Embodiment 1

[0041] First prepare the detection film 6, the components of the detection film 6 are in grams:

[0042] Ammonium molybdate: 100g-130g,

[0043] Hydrochloric acid with a mass concentration of 18%: 10-13 ml,

[0044] Oxalic acid: 100-120 grams,

[0045] Rosin: 100-150 grams,

[0046] 1-Amino-2-naphthol-4-sulfonic acid: 3 grams,

[0047] Titanium dioxide: 70-90 grams,

[0048] Methanol: 400-500ml

[0049] Sulfurous acid with a mass concentration of 8%: 700-750 ml;

[0050] The preparation is carried out as follows: mix 120 grams of ammonium molybdate, 110 grams of oxalic acid, 4 grams of 1-amino 2-naphthol 4-sulfonic acid, 750 grams of sulfurous acid and 11 milliliters of hydrochloric acid to obtain a precipitate, mix 130 grams of rosin, oxalic acid 110 grams of methanol and 450 milliliters of methanol are made into an intermediate solution, and the precipitate is dissolved in the intermediate solution, and then 70 grams of titanium dioxide are added, stirred and mixed to ...

Embodiment 2

[0074] The difference with the above-mentioned Example 1 is the preparation of the detection film, and its color-changing coating coating solution is carried out according to the following formula:

[0075] Mix 130 grams of ammonium molybdate, 120 grams of oxalic acid, 3 grams of 1-amino 2-naphthol 4-sulfonic acid, 720 sulfurous acid and 10 ml of hydrochloric acid to obtain a precipitate. Mix 150 grams of rosin, 120 grams of oxalic acid and 500 ml of methanol Prepare an intermediate solution, dissolve the precipitate in the intermediate solution, then add 80 grams of titanium dioxide, stir and mix to obtain a color-changing coating solution; apply the color-changing coating solution to the upper end surface of the sample, After drying, the detection film is obtained.

[0076] The detection principle and detection steps are the same as in Example 1.

Embodiment 3

[0078] The difference with the above-mentioned Example 1 is the preparation of the detection film, and its color-changing coating coating solution is carried out according to the following formula:

[0079] Mix 100 grams of ammonium molybdate, 100 grams of oxalic acid, 5 grams of 1-amino 2-naphthol 4-sulfonic acid, 700 grams of sulfurous acid and 13 milliliters of hydrochloric acid to obtain a precipitate. Mix 100 grams of rosin, 100 grams of oxalic acid and 450 milliliters of methanol Prepare an intermediate solution, dissolve the precipitate in the intermediate solution, then add 90 grams of titanium dioxide, stir and mix to obtain a color-changing coating solution; apply the color-changing coating solution to the upper end surface of the sample, After drying, the detection film is obtained.

[0080] The detection principle and detection steps are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention belongs to the technical field of concrete impermeability detection, in particular to a fully automatic impermeability test device for concrete samples. It includes a high-pressure water filling part, a sample detection part, a data processing part and a control part, the high-pressure water filling part injects high-pressure water into the sample, and the sample detection part detects the color change of the sample caused by water seepage, The data processing part converts the color change of the sample into a digital signal and judges it. The sample detection part includes a sample mold, a detection film and a sampling mechanism, and the sampling mechanism includes a top cover, an LED matrix light and a color sensor, and the LED matrix light and the color sensor are fixed inside the top cover On the side, the LED matrix lamp is connected to the light source driving circuit, and the signal output terminal of the color sensor is connected to the control part. It can realize the automation of concrete impermeability detection, save labor and improve the accuracy of detection.

Description

technical field [0001] The invention belongs to the technical field of concrete impermeability detection, in particular to a fully automatic impermeability test device for concrete samples. Background technique [0002] In the construction industry, concrete is widely used, and the penetration of concrete has a huge impact on both the construction of the construction project and the safety of the building after delivery. In recent years, related construction quality disputes and safety accidents have been frequently reported by the media. , has aroused great attention and widespread attention from the society, so the research on the impermeability of concrete is a very important topic in the construction industry at present. Only by correctly understanding the impermeability of concrete can the healthy and sustainable development of the construction industry be guaranteed. [0003] Concrete is a porous body with different pore sizes (10~500μm). When there is a pressure diffe...
