What Are Vitreous Floaters?

Glass fiber gingham is a roving plain weave fabric, which is an important base material for hand layup glass fiber reinforced plastic. The strength of the gingham is mainly in the warp and weft directions of the fabric. For places that require high warp or weft strength, it can also be woven into a unidirectional cloth. Warp cloth, single weft cloth.

The difference between glass fiber cloth and glass material

The difference between the main materials of glass fiber cloth and glass is not large, mainly because of the different material requirements during production, so there are some differences in the formula. Flat glass silica content is about 70-75%, and glass fiber silica content is generally below 60%.

Glass is an inorganic material that has been melted at a high temperature (above 800 degrees, and daily glass is generally melted at 1100 degrees). It does not undergo chemical changes below the softening point temperature. Above the softening point temperature, it just softens, melts or decomposes, and does not burn.

Glass fiber cloth is made of glass with extremely thin glass filaments. At this time, the glass filaments have good flexibility. The glass fiber is spun into yarn and then passed through a loom to be woven into a glass fiber cloth. Due to the extremely thin glass filaments and the extremely large surface area per unit mass, the temperature resistance has decreased. Just like melting a thin copper wire with a candle.

But glass doesn't burn. The combustion we can see is actually to improve the performance of glass fiber cloth, the resin material coated on the surface of the glass fiber cloth, or the impurities attached. Pure fiberglass cloth or some high-temperature resistant coatings can be used to make products such as fire-resistant clothing, fire-resistant gloves, and fire-resistant blankets. However, if it comes into direct contact with the skin, the broken fibers are more irritating to the skin and can be itchy.

Glass fiber cloth matters needing attention

Generally, the diameter of the conventional glass fiber monofilament is more than 9-13 microns, and the glass fiber floats below 6 microns can directly enter the pulmonary tube, which can cause respiratory diseases, so it should be paid special attention. Generally, most of them are imported below 6 microns. Professional masks must be worn during production operations. May cause aspiration into the lungs if caused by frequent contact, causing pneumoconiosis.

If the fiber is attached to the body, if the skin is bad, it will cause allergies and itching, but generally it will not cause serious harm. If the skin is not good, it may be a small bag. It is an allergic phenomenon. .

If it is difficult to remove the clothes, tap a few times in a windy place. After washing, drying, tapping with a branch, etc., will be easier to remove. Tap a few more times! ^[2]
