Physical and Chemical Properties | The chemical product is a light yellow colloid. |
first add water to the reaction kettle, then add formaldehyde solution, slowly add CMC under stirring, stir for 1 h after adding, then add crosslinking agent complex salt and demulsifier, and place for 1 h to form jelly. Finally, cellulase is added for hydration, and the product is gradually unstuck and hydrated after 10 h.
Feeding ratio: water: formaldehyde: CMC: complex salt: demulsifier: cellulase = 1: 2.5: 3.5: 1.4: 0.1: 0.0045.
