Sodium lignosulfonate is used in the food industry as a foaming agent, for the production of paper and glue, as well as other elements that come into contact with food. It has antimicrobial properties. It is used as a preservative, as a mineral powder, as an ingredient in animal feed and ceramics. It is used in the construction, chemical, textile (leather), metallurgical, oil industries. Also in the production of fire retardant materials, in rubber vulcanization and in organic polymerization.
Lignosulfonate is an irreplaceable component in the production of cement, concrete and gypsum. When a substance is added to the mass, its fluidity and rheological properties increase. The mechanical strength of the finished product also increases because the setting time of cement and gypsum is slowed down. This has a positive effect on the durability and wear resistance of the hardened mixtures.
In the production of emulsions, lignosulfonate also finds a worthy application. With the help of a specific substance, water-oil emulsions are stabilized. The positive impact is not limited to this, because:
- Increased resistance to mechanical factors;
- Reduced susceptibility to salt pollution and changes in temperature indicators;
- Dispersion of micelles is ensured.
Sodium lignosulfonate plays an important role in the manufacture of ceramic products. It is used as a binder. For ceramic products to serve for a long time, you need high-quality raw materials. With the use of sodium lignosulphonate Malaysia, remarkable results are achieved. LST increase the mechanical strength of the raw material at the initial stage of production. It also reduces the water content in the mixture and eliminates the risk of solid sludge. This has a beneficial effect on the quality of the finished ceramic products.
The chipboard industry is another area in which lignosulfonates are widely used. Such substances are ideally suited as a hardening additive. They have high binding and adhesive properties. When using LST in the production of boards, the resin content is reduced and the adhesion of wood particles is improved. The toxicity of chipboard is significantly reduced, since the emission of formaldehyde, which is harmful to health, is reduced by 50%.
In the manufacture of adhesives and resins, lignosulfonates complement or replace synthetic products. They form a chemical bond with the resin and improve the performance of the final products. In the glue, the formaldehyde content is significantly reduced. Therefore, when using the product, the negative impact on health and nature is reduced. For more articles like this one, click here.
