What are the disadvantages of fiberglass to the body

If it pierces inside, it will cause a lot of discomfort.

But fiberglass is a great material.

Look at the problem in two parts.

Characteristics of glass fiber:

The general concept of glass is a hard and fragile object, and it is not suitable as a structural material, but if it is drawn into filament, its strength is greatly increased and it has softness, so it can finally become an excellent structural material after combining the resin to give the shape. As can be seen from Figure 1, the strength of the glass fiber increases as its diameter decreases. As a reinforcing material, glass fiber has the following characteristics, which make the use of glass fiber far more extensive than other types of fiber, and the development speed is far ahead of its characteristics are listed below

1) High tensile strength and small elongation (3%).

2) High elasticity coefficient and good rigidity.

3) The elongation within the elastic limit is large and the tensile strength is high, so the impact energy absorption is large.

4) It is an inorganic fiber, which is non-flammable and has good chemical resistance.

5) Low water absorption.

6) Scale stability and heat resistance are good.

7) Good processability, can be made into strands, bundles, felts, weaving and other different forms of products.

8) Transparent and transparent to light.

9) Completed the development of a surface treatment agent with good adhesion to resin.

10) **Cheap.

The teacher never asks us to touch the fiberglass in case it is punctured, and it is easy to cause allergies

Take a tape and see if it doesn't work, and if it doesn't work, consult a doctor.

The main component of glass fiber is also silica, which will "calcify" the lungs, and over time, the human lungs will have problems. It is recommended to pay attention to dust prevention and wear a mask when working in a factory made of glass fiber raw materials. If possible, go to the hospital regularly to wash your lungs.

Otherwise, it will bring great harm to the human body.

Take a shower with hot water and wash with a towel in addition. Hot water allows the pores to open.

Inhalation is not good for the lungs.

It will be sucked like lungs, causing cancer! It's more dangerous, but I know it.

I also come into contact with it often, so I have to make sure not to suck it in, as for the one that pierces the body, the danger is not very great.

Some fiberglass materials are harmful to the human body, but most of the fiberglass materials are relatively friendly to the human body, and generally speaking, there will be no damage to health.

When glass fiber is used as a reinforcing material for reinforced plastics, the biggest feature is its high tensile strength. The tensile strength is g d in the standard state and g d in the wet state. Density.

It has good heat resistance, and has no effect on strength when the temperature reaches 300 °C. It has excellent electrical insulation, is a high-grade electrical insulating material, and is also used for thermal insulation materials and fireproof shielding materials. Generally, it is only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid.

Uses of Fiberglass:

Fiberglass can be made into glass rope, which is very strong and safe, and can also prevent corrosion. Fiberglass is processed to weave a variety of glass cloths, and factories use glass cloth instead of cotton cloth to make packaging bags, which are very durable.

Another important use of glass fiber is to cooperate with plastics to make various glass fiber composite materials, such as glass fiber reinforced plastic. When glass is drawn into filaments, its strength is greatly increased, and it has a certain degree of flexibility, and if it is given shape with resin, it can be used as an excellent structural material.

The above content refers to Encyclopedia - Fiberglass.

1. It is mainly easy to enter the lungs and prick on the lungs to make the itching uncomfortable.

2. Glass fiber is an organic matter, which is generally not harmful to people, but because it is an organic matter, it contains substances that are harmful to people, so it is necessary to pay more attention.

3. The main component of glass fiber is also silica, which will make the lungs "calcify", and after a long time, people's lungs will have problems! It is recommended to pay attention to dust prevention and wear a mask when working in a factory made of glass fiber raw materials. If possible, go to the hospital regularly to wash your lungs.

Otherwise, it will bring great harm to the human body.

4. It and the coal miner's lung sucking disease is even more terrible.

Fiberglass is harmful to the human body.

Most of the glass fibers are made of silica, which is not toxic to the human body. However, it cannot be decomposed in the human body, and there is no problem with rinsing it thoroughly after wiping the pot, otherwise the silica residue will easily get the appendix after entering 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-lime silicate glass).

Difference Between Fiberglass and Asbestos:

1. The material is different

Glass fiber is an inorganic non-metallic material with excellent performance, asbestos, also known as "asbestos" is a general term for natural fibrous silicate minerals.

2. Different acid resistance:

Asbestos is resistant to acids, alkalis and heat, and is a poor conductor of heat and electricity. Among them, serpentine asbestos has good alkali resistance, almost not corroded by alkali, but the acid resistance is poor, and very weak organic acids can precipitate the magnesium oxide in asbestos, so that the strength of asbestos fibers decreases.

Glass fibers are generally only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid.

01 Harmful.

At present, most of the material composition of glass fiber is silica, which is not toxic to the human body. But it cannot be broken down in the human body. There is no problem with rinsing the pan thoroughly after wiping the pot with it, otherwise the silica residue will easily enter the appendix after entering the human body and cause inflammation.

Glass fiber (original name in English: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance, with a wide range of advantages, good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantage is brittleness and poor wear resistance. It is pyrophyllite, quartz sand, limestone, dolomite, boronite, boronite seven kinds of ore as raw materials by high-temperature melting, drawing, winding, weaving and other processes, the diameter of its monofilament is a few microns to more than 20 microns, equivalent to a hair of 1 20-1 5, each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments.

Glass fiber is commonly used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy.

Its main components 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-lime silicate glass).
