Refining
Refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one.
AntiscaLANT
Rishscale
Polyacrylamide Cationic Series (CPAM)
RISHSCALE offers a range of products with low to High molecular weight antiscalants. These are used to optimize the anti-scale performance through the following mechanisms: – Solubility enhancement by threshold effect – Crystal modification – Dispersing activity
Defoamers
RiShfoam
Defoamers
RISHFOAM defoamers prevent generation of foams and causes existing foams to rapidly collapse. RISHFOAM series of defoamers are either Silicon based, non-silicones based or Fatty acid based. Silicones’ low surface tension and interfacial properties, combined with their lack of foam-stabilization properties cause the foam wall to thin and collapse. Fatty acid based defoamers are a composition of a polyether surfactant and a polyhydric alcohol fatty acid ester. RISHFOAM defoamers with different solid content can be used in a wide range of industries.
