Description

Technical Field

[0001] This utility model belongs to the field of building material testing technology, and in particular relates to an experimental device for detecting resistance to efflorescence. Background Technology

[0002] During coating projects, primers for interior and exterior walls are applied directly to the substrate (cement mortar, putty, or other base materials) of the building. This seals the substrate or strengthens it through penetration, preventing the entry of salts and alkalis into the coating layer. The primer's ability to prevent and resist the precipitation and penetration of salts and alkalis from the substrate into the coating layer is its most basic performance characteristic and a key indicator of product quality. Testing equipment for resistance to salt and alkali efflorescence presents several inconveniences in practical operation and use, such as the inability to level the sample plate, difficulty in controlling the water level, and the risk of contamination of the test surface during liquid addition and handling.

[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] like Figure 1-10As shown, an experimental apparatus for detecting resistance to efflorescence includes a housing 101, a pad 107, a partition 108, a cover 102, a storage tank 104, a liquid level sensor, and a pump 106. The side walls of the housing 101 are transparent to facilitate observation of the interior. The partition 108 has multiple through slots. The pad 107 is located inside the housing 101, with the partition 108 resting on it. The cover 102 covers the housing 101. The liquid level sensor is located inside the housing 101 and is electrically connected to the pump 106. The storage tank 104 is connected to the housing 101 via a connecting pipe 105, and the pump 106 is mounted on the connecting pipe 105. When testing the sample plate 200, the partition 108 is placed on the pad 107, and then the sample plate 200 is placed on the... On the partition 108, the alkali solution in the storage tank 104 is pumped into the box 101 by the pump body 106. The liquid level is submerged to half the height of the sample plate 200 through the through groove on the partition 108. The liquid level sensor monitors the liquid level. If the liquid level in the box 101 is too high, the pump body 106 extracts the alkali solution in the box 101 and stores it in the storage tank 104. If the liquid level in the box 101 is too low, the pump body 106 pumps the alkali solution in the storage tank 104 into the box 101, keeping the liquid level in the box 101 at a stable value. When the sample plate 200 is taken out and placed, the pump body 106 extracts the alkali solution in the box 101, causing the liquid level in the box 101 to drop below the partition 108, thus avoiding contamination of the alkali solution during sampling and placement.

[0038] The cover plate 102 has a triangular structure. A flap 103 is provided on the cover plate 102. The flap 103 forms the top surface of the cover plate 102.
