Paint film filter integrity tester
Among them: D - diffusion flow value (ml/min)
The pressure corresponding to the first opened hole is the bubble point pressure, and the aperture corresponding to this pressure is the large aperture;
Test pressure: 3000 mbar
The built-in thermal printer avoids the risk of particle and ink contamination, and can maintain clear handwriting for more than 10 years under appropriate conditions;
When the gas pressure on the high-pressure side of the sample is greater than the capillary pressure and surface tension inside the sample membrane pores, it is released from the other side of the sample, and the wetting solution in the capillary pores will be pressed out to the low-pressure side of the sample by the gas pressure. At this time, the pressure on the high-pressure side of the sample is considered as the bubble point pressure, and the phenomenon should be the appearance of a series of continuous bubbles in the sample.

Paint film filter integrity tester
The product wetting solution does not refer to water, nor is it a product or process fluid, but rather a solvent. After product wetting, the integrity test results for the same filter material may vary due to differences in the surface tension coefficient of the wetting solution. Testing the solubility and diffusion ability of gases in diffusion flow can also result in inconsistent test results. For this system, the recommended infiltration solution is a mixture of fluorocarbon, anhydrous ethanol, or 60% isopropanol and water.
Added the display curve of diffusion flow rate pressure, achieved the display and printing function of three curves, optimized the intake control unit, and significantly increased the intake speed and stability;

Satisfy offline online testing by using pressure sensors with higher precision and lower deviation bands to improve the testing accuracy of the instrument;
Wetting liquid stays in the porous channels of the membrane due to capillary action. This capillary action increases as the pore size decreases. The gas pressure depending on the pore size of the membrane forces the liquid out of the pore. The pressure at this point is called the "bubble point" or simply BP. The liquid will come out of the large pore size on the membrane. Therefore, the BP value of the filter element is also related to the surface tension of the membrane material (the wetting angle varies depending on the material), especially the wetting liquid. Liquids with low surface tension, such as organic solvents, detergents, and emulsifiers, have lower BP values. The BP value is also related to the temperature of the wetting medium. The bubble point testing method is particularly suitable for integrity testing of circular film.

Taking a certain membrane material as an example, the membrane is fully wetted with a liquid that can be wetted with it. Due to the presence of surface tension, the wetting liquid will be? Bound within the pores of the membrane;
Due to the molecular attraction of interfacial tension, the infiltrating liquid is firmly locked in the micropores of the filter material.
