Plasterboard

Gypsum board is very accommodating for the constructors and designers as it helps them in all construction-related matters.

Sodium lignosulfonate

This is often used for the production of paper and in adhesives for articles that come into contact with food. It has preservative properties and is used as an ingredient in animal feed.  According to the past experiences, this can be used for textile and chemical industry and construction industry. Sodium lignosulfonate for ceramic industries has many uses, such as it can absorb and disperse cement geology, water reducer, oil field, wall consolidation, and clogging agent for oil exploration. filler dispersant dyes, dispersing agents, acid dye thinners can be used for refractory materials, disperse ceramics, adhesives, water reduction enhancers, 70% -90% performance enhancement, etc.

Production of building materials: due to their astringent, adhesive, and surfactant properties, lignosulfonates are used for the production of sheets: wood chips, wood fiber, and mineral cotton. Since this production uses rather deficient, expensive, toxic soil, phenol-formaldehyde, carbamide-phenol-formaldehyde, a mixture of modified lignosulfonate (20-30%) and soil, it allows to obtain a combined binder, therefore the toxicity of the slabs, worked with Additives based on lignosulfonates, it is reduced by up to 50%. If 40 kg / m2 of lignosulfonate is used during the production of mineral cotton sheets, a reduction in the flow volume of toxic phenolic alcohols can be achieved and thus a significant reduction in harmful emissions to the atmosphere. In addition, the products are more solid and waterproof.

Concrete industry: the use of sodium lignosulfonates, related to hydrophilic plasticizers, in the production of concrete and dry construction mixtures, allows reducing the consumption of components by up to 10-15%. The mixing of the concrete mass is reduced and its strength increases, the rate of hardening slows down. In addition to lignosulfonates in an amount of 0.15-0.20%, it is necessary to enter superplasticizers from the mass of dry matter in an amount of 0.5-2.0% of the mass of dry concrete. By replacing superplasticizers with lignosulfonates, the strength of concrete increases by up to 20-25%, frost resistance – by 3-4 times, and the cost of mixtures reduce the cause of adding small amounts of lignosulfonates, which it is connected with its adsorption on the surface of a hard phase. The use of lignosulfonates reduces the humidity of the raw sludge while maintaining its flow behavior, which increases the production of the stove and reduces the specific flow volume for the combustion of the clinker. With the use of lignosulfonate based enhancers, the production of crushing units increases, and there is the possibility of changing expensive and substandard chemicals.
