ, tinye 1g nke ethyl cellulose na 99g nke mmiri distilled ma kpalie, mgbe ị na-eche, biko kpalie ya ọ bụla 5 ~ 10 nkeji, ekwela ka ntụ ntụ dozie, ruo mgbe gel bụ uzo, wee tinye mix ọma. na ncha mmiri mmiri.

Ngwa ịchọ mma:
1. Ethyl cellulose nwere ike iji mee ka transperent colloid, nke a na-ejikarị na-emepụta ihe dị elu, gel, mkpuchi ihu na ncha ntutu.
2. Enwere ike iji ya dị ka onye na-akwụsịtụ ma na-eme ka ọ dị arọ maka ngwaahịa ude iji dozie ogo Q na nkwụsi ike nke ude.

Ntuziaka maka ojiji:
1. Mmiri ọkụ na-adị mfe karị
2. Chere ihe karịrị 20 nkeji mgbe mmiri oyi na-agba, ma kpalie ọ bụla 5 ~ 10 nkeji mgbe ị na-echere.
3. Ọnụ ego eji eme ihe: 0.5 ~ 2% isi; 3-5% gel.
4. PH nso: acid na-eguzogide PH3 na 25% mmanya.
5. Ndị ọzọ: akụrụngwa ionic ndị ọzọ agaghị emetụta ya.
