What is a Frazier air permeability tester?

 

The principle of the Fraser gas permeability tester is to evaluate the gas permeability of the material by measuring the flow velocity of the gas on the material. During the test, the material to be tested is sandwiched between two circular fixtures to form a closed test chamber. Then, a certain amount of pressure is applied to one side of the test chamber to cause gas to flow through the material from the other side. The pressure difference and flow across the test chamber are measured and recorded.

 

According to the test results of the Fraser air permeability tester, the air permeability of the material can be evaluated. Permeability refers to the ability of gas to pass through the material, usually expressed by Permeability. Air permeability refers to the gas flow per unit area per unit time, usually in cubic meters/square meters/second (m³/m²/s). The higher the air permeability, the better the breathability of the material.

 

The advantages of the Fraser air permeability tester are simple operation, accurate and reliable test results. It can be used on different types of materials including textiles, paper, plastic films and more. In the textile industry, the Fraser air permeability tester is often used to evaluate the air permeability of fabrics, such as cotton, nylon, polyester, etc. In the filtration industry, it can be used to evaluate the air permeability of filter materials, such as air filters, liquid filters, etc. In the paper industry, it can be used to evaluate the air permeability of paper, such as packaging paper, filter paper, etc.

 

Fraser air permeability tester has important application value in scientific research, production and quality control. Researchers can test the air permeability of different materials and study the relationship between the structure of the material and the air permeability, so as to provide a basis for the improvement and optimization of materials. Manufacturers can test the air permeability of the product to ensure that the product meets the design requirements and customer needs. Quality control personnel can judge whether the quality of the product is qualified by testing the air permeability of the sample, and whether there is a problem of unstable air permeability.

 

In summary, the Fraser Permeability Tester is an important instrument for measuring the gas permeability of materials. It evaluates the gas permeability of materials by measuring the flow velocity of gas on materials, and is widely used in textile, filtration, paper, plastic and other industries. It has the advantages of simple operation, accurate and reliable test results, and has important application value for scientific research, production and quality control.
