Painted constant temperature and humidity chamber test box and stainless steel, which one would you choose?
The cold mixed steel plate is sprayed and treated, which is commonly known as the paint treatment of friends. In fact, the two are also somewhat different.
Powder spraying: electrostatic spraying of powder coatings, also known as spray coating. It uses a special electrostatic spray gun. After the paint is sent to the spray gun by means of compressed air, it is negatively charged near the corona discharge electrode of the electrostatic spray gun, thus generating electrostatic force and dipole force, and then driven by the pressure of the conveying gas. After the paint particles fly away from the spray gun, they fly along the power line to the positively charged workpiece and are arranged according to the distribution density of the surface power lines of the workpiece, so that the paint is firmly applied to the surface of the workpiece.

Baking paint: a special electrostatic spray gun is used, which uses the airflow from the compressed air to form a gas pressure difference with the tube connecting the paint cans, so that the paint liquid is sucked up from the paint can, and the air flow of the compressed air is brought to the nozzle to be blown into a fine mist. Evenly spray the surface of the workpiece.
From the above table, we can see that there is not much difference between the paint and the spray. Here we have a detailed analysis of the paint and stainless steel:
The stainless steel material is the frosted stainless steel outer box that everyone sees (of course, the inner box is mirror stainless steel, this is not to be argued). Both of these treatments will use constant temperature and humidity chambers and thermal shock test chambers. Which one is better? Let's analyze it in detail:
The constant temperature and humidity test box of the paint is generally made of A3 steel plate material. After spraying, the zui finally becomes the appearance of the paint. Generally, our appearance is baked in white, blue + white mixed. However, the bad point of Zui is that, with the influence of the external environment, the time is long, the outer box of the lacquer is easy to have a lot of points, and it will fall off. Zui is easy to rust at the point of falling off, zui is important. Some of the top of the paint can't be wiped off, it is very annoying. However, we still have to admit that the appearance of the sprayed constant temperature and humidity test chamber is very beautiful and durable. It will be very eye-catching in the early stage of use, and the pro will have a good experience.
The stainless steel constant temperature and humidity test chamber is also required by many customers. The outer box is made of stainless steel. After drawing, it is not only easy to rust, but also resistant to dirt and easy to clean. In terms of service life, the constant temperature and humidity test chamber of stainless steel is relatively longer than the constant temperature and humidity test chamber of paint. Of course, this is in appearance, their interior is actually exactly the same.
But what the friends Zui care about should be the price of the constant temperature and humidity test chamber of the paint and the stainless steel, which is more real?
In fact, two different outer boxes, for small models such as 80L, 150L, ​​the difference between the two is not big, parents can choose their favorite type according to their own needs, and large such as 800L, 1000L The difference between the two is relatively large, there is a 1000 or so, if the parents have reservations on the budget, they can choose the constant temperature and humidity box of the paint.
The constant temperature and humidity box of the paint and the stainless steel are good, and it’s a matter of opinion! !
