Ụdị cellulose ether
Cellulose ethers bụ otu ụdị dị iche iche enwetara site na imezi cellulose eke ekemịkal, bụ isi akụkụ nke mgbidi cell osisi. Ụdị ether cellulose a kapịrị ọnụ na-ekpebi site na ọdịdị mgbanwe kemịkalụ ewebatara na ọkpụkpụ azụ cellulose. Nke a bụ ụfọdụ ụdị cellulose ethers a na-ahụkarị, nke ọ bụla nwere njirimara na ngwa ya pụrụ iche:
- Methyl cellulose (MC):
- Mgbanwe kemịkalụ: Mmalite nke otu methyl n'ime ọkpụkpụ azụ cellulose.
- Ngwongwo na ngwa:
- Mmiri-soluble.
- A na-eji ihe owuwu (mortars, adhesives), ngwaahịa nri, na ọgwụ (mkpuchi mbadamba).
- Hydroxyethyl cellulose (HEC):
- Mgbanwe kemịkalụ: Mmalite nke otu hydroxyethyl na ọkpụkpụ azụ cellulose.
- Ngwongwo na ngwa:
- Mmiri na-agbaze nke ukwuu.
- A na-ejikarị eme ihe ịchọ mma, ngwaahịa nlekọta onwe onye, agba, na ọgwụ.
- Hydroxypropyl Methyl Cellulose (HPMC):
- Mgbanwe kemịkalụ: Mmalite nke otu hydroxypropyl na methyl n'ime ọkpụkpụ azụ cellulose.
- Ngwongwo na ngwa:
- Mmiri-soluble.
- A na-eji ya eme ihe na ihe owuwu (ngwa ngwa, mkpuchi), ọgwụ na ngwaahịa nri.
- Carboxymethyl cellulose (CMC):
- Mgbanwe kemịkalụ: Mmalite nke otu carboxymethyl n'ime ọkpụkpụ azụ cellulose.
- Ngwongwo na ngwa:
- Mmiri-soluble.
- A na-eji ya dị ka ihe na-agbapụta agba na stabilizer na ngwaahịa nri, ọgwụ ọgwụ, textiles, na mmiri mkpọpu mmiri.
- Hydroxypropyl cellulose (HPC):
- Mgbanwe kemịkalụ: Mmalite nke otu hydroxypropyl na ọkpụkpụ azụ cellulose.
- Ngwongwo na ngwa:
- Mmiri-soluble.
- A na-ejikarị ọgwụ eme ihe dị ka ihe nchikota, onye na-emepụta ihe nkiri, na thickener.
- Ethyl cellulose (EC):
- Mgbanwe kemịkalụ: Mmalite nke otu ethyl na ọkpụkpụ azụ cellulose.
- Ngwongwo na ngwa:
- Mmiri na-adịghị edozi.
- Ejiri ya na mkpuchi, ihe nkiri, na usoro ntọhapụ ọgwụ na-achịkwa.
- Hydroxyethyl Methyl Cellulose (HEMC):
- Mgbanwe kemịkalụ: Mmalite nke otu hydroxyethyl na methyl n'ime ọkpụkpụ azụ cellulose.
- Ngwongwo na ngwa:
- Mmiri-soluble.
- A na-ejikarị arụ ụlọ (mortars, grouts), agba, na ihe ịchọ mma.
A na-ahọrọ ụdị ethers cellulose ndị a dabere na njirimara ha na ọrụ ha chọrọ maka ngwa dị iche iche. Mgbanwe nke kemịkalụ na-ekpebi ihe solubility, viscosity, na njirimara arụmọrụ ndị ọzọ nke cellulose ether ọ bụla, na-eme ka ha bụrụ ihe mgbakwunye dị iche iche na ụlọ ọrụ dị ka ihe owuwu, ọgwụ, nri, ihe ịchọ mma, na ndị ọzọ.
