2016 Sulfur dioxide test chamber under saturated state can be customized

With the rapid development of modern industrial technology, the application fields of electroplating products are becoming increasingly broad, and the environmental conditions they undergo are becoming more and more complex and diverse. Only by reasonably specifying the environmental conditions of the product and correctly selecting the environmental protection measures for the product can the product be protected from damage during storage and transportation and be safe and reliable during use. Therefore, artificial simulated environmental testing of materials or products is an indispensable and important link to ensure their high quality. Artificial simulated environmental tests are scientific summaries of actual environmental impacts and have the characteristics of typification, standardization, ease of use, and ease of comparison. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
The sulfur dioxide test equipment uses sulfur dioxide gas to accelerate corrosion of materials or products under a certain temperature and relative humidity environment to reproduce the degree of damage suffered by the material or product within a certain time range. The equipment can be used to assess the resistance to sulfur dioxide corrosion of materials and their protective layers and to compare the process quality of similar protective layers. It can also be used to assess the resistance to sulfur dioxide corrosion of certain products.
The equipment can maintain a constant temperature in the test working space. Corrosion tests are conducted on materials or products by introducing a certain amount of sulfur dioxide gas into a box with a specified volume to keep the concentration, temperature, and relative humidity constant.
The materials used to manufacture this equipment are corrosion-resistant imported plastic sheets that do not react with sulfur dioxide, do not absorb sulfur dioxide, and do not affect the test results. When this equipment is designed to work, the internal and external pressure-balanced mixed gas flows at a constant speed inside the box. Moreover, the design takes into consideration that condensation water will be generated on the top inner wall of the equipment and other parts, so the top of the box is designed so that condensation water will not drip onto the sample during the test and affect the test results.
This sulfur dioxide corrosion test chamber has a beautiful appearance, reasonable structure, smooth lines, and natural flow. The outer shell of the box is made of imported plastic sheets, with a smooth and bright appearance, no scratches, corrosion resistance, easy cleaning, and no leakage. The inner tank is made of the same plastic sheet that is temperature resistant. Various auxiliary accessories and facilities are also designed with corrosion-resistant structures.
The oversized door is made of tempered glass and has a corrosion-resistant silicone rubber seal that is also corrosion-resistant, easy to clean, and leak-free. During the test, the indoor test conditions can be clearly observed from the outside without affecting the test results. The door and box body are strongly sealed with corrosion-resistant silicone rubber to prevent sulfur dioxide (hydrogen sulfide) from overflowing, which may affect test results, corrode other equipment in the room, and even cause harm to test operators.
The box heats up quickly and the temperature and humidity are evenly distributed. The sample rack is designed according to national standards and can also be hooked. After the sulfur dioxide gas comes out of the cylinder, it is decompressed and then measured to the required volume through a special sulfur dioxide metering barrel. Then it enters the split pipe at the bottom of the box and mixes evenly with the humid air in the box to gradually corrode the sample.
The equipment control system is designed on the right side of the box for easy operation. The specially designed sulfur dioxide gas filtering device can quickly and effectively filter the residual sulfur dioxide (hydrogen sulfide) gas in the box after the test. The remaining gas will not cause pollution to the atmosphere. It is easy to operate

This sulfur dioxide corrosion test chamber has a beautiful appearance, reasonable structure, smooth lines, and natural flow. The outer shell of the box is made of imported plastic sheets, with a smooth and bright appearance, no scratches, corrosion resistance, easy cleaning, and no leakage. Various auxiliary accessories and facilities are also designed with corrosion-resistant structures.
The oversized door is made of tempered glass and has a corrosion-resistant silicone rubber seal that is also corrosion-resistant, easy to clean, and leak-free. During the test, the indoor test conditions can be clearly observed from the outside without affecting the test results. And ensure that sulfur dioxide gas will not leak, which will affect the test results, corrode other equipment in the room, and even cause harm to test operators.
The equipment is completely designed and produced with reference to the sulfur dioxide test chamber imported from Germany. The temperature control of the equipment adopts imported temperature instruments. During the test, the equipment adds 1 liter of water sample inside the box volume and places it on a special sample rack. After starting up, liters of sulfur dioxide gas is introduced and heated for an hour. The equipment automatically stops heating and begins to discharge waste gas outside. The waste gas is filtered by special materials and then discharged outside. This is followed by an exposure period of several hours. The equipment's sulfur dioxide inlet gas passes through a special sulfur dioxide measuring barrel to measure the required amount, and then the gas is introduced into the box for testing. The sulfur dioxide gas is decompressed by a special pressure reducing valve for sulfur dioxide. After the gas transmission valve is opened, the gas enters the equipment through a corrosion-resistant polytetrafluoroethylene pipe. The special sulfur dioxide metering cylinder measures the liter/liter of gas, and then the measured gas is input into the box by opening another valve. After the body is properly guided and spreads evenly, it is simple to test the product. The measurement range is accurate after calibration.
The equipment control system is designed on the right side of the box for easy operation. The specially designed sulfur dioxide gas filtering device can quickly and effectively filter the remaining sulfur dioxide gas in the box into the calcium hydroxide to produce a neutralization reaction and then into the activated carbon filter. After adsorption, the remaining gas is discharged without causing pollution to the atmosphere. The operation is convenient and practical. . The box is heated using a titanium metal heating tube. The water bottom tank is heated liter/liter. The temperature rises quickly. The temperature and humidity distribution are uniform and the humidity is close to %. Specially designed sample holder.
