Fluoron paint cloth has excellent high temperature resistance, can maintain stable performance in high temperature environment, so it is often used in high temperature environment equipment, pipelines and other parts of the anti-corrosion and insulation, flon paint cloth also has excellent chemical corrosion resistance, can resist the corrosion of strong acid, strong alkali, aqua regia and various organic solvents, so it is often used in the chemical, petroleum and other fields of equipment, pipelines and other parts of the anti-corrosion and protection. As an anti-corrosion and protective material, the air permeability of flon lacquered cloth is one of the important factors affecting its performance. Therefore, it is very important to test the breathability of flon lacquered cloth.
The fluoron paint cloth differential pressure gas permeability meter is a common equipment commonly used to detect the breathability of flon paint cloth, and the following is introduced in detail from the test principle, application range and other aspects.
Test principle of flon lacquered cloth differential pressure gas permeability meter:
Using the differential pressure test principle, the pre-treated specimen is placed between the upper and lower test chambers and clamped. The low-pressure chamber (lower chamber) is first vacuumed, and then the entire system is evacuatedWhen the specified vacuum degree is reached, the lower chamber of the test is closed, and the high-pressure chamber (upper chamber) is filled with a certain pressure of test gas, and a constant pressure difference (adjustable) is formed on both sides of the sampleIn this way, the gas will penetrate from the high-pressure side to the low-pressure side under the action of the differential pressure gradient, and the internal pressure of the low-pressure side will be monitored and processed to obtain the various barrier parameters of the tested sample.
Importance of flon lacquered cloth differential pressure gas permeation meter application:
1.Improve the service life of flon lacquered cloth. By using this equipment, the air permeability of flon paint cloth can be effectively detected, and the protected material can be prevented from moisture, mildew and other problems, so as to improve its service life and performance.
2.Prevents flon paint cloth from being corroded. By testing the air permeability of flon paint cloth, the flon paint cloth can meet the requirements of the standard, prevent the protected material from coming into contact with corrosive substances in the external environment, and prevent corrosion.
3.Improve the stable performance of flon paint cloth. Fluoron paint cloth will be affected by temperature, humidity and other factors during use, to ensure that it has stable air permeability, can improve the performance of flall paint cloth stability.
The fluoron paint cloth differential pressure gas permeability meter is an important equipment to evaluate the quality of fluoron paint cloth, through the use of this instrument, the product quality of the flall paint cloth can be better ensured, and the service life of the flon paint cloth can be improved.
