Okwu Mmalite nke Hydroxyethyl Cellulose

Hydroxyethyl Cellulose (HEC) bụ polymer na-abụghị ionic, mmiri na-agbaze mmiri nke sitere na cellulose, polymer eke dị na osisi. A na-eji HEC eme ihe n'ọtụtụ ebe na ụlọ ọrụ dị iche iche n'ihi njirimara ya pụrụ iche na ngwa ngwa. Nke a bụ mmalite nke Hydroxyethyl Cellulose:

1. Ọdịdị kemịkalụ:

• HEC bụ cellulose ether gbanwere na otu hydroxyethyl. A na-emepụta ya site na imeghachi cellulose na ethylene oxide n'okpuru ọnọdụ a na-achịkwa. Ogo nke nnọchi (DS) nke otu hydroxyethyl na ọkpụkpụ azụ cellulose na-ekpebi njirimara na arụmọrụ nke HEC.

2. Njirimara anụ ahụ:

• HEC bụ ọcha na-acha ọcha, enweghị isi, na ntụ ntụ ma ọ bụ granule na-enweghị ụtọ. Ọ bụ soluble na mmiri na-etolite doro anya, viscous ngwọta na pseudoplastic rheology. Enwere ike imezi viscosity nke ngwọta HEC site n'ịgbanwe mkpokọta polymer, ogo nke nnọchi, na ịdị arọ molekụla.

3. Àgwà gbasara ọmụmụ:

• HEC na-egosiputa ihe njiri mara mma na akụrụngwa rheological, na-eme ka ọ bụrụ ihe na-eme ka ọ dị mma, stabilizer, na onye na-eme ihe nkiri na ngwa dị iche iche. Ọ na-enye omume pseudoplastic, nke pụtara na viscosity ya na-ebelata na ọnụ ọgụgụ shear, na-enye ohere maka ngwa dị mfe na ịgbasa.

4. Njide mmiri:

• HEC nwere ikike njigide mmiri dị elu, na-agbatị usoro hydration na nhazi dị ka ihe cimenti, adhesives, na mkpuchi. Ọ na-eme ka arụ ọrụ dịkwuo mma, nrapado, na ịtọ oge site n'ịkwado ọkwa mmiri na igbochi mmiri ozuzo ngwa ngwa.

5. Mbelata ọgba aghara n'elu:

• HEC na-ebelata esemokwu elu nke usoro mmiri na-adabere na ya, na-eme ka wetting, mgbasa, na ndakọrịta na mgbakwunye na ihe ndị ọzọ. Ihe onwunwe a na-eme ka arụmọrụ na nkwụsi ike nke usoro mmepụta, karịsịa na emulsions na suspensions.

6. Nkwụsi ike na ndakọrịta:

• HEC bụ kemịkalụ inert na dakọtara na ọtụtụ ihe ndị ọzọ, gụnyere surfactants, salts, acids, na alkalis. Ọ na-anọgide na-akwụsi ike n'elu oke pH na okpomọkụ, na-ahụ na arụmọrụ na-agbanwe agbanwe na nhazi na usoro dị iche iche.

7. Nhazi ihe nkiri:

• HEC na-emepụta ihe nkiri na-agbanwe agbanwe, nke na-apụta ìhè mgbe akpọnwụwo, na-enye ihe mgbochi na nrapado n'elu. A na-eji ya dị ka onye na-emepụta ihe nkiri na mkpuchi, adhesives, ngwaahịa nlekọta onwe onye, ​​​​na usoro ọgwụ, na-eme ka ịdịte aka na mma mara mma.

8. Ngwa:

• HEC na-achọta ngwa dị iche iche na ụlọ ọrụ dị ka ihe owuwu, agba na mkpuchi, nrapado, ihe ịchọ mma, ọgwụ, textiles, na nlekọta onwe onye. A na-eji ya dị ka thickener, rheology modifier, onye na-ejigide mmiri, stabilizer, onye na-eme ihe nkiri, na ihe nkedo n'ụdị dị iche iche na ngwaahịa.

9. Ihe gbasara gburugburu na nchekwa:

• A na-enweta HEC site na isi mmalite cellulose na-emegharị ma bụrụ ihe na-emebi emebi, na-eme ka ọ bụrụ enyi na gburugburu ebe obibi. A na-ewere ya na ọ dị mma maka iji ngwaahịa ndị ahịa ma na-agbaso ụkpụrụ iwu na ụkpụrụ dị mma na mba dị iche iche.

Na nchịkọta, Hydroxyethyl Cellulose (HEC) bụ a vasatail na ọtụtụ ebe a na-eji polima nwere magburu onwe ndim, mmiri njide, rheological, na film-akpụ Njirimara. Ngwa ya dị iche iche yana ndakọrịta na mgbakwunye ndị ọzọ na-eme ka ọ bụrụ ihe dị mkpa n'ọtụtụ usoro na ngwaahịa n'ofe ụlọ ọrụ.
