Are Lignosulfonates safe?
As regards the safety for the target species, the maximum recommended content of lignosulphonate of 10,000 mg/kg complete feed is considered safe in weaned piglet. A safe concentration of lignosulphonate in feed for salmonids and dairy cows could not be identified.
What is magnesium lignosulfonate?
Magnesium Lignosulfonate is by product of paper industry from sulfite pulping process,in brown powder form,by nature is anionic polyelectrolyte polymers. Can be used as water reducer,dispersant of pesticide and viscosity depressant,Binder of powdery and granular materials,Dust supressant and so on.
How is sodium lignosulfonate made?
With pulp mill waste as a raw material,Sulfite or bisulfate process. Bisulfite pulping of calcium contained in the pulp waste directly binding to lignin hydroxyl molecules generated lignin. Then added to the filtrate Na2CO3, turn into calcium lignin sulfonate sodium. The reaction temperature is preferably 90 deg.]
What is modified lignosulfonate?
Lignosulfonates are obtained from sulfite pulping processes wherein cellulose is extracted from wood in the pulp industry. Another application is as a starting material in the production of chemically modified lignosulfonate, which is used in oil well drilling fluids and dispersion of pigments.
What is lignosulfonate used for?
Lignosulfonates are used to disperse pesticides, dyes, carbon black, and other insoluble solids and liquids into water. They are used in tanning leather. They are also used to suppress dust on unpaved roads. Oxidation of lignosulfonates from softwood trees produced vanillin (artificial vanilla flavor).
Is lignosulfonate soluble in water?
Physicochemical Properties of Lignosulfonates In contrast to other technical lignin, lignosulfonate possesses good water solubility due to an abundance of sulfonate groups [111].
Is sodium lignosulfonate hazardous?
Not classified as a hazardous substance or mixture according to OSHA Hazard Communication Standard 1910.1200.
What is calcium lignosulfonate used for?
The intended use of calcium lignosulfonate (40-65) is as a carrier (encapsulating agent) for fat-soluble vitamins, carotenoids, and other functional ingredients in, e.g., fruit- based beverages,vitamin drinks, dairy products, and hard candies.
What is calcium Lignosulphonate?
Calcium lignosulfonate (40-65) is an amorphous material derived from lignin. It is a light-yellow-brown powder that is soluble in water, but practically insoluble in organic solvents.
How is lignosulfonate used as a dispersing agent?
Lignosulfonate is also used as a dispersing agent in materials, such as in the production of brick or tile. Another application is as a starting material in the production of chemically modified lignosulfonate, which is used in oil well drilling fluids and dispersion of pigments.
What are the uses of lignosulfonates in leather?
Lignosulfonates are used to disperse pesticides, dyes, carbon black, and other insoluble solids and liquids into water. They are used in tanning leather. They are also used to suppress dust on unpaved roads. Oxidation of lignosulfonates from softwood trees produced vanillin (artificial vanilla flavor).
How is lignosulfonate used in oil well cementing?
Another application is as a starting material in the production of chemically modified lignosulfonate, which is used in oil well drilling fluids and dispersion of pigments. Lignosulfonate is also the most common set retarder for oil well cementing [5].
How does lignosulfonate dust control soil stabilization treatment?
Lignosulfonate works by binding the road surface particles together. Water evaporates from the lignin as it dries, and the dust particles are trapped by the high-viscosity, naturally sticky material. In addition, over time the lignin becomes completely insoluble due to solar heating.
