Description

Technical Field

[0001] This utility model belongs to the field of building engineering material testing technology, specifically relating to a structure of a rust inhibitor coating experimental device, which is particularly suitable for testing the uniformity of rust inhibitor coating and evaluating the anti-corrosion effect on different substrates. Background Technology

[0002] Reinforced concrete is one of the main building materials, and corrosion of the reinforcing steel in reinforced concrete structures can lead to durability failure. Corrosion inhibitors for reinforcing steel are chemical substances added to concrete or applied to the concrete surface that can prevent or slow down the corrosion of the reinforcing steel.

[0003] As an important protective measure, the coating process and coating quality (such as uniformity and thickness) of rust inhibitors directly affect the protective effect. Therefore, it is crucial to conduct accurate, efficient and repeatable evaluation of the coating performance of rust inhibitors in a laboratory environment. At present, existing rust inhibitor coating experiments mainly rely on two methods: (1) manual spraying and measurement, which has significant drawbacks: the uniformity of spraying is highly dependent on the operator's skill level and has poor repeatability; the spraying position and distance are difficult to control precisely; (2) using large-scale, general-purpose industrial spraying equipment: although such equipment has a certain degree of automation, it is usually large in size, complex in structure and expensive, making it difficult to meet the small-scale and diversified experimental needs of the laboratory. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rust inhibitor coating test device structure that is compact, simple to operate, convenient to use and maintain, and can adapt to the coating process of various specimens of different shapes and sizes, thus significantly improving the efficiency of rust inhibitor coating test.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A rust inhibitor coating experimental device structure mainly includes: a clamping unit, a spraying unit, and a detection unit. The clamping unit includes a base plate 6, a rotating platform 9 disposed in the middle of the base plate 6, and a clamping assembly disposed on the rotating platform 9. The clamping assembly is used to clamp the steel bar specimen to be coated.

The detection unit includes a laser thickness gauge 3 slidably mounted on the linear sliding guide rail 4 and a weighing device 10 disposed on the base plate. A detachable synchronous connection is provided between the laser thickness gauge 3 and the adjustable nozzle 2.
