Application

1.Wen-lun gum is a kind of soluble exopolysaccharide produced by Alcaligenessp through aerobic deep fermentation. Because of its good thickening and anti-segregation properties, it has been used as a good stabilizer and thickener in the field of cement mortar, concrete and other building materials.

2.It has good temperature resistance, its aqueous solution has good viscosity and rheological properties, can be resistant to high concentration of calcium ions, used in the cement industry can be used as cement admixture, increase the consistency and rheological properties of ore, improve the stability of concrete self-compaction, increase the mud concrete pressure resistance to secrete water.

3.Used in polymer, oilfield applications, casting coatings, pigment suspensions, cement or concrete thickeners, tire sealants and coating thickeners.
