When we cut and process FRP, it is easy to produce a large amount of dust composed of broken glass fibers. After dust touches the skin, it is prone to itching, which makes people feel extremely uncomfortable。The glass fiber cloth is also woven with glass fiber, so once the fiber breaks and the glass dust is dipped on the human skin, it is more itchy. To put it bluntly, the microstructure of glass fiber includes rhombus, circle, triangle, polygon and so on. Its sharp edges and corners are just like glass blocks hurting people, so the glass dust generated by glass fibers should not touch people's skin as much as possible.
Individuals should take protective measures, such as wearing rubber gloves, sealing the cuffs with transparent glue, wearing dust masks and dust hats. Once you feel itching, do not try to scratch it. Beware of the continuous penetration of glass dust particles into the deep tissues of the skin, causing the skin to become more itchy and ulcerated.
There are two commonly used methods for removal. The mechanism of action is similar. The glass fiber can be inserted because of external force. For example, when the hand is pressed on the glass fiber, the reason for the failure is that the skin is generally hard and the resistance is large. The external force of muscle contraction or squeeze is not strong enough to push him out.
1. The first method is to insert the glass fiber that has nodding on the outside. Use medical tape or medicinal plaster to stick the fiber into the place. After the tape stands on, it will prevent the skin from perspiration and evaporation. When it becomes softer, the pulling resistance is reduced. After the adhesive tape is bonded to the exposed glass fiber, it can generally be removed by peeling it off forcefully.
2. The second method, if you are very unlucky and have a lot of strength when you plunge into it, and when it breaks, there is no fiberglass head left outside. What should I do? After I was pierced many times, I got the conclusion of long-term exploration. It is labor. Add washing powder to the clothes you want to wash at home, soak them in hot water, and wash them while it’s hot. In this process, the epidermis is greatly softened, and the resistance of the glass filaments is reduced. The washing powder water enters the glass filaments to increase the lubrication and reduce In order to reduce the resistance, the muscle contraction of the hand washing clothes will cause external force to squeeze the glass fiber. If it is not large enough, after washing, you can also use your other hand to squeeze the part to be pierced. The direction of squeezing should depend on the direction of penetration. , Squeeze from the opposite direction or squeeze on both sides, and slowly you will find that the glass fiber is exposed. At this time, you can use tweezers or refer to the first method to stick it with tape and peel it off.
3. The third method, if you run out of various methods, you still can't get out. You are a person who can't tolerate sand in your eyes and thorns in your flesh, and a person who feels anxious and uncomfortable every day. Then I suggest you go to a big hospital. , Find microsurgery, the instrument can see those things and can get them out.
