Keyway Industrial Limited Colloidal silica What is Colloidal Silica/ Silica Sol? Colloidal silica is a dispersion of amorphous silicon dioxide (silica) particles in water. These amorphous silica particles are produced by polymerizing silica nuclei from silicate solutions under alkaline conditions to form nanometer sized silica sols with high surface area. A charge is then induced on the silica nanoparticle surface that allows the silica particles to repel one another and form a stable dispersion, or colloid. Colloidal Silica Characters: Colloidal silicas are produced in a variety of grades that range in a number of factors. Particle size typically varies from 5nm to 40nm, and particle size distribution can vary from narrow to wide depending on the manufacturing process. Standard colloidal silica is stable at a pH from 8 - 10.5 and carries an anionic surface charge that is stabilized with sodium or ammonium. In certain grades, some of the silicon atoms in the silica particle are replaced with aluminate ions to allow for enhanced stability in a wider pH range, usually 3.5 - 10.5. Colloidal Silica Application: Densification of concrete, cement, and other materials. Fine retention in paper manufacturing. Enhanced bonding of waterborne adhesives. Improved surface friction and anti-slip properties. Wastewater filtration flocculant. Investment casting binding. Anti-soilant textile coatings.

Introduction Silica Absorbent Granule particles have a multi microporous structure. Silica Absorbent Granule has strong adsorption capacity for leaked pollutant liquids such as diesel, gasoline, engine oil, No. 2 flotation oil, toluene, xylene, kerosene, nitrobenzene, formaldehyde, methanol and ethanol. Silica Absorbent Granule can adsorb pollutant liquid equivalent to 6 times its weight (about 5-6 kg of oil and chemical liquid can be adsorbed per kg of Silica Absorbent Granule). Silica Absorbent Granule provides a low-cost and environment-friendly cleaning scheme for emergency liquid absorption treatment of oil leakage pollution on land and at sea. Characteristic Silica Absorbent Granule has hydrophilicity, lipophilicity, high liquid absorption rate, fast liquid absorption rate and good oil-water selectivity. Silica Absorbent Granule is easy to transport and store, and can float on the water before and after liquid absorption, with high oil retention rate. Silica Absorbent Granule has large adsorption capacity, good oil retention, high adsorption efficiency and reduced treatment time. Silica Absorbent Granule can reduce the consumption in the oil cleaning process by 80% and has low cost. Application Silica Absorbent Granule is suitable for cleaning the oil slick on the surface of reservoirs, lakes, sea surfaces and sewage tanks of sewage treatment plants. Silica Absorbent Granule plays a great role in adsorbing oil leakage of plant workshop equipment, leakage of liquid storage tank, cleaning of cabin, wharf equipment, cabin oil, diesel leakage or chemical dangerous liquid.
