powder coating now

Powder coating has high mechanical strength, no pollution, save energy and resources, but 

it also has some disadvantages, such as curing condition to drink high, and easy to be 

uneven. Plus the paint classification standards, quality of coating is produced on the 

market is uneven, with production equipment and varieties than abroad have difference on a 

big cut, the need for further technological innovation, the enterprise market competition 

order and supporting raw materials also need to be further improved.

With the aggravation of the market competition, the homogenization of powder coating has become more and more obvious. Functional paint not only to break the phenomenon of the same paint products, but also directly to the product positioning. Functional paint itself does not contain any toxins, is widely used in home decoration and other places. It is based on a certain 

function and market segments, although the surface needs to become smaller, but in fact, it 

directly leads to consumer spending, and thus promote the product sales. The development 

prospect of the work is more and more broad, believe that in the next five years, it will 

be distributed to every area of demand in our country, and will become a major development 

direction of the paint market.

Coated epoxy powder coating is generally used in high voltage 

electrostatic spraying and friction electrostatic spraying two methods, the thickness of 

the coating is about 60 - 150um, can be adjusted according to the specific construction 

standards. Prior to painting, you should first apply the oil, rust and other impurities on 

the surface of the object, and then sand blasting or shot blasting. Dust removal work on 

the pipe surface must be in place, and the dust removal is close to the white level. The 

next step is to preheat the workpiece, the temperature is best to control between 180 

degrees Celsius and 220 degrees Celsius, the temperature should not be too high. Then the 

powder coating can be sprayed on the surface of the pipe by electrostatic spraying. 

Finally, the coating will be accomplished by cooling.
