We will use glass fiber in many places, of course, it will also include some equipment, and some finished products, and this cannot avoid the need for human contact, then this material will harm our human body? The following editor introduces some points for attention.
Glass fiber is harmful to people. Mainly it is very easy to enter the lungs and stick to the skin, making the skin irritating and uncomfortable. Glass fiber is an organic compound. Under normal circumstances, it is not harmful to people, but because it is an organic compound, it contains harmful chemical substances, so pay more attention. The main component of glass fiber is also silica, which will "thicken" the lungs. Over time, human lungs will have problems! It is recommended to pay attention to dust and masks when processing the quality of glass fiber raw materials. If there are standards, go to the hospital on time to wash the lungs. Otherwise it will cause great harm to the human body. The pulmonary aspirations of it and coal miners are also terrifying.
At this stage, most of the raw material of glass fiber is silica, which is not harmful to the human body. But it cannot be broken down in the human body. After using it to wipe the pot, it is no problem to completely clean and tidy, otherwise the silica sludge can easily enter the appendix and cause inflammation.
Fiberglass workers mostly suffer from allergic dermatitis, but some workers can slowly bear it. This is called a "hard bottoming condition. The level of damage to the skin depends on the diameter of the chemical fiber and the surface roughness. It is recognized at this stage. Only when the diameter exceeds 5μm can it have a significant stimulating effect. Very few workers who touch glass fiber and rock wool board have allergies, but it has not been confirmed that this chemical fiber itself is an allergen.
At this stage, the key to the production of glass fiber powder is to use three production processes: cement ball mill, cone screw crusher, and jet mill. The three production processes are different according to the characteristics of the machinery and equipment, and the application places are also different.
Workers such as touching glass fibers can suffer from keratitis and conjunctivitis. In severe cases, turbid cornea and partial cysts can be seen. Chemical fibers with a diameter of 3μm or less can be cleaned from the patient's eyes. A pathological examination of the patient’s eyes showed that the corneal squamous epithelial cells grew and the mucin content of the conjunctivitis fluid increased, indicating a reflex stimulation effect. Clinical trials confirmed similar pathological changes. In other words, it is not easy to cause immediate harm at that time, but it will cause potential crises to the human body in the long term.
