Nhazi na ọrụ nke cellulose ethers

A na-ekewa ethers cellulose dabere n'ụdị nnọchi kemịkalụ na ọkpụkpụ azụ cellulose. Ụdị cellulose ethers ndị a na-ahụkarị gụnyere methyl cellulose (MC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), carboxymethyl cellulose (CMC), na carboxyethyl cellulose (CEC). Ụdị ọ bụla nwere njirimara na ọrụ pụrụ iche. Nke a bụ ndakpọ nke nhazi na ọrụ ha:

1. Methyl cellulose (MC):
   • Ọrụ: A na-eji MC eme ihe n'ọtụtụ ebe dị ka onye na-agbapụta, stabilizer, na ihe nkedo na ngwa dị iche iche dị ka ọgwụ, ngwaahịa nri, na ihe owuwu. Ọ nwekwara ike rụọ ọrụ dị ka onye na-emepụta ihe nkiri na colloid na-echebe na sistemu colloidal.
2. Ethyl cellulose (EC):
   • Ọrụ: A na-eji EC eme ihe n'ụzọ bụ isi dị ka onye na-emepụta ihe nkiri na ihe mgbochi na mkpuchi ọgwụ, nkwakọ ngwaahịa nri, na ngwa mmepụta ihe ndị ọzọ ebe a chọrọ ihe nkiri na-eguzogide mmiri. A na-ejikwa ya dị ka ihe nkedo na ụdị usoro onunu ogwu siri ike.
3. Hydroxyethyl cellulose (HEC):
   • Ọrụ: A na-ejikarị HEC arụ ọrụ dị ka onye na-agba agba, rheology modifier, na onye na-ejigide mmiri n'ọtụtụ ngwa, gụnyere agba, mkpuchi, adhesives, ngwaahịa nlekọta onwe onye, ​​​​na mmiri na-egwupụta ihe. Ọ na-eme ka viscosity dịkwuo mma, udidi, na nkwụsi ike na nhazi.
4. Hydroxypropyl cellulose (HPC):
   • Ọrụ: HPC na-eje ozi dị ka onye na-emepụta ihe, ihe nkedo, na onye na-emepụta ihe nkiri na ọgwụ, ngwaahịa nlekọta onwe onye, ​​na ngwa nri. Ọ enhances viscosity, na-enye mmanu mmanu, na mma eruba Njirimara nke formulations.
5. Carboxymethyl cellulose (CMC):
   • Ọrụ: A na-eji CMC eme ihe n'ọtụtụ ebe dị ka onye na-ebu ibu, onye na-emezi ihe, na onye na-ejigide mmiri na ngwaahịa nri, ọgwụ ọgwụ, ngwaahịa nlekọta onwe onye, ​​na ngwa mmepụta ihe dị ka ncha na ceramik. Ọ na-enye viscosity, na-eme ka udidi dị mma, ma na-akwalite nkwụsi ike na nhazi.
6. Carboxyethyl cellulose (CEC):
   • Ọrụ: CEC na-ekerịta ọrụ ndị yiri ya na CMC ma jiri ya mee ihe dị ka onye na-ebu ibu, ihe nkwụsi ike, na onye na-ejide mmiri na ngwa dị iche iche, gụnyere ngwaahịa nri, ọgwụ na ngwaahịa nlekọta onwe onye. Ọ na-enye njikwa viscosity ma melite nkwụsi ike ngwaahịa.

cellulose ethers na-arụ ọrụ dị oke mkpa n'ọtụtụ ụlọ ọrụ na ngwa n'ihi ọrụ dị iche iche na njirimara ha. Ha na-enye aka na njikwa viscosity, ndozi ederede, nkwalite nkwụsi ike, yana imepụta ihe nkiri na usoro, na-eme ka ha bụrụ mgbakwunye bara uru n'ọtụtụ ngwaahịa na usoro.
