A specialized testing equipment for detecting the water absorption of petroleum asphalt paper based felt and felt waterproofing membranes. It can also be used for various ceramic tile water absorption tests.

Experimental preparation:

Check the air extraction system (open the water injection valve again during inflation)

Pour a small amount of clean water into the water storage bottle, close the water injection valve, open the pressure regulating valve and water pumping valve, and start to make the vacuum degree of the vacuum dryer reach the specified amount;

At this point, open the water injection bottle and pump it into the dryer to check that the pumping system is unobstructed and there is no air leakage.

Sample processing:

(For example, for roll materials, please refer to the relevant national testing standards for ceramic tiles) If the time is not sealed, brush off the floating isolation material on its surface and accurately weigh (W1)

Precautions for vacuum water absorption instrument for rolled glazed tiles:

Vacuum degree negative pressure is strictly prohibited from exceeding the range of the meter and damaging the meter.

Regularly apply vacuum grease to the valve plug and dryer interface.

Dropping water on the vacuum grease of the dryer requires sticking it with filter paper.

Leakage caused by loose valve core array.

Regularly replace pump oil

Instructions for using the vacuum water absorption instrument for roll glazed tiles:

Installation and debugging

When opening the box, pay attention to whether various glass containers are damaged, whether the vacuum pump is filled to the red dot position, and whether the joints are connected to avoid looseness. Each valve core should be vacuum coated. Install the thermometer and rubber plug on the water storage bottle, and then connect the power.

Experimental preparation

A. Check the air extraction system (open the water injection valve again during inflation)

Pour a small amount of clean water into the water storage bottle, close the water injection valve, open the pressure regulating valve and water pumping valve, and start to make the vacuum degree of the vacuum dryer reach the specified amount;

At this point, open the water injection bottle and pump it into the dryer to check that the pumping system is unobstructed and there is no air leakage.

B. Sample processing: (For example, for roll materials, refer to relevant national testing standards for ceramic tiles) Do not seal the edges for a long time, brush off the floating isolation material on the surface, and accurately weigh (W1).

Technical parameters of vacuum water absorption instrument for rolled glazed tiles:

Vacuum degree negative pressure range; 0- (900000+1300) Pa

Power supply voltage; 220v50hz

External dimensions; 580 * 495 * 445mm

Structural characteristics of vacuum water absorption instrument for rolled glazed tiles:

It mainly consists of the suction part, experimental control part, and sample container part. The control system is convenient, flexible, and easy to operate. The overall layout of the machine is reasonable and the hierarchy is clear.

Installation and debugging:

When opening the box, pay attention to whether various glass containers are damaged, whether the vacuum pump is filled to the red dot position, and whether the joints are connected to avoid looseness. Each valve core should be vacuum coated. Install the thermometer and rubber plug on the water storage bottle, and then connect the power.
