Beijing's latest and most comprehensive range of high-precision salt spray chamber products

The salt spray test is a test that artificially simulates a salt spray environment. It has significant advantages compared with exposure tests under atmospheric conditions: the corrosive environment can be controlled and the environment is reproducible. The test time is significantly shortened, saving a lot of manpower, financial and material resources. Its development and practicality have quickly developed from the initial simple neutral salt spray test to: acetate salt spray test, copper salt accelerated acetate salt spray test and alternating salt spray test and other forms. Our country has adopted the salt spray test as a national standard and has made detailed regulations.
Salt spray corrosion test equipment uses salt-containing solutions or acidic salt-containing solutions to accelerate corrosion of materials or products under a certain temperature and relative humidity environment to reproduce the damage suffered by materials or products within a certain time range. degree. The equipment can be used to assess the salt spray corrosion resistance of materials and their protective layers and to compare the process quality of similar protective layers. It can also be used to assess the salt spray corrosion resistance of certain products.
The equipment can reach any temperature point from normal temperature to ℃ in the test working space and maintain it constant. Conduct a salt spray corrosion test on materials or products when the temperature and relative humidity in a box with a specified volume are constant. The materials used to manufacture this equipment are imported corrosion-resistant plastic sheets that do not react with salt-containing solutions or acidic salt-containing solutions and will not affect the test results. During the design of this equipment, the internal and external pressures are balanced and the salt spray settles freely inside the box and can be adjusted to the range specified by national standards.
The structural design of the test chamber is advanced and reasonable, and the supporting products and functional components are at the domestic advanced level and can adapt to long-term, stable, safe and reliable production needs. It can meet the processing and production requirements of users for the above purposes and is easy to use, operate and maintain. It has a long service life and beautiful appearance. It has a good user interface, making the user's operation and monitoring more simple and intuitive.
The main components of the equipment are selected from high-quality products from well-known domestic brand manufacturers to ensure the quality and performance of the entire machine. The equipment has perfect performance, simple functions and easy operation.

3. Test box structure
. The inner and outer casings are made of imported plastic plates, which are softened and then cooled at high temperature through a special mold to form the joint between the plates. The seams are planed and milled into right angles, and then filled with a high-temperature welding nozzle to melt plastic wire. After cooling, the welds become stronger. The seams of the entire box are smooth and smooth, and the box structure is compact and bright in appearance.
. The spray method of this equipment is to use a built-in glass crystal-free nozzle placed in a circular plastic tube. The spray is guided through the tower tube and then dispersed into the test chamber through a conical disperser. The mist spreads evenly and settles freely in the test chamber. inside the box. The fogging and fogging aspects are exactly the same on all sides. The number of test pieces placed is large.
. The brine before spraying is injected into the preheating tank through the brine storage tank (the capacity on the left side of the equipment can be designed according to customer requirements) for preheating and then introduced into the spray tower. The temperature fluctuation of the studio after constant temperature is smaller. The storage box barrel is equipped with a hidden water level gauge, which is easy to clean and not easy to break.
. The temperature inside this series of test chambers adopts the bottom water heating method to make the temperature of the chamber more uniform and stable.
. The heating element uses a titanium heating tube that is salt-resistant, corrosion-resistant and has a long service life.
. The box cover adopts imported transparent board, which is convenient for opening and closing. The water-sealed structure ensures that salt spray does not escape.
. The box cover adopts an included angle to ensure that condensed water does not drip on the test piece, and the box is equipped with a pressure balance hole and a condensate discharge hole.
. Automatic mist exhaust function.
. The sample rack structure is reasonably designed, the shape groove + bar rod angle and angle design are convenient for angle adjustment. The large load-bearing capacity is easy to place the sample.
. Comes with double over-temperature protection and low water level warning to ensure safe use.
. The saturated air barrel uses Henry's law to heat and provide the required humidity for the test chamber.
