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 yellow prussiate of soda in salt?
It’s sodium ferrocyanide (E535), an approved anti‑caking agent added in tiny amounts to keep table salt free‑flowing by preventing clumping.
What is yellow prussiate of soda made from?
It’s sodium ferrocyanide, the sodium salt of the [Fe(CN)6]4− complex, made industrially by combining iron salts with cyanide and sodium under controlled conditions to form a stable coordination compound.
Anticaking effect of yellow prussiate of soda (na4[fe(cn)6]10h2o)".\ how much is toxic?
It prevents salt crystals from sticking together by inhibiting crystal bridging and moisture‑induced clumping; the acceptable daily intake is 0–0.025 mg/kg body weight (≈1.75 mg/day for a 70‑kg adult), and permitted salt levels (typically about 10–20 mg/kg) keep exposures well below this.
E535 boots when opened?
If you mean opening a container of salt that contains E535, nothing special happens—it's stable and present at trace levels; just store salt dry and away from strong acids.
E535 or yellow prussiate of soda (yps) as a non-caking agent in salt…what is it?? all?
It’s sodium ferrocyanide (E535), a stable, approved anti‑caking agent used in minute amounts in table salt to keep it free‑flowing; safety assessments set an ADI of 0–0.025 mg/kg body weight, and regulatory limits in salt are typically around 10–20 mg/kg.
