Cellulose ethers na mpụta mgbidi mkpuchi:
2.1.Nkọwa nke cellulose ethers:
Cellulose ethers gụnyere methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), carboxymethylcellulose (CMC), wdg, nke a na-ejikarị na ngwa n'èzí n'ihi na ha pụrụ iche Njirimara.Na mgbidi agba.Ndị polymers ndị a na-arụ ọrụ dị ka ndị na-agba agba, ndị na-ekekọta, na rheology modifiers, na-enye mkpuchi ihe onwunwe ha dị mkpa.
2.2.Njirimara ndị siri ike:
Cellulose ethers bụ ndị na-emepụta ihe na-arụ ọrụ nke ọma nke na-eme ka viscosity nke mkpuchi dị elu, na-akwalite ngwa ka mma na ibelata sagging.Usoro ihe omimi nke cellulose ethers bụ mmiri na-ejide mmiri, na-eme ka viscosity kacha mma na ntinye ngwa ngwa.
2.3.Mgbanwe nke usoro ọmụmụ:

Mmekọrịta dị n'etiti cellulose ethers na ihe mgbakwunye:
Nchikota nke cellulose ethers na ihe mgbakwunye na eserese dị n'èzí na-emepụtakarị mmetụta synergistic nke na-eme ka arụmọrụ zuru ezu.Ọdịdị thixotropic nke cellulose ethers na-emeju ihe na-agbasasị na nkwụsi ike nke ụfọdụ ihe mgbakwunye, na-emezi ngwa ngwa na nhazi ihe nkiri.
Ọmụmụ ikpe na ihe atụ:
