KARSHATI’S range of SOLUBLE OIL grades are used in manufacturing environment friendly products like light weight Autoclaved Aerated Concrete Blocks. ( AAC Block) Increasing awareness of Operating cost and % rejection of moulds has given us impetus to the development of different grades of soluble oils, as it plays very important role in controlling the rate of reactions between various ingredients like Aluminum Powder, lime , cement, silica from sand etc. To meet the growing demands of 21st century and ever evolving
construction industry, KARSHATI has developed a unique product called KVN -108 KVN-108 is a liquid admixture miscible in water and designed to suit the different quality of raw materials. During casting or green stage, controlling rate of reaction between various raw materials like Quick lime , aluminum powder and silica from Sand and cement etc is paramount to the stability of mould. KVN -108 acts as a catalyst as well as retarder. KVN- 108 contents a Plasticizer or a Super plasticizer either a non-surface active polymer or usually a blend of all to improve the bonding of particles and to prevent settling or clumping of light particles available in raw materials like sand, Aluminum Powder, quick Lime Etc. It also contains blend of some organic oils and surfactants and polymers to provide strength to cell walls at green stage inside the mass during reaction between solid mass, water and Metal Powder as well as liberation of Hydrogen gas by adjusting the surface tension of mass.Role of Soluble Oil plays a very important in prevention of mould shrinkage as it prevents the water separation from the solid mass and also plays important role in controlling the rate of reaction between various reactants like calcium (from cement & Lime) and Silica( From Cement & Sand ) which results in 1:1 nm Tobermorite( C- S-H Calcium Silicate Hydrate ) which is principal final product of AAC. Improper mixing of various ingredients in the formulation may results in un reactive Calcium Hydroxide which gives less than optimum block strength and also Lattice Shrinkage.
1) Reduction in Mould shrinkage related problems
2) Helps in Regulating rate of reaction between solid mass and metal Powder.
3) Reduction in Vertical , Horizontal and Rising cracks
4) Helps in forming Uniform cell structures by homogenizes entire cake mass
5) Provides strength to cells at green stage
6) Eco friendly product
7) Increased productivity
