Detailed description of the invention
Being described in further detail the goal of the invention of the present invention with specific embodiment below in conjunction with the accompanying drawings, embodiment is not
Can repeat one by one at this, but the most therefore embodiments of the present invention are defined in following example.
Embodiment one
As shown in Figures 1 to 4, a kind of porous hydrophobic material water repellent system safety testing device, including being provided with the transparent organic glass of graduation mark
Glass water pipe 1, the lucite cope match-plate pattern 2 being bolted and lucite lower bolster 3 and be arranged on described organic glass
Lucite regulation pad 3 between glass cope match-plate pattern 2, lucite lower bolster 3, described lucite cope match-plate pattern 2, lucite
The surrounding of lower bolster 3, lucite regulation pad 3 is evenly arranged with bolt hole；It is provided with in the middle of described lucite cope match-plate pattern 2
The manhole being connected by sealant sealing with described lucite water pipe 1, is arranged in the middle of described lucite lower bolster 3
There is the circular counter bore for accommodating the test agent 6 that can meet water variable color, be provided with to be measured in the middle of described machine glass regulation pad 3
The consistent cavity of the shape of porous hydrophobic material 7.
Specifically, the shape of the cavity arranged in the middle of described lucite regulation pad 3 includes rectangle, circle, this
Embodiment uses rectangle.
Specifically, the bottom of described circular counter bore is additionally provided with passage 5, and passage prevents because air is close for ventilative
The measurement error closed and cause.
The lucite water pipe 1 internal diameter 21mm, external diameter 25mm, a length of 500mm of the present embodiment with scale, scale
Instruction water-retention water-column, lucite water pipe 1 is through lucite cope match-plate pattern 2, and uses close with lucite cope match-plate pattern 2
