Dust Test Chamber Mainly used in low-voltage electrical appliances, motor, instruments, instruments, electronic products, dust simulation testing of lights, is to evaluate mobile phones, electrical products and other products Sealing properties in dust, automotive, motorcycle components, seals, etc., store, storage, transportation in the dusting environment.
The fan pushes a certain concentration of sand through the surface of the test sample at a certain flow rate, and the test is exposed. The ability to prevent dust microparticles permeate effects under dry sand or dust-filled atmosphere, defending the ability of gravel or obstruction effect and whether it can be stored and operated.
Test dust can be recycled, and the entire airway is made of imported advanced stainless steel plates, and the bottom of the wind is connected to the tapered hopper interface. The vent is directly connected to the air, and then the top proliferation port of the studio is connected to the studio body in the position of .
The basic principle of dust test chamber is mentioned in the standard. In addition, the powder uncontrolled pump in the closed test chamber can be used instead of other methods that can suspend talcum flour. Talca powder is filtered by metal square, 50 mu; m, m, sieve size is 75 mu; m, talc powder is used for each cubic meter test chamber 2 kg, and the number of use cannot exceed 20 times. Moreover, the choice of talc powder should also meet the provisions of human health and safety.
Test dust test in dust test chamber not only has talc powder, but also mentioned in other standards. Acid cement, olivine or smoke, etc., and its dust is also available in continuous and cycle.
