Nhazi na Ọrụ nke Cellulose Ethers

A na-ekewa ethers cellulose dabere na ụdị nnọchi kemịkalụ dị na azụ cellulose. Ụdị ethers cellulose kachasị ewu ewu 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. Lee nkọwa nke nhazi na ọrụ ha:

1. Methyl Cellulose (MC):
   • Ọrụ: A na-ejikarị MC eme ihe dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka ihe sie ike, na ihe na-ejikọ ihe n'ọtụtụ ọrụ dịka ọgwụ, ihe oriri, na ihe owuwu. Ọ nwekwara ike ịrụ ọrụ dị ka ihe na-emepụta fim na ihe na-echebe colloid na sistemu colloid.
2. Ethyl Cellulose (EC):
   • Ọrụ: A na-ejikarị EC eme ihe dị ka ihe na-emepụta fim na ihe mgbochi n'ime mkpuchi ọgwụ, nkwakọ ngwaahịa nri, na ngwa ụlọ ọrụ ndị ọzọ ebe achọrọ ihe nkiri na-eguzogide mmiri. A na-ejikwa ya dị ka ihe na-ejikọ ihe n'ụdị ọgwụ siri ike.
3. Selulose Hydroxyethyl (HEC):
   • Ọrụ: A na-ejikarị HEC eme ihe dị ka ihe na-eme ka ihe dị arọ, ihe na-agbanwe ọdịdị ala, na ihe na-ejide mmiri n'ọtụtụ ụzọ, gụnyere agba, ihe mkpuchi, ihe na-eme ka ihe na-eme ka ihe dị nro, na ihe na-eme ka mmiri dị n'ime ya. Ọ na-eme ka ọ dịkwuo mma, na-eme ka ọ dị nro, na-eme ka ọ kwụsie ike, ma na-eme ka ọ kwụsie ike.
4. Selulose Hydroxypropyl (HPC):
   • Ọrụ: HPC na-arụ ọrụ dị ka ihe na-eme ka ihe sie ike, ihe na-ejikọ, na ihe na-emepụta ihe nkiri na ọgwụ, ngwaahịa nlekọta onwe onye, ​​na ngwa nri. Ọ na-eme ka viscosity dịkwuo mma, na-enye mmanụ ọkụ, ma na-eme ka ikike mmiri nke usoro ahụ ka mma.
5. Carboxymethyl cellulose (CMC):
   • Ọrụ: A na-eji CMC eme ihe nke ukwuu dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka mmiri sie ike, na ihe na-ejide mmiri n'ihe oriri, ọgwụ, ngwaahịa nlekọta onwe onye, ​​na ngwa ụlọ ọrụ dịka ncha na seramiiki. Ọ na-enye viscosity, na-eme ka udidi dị mma, ma na-eme ka usoro ahụ kwụsie ike.
6. Carboxyethyl Cellulose (CEC):
   • Ọrụ: CEC na CMC na-ekerịta ọrụ ndị yiri ya ma ejiri ya dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka mmiri sie ike, na ihe na-ejide mmiri n'ọtụtụ ọrụ, gụnyere ngwaahịa nri, ọgwụ, na ngwaahịa nlekọta onwe onye. Ọ na-enye njikwa viscosity ma na-eme ka ngwaahịa kwụsie ike.

Cellulose ethers na-arụ ọrụ dị oke mkpa n'ọtụtụ ụlọ ọrụ na ngwa dị iche iche n'ihi ọrụ na ihe onwunwe ha dị iche iche. Ha na-enye aka na njikwa viscosity, mmezi udidi, mmezi nkwụsi ike, na nhazi ihe nkiri na nhazi, na-eme ka ha bụrụ ihe mgbakwunye bara uru na ọtụtụ ngwaahịa na usoro.
