Description

TECHNICAL FIELD

[0001] The utility model relates to building coating construction, light anticorrosion construction technical field more specifically relates to a kind of quick detection test film. BACKGROUND

[0002] In the construction field, especially the workpiece with steel metal as base material, such as color steel tile renovation, steel structure engineering, mechanical equipment and the like, the anticorrosive effect of anticorrosive coating needs to be detected. These workpieces are easily corroded during use due to long-term exposure to the natural environment, affecting their service life and safety. Therefore, quickly detecting the anticorrosive effect of the anticorrosive coating is crucial to ensuring the quality of the project and prolonging the service life.

[0003] The existing detection method is usually visual detection, which observes the appearance of the coating with the naked eye to check for obvious defects such as bubbles, cracks, wrinkles, etc. This method is simple, but it cannot accurately assess the water resistance and corrosion resistance of the coating. There is also a method of using a xenon lamp aging test chamber to simulate the light, temperature and humidity conditions in the natural environment to accelerate the aging process of the coating and assess its weather resistance. This method requires professional test equipment, has a complex structure and a long test period.

[0004] Therefore, how to provide a detection test film with a simple structure that can quickly detect the water resistance and corrosion resistance of the coating is a problem that needs to be solved by those skilled in the art. UTILITY MODEL CONTENT

The film layer is located on the outside, and the heat-absorbing coating layer, the resin layer and the non-woven fabric layer are sequentially pressed and formed on the inside of the film layer.

[0008] Through the above technical solutions, the quick detection test film provided by the utility model forms a whole detection film through the design of the multi-layer structure. The film layer provides light transmission, the heat-absorbing coating layer provides heat-absorbing function, the resin layer provides water absorption, and the non-woven fabric layer provides overall structural support and water absorption. Each layer is pressed and formed to ensure the stability and reliability of the structure. The use of the detection film can quickly detect the water resistance and corrosion resistance of the anticorrosive coating. The utility model solves the technical problem that the existing visual detection method cannot accurately assess the corrosion resistance of the coating in the prior art, improves the detection accuracy, and the structure is simple and easy to carry.

[0009] Preferably, in the above-mentioned rapid detection test film, the side edge of the non-woven fabric layer away from the resin layer has an adhesive layer. The adhesive layer ensures that the detection film can be firmly fixed on the surface of the detected object, preventing displacement or falling off during the detection process, and improving the stability and reliability of the detection.

[0010] Preferably, in the above-mentioned rapid detection test film, the adhesive layer is double-sided adhesive. Double-sided adhesive has good adhesion, can provide stable adhesion on the surface of different materials, ensure the stability and reliability of the detection film in various environments, and is convenient to operate and use.

[0011] Preferably, in the above-mentioned rapid detection test film, the film layer is a light-transmitting film; the material of the film layer is polyethylene or polypropylene, and the thickness is 0.06-0.1mm. The light-transmitting film can conveniently observe the changes of the coating, such as flash rust, discoloration, bubbles, wrinkles, etc., and the polyethylene or polypropylene material has good light transmission and chemical stability, ensuring the transparency and durability of the detection film during use.

[0012] Preferably, in the above-mentioned rapid detection test film, the thickness of the heat-absorbing coating layer is 40-60um. The heat-absorbing coating can absorb the heat of sunlight, increase the temperature of the detection film, and accelerate the appearance of the anticorrosion effect. The thickness of 40-60um ensures that the heat-absorbing coating layer has sufficient heat-absorbing capacity and uniformity, improving the sensitivity and accuracy of the detection.

[0013] Preferably, in the above-mentioned rapid detection test film, the resin layer is a water-absorbing resin, and the thickness of the resin layer is 0.8mm-1mm. The water-absorbing resin can absorb a large amount of water, provide a high-humidity environment, and accelerate the appearance of the anticorrosion effect. The thickness of 0.8mm-1mm ensures that the resin layer has sufficient water-absorbing capacity and water retention, improving the sensitivity and accuracy of the detection.

[0014] Preferably, in the above-mentioned rapid detection test film, the resin layer has a pH adjuster inside. The pH adjuster can adjust and stabilize the pH of the resin layer, ensure that the detection film maintains a stable chemical environment during use, improve the accuracy and reliability of the detection, and prevent detection errors caused by pH changes.

[0015] Preferably, in the above-mentioned rapid detection test film, the material of the non-woven fabric is polyester fiber or viscose fiber, and the thickness is 0.08-0.2mm. The non-woven fabric layer of polyester fiber or viscose fiber provides mechanical support and water absorption, ensuring the close fit of the detection film with the surface of the detected object. The thickness of 0.08-0.2mm ensures that the non-woven fabric layer has sufficient strength and water absorption, improving the stability and reliability of the detection.
