AI Technical Summary

Technical Problem

When testing the reflection and stain resistance of tunnel inner wall coatings, the prior art is not accurate enough to effectively obtain the specific contamination of the coating.

Method used

A tunnel coating reflective and stain-resistant performance testing device is designed, including a test box, a reflective testing mechanism, a stain-making mechanism and a stain-scraping mechanism. By intermittently testing the reflective performance, continuously introducing impurities such as dust, scraping off pollutants and weighing them after stopping, to obtain the specific stain resistance of the paint.

Benefits of technology

The device uses scientific testing methods to replace traditional naked eye observation, which significantly improves the accuracy of the test and can more accurately evaluate the reflective and stain resistance of the paint.

Abstract

The invention belongs to the technical field of coating performance testing, and particularly relates to a tunnel coating light reflection and stain resistance testing device and method.The tunnel coating light reflection and stain resistance testing device comprises a testing box, a light reflection testing mechanism, a stain making mechanism and a stain scraping mechanism, and the testing box comprises a box body, a bottom plate located at the bottom of the box body and a box cover located at the top of the box body; the light reflection testing mechanism is installed on the bottom plate, and when the light reflection testing mechanism works, the light reflection performance of the testing plate body with the bottom coated with the testing coating on the box cover is intermittently tested; the pollution making mechanism is located on one side of the box body, and when the light reflection testing mechanism works, the pollution making mechanism is driven to work, and impurities such as dust are continuously guided into the box body; the dirt scraping mechanism is installed on the box cover and corresponds to the bottom of the test plate body, when the dirt making mechanism stops working, the dirt scraping mechanism is automatically driven to work, dust and other impurities attached to the bottom of the test plate body are scraped off and reserved, and the problem that in the test process, the test condition is observed through naked eyes, and consequently the test is not accurate enough is solved.
