Background
Cockroaches are common sanitary pests, and their abuse has brought about a great influence on the normal lives of people. Because the cockroaches have strong viability and reproductive capacity, the common killing means can hardly remove the cockroaches completely. Cockroaches are characterized by omnivorous nature and are often moved in places such as garbage dumps, toilets, and the like. Through detection, cockroaches caught in hospitals and families of residents almost carry pathogenic bacteria. Consequently, the activity of cockroaches presents a potentially serious health hazard to residents. The ceramic tile is a building material which is most widely adopted in modern home and commercial decoration, and the ceramic tile with the cockroach-repelling function is prepared by taking the ceramic tile as a carrier of the cockroach-repelling and cockroach-preventing functional agent, so that the cockroach-repelling effect can be improved to the greatest extent, the ceramic tile has a positive effect on cockroach-repelling and cockroach-preventing, and the ceramic tile is beneficial to improving the sanitation of home and office environments and reducing disease spread.
The invention patent of China (CN 112525756A) discloses a method for testing the cockroach prevention effect of a ceramic tile, which is characterized in that two ceramic tile samples with cockroach feed on the surfaces are placed in a national standard square box, the reduction condition of the cockroach feed on the surface of the ceramic tile to be tested in a certain time period is tested, and the more the feed is left, the better the pesticide effect is. However, this method generally takes 7 days or more to obtain the test result, and is not sufficient for rapid detection.
At present, a quick testing device and a corresponding testing method for the cockroach prevention performance of the ceramic tile are not available. The existing cockroach-preventing drug effect test method is long in time consumption, and the drug effect test result fluctuates, so that the method is not beneficial to quickly and accurately evaluating the cockroach-preventing drug effect of the ceramic tile.
