Problems solved by technology

However, the addition of surfactants also has some negative issues
One is that the concentration of surfactants often directly affects the final shape of the product, and the concentration of surfactants needs to be precisely regulated in the preparation process, which brings a lot of trouble to industrial production; the other is that surfactants are easily adsorbed on the product. The surface of the product brings inconvenience to the cleaning of the product, thus affecting the purity of the final product
