The spray machine has a history of more than one hundred years since it was invented. In this one hundred years, the spray machine from scratch, from simple to perfect, has been in the process of application to upgrade and transform. But generally speaking, the substantive is not much change, in most cases the change is the shape of the spray machine above.

In the past, some air spraying, there are some problems, for example, the utilization rate of paint will be very low, and sometimes it will be permeated in the air, which is a kind of harm to the atmosphere, but also easy to be inhaled into the body caused by poisoning. Later, Americans seem to have realized the serious impact of some painting industries on the atmosphere. So in 1996, the United States issued a legal document, there is a very important statement in the document, is to make restrictive provisions for the content of paint mist in the spray gun, so that the traditional spray machine due to obvious defects, is prohibited by law and not allowed to use.

However, the painting industry can not easily give up because of the promulgation of legal documents. Therefore, this technical problem forces scientists to carry out technical reform on the spray machine.

First of all, it is to improve the efficiency of the spraying machine, which will soon have results. However, this is accompanied by some other problems, such as the inability to atomize high-viscosity paint and increased investment costs. If the viscosity of the paint itself is too high, the spray machine is not able to atomize, and over the time limit, the machine will stop atomizing. The more problems there are, the more things need to be improved.

In 1998, the European spray machine was reformed again, this reform is mainly to reduce the use of air, at the same time, the ability to atomize has been improved, some paint with high viscosity will not worry about not being atomized at this time.

This reform also coincides with the previous 65 percent paint utilization rate, making the painting industry a big step forward. At the same time, people will not pay too much attention to the painting industry's high influence on the atmospheric environment. Because after the improvement, the performance of each part of the spray machine has been greatly improved. It is at this time that the spraying machine has been gradually spread in some surrounding countries, and some painting industries have been further developed because of the help of the spraying machine.

Because foreign countries are the inventors of the spray machine, so in the performance of the equipment, some foreign equipment will have certain advantages in some aspects. However, there is also a comprehensive consideration when purchasing.
