Magnet - we have a deep memory when we were young. It feels like a very magical thing. Now there are two types of hollow built-in shutter glass! It is divided into magnetic control and electric (electric control)

I won’t talk about it for the time being. I’ll mainly talk about the magnetic control part). As the name suggests, the  magnetic control hollow built-in shutter glass is mainly controlled by the force generated by the positive and negative poles of the magnet.

Usually, what we know about magnets is objects that repel and attract each other. The magnet is composed of iron, aluminum, nickel, cobalt, etc. it has magnetic distance, and its internal structure is arranged in the same direction, with one north pole (N pole) and one south pole (S pole). Now, the N-pole surface of the magnet used by Ginghongxin is scribed, and the S-pole surface is not scribed, so as to distinguish. Some hollow built-in louver glasses are demagnetized because the magnets inside and outside the glass are installed in the wrong direction, resulting in insufficient magnetic force.

The unit of magnetic induction intensity is Tesla, abbreviated as T. magnets are divided into permanent magnets and non permanent magnets. Permanent magnet is a natural product that can maintain magnetism for a long time and is not easy to lose magnetism. The strong magnet used by Ginghongxin is permanent magnet. The magnetism of each batch of goods is tested. If it is unqualified, it will not be put into storage.

Others will have questions. Since your built-in shutter products are equipped with magnets, will the magnets have radiation? In fact, the earth is a big magnet. Human beings are affected by the magnetic field all the time. The human body has different degrees of micro magnetic field. A weak and stable magnetic field is good for the human body. Magnets only produce a constant magnetic field, not radiation, but magnetic field.

The high-intensity magnet is formed by sintering. Because the material contains aluminum and iron, the surface is easy to rust and needs some protective electroplating treatment. The general thickness is 0.015-0.03. Of course, try not to contact with a large amount of water substances. If you wipe, you can use alcohol and so on. If the electroplating surface is damaged after long-term or frequent contact with water substances, the  magnetic control will rust and affect the service performance.

The magnets used by Ginghongxin are all produced by domestic listed companies. Before receiving and during use, they must be tested with a flux detector, and the surface plating will also be tested with oxidation treatment. Please feel free to use.
