Why doesn't the sand and dust test chamber use a real sand test?

The sand and dust test chamber is to simulate the weather of the wind and sand in the natural environment, mainly to test the product's resistance to wind and sand, and corrosion resistance and other performance
.

If it is simulating the condition of wind and sand in nature, then why not use real sand? The following has Aipei Technology Xiaobian to answer for you! The sand in the sand dust test box that simulates sand dust is not really sand in our natural life, and it is replaced by
* stone powder.

The first reason is that there are many kinds of sand in life, and there are many kinds of sand in life, and if you really use the sand in life, you can't fully represent all
.

The sand in nature is a very heavy one, and the sand is tested in the test chamber, and the circulation fan in the sand and dust test chamber and the automatic shock device are very difficult to blow the sand into the upper part of the
studio.

Since the sand is a very irregular thing, it is not easy to enter the square hole in the filter screen of the
sand dust test chamber.

At the same time, it is also easy to clog the
screen.

The reason why we use * stone powder for testing, * stone powder is a very small weight, and sand is also very similar to the thing, * stone powder is very delicate, when the test is easy to clean
.

When we conduct dust tests, the sand and dust test chambers usually do not use the real sand soil in natural life for testing
.

Instead, use * stone powder instead
.

But the effect achieved is the same
