Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle

Designed and manufactured according to the relevant standards of GB/T328.10-2007. It is suitable for the determination of low pressure occasions of asphalt and polymer coils, such as: roofing, base layer, gas barrier layer. It has the advantages of simple operation, stable performance, etc. Pressure automatic control and air cylinder pressurization, in the case of test pressure not more than 60Kpa, available for testing units. Scientific research, construction, production, design teaching and other departments.

Technical Parameters:

1, test pressure: 0-60Kpa

2, can be tested: 3 (1 group)

3, the diameter of the permeable tray: Φ150mm

4, test water temperature: 20 ° C ± 5

Waterproof membrane impervious instrument use method:

1. Remove the platen so that the test piece faces down. The second layer is placed on the laboratory filter paper, and the third layer is placed in a moisture mixture consisting of fine white sugar () (99.5%) and methylene blue dye (0.5 Mixture of %). Place the filter paper for the laboratory on the fourth layer. Place the glass plate on the fifth layer. 5mm thick for water pressure ≤10Kpa, 8mm thick for ≤60Kpa.

2. Close the drain valve as shown (page 2). Open the inlet valve. Open the inlet valve of the three permeable trays. 2.4.5. Open the vent valve 1. and the pressure gauge valve 3. Put the pressurized container Inject pure water into the 2/3 position. Pay attention to the indicated value of the pressure gauge. The water in the exhaust pipe can be closed to close the valve.

3. For 10Kpa available drain valve control pressure. Close the inlet valve switch when the pressure test is 60Kpa. Use the pump to assist the pressure. Observe the pressure of the pressure gauge. Pay attention to the pressure and do not overload the pressure. Open the drain valve after the specified time. Remove the test piece and repeat the above procedure for the next test.

4. Check the test piece and observe whether the filter paper on the top is discolored. The test piece has obvious water seepage and the filter paper is discolored. It is considered to be unqualified. All the test pieces are impervious to the water at the specified time.
