Whether silica fabric is harmful?

Most of the glass fibers are made of silica, which is not toxic to the human body.

The main components of glass fiber are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the alkali content in the glass, it can be divided into alkali-free glass fiber (sodium oxide 0% ~ 2%, belonging to aluminum-borosilicate glass), medium alkali glass fiber (sodium oxide 8% ~ 12%, belonging to boron-containing or boron-free soda-calcium silicate glass) and high-alkali glass fiber (sodium oxide more than 13%, belonging to soda-calcium silicate glass).
Fiberglass itself is non-toxic, but it may have some effects on human health during contact. Specifically, when glass fibers are released into the air in the form of tiny particles or fibers, people may inhale these fibers if they are exposed to such an environment for a long time. While most fibre is naturally excreted, some fibre may remain in the lungs and accumulate over time that can pose a potential threat to lung health.

Fiberglass Notes:

1. The diameter of conventional glass fiber monofilament is more than 9-13 microns, and the glass fiber floats below 6 microns can directly enter the lung tube and can cause respiratory consequences, so special attention should be paid to the fact that most of the glass fiber floats below 6 microns are imported. Wear a professional mask during production operations. If exposed to it regularly, it may be inhaled into the lungs.

2. If the body is stained with fiberglass cloth, the skin will be allergic and itchy, but usually there will be no big harm, and the bad skin may take up small packets, which is an allergy phenomenon, just take some anti-allergic medicine.

3.If it is difficult to remove it on the clothes, pat it a few times in a windy place, and after washing and drying, it is easier to remove it with a twig and other patting, so pat it a few times.

Overall, although glass fibers are not toxic by themselves, the long-term effects of their fine particles and fibers inside and outside the human body still need to be paid enough attention. Therefore, when coming into contact with glass fibers, necessary protective measures should be taken to reduce the potential harm to the human body.
