Cellulose ethers

Cellulose ethersbụ ezinụlọ nke mmiri-soluble polymers ewepụtara na 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 thickener 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.
