DJF-7Waterproof membrane lap joint impermeability meter

DJF-7Waterproof membrane seam impermeability meter

DJF-7The waterproof membrane joint impermeability tester is a national standardGB45320-2025The "Safety and General Technical Specification for Building Waterproofing Membrane" has added waterproofing membrane“Impermeability of lap joints'Requirements and National StandardsGB55030-2022General Code for Waterproofing of Building and Municipal Engineering,This requirement will cover all overlapping processes such as hot melt, welding, self-adhesive, adhesive, and tape. After the formal implementation of the standard,“Impermeability of lap joints'It will become a mandatory project for the quality acceptance of waterproofing membranes. The Importance of Waterproofing:Construction of Building Waterproofing Engineering,It is an important component of construction technology,It also ensures that buildings and structures are not corroded,Construction of sub projects where the internal space is not compromised. Reasonable application of waterproof materials,Can prevent water immersion and leakage from occurring,To ensure the functional use of the building,Extend the service life of buildings.Simultaneously meet the standards of the Building Waterproofing AssociationT/CWA 302-2023Requirements for testing the impermeability of lap joints in the testing methods for building waterproofing materials engineering.

DJF-7Waterproof membrane lap joint impermeability meterTechnical Specifications

Features of the machine:

1.The machine is designed to be reasonable and easy to operate,

2.use:7Inch touch screen, simple layout, large button font, not easy to operate by mistake

3.High precision pressure sensor, accurate data, minimum reading0.01Mpa

4.Stainless steel ball valve, easy to open and close,Compared to needle valves, needle valves have a longer service life and are less prone to water leakage

5.Newly added adjustable pressure frequency function, with a test speed of approximately 0.05Mpa/min for pressurization,

6.Front door design, suitable for those who have space constraints requirements,

7.Using a silent water pump for pressurization, for lap joint testing, it has a longer service life than the air pump

8.The compression method is slightly different from other methods, as it involves tightening the nut, resulting in extremely low after-sales costs for customers in the later stage
