Quality Assurance & Testing Laboratory
Batch-to-batch consistency is the cornerstone of Rajaram Enterprise. Our state-of-the-art chemical analytical testing laboratory in Vapi tests every metric ton for Baume density, molar ratio, and clarity.
Zero Defect B2B Quality Control Systems
Our team of chemical engineers and QA specialists monitor the production parameters round-the-clock using ASTM, BIS, and international standard chemical testing protocols.
6-Stage Quality Testing Protocol
Raw Material Purity Verification
Strict screening of incoming dense soda ash and high-silica quartz sand. X-ray fluorescence and moisture testing ensure zero heavy metal contaminants before furnace loading.
Molar Ratio (Na₂O : SiO₂) Titration
High-precision acid-base titrimetric analysis with automated burettes to maintain exact silica-to-alkali ratios within strict ±0.05 molar tolerances.
Baume Gravity & Density Testing
Every liquid silicate batch is tested using calibrated Baume hydrometers and pycnometers at 20°C standard temperature to guarantee exact specific gravity (1.38 - 1.55).
Pressure Leaf Filtration (< 10 Micron)
Molten and liquid silicates pass through multi-stage high-pressure stainless leaf filters to strip all un-reacted quartz particles, yielding crystal-clear viscous liquid.
Viscosity & Stability Analysis
Rotational viscometer testing ensures consistent flow behavior for spray-drying detergent towers, paper corrugation adhesives, and foundry binder guns.
Final COA Generation & Dispatch Seal
A signed Certificate of Analysis (COA) with unique lot tracking numbers is issued for every tanker, carboy, drum, and export container before factory gate release.
Require Custom Ratio or Viscosity Testing?
We can formulate custom sodium silicate ratios, Baume densities, and solids percentages according to your exact industrial specifications.
