With the word "blackboard" we in most cases associate school time. Chalk inscriptions on the surface of an old board, the need to rinse a rag or washcloth well so that no streaks remain after it. Now the boards are used not only in school classes. Offices, premises for trainings, seminars, various meeting rooms - all of them require a surface on which one can record this or that information. That is why the production of boards has gone further. In an effort to make a more durable and convenient product, manufacturing companies have created magnetic whiteboards. On their surface, the writing element is not chalk, but a marker. Writing is erased using a special washcloth, which does not need to be rinsed in the washstand.
Much depends on the production method of magnetic whiteboard , including its quality and service life. This is how the surfaces created with the enameling method are distinguished. White enamel is applied to the base. This piece is placed in an oven and exposed to high temperatures. The result is a high quality whiteboard. Its weak point is the instability to strong impacts with a heavy object. It is also not advised to drop it, as the enamel can chip off, ruining the writing surface.
1) "If you follow the rules of use, the enamel whiteboard will serve you for a very long time."
The fact is that the hardened enamel does not have microcracks in its structure, where the marker paint can clog. This is why the enamelled whiteboard will look like new after five years.
Another type of surface treatment is painting. A layer of special paint is applied to the board after pre-treatment. This is usually used in refrigerators.
2) "Painted boards are virtually immune to physical damage."
But over time, their surface fades, turning from glossy to matte, and also loses its whiteness. Such metamorphoses are explained very simply. The paint has micropores. When writing something with a marker, paint particles fall on the surface and clog in these pores. Therefore, a painted board can change its whiteness over time.
There are also unscrupulous manufacturers and fakes. They paint the boards with cheap paint. Visually, you will not see the difference, but in the process of use it will soon become clear that the purchased whiteboard is a fake. The paint on such a surface can peel off, and the color with heavy use will quickly turn off white.
3) " Note the manufacturer when purchasing a whiteboard."
It must be checked and then in�
