Common Problems of Fiberglass Mat

 

What is Glass Fiber Mat?

Glass fiber mat refers to a non-woven fabric made of glass fiber monofilaments interwoven into a mesh and cured with a resin binder. Its main characteristics are: flat surface, good dimensional stability, good uniformity, good thermal strength, and mildew resistance.

 

What is Glass Fiber Mat made of?

Glass fiber mat is generally divided into surface mat, Continuous Mat and chopped mat. Surface mat: Generally, it is made by spraying fiber filaments to improve the surface effect and reduce the influence of cloth grain on the surface; Continuous Mat: The molding method is to spray continuous fiber filaments; chopped mat: The molding method is to spray short fiber filaments;

 

What is the Difference between Surface Mat, Continuous Mat and Chopped Strand Mat?

Surface mat is generally used to improve the surface effect and reduce the influence of cloth grain on the surface; The difference between Continuous Mat and chopped mat, as the name implies, is the molding method of using short fiber filaments or continuous filaments. Continuous Mat is generally used as a diversion material, and chopped mat is used a little in the hand lay-up process to increase the interlayer force, and is used less.

 

How is Glass Fiber Needle Felt Obtained?

Glass fiber needle felt is a high-grade felt with insulation, heat insulation, fire prevention, sound insulation, air purification and other properties made by cutting glass fiber into a certain length, dividing into silk, forming into fleece, needle punching and other processes.

 

What are the Characteristics of Glass Fiber Needle Felt?

Good Thermal Insulation:

According to physical principles, the thermal conductivity of gas is small, and there are many air holes inside excellent thermal insulation materials. Glass fiber needle felt has countless tiny gases, and the fibers are arranged irregularly, which is an excellent thermal insulation material with a thermal conductivity coefficient of 0.2 to 0.040 kcal/mhr. c;

Will not burn:

The main component of glass fiber is silicide (accounting for more than 50%), which is non-flammable, non-deformable, non-embrittled, and high temperature resistant up to 7000C;

Good Sound Absorption Rate:

When sound waves penetrate glass fiber wool, the energy will be absorbed in large quantities due to friction with the fibers and air holes of different sizes. Generally speaking, the sound absorption rate is as high as 90% or more, which is a good material to prevent noise interference;

High Insulation:

Glass fiber can withstand high temperatures, has good mechanical properties, and has high chemical stability, making it the best insulating material;

High Corrosion Resistance:

Glass fiber is not afraid of strong acids and alkalis, and its functional properties will not be reduced for a long time;

Good Recovery:

Glass fiber contains countless fixed air pockets and has excellent recovery. It is not afraid of any impact or vibration, and its tensile strength is above 1.0kg.

Low Moisture Absorption Rate:

The moisture absorption rate is usually close to zero.

Lightweight and Soft:

Compared with other insulation materials, glass fiber needle felt is the lightest and softest. If installed on a machine, it can reduce its weight and vibration load.

Simple Construction:

The size can be cut according to the customer.
