Cellulose ethers

Cellulose ethersbụ ezinụlọ nke mmiri-soluble polymers ewepụtara si cellulose, a eke polymer dị na cell mgbidi osisi. A na-emepụta ihe ndị a site na mgbanwe kemịkalụ nke cellulose, na-ebute ngwaahịa dị iche iche nwere ihe pụrụ iche. Cellulose ethers na-ahụta ojiji zuru ebe niile n'ofe ụlọ ọrụ dị iche iche n'ihi ike ha na arụ ọrụ pụrụ iche. Nke a bụ ụfọdụ ụdị cellulose ethers na ngwa ha:

1. Hydroxyethyl cellulose (HEC):
   • Ngwa:
     • Agba na mkpuchi: Na-arụ ọrụ dị ka onye na-agbapụta ihe na rheology modifier.
     • Ngwaahịa nlekọta onwe onye: Ejiri ya na shampoos, creams na lotions dị ka ihe na-eme ka ọ sie ike ma na-eme ka ahụ sie ike.
     • Ihe owuwu ihe: Na-eme ka njigide mmiri na-arụ ọrụ na ngwa ngwa na nrapado.
2. Hydroxypropyl Methylcellulose (HPMC):
   • Ngwa:
     • Ihe owuwu: A na-eji ngwa agha, nrapado, na mkpuchi maka ịrụ ọrụ na nrapanye ka mma.
     • Pharmaceuticals: Na-eje ozi dị ka ihe nkedo na ihe nkiri nke bụbu n'ụdị mbadamba.
     • Ngwaahịa nlekọta onwe onye: Ọ na-arụ ọrụ dị ka onye na-agba ume na nkwụsi ike.
3. Methyl Hydroxyethyl Cellulose (MHEC):
   • Ngwa:
     • Mwube: Na-eme ka njide mmiri na-eme ka mmiri sie ike ma na-arị elu n'ụdị ngwa agha.
     • Mkpuchi: Mma rheological Njirimara na agba na ndị ọzọ formulations.
4. Carboxymethyl cellulose (CMC):
   • Ngwa:
     • Ụlọ ọrụ nri: A na-eji ya dị ka ihe na-eme ka ọ sie ike ma na-eme ka ahụ sie ike na ngwaahịa nri dị iche iche.
     • Pharmaceuticals: Ọ ​​na-arụ ọrụ dị ka ihe nkedo n'ụdị mbadamba.
     • Ngwaahịa nlekọta onwe onye: Ọrụ dị ka thickener na stabilizer.
5. Ethyl cellulose (EC):
   • Ngwa:
     • Ọgwụ ọgwụ: Ejiri ya na mkpuchi maka usoro ntọhapụ a na-achịkwa.
     • Ihe mkpuchi na inks pụrụ iche: Ọ na-arụ ọrụ dị ka ihe nkiri mbụ.
6. Sodium Carboxymethyl Cellulose (NaCMC ma ọ bụ SCMC):
   • Ngwa:
     • Ụlọ ọrụ nri: A na-eji ya dị ka ihe na-agba ume na stabilizer na ngwaahịa nri.
     • Pharmaceuticals: Ọ ​​na-arụ ọrụ dị ka ihe nkedo n'ụdị mbadamba.
     • Ịgbapu mmanụ: A na-eji ya dị ka viscosifier na-egwupụta mmiri mmiri.
7. Hydroxypropylcellulose (HPC):
   • Ngwa:
     • Mkpuchi: Na-arụ ọrụ dị ka onye na-agbapụta ihe na ihe nkiri bụbu na mkpuchi na inks.
     • Ọgwụ: Ejiri ya dị ka ihe nchikota, nke na-agbasa, yana onye ntọhapụ na-achịkwa.
8. Microcrystalline cellulose (MCC):
   • Ngwa:
     • Ọgwụ: A na-eji ya dị ka ihe nchikota na nke na-agbasa n'ụdị mbadamba.

Ethers cellulose ndị a na-enye ọrụ dịgasị iche iche dị ka ịgbatị, njide mmiri, imepụta ihe nkiri, na nkwụsi ike, na-eme ka ha baa uru na ụlọ ọrụ dịka ihe owuwu, ọgwụ, nri, nlekọta onwe onye, ​​​​na ndị ọzọ. Ndị na-emepụta ihe na-emepụta cellulose ethers na ọkwa dị iche iche iji mezuo ihe achọrọ ngwa ngwa.
