Desks and chairs processing technology determines the quality of good or bad
Apr 24,2024

We can find that with the improvement of the teaching level, the wooden desks and chairs originally used by the school have been basically eliminated, and most of the school now uses steel desks and chairs. Because steel desks and chairs are stronger and more durable than wooden ones.
However, steel desks and chairs will also have inferior quality, some manufacturers do not make good technology, there will be a desk surface spray began to fall off, steel parts rust.
Tell you that the correct production process should be: when the steel comes in and comes back, in order to prevent rust, the surface is treated. Then before spraying, it is necessary to remove the oil by pickling first, and the oil on the surface of the steel is removed by using a professional oil removal formula. Sometimes steel placed too long can not completely prevent the surface from rusting, and then the steel rust treatment. After oil removal, rust removal of the steel surface will become very smooth, after the completion of this step in order to prevent the steel from the rust removal liquid out of the air oxidation, need to be immediately phosphating. After the phosphating liquid treatment of the steel surface is attached to a thin layer of phosphating film, can be a good air to prevent the oxidation of steel. A series of processing processes are completed. Then before the plastic powder spraying, it must be ensured that the steel surface is dry and there is no dust, so that the plastic powder sprayed on will be tightly attached to the steel surface. Even if you hit it with a hammer, it won't come off easily.
The desks and chairs produced after strict treatment can generally be used for more than 5 years, and the plastic powder does not fall off and does not rust. Therefore, we recommend that schools must carefully examine the processing process of the manufacturer before purchasing desks and chairs. Be sure to check whether the quality is up to standard.
