Popular questions
How to remove calcium silicate from pool?
Calcium silicate scale is very hard and relatively acid‑resistant, so it’s typically removed by mechanical means (pumice/scale pads or bead blasting) after lowering pH and using a sequestering agent; an acid spot test that doesn’t fizz helps confirm it’s silicate, not carbonate. Prevent recurrence by keeping water balanced (pH/alkalinity/calcium) and using a sequestrant.
What is calcium silicate board?
A rigid, noncombustible building/insulation board made from calcium silicate hydrates, valued for fire resistance, moisture tolerance, and dimensional stability. It’s used for fireproofing, lining stoves/flues, and thermal or acoustic insulation.
How to cut calcium silicate board?
Score‑and‑snap works for thin sheets; thicker boards are cut with a circular saw using a carbide or diamond blade at a slow feed rate. Control dust with wet cutting or HEPA extraction and wear PPE (respirator, eye protection, gloves).
Is calcium silicate bad for you?
As a food additive (E552) used mainly as an anticaking agent, it’s considered safe at permitted levels (JECFA ADI “not specified”; FDA GRAS). The main concern is inhaling fine dust in occupational settings, which can irritate the respiratory tract.
Is calcium silicate vegan?
Yes—it's a mineral/synthetic ingredient with no animal-derived components, so E552 is generally suitable for vegans.
What is magnesium aluminum silicate?
A refined clay mineral of magnesium, aluminum and silicate layers used mainly as a thickener/stabilizer and anti‑caking agent, similar in function to the magnesium silicates covered by E553 (e.g., talc/magnesium silicate).
Is magnesium aluminum silicate safe?
Yes—when of food/cosmetic grade and used as authorized, it’s considered safe; it is insoluble, minimally absorbed, and specifications require it to be asbestos‑free and low in heavy metals.
Does magnesium aluminum silicate cause cancer?
There’s no evidence it causes cancer when asbestos‑free and used as intended; cancer concerns mainly involve inhalation of asbestos‑contaminated talc, not food/cosmetic‑grade materials.
Is magnesium aluminum silicate safe for skin?
Yes—cosmetic safety reviews consider it safe as used; it largely sits on the skin with minimal absorption, though avoiding inhalation of powders is advisable.
Is magnesium silicate harmful?
Food‑grade magnesium silicate (E553) is generally considered safe at permitted levels and is poorly absorbed; the main risks relate to inhaling fine talc dust or using non‑food‑grade/asbestos‑contaminated material.
