Njirimara anụ ahụ nke Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) bụ polymer soluble mmiri nke sitere na cellulose. A na-ejikarị ya eme ihe na ụlọ ọrụ dị iche iche n'ihi njirimara anụ ahụ pụrụ iche. Ụfọdụ n'ime njirimara anụ ahụ dị mkpa nke hydroxyethyl cellulose gụnyere:

1. Solubility: HEC bụ soluble na mmiri na-emepụta doro anya, viscous ngwọta. Solubility nke HEC nwere ike ịdịgasị iche dabere na ihe ndị dị ka ogo nke nnọchi (DS) nke otu hydroxyethyl na ịdị arọ molekul nke polymer.
2. Viscosity: HEC na-egosiputa viscosity dị elu na ngwọta, nke nwere ike gbanwee site na ihe dị iche iche dị ka ntinye uche polymer, okpomọkụ, na nha nha. A na-ejikarị ihe ngwọta HEC eme ihe dị ka ihe na-eme ka ọ dị arọ n'ọtụtụ ngwa, gụnyere agba, nrapado, na ngwaahịa nlekọta onwe onye.
3. Ikike Ịme Ihe nkiri: HEC nwere ikike ịmepụta ihe nkiri na-agbanwe agbanwe na nke jikọrọ ọnụ mgbe ihicha. A na-eji ihe a eme ihe na ngwa dịka mkpuchi maka mbadamba nkume na capsules na ọgwụ, yana n'ihe ịchọ mma na ngwaahịa nlekọta onwe onye.
4. Njide mmiri: HEC nwere ezigbo njigide mmiri, na-eme ka ọ bụrụ polymer na-edozi mmiri dị irè maka iji ihe owuwu dị ka ngwa agha, grouts, na nsụgharị. Ọ na-enyere aka igbochi mmiri ozuzo ngwa ngwa n'oge ngwakọta na ngwa ngwa, na-eme ka ọrụ na-arụ ọrụ na adhesion dịkwuo mma.
5. Thermal Stability: HEC na-egosipụta ezigbo nkwụsi ike nke okpomọkụ, na-ejigide ihe onwunwe ya n'elu oke okpomọkụ. Ọ nwere ike iguzogide okpomọkụ nhazi zutere na ụlọ ọrụ dị iche iche na-enweghị mmebi dị ukwuu.
6. Nkwụsi ike pH: HEC kwụsiri ike n'elu oke pH dị obosara, na-eme ka ọ dabara adaba maka iji ya mee ihe na ọnọdụ acidic, nnọpụiche ma ọ bụ alkaline. Ngwongwo a na-enye ohere maka iji ya na ngwa dị iche iche na-enweghị nchegbu gbasara mmebi pH metụtara.
7. Ndakọrịta: HEC dakọtara na ọtụtụ ihe ndị ọzọ dị iche iche, gụnyere nnu, acids, na organic solvents. Nkwekọrịta a na-enye ohere ịmepụta usoro mgbagwoju anya nwere njirimara ahaziri na ụlọ ọrụ dịka ọgwụ, nlekọta onwe onye, ​​na ihe owuwu.
8. Biodegradability: A na-enweta HEC site na isi mmalite dị ka osisi pulp na owu, na-eme ka ọ bụrụ ihe na-emebi emebi na gburugburu ebe obibi. A na-ahọrọkarị ya karịa polymers sịntetik na ngwa ebe nkwado dị mkpa.

Njirimara anụ ahụ nke hydroxyethyl cellulose (HEC) na-eme ka ọ bụrụ ihe mgbakwunye bara uru na ụlọ ọrụ dị iche iche, ebe ọ na-enye aka na arụmọrụ, nkwụsi ike, na ịrụ ọrụ nke ngwaahịa na nhazi dị iche iche.
