The manufacturer of bitumen flashing tape will show you how to test the permeability of bituminous tape

The manufacturer of bitumen flashing tape tells you that the bitumen tape product is a good anti-corrosion tape, and it can also achieve the ideal anti-corrosion effect. Everyone knows how to use the tape. Today the manufacturer of bitumen flashing tape teaches you how to test the air permeability of asphalt anti-corrosion tape. Welcome to follow.

Generally speaking, the air permeability of bituminous tape is mainly expressed by the gas permeability and the gas permeability coefficient. The manufacturer of bitumen flashing tape tells you that if the permeability of bitumen anticorrosive tape is tested, it is also tested on a special instrument. Asphalt tape separates the high-pressure and low-pressure chambers together, and seals them well. There is a test gas of 105Pa in the high-pressure chamber. The manufacturer of bitumen flashing tape tells you to first extract the air in the low-pressure chamber with a vacuum pump during the test, the pressure is close to zero, and then use the pressure measurement. The gauge detects the pressure increase in the low-pressure chamber. The allowable stretch of asphalt tape is the stretch applied to maintain various required characteristics in a certain application. The manufacturer of bitumen flashing tape tells you that stretching is constantly changing with the application.
As for how to detect the air permeability of asphalt anticorrosive tape, I will introduce you so much first, you can try it, and the supplier of bitumen flashing tape will continue to introduce related content to you later, welcome to continue to pay attention.
