Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to a testing device for the permeability resistance of magnesium oxide board. Background Technology

[0002] Magnesium oxide board (also known as magnesium oxide board) is a stable magnesium-based cementitious material made from a ternary system of magnesium oxide, magnesium chloride, and water, formulated with modifiers. It is a new type of non-combustible decorative material reinforced with medium-alkaline fiberglass mesh and filled with lightweight materials. Processed using a special manufacturing process, it features fire resistance, water resistance, odorlessness, non-toxicity, frost resistance, corrosion resistance, crack resistance, colorfastness, non-combustibility, high strength, lightweight, easy construction, and long service life. Currently, there is no dedicated testing device for the water permeability resistance of magnesium oxide board. Generally, a water spray method is used, where water is continuously sprayed onto one side of the board, and the other side is observed for significant wetting or water droplets. This method is relatively water-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a device for testing the permeability of magnesium oxide boards in order to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a glass magnesium board penetration resistance testing device, including a bracket and a water basin. The upper part of the water basin is open and a sealing ring is provided around the opening. A basin rim is provided on the outer side of the upper part of the water basin. Multiple second threaded holes are provided on the basin rim. Rotating shafts extending in a horizontal direction are provided on both sides of the water basin. The rotating shafts are rotatably connected to the bracket. The device also includes a cover ring. Multiple through holes are provided on the cover ring, and bolts can pass through the through holes and connect to the second threaded holes.

[0005] Preferably, a fixing bolt is threaded onto one side of the bracket.

[0006] Preferably, the bottom of the water basin is provided with a first threaded hole, and the first threaded hole is connected to a valve located outside the water basin.

[0007] Compared with the prior art, the present invention has the following advantages: a water basin is rotatably connected to the bracket, the upper part of the water basin is open and a sealing ring is provided around the opening. After the sample is pressed tightly on the upper opening of the water basin with the cover ring, the water basin can be flipped so that the opening faces down. At this time, the water will come into contact with the sample for testing, which saves water. Attached Figure Description

[0011] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0012] Detailed implementation method: combined with Figure 1-2 As shown, a device for testing the permeability of magnesium oxide board includes a support 1 and a water basin 2. The upper part of the water basin 2 is open and a sealing ring 23 is provided around the opening. The opening is preferably rectangular. The magnesium oxide board sample 4 is a rectangular board. A basin rim 22 is provided on the outer side of the upper part of the water basin 2. Multiple second threaded holes 24 are provided on the basin rim 22. Rotating shafts extending in a horizontal direction are provided on both sides of the water basin 2. The rotating shafts are rotatably connected to the support 1, so that the water basin 2 can rotate around the rotating shafts. The device also includes a cover ring 5. The cover ring 5 is provided with multiple through holes 51. Bolts can pass through the through holes 51 and connect to the second threaded holes 24. During testing, the opening of the water basin 2 is facing upwards. Water is then added to the basin 2, and the sample 4 is placed over the opening of the basin 2, completely covering the sealing ring 23. The cover ring 5 is then placed on the sample 4, and a bolt is used to connect the cover ring 5 through the through hole 51 to the second threaded hole 24, pressing the sample 4 firmly onto the basin 2. The basin 2 is then rotated 180° so that its opening faces downwards, allowing water to contact the sample 4. The lower surface and sides of the sample 4 are then periodically observed for significant wetting or water droplets. After 24 hours, the basin 2 is rotated so that its opening faces upwards, the bolt is loosened, and the sample 4 is removed. Since continuous water spraying is not required, water is saved.

[0013] Furthermore, a fixing bolt 3 is threadedly connected to one side of the bracket 1. Tightening the fixing bolt 3 will allow it to rest against the side of the water basin 2, at which point the water basin 2 will not rotate on its own.

[0014] Furthermore, the bottom of the water basin 2 is provided with a first threaded hole 21, which is connected to a valve located outside the water basin 2. During testing (with the opening of the water basin 2 facing downwards), the valve can be opened to connect the inside of the water basin 2 with the outside, resulting in better testing results.

[0015] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
