Proposal for Color Stone Metal Tile

Release time: 2022-11-04

　　 The weather resistance test of colored stone metal tile surface is to simulate the repeated action of sudden rainstorm and winter and summer temperature after high temperature exposure in summer, and to carry out accelerated weather aging test on colored stone metal tile surface, which is a more important test item to test and evaluate the quality of tile surface system. The weather resistance test has a good correlation with the engineering practice, and can better reflect the actual weather resistance of the project. The weather resistance test requires that the sample shall be free of hollowing, falling off and cracking after 20 cycles of high temperature (70 ℃)-rainfall (15 ℃) and 20 cycles of heating (50 ℃)-freezing (-20 ℃).

　　 High frequency: For a manufacturer that pays attention to technology and testing, for the development of each product, the adjustment of each formula, and the replacement of each raw material, in addition to strict quantitative single index testing and analysis, the product should also be tested for physical and qualitative construction performance and comprehensive performance. Color stone metal tile high efficiency: shopping malls such as the battlefield, enterprises in order to meet the needs of the market, the effectiveness of testing is often very high, and the vast majority of testing institutions due to the system, the services provided are often difficult to meet the requirements of enterprise testing.


　　Colored stone metal tileSunlight simulation: Xenon arc radiation is a commonly used aging test method in China, while xenon arc radiation and ultraviolet aging test are widely used abroad, and their principles are completely different. The xenon lamp room simulates the full spectrum of the sun, including ultraviolet, visible and infrared light, with the purpose of simulating sunlight. Color stone metal tile UV aging test is not trying to simulate the sun's rays, but to simulate its destructive effect. This is based on the principle that durable materials exposed to the outdoors for a long time are more damaged by aging caused by short-wave ultraviolet light.


　　 After comprehensive cost-effective analysis: the use of ultraviolet ordinary baking lamps to simulate direct sunlight to ensure that sunlight damage and temperature damage are close to the actual situation. Temperature simulation: According to the standard requirements, the temperature control range of the weather resistance laboratory should reach -25 ℃ ~ 30 ℃. However, due to the high cost of refrigeration equipment, according to the temperature range of cold winter and hot summer areas, the simulation is temporarily carried out at 0 ℃ ~ 70 ℃. The method is as follows: 1:0 ℃ ~ 10 ℃ range: the laboratory is mainly cooled with ice, and the experimental tile is sprayed with ice-water mixture. 10 ℃ ~ 50 ℃ range: The temperature control box is mainly used to adjust the temperature of the laboratory, and its adjustment range is from room temperature to 50 ℃. At the same time, auxiliary electric heating is used to heat the laboratory.

　　 3:50 ℃ ~ 70 ℃ range: in summer, the sunshine time is long, the solar radiation intensity is large, usually the air temperature on the outer surface of the horizontal roof is 60~70 ℃, the comprehensive temperature of the west wall is 50~60 ℃, and the comprehensive temperature of the east wall is 45~50 ℃. according to the requirements, we use 5-10 baking lamps and 2 groups of simulated sunlight ultraviolet lamps for baking to ensure that the surface temperature of the experimental wall reaches the ideal temperature, and ensure sufficient irradiation time.
