Cellulose ethers na ojiji ha
Cellulose ethers bụ ezinụlọ nke polymers soluble mmiri nke sitere na cellulose, bụ isi ihe nhazi nke mgbidi cell osisi. A na-emepụta ihe ndị a site na mgbanwe kemịkalụ nke cellulose, na-ewebata otu ether dị iche iche iji kwalite njirimara ha na-arụ ọrụ. Ethers cellulose a na-ahụkarị gụnyere Hydroxypropyl Methylcellulose (HPMC), Carboxymethyl Cellulose (CMC), Hydroxyethyl Cellulose (HEC),Methyl cellulose(MC), na Ethyl Cellulose (EC). Nke a bụ ụfọdụ isi ihe eji eme ihe n'ofe ụlọ ọrụ dị iche iche:
1. Ụlọ ọrụ ihe owuwu:
- HPMC (Hydroxypropyl Methylcellulose):
- Adhesives Taịlị:Na-eme ka njide mmiri dịkwuo mma, ịrụ ọrụ, na nrapado.
- Mortars na ihe atụ:Na-akwalite njide mmiri, ịrụ ọrụ, ma na-enye oge oghere ka mma.
- HEC (Hydroxyethyl cellulose):
- Agba na mkpuchi:Na-arụ ọrụ dị ka onye na-agba agba, na-enye njikwa viscosity na nhazi mmiri.
- Methyl cellulose (MC):
- Mortars na plasta:Na-akwalite njide mmiri na ịrụ ọrụ na ngwa ndị dabeere na ciment.
2. Ngwa ọgwụ:
- HPMC na MC:
- Ụdị mbadamba nkume:A na-eji ya dị ka ihe nchikota, ndị na-ekesa, na ihe ntọhapụ na-achịkwa na mbadamba ọgwụ.
3. Ụlọ ọrụ nri:
- Carboxymethyl cellulose (CMC):
- Thicker na Stabilizer:Ejiri ya na ngwaahịa nri dị iche iche iji nye viscosity, melite udidi, na ịkwado emulsions.
4. Mkpuchi na agba:
- HEC:
- Agba na mkpuchi:Na-arụ ọrụ dị ka onye na-agbapụta, stabilizer, ma na-enye ihe ndị na-asọpụta ka mma.
- Ethyl cellulose (EC):
- Mkpuchi:Eji maka imepụta ihe nkiri na mkpuchi ọgwụ na ịchọ mma.
5. Ngwaahịa nlekọta onwe onye:
- HEC na HPMC:
- Shampoos na lotions:Mee dị ka ndị na-agba agba na ndị na-eme ka ahụ sie ike na usoro nlekọta onwe onye.
6. Nrapado:
- CMC na HEC:
- Adhesives dị iche iche:Melite viscosity, adhesion, na rheological Njirimara na nrapado formulations.
7. Akwa:
- CMC:
- Nha akwa:Na-arụ ọrụ dị ka onye na-ahụ maka nha, na-eme ka adhesion na mmepụta ihe nkiri na akwa akwa.
8. Ụlọ ọrụ mmanụ na gas:
- CMC:
- Mmiri mmiri mmiri:Na-enye njikwa rheological, mbelata mfu mmiri, na mgbochi shale n'ime mmiri olulu mmiri.
9. Ụlọ ọrụ akwụkwọ:
- CMC:
- Mkpuchi na nha akwụkwọ:A na-eji emeziwanye ike akwụkwọ, mkpuchi mkpuchi, na nha.
10. Ngwa ndị ọzọ:
- MC:
- Ihe nchacha:A na-eji ya eme ihe na-eme ka ọ sie ike na nkwụsi ike n'ụdị ụfọdụ ncha.
- EC:
- Ngwa ahịa ọgwụ:A na-eji ya n'ụdị ọgwụ ahapụpụtara.
Ngwa ndị a na-eme ka ọnụọgụ cellulose ethers dị iche iche pụta ìhè na ụlọ ọrụ dị iche iche. Eter cellulose a kapịrị ọnụ a na-ahọrọ na-adabere na ihe ndị a chọrọ maka ngwa ngwa, dị ka njide mmiri, nrapado, njupụta, na ike ịmepụta ihe nkiri. Ndị na-emepụta ihe na-enyekarị ọkwa dị iche iche na ụdị cellulose ethers iji gboo mkpa dị iche iche nke ụlọ ọrụ dị iche iche na nhazi.
