Water-proof membrane vacuum water absorber is a testing instrument for detecting water absorption of petroleum asphalt paper tire linoleum and linoleum waterproof membrane.Can also be used for various tiles water absorption test.Be sure to read the instructions carefully before use.It is operated by**experimental personnel to avoid injury caused by improper operation.For more information,please contact our customer service staff.
Waterproof membrane vacuum water absorber is provided by Shanghai Rongjida Instrument Technology Co.,Ltd.and developed in accordance with the**standard(test method for asphalt waterproofing membrane GB328.4-89).The supplier is responsible for free maintenance.If due to improper operation or man-made damage,our company should also provide repair and replacement services,and the costs incurred by our company will be charged at our discretion.
Technical parameters of vacuum water absorption meter for waterproof membrane;
1.Vacuum pressure and negative pressure range;0-(900000+1300)Pa
2.Power supply voltage:220v50hz
Structural features of waterproof membrane vacuum water absorber:
It is mainly composed of pumping part,test control part and sample container part.The control system is convenient and flexible,easy to operate,and the whole machine is arranged reasonably and clearly.
Installation and commissioning of waterproof membrane vacuum water absorption instrument:
When opening the box,pay attention to whether the various glass containers are damaged,whether the vacuum pump is injected to the red dot position,and the joints are connected to avoid loosening.Vacuum should be applied to each valve core.Install the thermometer and rubber plug on the water bottle,and then connect the power supply.
Test preparation for vacuum water absorption meter for waterproof membrane:
A.Exhaust system inspection(open the water injection valve when inflating)
Pour a small amount of water into the water storage bottle to close the water injection valve,open the pressure regulating valve and the water suction valve,and start to make the vacuum degree of the vacuum dryer reach the specified amount.The air extraction system is free from leaks.
B.Test piece processing:(coiled material as an example,ceramic tiles refer to**Relevant testing standard test)Time is not sealed,brush the surface of floating insulation material,and accurately weigh(W1)
Note for waterproof membrane vacuum water absorber:
1.Vacuum and negative pressure are strictly prohibited to exceed the meter range and damage the meter.
2.Regularly apply vacuum grease to the valve plug and the interface of the dryer.
3.Water dripping on the vacuum grease of the dryer needs to be sucked with filter paper.
4.Air leakage caused by loose spool.
5.Change the pump oil regularly
