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 oxide good for?
In foods, E530 is good for keeping powders free‑flowing (anti‑caking) and helping control acidity/alkalinity (pH); it may also serve as a source of magnesium in fortification.
What is magnesium oxide used for?
As a food additive it’s used in products like table salt, spices, cocoa, and drink or baking mixes to prevent clumping and to adjust pH; it can also supply magnesium in some fortified foods.
What is magnesium oxide 400 mg used for?
That tablet dose is a dietary supplement, not a food‑additive use; 400 mg MgO provides about 240 mg elemental magnesium and is used to address low magnesium or as an antacid/laxative, though it’s relatively poorly absorbed and can cause diarrhea at high doses.
Is magnesium oxide good for you?
At the small amounts used in foods, it’s considered safe (permitted in the EU as E530 and GRAS in the U.S.); as a supplement it can help correct deficiency but has lower bioavailability than some forms and high doses may upset the stomach or cause diarrhea.
What does magnesium oxide do?
In foods it prevents caking and helps stabilize pH, and can contribute magnesium for fortification.
