Air Bubble Tester for BOPET Film Leaf Disc - Reliable China Suppliers & Factory Quality Assurance
The maximum equivalent capillary diameter in the test piece which is calculated from the measured minimum pressure required to force the first bubble of gas through the test piece (under standardized conditions) impregnated with a liquid.
Application
- Used as factory-entry quality detection for new disc filter.
- After the disc filter is used, whether it is damaged.
Test Indicators
- 1. First bubble point The bubble test pore size corresponds to the minimum differential pressure at which constant bubbling first occurs.
- 2. The uniformity of distribution of pores These particular definitions should be agreed between the supplier and the user. Moreover, the uniformity of distribution of pores approaching the maximum pore size may be observed by gradually increasing the gas pressure. Cracks and clogged areas are easily discerned by this operation.
Model: BPT-B Sample Details
Technology Performance
It is pressed the disc filter by cylinder.
Digital display the bubble pressure and flow.
The equipment is equipped with automatic air exhaust device, avoiding environmental pollution caused by the volatilization of the IPA.
The equipment is equipped with the circulation filtration of IPA, extending IPA usage time.
The device is provided with a visual sliding door, making observation more convenient.
The equipment is equipped with a storage tank; after the test is completed, the test liquid is returned to the liquid storage tank.
Frequently Asked Questions (FAQ)
What is the primary application of the Bubble Point Test?
The test is primarily used for factory-entry quality detection of new disc filters, as well as checking whether a disc filter has been damaged after usage.
How is the bubble test pore size determined?
It is calculated using a mathematical formula based on the measured minimum pressure required to force the first bubble of gas through a liquid-impregnated test piece under standardized conditions.
What is the "First bubble point" indicator?
The first bubble point corresponds to the minimum differential pressure at which constant bubbling first occurs on the surface of the test piece.
How can cracks and clogged areas be identified during testing?
By gradually increasing the gas pressure, operators can observe the uniformity of pore distribution approaching the maximum pore size, making cracks and clogged areas easily discernable.
What disc filter specifications can the Model BPT-B accommodate?
The Model BPT-B is designed for disc filters ranging from φ177.8mm to 306mm in diameter, with a filtering accuracy between 5um and 60um.
How does the Model BPT-B manage IPA (Isopropyl Alcohol) during testing?
It features an automatic air exhaust device to prevent environmental pollution from IPA volatilization, circulation filtration to extend IPA usage time, and a storage tank that retrieves the test liquid once testing is complete.
