Does anyone know what fiberglass is used for?

1. Glass rope twisted from glass fiber can be called the "king of ropes".

Because glass rope is not afraid of seawater corrosion and will not rust, it is very suitable for use as ship cables and crane slings. Although ropes made of synthetic fibers are strong, they will melt at high temperatures, but glass ropes are not afraid. Therefore, it is particularly safe for rescuers to use glass ropes.

2. After processing, glass fiber can be woven into a variety of glass fabrics - glass cloth.

Glass cloth is neither acid nor alkali afraid, so it is ideal for use as filter cloth in chemical factories. In recent years, many factories have used glass cloth instead of cotton cloth and sack cloth to make packaging bags. This kind of bag is not moldy or rotten, moisture-proof and corrosion-proof, durable, and very popular among people.

3. Fiberglass is both insulating and heat-resistant, so it is an excellent insulating material.

At present, most motor and electrical appliance factories in my country have used glass fiber as insulation material in large quantities. A 6,000-kilowatt turbine generator has more than 1,800 insulating parts made of glass fiber! Due to the use of glass fiber as insulating material, the performance of the motor is improved and the size of the motor is reduced. It also reduces the cost of the motor, which really kills three birds with one stone.

4. Another important use of glass fiber is to cooperate with plastics to manufacture various glass fiber composite materials.

For example, layers of glass cloth are soaked in hot-melt plastic and then pressed and formed to become the famous "glass fiber reinforced plastics." Fiberglass is even tougher than steel, does not rust and is corrosion-resistant, while weighing only a quarter of the same volume of steel.

So using it to make the shells of ships, cars, trains and machine parts can not only save a lot of steel, but also reduce the weight of the cars and ships themselves, greatly increasing the payload capacity. .

Extended information:

After years of development, my country's fiberglass enterprises have reached an upstream level in product quality, and the proportion of deeply processed products has increased year by year. The gross profit margin of leading companies in China's fiberglass industry is between 25-35%, which is significantly higher than the 10% gross profit margin of foreign giants.

The world's glass fiber industry has long been an oligopoly. As a new force, China has experienced an average annual production capacity growth rate of more than 20% in recent years. It is expected to occupy more than 60% of the global share this year and become New oligopoly in the international fiberglass market.

The rapid development of China's fiberglass industry in recent years has been driven by domestic and foreign markets. The expansion of the international market is due to both the growth of total demand and the development space left for domestic companies in the international market after international companies exited the industry due to low profit margins in the early stage.

The growth of the domestic market comes from the rapid development of the downstream consumer industry. After more than 50 years of development, China's glass fiber industry has reached considerable scale.

Compared with the international market, my country’s fiberglass products have fewer varieties and specifications and a narrow application range. But these situations also show from another perspective that there is still a large amount of market space that has not been tapped in my country's fiberglass industry, especially in some application fields, and many market segments have not even been developed at all.

In the last few years of the 20th century, under the guidance of the development strategy of the National Building Materials Administration that met the requirements of marketization, the fiberglass industry experienced significant changes in both overall output and output changes of various advanced fiberglass products. A welcome change.
