What is colloidal silica good for?
Colloidal silica is used in a broad range of industries and applications, including: Densification of concrete, cement, and other materials. Fine retention in paper manufacturing. Enhanced bonding of waterborne adhesives.
What is colloidal silica gel?
SPE Production & Operations. Summary. A practical reservoir fluid-flow control system based on colloidal silicagel was developed. Colloidal silica gel is an environmentally benign systemthat provides easy surface handling, reliable gel-time control at temperaturesup to 250 degrees F, and high in-situ performance.
What is sol-gel and colloid?
Sol–gel is a wet-chemical process that involves the formation of an inorganic colloidal suspension (sol) and gelation of the sol in a continuous liquid phase (gel) to form a three-dimensional network structure.
What is sol-gel silica?
The sol-gel process is widely used to produce pure silica particles due to its ability to control the particle size, size distribution and morphology through systematic monitoring of reaction parameters.
What are the side effects of silica?
Breathing in very small (“respirable”) crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease.
How do you make silica sol?
The silica sol, which size is about 10 nm, could be prepared by heating the mixed solution of sodium silicate and silicate solution removed sodium ions at pH 10 and 80. And the silica sol grew into about 50 nm as silicate solution was added to silica sol solution.
What is the difference between sol and colloid?
Colloid is a mixture in which one substance is dispersed in another substance. It has dispersed medium and dispersed phase. Sol is a type of colloid in which the dispersed phase is solid and dispersed medium is liquid. It is the liquid state of a colloidal solution.
How does a sol differ from a gel?
A sol is a liquid. The continuous phase in a sol is a liquid and the dispersed phase is a solid. A gel is a wet solid-like material in which a solid network of interconnected nanostructures spans the volume of a liquid medium. The continuous phase is a solid network and the dispersed phase is a liquid.
Is colloidal silica safe?
Colloidal silica is not classified as harmful, but as mildly irritating. Because the products can have a drying effect on the skin, protective gloves should always be used. In case of skin contact, wash the area of contact with plenty of water. The use of safety glasses is always recommended.
Is silica bad for your kidneys?
Silica dust particles are tiny, over 100 times smaller than the sand you see on the beaches. If you are exposed to silica dust in the workplace, this can cause many chronic health problems including kidney damage and kidney failure. The more you are exposed, the greater the risk.
What is the chemical formula for silica?
The formula of the chemical compound Silicon dioxide is SiO2
What is colloidal silicon dioxide?
Colloidal silicon dioxide is actually a commonly used filler product. Also known as colloidal silica, this agent finds itself into many food and medicine products. In addition, its uses aren’t just limited to food and medicine. Since silicon is so abundant and versatile, manufacturers in other industries also find many uses for it.
What is liquid silica supplement?
Liquid silica is a health supplement that supports the connective tissues in your body. Liquid silica facilitates the construction of connective tissues both on the inside and the outside of these tissues.
What is silica concentrate?
Eidon Ionic Minerals Silica Liquid Concentrate is a unique formula that helps promote lustrous hair, supple skin and strong nails. Silica is essential for the proper utilization of calcium and for maintaining healthy connective tissue – a key component of cardiovascular, gastrointestinal, joint and bone health.
