In the vast field of materials science, high silicon fiber felt is like a shining star, with its unique properties and wide applications, becoming a secret weapon in high-performance materials. Now, let's delve into the world of high silicon fiber felt together.

Basic Overview of High Silicon Fiber Felt

High silicon fiber felt is an inorganic fiber material mainly composed of high-purity silicon dioxide. It is usually made from raw materials such as quartz sand through a series of complex processes such as high-temperature melting and blowing. Its fiber diameter is generally between a few micrometers and a dozen micrometers, and its appearance presents a white or grayish white felt like shape. This material has the characteristics of light weight and softness, making it easy to process and use.

Compared with traditional fiber materials, high silicon fiber felt has many advantages. For example, in terms of high temperature resistance, it can withstand temperatures of 1000 ℃ or even higher, while ordinary organic fiber materials will decompose and burn at several hundred degrees Celsius. This enables high silicon fiber felt to maintain stable performance in high temperature environments, providing a reliable solution for many industrial fields.

Excellent performance of high silicon fiber felt

1. High temperature resistance: One of the most outstanding properties of high silicon fiber felt is its excellent high temperature resistance. It can be used in high-temperature environments for a long time without significant deformation or damage. For example, in high-temperature furnaces in the metallurgical industry, high silicon fiber felt is used as insulation material, which can effectively reduce heat loss and improve energy utilization efficiency. It is also widely used in some high-temperature experimental equipment, providing a guarantee for the smooth progress of experiments.

2. Thermal insulation performance: High silicon fiber felt has extremely low thermal conductivity, which can effectively prevent heat transfer. This makes it an ideal insulation material. In the field of architecture, applying high silicon fiber felt to the insulation layer of walls and roofs can significantly reduce the energy consumption of buildings and improve indoor comfort. In the aerospace field, high silicon fiber felt is used for thermal insulation and protection of spacecraft, protecting equipment and personnel inside the spacecraft from high temperatures.

3. Chemical stability: High silicon fiber felt has good chemical stability and can resist the erosion of most chemical substances. It can maintain stable performance in corrosive environments such as acid and alkali, and is not prone to chemical reactions. Therefore, in the chemical industry, high silicon fiber felt is widely used in the manufacturing of corrosion-resistant equipment, such as insulation and protection for reaction vessels, pipelines, etc.

4. Sound absorption and noise reduction performance: The fiber structure of high silicon fiber felt has porosity, which can effectively absorb sound and reduce noise. In some places with high noise requirements, such as recording studios, cinemas, etc., high silicon fiber felt is used as sound-absorbing material to create a quiet environment.

Production process of high silicon fiber felt

The production process of high silicon fiber felt is relatively complex, mainly including raw material preparation, melt blowing, fiber collection, and post-treatment.

Raw material preparation is the foundation for producing high silicon fiber felt. High purity quartz sand and other raw materials are usually selected, and after cleaning, crushing, and other treatments, they are made into raw material powders that meet the requirements. Then the raw material powder is sent to a high-temperature furnace for melting, to achieve the appropriate viscosity and flowability.

Melting spray is a crucial step. In a high-temperature furnace, the melted raw materials are blown into small fibers by a special blowing device with high-speed airflow. During the blowing process, the diameter and length of the fibers can be controlled by adjusting the blowing parameters.

Fiber collection is the process of collecting blown fibers together to form a felt like structure. Usually, negative pressure collection is used to adsorb fibers onto the collection net, forming a uniform felt layer.

Post treatment includes processes such as heat treatment and impregnation. Heat treatment can further improve the performance of fiber felt, making it more stable. Immersion treatment can endow fiber felt with some special properties, such as waterproofing, fireproofing, etc.
