Introduction
Sodium lignosulfonate is a chemically modified product of natural lignin. It is yellow-brown powder with a slight aromatic smell and is non-toxic. Soluble in any hard water.
Preparation method
The acidic sulfite pulp wastewater from wood is precipitated by lime milk to convert and grade reducing sugars, and then filtered; After refining the filter cake, add acid to dissolve it, and then filter it. The filtrate is converted into sodium salt by sodium carbonate, evaporated, and dried by spray.
safety
This product is non-toxic and non flammable. During storage, it should be protected from rain and moisture. If there is clumping, it can be crushed or prepared into a solution for use, without affecting the effectiveness of use.
