The equipment requirements are as follows: >
1. The material of the manufacturing test box, supporting frame and spray device should be inertia for acid spray solutions to prevent the solution from contacting the material and the material Electrochemical corrosion.
2. acidity The test box should have a waste liquid collection system. >
3. The acid solution dripped from the test box wall, the top of the box, and the test parts cannot be reused . The test box should have an exhaust port to prevent the pressure in the box from rising.
4. The temperature of the test area in the test box should be kept at 35 ℃ ± 2 ℃, and the temperature should be continuously controlled during the test. Can not be used to control the temperature.
5. For the manufacture of acid solution storage box and the materials of the distributor (such as glass, hard rubber or plastic) should not react with the acid solution Essence The liquid storage box is continuously supplying acid solutions in the storage device that is usually located in the test area, and the height of the acid solution liquid surface in the storage device is moderately constant. The sprayer is connected to the storage device.
6. Enter the acid solution input Acid atmosphere The device in the test box, with air humidifier to make the input input The air is moist to reduce the jam of the nozzle. The sprayer should produce acidic water mist. The material of the nozzle and pipeline conveyor system should not react with acid solution. The test device should provide the required decentralized spray and settlement. >
7. There are at least 2 settlement liquid collectors. One is located near the test parts near the nozzle, and the other is located near the far away from the nozzle. If multiple nozzles are used, this principle is also applicable. The collector should not be blocked by the test piece, and it will not collect solutions dripped from the test parts or other sources.
8. The acid solution should be continuous and uniformly atomized, and its settlement rate should make each collector per hour at the level (10cm diameter) collected per hour per hour. 1ml ~ 3ml.
When conducting an acidic atmosphere, you should pay attention to the following items: >1. Strong acid danger. Spray solution is harmful to people and clothing. Acid atmospheric test operatorPrevention measures must be taken. If the anti -toxic mask and eye protection device should be used during the test, we can wear rubber gloves to treat the test parts.
2. Refer to the material security data manual or other similar information about the health hazards.
3. Do not enter the test box during the spray
. Before spraying into the test box, ventilation should be ventilated to reduce the concentration of harmful gases. 4. All waste liquids should be tested before discarding, and toxic waste shall be abandoned in accordance with relevant regulations or regulations.
acidity atmospheric test box has obtained a practical new invention patent. R u0026 D strictly in accordance with national military standards GJB150.28-2009. Can meet the test methods within the standard. A Tengsi is a high -tech enterprise that specializes in developing and producing environmental simulation test equipment. The production equipment and products have high cost performance and industrial standards in the industry. > The acidity atmospheric test box is made of GJB150.28_2009 acid atmospheric test standard system, an analog environmental reliability testtest box. This experiment is suitable for military equipment that may be stored or used in an acidic atmospheric area (such as an industrial area or a burning equipment). The purpose of this experiment is to determine the ability of the materials and surface coating to tolerate acid atmosphere. This test does not apply to the impact of the evaluation of hydrogen sulfide (because hydrogen sulfide is prone to oxidation in sulfur dioxide in the test) and cannot replace salt fog tests.
Features of acid atmosphere: > ◆ Use E-600 imported color touch screen Controller
◆ You can design different special design according to customer needs
◆ Electronic temperature sensor, high precision, low maintenance
◆ You can manually and automatically add water according to the different installation venues of the customer. It is convenient to use
◆ Use water -free heating method, fast temperature, energy saving, environmental protection, efficient
◆ It can be used for neutral salt fog test, copper acetate corrosion test, dry test◆ manually spray, manual fog, or automatic can also be automatically sprayed, or automatic can also be automatically sprayed. Periodic spray, continuous spray, timing spray
◆ You can realize salt fog and dry circulation test without moving products, convenient use
◆ Long -term stable operation
