SAFETY CERTIFICATE OF THE SUBSTANCE

Name and composition of the substance or material

Name of the substance: Powdered technical lignosulfonates

Synonyms: Powdered concentrates of sulfite yeast mash

Lignosulfonates are mede from: Lignin in the process of bisulfite cooking of wood with sodium base, sodium-magnesium base acid (in production of cellulose)

Product is obtained: In the process of concentration of bisulfite alkali liquor by evaporatian up to 18-30% dry substance and posterior drying of this substance in a spray drier up t6 92-96% dry substance.

Structural formula Composition (component ingredients) % Class of danger Sodium lignosulfonate (sodium­magnesium lignosulfonate) (basic Material) 66-71 4(1,2) ; 3 (3) Sugar (glucose) 12-10 4 (1) Sodium salts of sulphur acid (sodium bisulfite) 12-14 3 (1) Health effect Low-hazard (Iow-toxic) substance. 4th class of danger according to State Standard 12.1.007 (1,2) Limit of concentration (active area) 6,0 mg/m2, Lignin(s) (1,2.3)

Current specs apply to Powdered Technical Lignosulfonates. These are sodium, sodium-ammonium, sodium-magnesium and magnesium salts of lignin sulfonic acids with the admixture of reducers and mineral substances. They are intended for the use as follows.

* For production of pesticides and seed protectants in chemical industry. * In well-boring as a component for drilling fluid production * In cement industry as a plasticizer of cement and for dilution of rough sludge * In foundry as a binder for agglutinant sands and core sand mixtures * In production of non-ferrous metals as a flotation reagent, and as a binder in the process of briquetting of fine-grained raw materials * In production of fireproof materials (bricks, etc.) for quality improvement * As a binder in the process of fine-grained coal briquetting. Crash-proof briquettes are obtained. They are used in exchange for expensive coke * As a bonding component in production of flake boards and fiberboard * As a component in skin (hide) tanning * In production of concrete for quality improvement and concrate savings
