2, skin hazards
Workers exposed to glass fibers generally have contact dermatitis, which is obviously irritating when the fiber diameter exceeds 5 microns.
3. Damage to eye mucosa
Workers exposed to glass fiber may suffer from conjunctivitis and keratitis, and in severe cases, corneal opacity and local swelling can be seen.
Extended data
Glass fiber is a kind of inorganic nonmetallic material with excellent performance, and there are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, while its disadvantages are brittleness and poor wear resistance. It is made of pyrophyllite, quartz sand, limestone, dolomite, xonotlite and magnesite through high temperature melting, drawing, winding and weaving.
The diameter of monofilament ranges from several microns to more than twenty microns, which is equivalent to 1/20- 1/5 of a hair filament. Each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. Glass fiber is usually used as reinforcement, electrical insulation and thermal insulation in the fields of national economy such as composite materials and circuit boards.
