Fiberglass is harmful to humans.
Most of the fiberglass material is composed of silica, which is not toxic to the human body. But in the human body can not be decomposed, used to wipe the pot after a thorough rinse no problem, otherwise silica residue into the human body easy to get appendix.
The main components of glass fiber for silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the amount of alkali content in the glass can be divided into non-alkali glass fibers (sodium oxide 0% to 2%, is an aluminum borosilicate glass), medium-alkali glass fibers (8% to 12% of sodium oxide, is a boron-containing or boron-free sodium-calcium silicate glass) and high-alkali glass fibers (13% sodium oxide). and high alkali glass fiber (13% sodium oxide, sodium calcium silicate glass). p>Difference between fiberglass and asbestos:
1, different materials:
Fiberglass is a kind of inorganic non-metallic material with excellent performance, asbestos is also known as "stone wool". "is a general term for natural, fibrous, silicate-like minerals.
2, different acid resistance:
Asbestos has acid, alkali and heat resistance, and is a poor conductor of heat and electricity. Serpentine asbestos alkali resistance is better, almost not subject to alkali corrosion, but acid resistance is poor, very weak organic acids can precipitate magnesium oxide in asbestos, so that the strength of asbestos fibers decline.
Glass fibers are generally corroded only by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid.
