What is calcium silicate pipe insulation?
Calcium silicate (CalSil) is used to insulate high-temperature pipes and equipment and for fire endurance applications. Today’s calcium silicate manufactured in North America is noted for its high compressive strength, corrosion-inhibiting properties, and high-temperature structural integrity.
Does calcium silicate insulation contain asbestos?
When first developed, calcium silicate insulation was typically reinforced with asbestos fibers. By the end of 1972, all North American manufacturers had switched the reinforcing fibers to glass fiber, plant fibers, cotton linters, or rayon. Today, all North-American-manufactured calcium silicate is asbestos-free.
Is calcium silicate harmful?
It is common that sometimes consumers have questions whether calcium silicate is bad for our health and what are the possible health risks. It is generally considered safe but some people may be allergic or sensitive to it.
What is calcium silicate used for?
Calcium silicate (Ca2SiO4), also known as calcium silicon oxide, is a product derived from limestone and diatomaceous earth, and is used in the pharmaceutical industry as an anticaking agent. Anti-caking agents absorb moisture and allow products to flow freely during the manufacturing process.
Is calcium silicate insulation safe?
Not a hazardous substance or mixture. Not a hazardous substance or mixture. Temporary mechanical abrasion (itching) of skin, eyes and respiratory tract may occur upon exposure to fibers or dust during handling of this product and cannot occur unless there is direct contact.
What is the common name for calcium silicate?
Calcium silicate is the chemical compound Ca2SiO4, also known as calcium orthosilicate and is sometimes formulated as 2CaO·SiO2. It is also referred to by the shortened trade name Cal-Sil or Calsil. It occurs naturally as the mineral larnite.
Does calcium silicate absorb water?
The mechanism of calcium silicate is by water absorption. It is reported to absorb water at 2.5 times its weight to pull moisture away from the host ingredient. Calcium silicate has high water affinity. It traps water and retains it internally.
Is calcium silicate toxic?
The Panel considered that calcium silicate, magnesium silicate and talc have a low acute oral toxicity.
Is calcium silicate flammable?
Calcium silicate is a noncombustible, white or cream- colored, free-flowing powder that is prepared commer- cially from lime and diatomaceous earth; many different calcium silicates occur in nature in mineral form (e.g., wollastonite, afwillite, grammite).
What are the details of calcium silicate pipe?
Calcium silicate pipe is based on silicon oxide, calcium oxide and reinforcing fibers as the main raw material, after mixing, heating, gel, molding, autoclave hardening, drying and other processes made of a new type of insulation materials.
Is calcium a light metal?
Calcium is a silver-white light metal. It oxidizes in moist air and the surface becomes coated with calcium oxide, hyrdroxide and carbonate. Discovered in 1808, calcium makes up of about 3.4 % of the earth’s crust.
Is calcium ductile or malleable?
Calcium is a malleable, ductile, silver-white, relatively soft metal with face-centered, cubic crystalline structure. Chemically it resembles strontium and barium; it is classed with them as an alkaline-earth metalalkaline-earth metals, metals constituting Group 2 of the periodic table.
The calcium silicates have a number of uses in industry. Among the most important applications are their uses in building materials, such as some types of glass and cement (especially Portland cement), bricks and tiles for roofs, fireproof ceilings, and building boards.
