Embodiment Construction
[0010] During implementation, the organic silicon functional chemical material in the present invention—sodium methyl silicate is synthesized by mixing cotton yarn bleaching waste liquid A and methyl silicate B in a weight ratio of A:B=4:1. The specific operation procedure is that after the cotton yarn bleaching waste liquid is settled in the sedimentation tank, it is poured into the reaction kettle according to the above formula as component A, and the methyl silicic acid of component B is added into the reaction kettle, stirred and mixed evenly, and heated to 90-95°C After 1-2h of heat preservation, precipitate and filter to obtain sodium methyl silicate.
[0011] Further introduce the implementation of the present invention below by embodiment:
[0012] 1. Take 800kg of cotton yarn bleaching waste liquid and put it into the reaction kettle, and gradually raise the temperature to 90°C.
[0013] 2. Take 200kg of methyl silicic acid and put it into the reaction kettle, stir e...
