With the rapid development of modern industrial technology, the application fields of electroplating products are becoming wider and wider, and the environmental conditions they are experiencing are becoming more and more complex and diverse. Only by reasonably specifying the environmental conditions of the product and choosing the environmental protection measures of the product correctly can the product be protected from damage during storage and transportation, and be safe and reliable during use. Therefore, it is necessary to ensure the high quality of materials or products by artificially simulating environmental tests. The artificial simulated environmental test is a scientific summary of the actual environmental impact, and has the characteristics of typicalization, standardization, convenient use, and easy comparison. The diversification of environmental conditions and the importance of environmental testing also put forward stricter requirements for environmental testing equipment. The sulfur dioxide gas filter device designed by our company can quickly and effectively filter the residual sulfur dioxide gas in the box. The gas first enters the calcium hydroxide to produce a neutralization reaction, and then enters the activated carbon filter. Will cause pollution to the atmosphere, easy to operate and practical. The sulfur dioxide test chamber can be kept constant at 40 ° C in the test work space. Introduce a certain amount of sulfur dioxide gas into the tank of a specified volume to conduct a corrosion test on the material or product under the condition of constant concentration, temperature and relative humidity. The material used to manufacture this equipment is a corrosion-resistant imported PVC plastic sheet that does not react with sulfur dioxide, does not absorb sulfur dioxide, and does not affect the test results. In the design work of this equipment, the internal and external pressures are balanced, and the mixed gas flows uniformly in the box. And the design takes into account the top of the device, the inner wall and other parts will produce condensate, so the top of the box is designed to have an optimal angle of 120 degrees. During the test of the device, the condensate will not drip onto the sample and affect the test results . dog chew toys,dog puzzle toys,dog toys for large dogs,indestructible dog toys,dog toys for small dogs Ningbo XISXI E-commerce Co., Ltd , https://www.petspetsdoggze.com
