Kedu ihe bụ ọdịdị nke Hydroxyethyl Methyl Cellulose?

Hydroxyethyl Methyl Cellulose (HEMC) bụ cellulose ether ewepụtara, yiri Hydroxypropyl Methylcellulose (HPMC), nwere ihe pụrụ iche sitere na nhazi kemịkal ya.Nke a bụ nkọwa nke ọdịdị nke Hydroxyethyl Methyl Cellulose:

1. Ọdịdị kemịkalụ:

A na-emepụta HEMC site n'ịgbanwe cellulose site na mmeghachi omume kemịkal, kpọmkwem site na iwebata ma hydroxyethyl (-CH2CH2OH) na methyl (-CH3) otu n'ime ọkpụkpụ cellulose.Usoro kemịkalụ a na-enye HEMC njirimara ya na arụ ọrụ ya.

2. Ọdịdị Hydrophilic:

Dị ka cellulose ethers ndị ọzọ, HEMC bụ hydrophilic, nke pụtara na ọ nwere njikọ maka mmiri.Mgbe a gbasasịrị n'ime mmiri, ụmụ irighiri HEMC na-eme ka mmiri dị ọcha ma na-emepụta ngwọta viscous, na-enye aka n'ịba ụba na njide.Ụdị hydrophilic a na-enye ohere ka HEMC na-amịkọrọ ma na-ejigide mmiri, na-eme ka arụmọrụ ya dị iche iche dị iche iche.

3. Solubility:

HEMC na-agbaze na mmiri, na-emepụta ngwọta doro anya, viscous.Ogo nke solubility na-adabere n'ihe ndị dị ka ịdị arọ molekụla, ogo nke nnọchi, na okpomọkụ.Ihe ngwọta HEMC nwere ike ịmalite nkewa nkewa ma ọ bụ gelation n'okpuru ọnọdụ ụfọdụ, nke enwere ike ịchịkwa site na ịhazi usoro nhazi.

4. Ngwongwo gbasara nka:

HEMC na-egosipụta omume pseudoplastic, nke pụtara viscosity ya na-ebelata n'okpuru nrụgide siri ike.Ngwongwo a na-enye ohere ka ihe ngwọta HEMC na-agba ọsọ ngwa ngwa n'oge ngwa mana ọ na-adaba n'elu ma ọ bụ na-ezu ike.Enwere ike ịhazi njirimara rheological nke HEMC site n'ịgbanwe ihe ndị dị ka itinye uche, ịdị arọ molecular, na ogo nke nnọchi.

5. Ime ihe nkiri:

HEMC nwere ihe na-emepụta ihe nkiri, na-enye ya ohere ịmepụta ihe nkiri na-agbanwe agbanwe na nke jikọrọ ọnụ mgbe ihicha.Ihe nkiri ndị a na-enye ihe mgbochi, adhesion, na nchebe na ihe ndị dị na ngwa dị iche iche.Ikike imepụta ihe nkiri nke HEMC na-enye aka n'iji ya eme ihe na mkpuchi, adhesives na usoro ndị ọzọ.

6. Thermal kwụsie ike:

HEMC na-egosipụta nkwụsi ike nke okpomọkụ dị mma, na-eguzogide okpomọkụ dị elu n'oge nhazi na nchekwa.Ọ naghị eweda ma ọ bụ tufuo njirimara arụrụ ya n'okpuru ọnọdụ nrụpụta ụdị.Nkwụsi ike a na-ekpo ọkụ na-enye ohere iji HEMC mee ihe na nhazi nke na-eme ka ikpo ọkụ ma ọ bụ usoro ọgwụgwọ.

7. ndakọrịta:

HEMC dakọtara na ọtụtụ ihe ndị ọzọ, gụnyere organic solvents, surfactants, na polymers.Enwere ike itinye ya n'ime usoro nwere ihe mgbakwunye dị iche iche na-enweghị nnukwu mmekọrịta.Ndakọrịta a na-enye ohere iji HEMC na ngwa dị iche iche gafee ụlọ ọrụ dị iche iche.

Mmechi:

Hydroxyethyl Methyl Cellulose (HEMC) bụ ether cellulose dị iche iche nwere ihe pụrụ iche nke na-eme ka ọ baa uru na ụlọ ọrụ dị iche iche.Ọdịdị ya hydrophilic, solubility, rheological properties, ikike imepụta ihe nkiri, nkwụsi ike nke okpomọkụ, na ndakọrịta na-enye aka na irè ya na ngwa ndị dị ka mkpuchi, adhesives, ihe owuwu, ngwaahịa nlekọta onwe onye, ​​​​na ọgwụ.Site n'ịghọta ọdịdị HEMC, ndị na-emepụta ihe nwere ike ịkwalite ojiji ya na nhazi iji nweta njirimara arụmọrụ achọrọ na arụ ọrụ ngwaahịa.
