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 bentonite clay?
A natural aluminum phyllosilicate clay (mostly montmorillonite); as food additive E558 it’s used to prevent clumping (anti‑caking) and to clarify wine and juices as a fining/processing aid.
How much bentonite clay to drink for detox?
There is no approved or evidence‑based oral “detox” dose—health authorities do not recommend drinking bentonite clay, which can bind medications/nutrients and may contain heavy metals.
Does bentonite clay expire?
Being a mineral, it doesn’t spoil, but follow the manufacturer’s shelf life; store airtight and dry to avoid moisture, contamination, or caking.
How to use bentonite clay?
In foods it’s added by manufacturers as a small‑dose anti‑caking agent, or hydrated as a slurry to fine wine/juice and then removed with the sediment; it’s not intended to be taken as a drink.
Is bentonite clay safe?
At permitted food levels E558 is considered safe (e.g., GRAS in the U.S.; EFSA found no concern at reported uses), but ingesting clay products for “detox” is not advised due to possible contaminants and interactions; avoid inhaling the dust.
