Ịghọta CMC na Ọrụ Ya na Glaze Slurry
Carboxymethyl Cellulose (CMC) bụ polymer soluble mmiri nke ewepụtara na cellulose. A na-ejikarị ya na seramiiki glazes dị ka ihe nkedo na rheology modifier. CMC na-eme ka viscosity nke glaze dịkwuo mma, na-enyere aka ịnọgide na-enwe nkwusioru nke ụmụ irighiri ihe. Ọ na-emekwa ka nrapara nke glaze na elu seramiiki ma na-ebelata ntụpọ dị ka pinholes na crawling.
