1. The water tester is used to test the glue effect of the glue strip. Air-tightness testing equipment is used to test whether there is water leakage, belt wear and other problems at the glued position in the form of hydraulic pressure. Generally test 3PSI for two minutes without water leakage, the bonding effect is considered qualified.   2. The test needs to be done step by step, first try IPSI/30 seconds, and slowly progress to 3PSI/2 minutes. Abnormal results caused by sudden pressure can be avoided.   3. Adjust the tightness of the "iron ring" of the water testing machine. If it is too tight, it will damage the rubber layer and film of the fabric, and the air tightness test will even leave marks on the fabric; if it is too loose, the water pressure will not meet the standard and cause not getting normal results   4. The glue layer and film of some fabrics are easily damaged, and the "iron ring" of the air tightness tester needs to add a layer of soft fabric. Prevent the "iron ring" from damaging the glue layer and film of the fabric.   5. The water used by the water testing machine must be clean and free of impurities, so as to avoid debris from clogging the pipes, and the waterproof tester will cause inaccurate data on the pressure gauge. The pipes and water container of the water tester need to be cleaned regularly.   6. When testing the water test machine, the airtight leak tester may have fabrics that are easy to absorb water, which should be handled carefully to prevent the fabrics from absorbing moisture and being difficult to dry, which will affect the subsequent processing and final packaging.    Choose D & S Automatic, we will provide you with the best service.

The full name of the salt spray test machine is a salt spray test machine, which is mainly used to test the corrosion resistance of samples. At present, it is widely used in aerospace industry, automotive electronics, electronic electrician, mobile phone digital, plastic products, metal materials and other industries to test its corrosion resistance. It is also to simulate extreme conditions under natural conditions or working conditions to understand the properties of each sample. performance temperature. The working principle of the salt spray testing machine is relatively simple. It mainly uses corrosive gas and liquid to spray the sample. By spraying the corrosive gas and liquid until the corrosion of the sample occurs, the longer the time is as the corrosion resistance of the sample, the It means that the corrosion resistance of the sample is better. The working principle of the salt spray test is to compress the corrosive solution into an air spray, and then wrap the spray on all sides of the sample as much as possible. This test can be carried out continuously or cyclically until the expected corrosion phenomenon appears on the sample. The corrosion time is then recorded to indicate the corrosion resistance of the sample. Generally, the corrosion solution in the salt spray testing machine is mainly 5% sodium chloride solution or adding 0.26 grams of copper chloride per liter to the sodium chloride solution as a salt spray corrosion solution. In addition, the salt spray testing machine can independently adjust the settlement and spraying volume of salt spray to ensure constant test temperature, convenient operation and stable test environment. Therefore, it is often used to test the corrosion resistance of daily necessities or industrial products. Choose our D&S machines to provide you with the best salt spray testing machines.
