Low pressure waterproofing membrane impermeability meter

1、

DTS-D typeLow pressure waterproofing membrane impermeability meterIt is based on GB/T3281.10-2007 in our factory《Test method for building waterproofing membrane 第10partImpermeability of asphalt and polymer waterproofing membranesHow to translateDesign and manufacture according to relevant standards. Suitable for measuring low-pressure applications of asphalt and polymer rollsFor example: roof, base layer, air barrier layer, with easy operation. Advantages such as stable performance.

Low pressure waterproofing membrane impermeability meter

Adopting water pressure self-control and air cylinder pressurization, it can be used by testing units, scientific research, construction, production, design and teaching departments under a test pressure not exceeding 60Kpa.

1. Test pressure: 0-60kPa2. Measurable quantity: 3 pieces (1 set)3. Inner diameter of permeable disc:

φ

150mm

1.4. Test water temperature: 20 ℃± 53、 【 Usage 】

2.Remove the pressure plate so that the upstream surface of the specimen faces downwardsOn the second layer, laboratory filter paper is placed, and on the third layer, a moisture mixture is placed, consisting of a mixture of fine white sugar (rock sugar) (99.5%) and methylene blue dye (0.5%) The fourth layer is used to place laboratory filter paper Place glass panels on the fifth layer Then use a pressure ring to tighten it

close

0 Drain valve, open the inlet valves of the three permeable plates 1.2.3 Open exhaust valve 4.5.6. Inject purified water into the pressurized container at approximately 2/3 position Raise the pressurized container and pay attention to the reading on the pressure gauge If water overflows from the exhaust pipe, the exhaust valve can be closed

3. If 10Kpa is required, the pressure can be controlled by a drain valve or the pressurized container can be reduced If the lifting and pressurization container cannot reach the pressure when 60Kpa is required, an air pump (self provided) can be used to assist in pressurization Close the inlet valve switch during the experiment Observe the pressure on the pressure gauge Be careful not to inflate slowly and overload the pressure After the specified time, open the drain valve and remove the specimen, repeat the above process for the next test

1.4. Check the test piece and observe if there is any discoloration on the filter paper. If there is obvious water seeping into the filter paper on top of the test piece and discoloration occurs, it is considered unqualified All specimens that are impermeable within the specified time are considered to have passed the impermeability test
