Kedu ihe bụ Cellulose ether?

Cellulose ethers bụ ezinụlọ nke mmiri-soluble ma ọ bụ mmiri-dispersible polymers ewepụtara si cellulose, eke polymer dị na cell mgbidi osisi. A na-emepụta ihe ndị a site n'ịgbanwe usoro hydroxyl nke cellulose, na-ebute ụdị cellulose ether dị iche iche nwere ihe dị iche iche. Cellulose ethers na-achọta ọtụtụ ojiji n'ọtụtụ ọrụ dị iche iche n'ihi nchikota ha pụrụ iche nke ihe onwunwe, gụnyere mmiri solubility, ike na-akụda, ikike imepụta ihe nkiri, na nkwụsi ike.

Ụdị isi nke cellulose ethers gụnyere:

1. Methyl cellulose (MC):
   • A na-enweta Methyl cellulose site na iwebata otu methyl na otu hydroxyl nke cellulose. A na-ejikarị ya eme ihe dị ka ihe na-eme ka ihe na-esi ísì ụtọ na gelling na ngwa dị iche iche, gụnyere nri, ọgwụ na ihe owuwu.
2. Hydroxyethyl cellulose (HEC):
   • A na-emepụta Hydroxyethyl cellulose site na iwebata otu hydroxyethyl na cellulose. A na-eji ya eme ihe n'ọtụtụ ebe dị ka thickener, rheology modifier, na stabilizer na ngwaahịa dị ka ihe ịchọ mma, ihe nlekọta onwe onye, ​​na ọgwụ.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Hydroxypropyl methyl cellulose bụ cellulose ether emeziri ugboro abụọ, na-egosipụta ma hydroxypropyl na methyl otu. A na-eji ya eme ihe n'ihe owuwu ụlọ, ọgwụ, ngwaahịa nri, na ngwa ụlọ ọrụ dị iche iche maka ịgbatị ya, njide mmiri, na imepụta ihe nkiri.
4. Ethyl cellulose (EC):
   • Ethyl cellulose na-enweta site na iwebata otu ethyl na cellulose. A maara ya maka ọdịdị mmiri na-adịghị edozi ya ma na-ejikarị eme ihe dị ka onye na-emepụta ihe nkiri, karịsịa na ụlọ ọrụ ọgwụ na mkpuchi.
5. Carboxymethyl cellulose (CMC):
   • A na-enweta Carboxymethyl cellulose site na iwebata otu carboxymethyl na cellulose. A na-eji ya eme ihe n'ọtụtụ ebe dị ka ihe na-eme ka ọ dị arọ, onye na-eme ka ọ dị ike, na onye na-ejide mmiri na ngwaahịa nri, ọgwụ na ngwa ụlọ ọrụ mmepụta ihe.
6. Hydroxypropyl cellulose (HPC):
   • A na-emepụta hydroxypropyl cellulose site na iwebata otu hydroxypropyl na cellulose. A na-ejikarị ya na ụlọ ọrụ na-emepụta ọgwụ dị ka ihe nkedo, onye na-emepụta ihe nkiri, na thickener na nhazi mbadamba.

A na-eji cellulose ethers kpọrọ ihe maka ikike ha nwere imezi ihe ndị na-emepụta ihe na akụrụngwa nke usoro dị iche iche. Ngwa ha gbasara ụlọ ọrụ dị iche iche, gụnyere:

• Mwube: N'ime ngwa agha, ihe mkpuchi, na mkpuchi iji kwalite njide mmiri, ịrụ ọrụ, na ntinye.
• Ọgwụ: N'ime mkpuchi mbadamba nkume, ihe nchikota, na usoro mwepụta na-adịgide adịgide.
• Nri na ihe ọ drinksụ drinksụ: N'ime ihe ndị na-ekpu mmiri, ndị na-eme ka ahụ sie ike, na ndị na-anọchi abụba.
• Ihe ịchọ mma na nlekọta onwe onye: Na ude, lotions, shampoos, na ngwaahịa ndị ọzọ maka ihe na-eme ka ha sie ike ma na-eme ka ahụ sie ike.

Ụdị cellulose ether a kapịrị ọnụ a na-ahọrọ na-adabere na ihe ndị a chọrọ maka otu ngwa. Ntughari nke cellulose ethers na-eme ka ha baa uru na ngwaahịa dị iche iche, na-enye aka n'ịdị mma, nkwụsi ike, na ịrụ ọrụ.
