Ligin sulfonates salt from paper black liquor - all

This technology is used in paper making fiber materials will be the rest of all the ingredients into a chemical products, so as to make resources to make full use of the products, sodium xylose powder containing sodium lignin, of chitosan, they have very good dispersion, surface activity and adhesion, and may have to sex is widely used, this is accord with the trend of sustainable development, and its development prospect.

The main production steps

1, evaporation and concentration: the crowded syrup machine of extrusion black liquor pump into the black liquor of evaporation and concentration equipment for the system to reach the concentration, the requirements of the ingredients.

2, daqing heidimiao: will concentrate good black liquor pump into the pot, and join the daqing heidimiao quantitative proportion of the chemical composition, through chemical reaction has uniform product solution.

Three, to dry powder: the sulfonated reaction good solution pump into the special design of spray drying equipment, in the tower from liquid materials, high speed evaporation, dry into powder, and finally packaging.

Lignin main purpose of the products

Pulping black liquor as raw materials, with production ligin sulfonates salt powder, mainly in the concrete , adhesives, pesticides dispersant, asphalt emulsifier, oil well drilling agent use. In
