Sodium Metasilicate reacts with acids to produce silica gel. [6] Cements and Binders - dehydrated sodium metasilicate forms cement or binding agent. Pulp and Par - sizing agent and buffer/stabilizing agent when mixed with hydrogen peroxide. Soaps and Detergents - as an emulsifying and suspension agent.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Colloidal silica gel with light opalescence. Silica gel is an amorphous and porous form of silicon dioxide (silica), consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or vacuum.
In acidic solutions, the silicate ions react with hydrogen ions to form silicic acids, which tend to decompose into hydrated silicon dioxide gel. [citation needed] Heated to drive off the water, the result is a hard translucent substance called silica gel, widely used as a desiccant. It can withstand temperatures up to 1100 °C. [citation needed]
Silicic acids can be seen as hydrated forms of silica, namely 2 H 2x SiO x+2 = SiO 2 ·(H 2 O) x. Indeed, in concentrated solutions, silicic acids generally polymerize and condense, and ultimately degrade to silicon dioxide and water. The intermediate stages may be very thick liquids or gel-like solids.
Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.
A basic gel fragrance air freshener An automatic air freshener. Mechanisms for the control of indoor airborne odors can be grouped into various different classes: Masking: a pleasant odor may be used to overwhelm unwanted odors. Adsorption: adsorbents like zeolite, activated charcoal, [11] or silica gel may be used to capture odor-producing ...
Polymethylsiloxane polyhydrate (PMSPH), or methylsilicic acid hydrogel (brand name — Enterosgel), is an enterosorbent [1] used for binding and removing various toxic substances, infectious agents and metabolites from the gastrointestinal tract.
