The Benefits of Using a Sand and Dust Test Chamber for Product Development

The sand and dust test chamber is suitable for the antifouling test of parts and materials such as welders, electronic equipment, electrical products, automobile lights, motorcycles, chemical plants, etc., and then check the shell sealing performance of the goods GB4208-93 shell protection level IP5X/IP6X antifouling test.
The key of the sand and dust test chamber is to simulate the damage of wind and sand temperature to hardware locks, auto parts, hydraulic seals and electric engineering surface lamps.

The sand and dust test chamber uses a powerful centrifugal fan to increase the sand and dust with a certain concentration, blows the surface of the test product with the necessary water flow, and then evaluates the ability to prevent the penetration of floating dust particles under the effect of dry sand or filled dust air. Prevent sand and gravel The ability to corrode or clog, and the ability to store and handle.

The principle of sand and dust test chamber:
1. The dust test chamber is equipped with vacuum packaging implementation components and electronic devices;
2. The main control board of the sand and dust test chamber adopts the PLC system to control the liquid crystal display, and selects the working hours of the information displayed in Chinese, etc.;

3. Fully automatic replacement of vibration and termination of vibration time;
4. Fully automatic replacement of the dust blowing centrifugal fan time;
5. Operable dust blowing centrifugal fan, dust vibration and total test time;

6. The control panel has the following random setting operation functions
(1) Dust blowing time (stop, blow): continuous, cycle time dust blowing random selection time setting
(2) Vibration time: Vibration and stop vibration time are automatically replaced, vibration time is 99 minutes, 59 seconds adjustable

(3) Prediction test time: test time: 99 minutes and 59 minutes at most
(4) Power supply: off-on-off-off-off
7. No fuse overload protection, overheating, load, leakage.

Structural advantages of sand and dust test chamber:
1. The dust test chamber is produced and processed with high-quality raw materials. The surface of the chamber and the door wall are made of high-quality thick steel plates. The surface electrostatic induction color electrostatic spraying solution has harmonious color matching, curved design scheme, and natural and smooth wire frame.
2. There is a detachable dust replacement device at the bottom of the sand and dust test chamber, which can easily replace the applied dust 100%.
3. The raw material of the inner tank is made of high-quality stainless steel plate. The design scheme is a closed indoor space, and the sealing test of the shell can be carried out according to the test piece. The indoor test frame and its accessories are made of stainless steel, and the design scheme is effective.
4. There is a big window on the tailgate and lighting equipment in the chamber. During the experiment, the experimental situation in the room can be clearly checked and the test piece can be seen clearly. The tailgate adopts two layers of rubber sealing strips, which are tightly sealed and convenient for power switch. In the chamber there is a very designed device to place the test product.
5. Install a unique sand and dust test chamber to ensure that the smoke does not stick to the inner wall of the chamber and solidify. The working time of the equipment is adjustable and can be replaced automatically.
6. Under the premise of meeting the national industry standards, the sand and dust test chamber has stable characteristics at all levels, which is basically more applicable and more conducive to operation. The sand and dust test chamber is easy to install and use, and most of them do not require daily maintenance.
7. The dust test chamber is equipped with a vertical dust circulation system for rotation, and talcum powder is used as smoke. The smoke is blown into the air supply mode channel through the centrifugal fan at the bottom of the tube, and then diffused evenly through the air outlet guide plate at the upper end of the device.
Smoke can be evenly floated in the test chamber by circulating air flow. According to the volume of the test chamber per cubic meter, the amount of talcum powder used is 2kg, and the application frequency shall not exceed 20 times. Stainless steel plate centrifugal impeller drives smoke and dust. Air vent deflector.
8. Laboratories that can conduct sand and dust tests at this stage. There are natural environment reliability and electromagnetic compatibility test management centers, aerospace natural environment reliability tests and testing institutions, etc.

Negative effects of dust used in dust experiments on processing, product quality, economic benefits, natural environment and biodiversity. impact on economic performance. The key is to reduce product quality, reduce product rate, and reduce product quotation;

The service life of professional dust test chambers is gradually reduced, which promotes solid capital investment, gradually increases production costs, and weakens competitiveness; post patients lack professional ability, medical expenses, medical expenses, and medical welfare expenses caused by smoke and dust;

Working in high-concentration dust workplaces, customers are worried about their physical and mental health, often losing their professional capabilities, speeding up the cycle time of the company’s professional and technical personnel, and requiring large investment in training costs, which also leads to unstable output rates.

The hazards and kinetic energy of smoke and dust are so great that if we cannot remove them, then we can only start with our own prevention. At the natural environment level of survival, food, clothing, housing and transportation, we use various methods to protect smoke and dust, and minimize the damage to the body and the impact on survival, food, clothing, housing and transportation.

At the level of industrial production, we can rely on professional dust test chambers in the natural environment of smoke and dust to carry out anti-fouling and dust-proof tests of commodities, improve product quality and application level, and improve the economic benefits of economic development.
