Technology of paint manufacturing
For the production of waterborne paints, it is desirable to use a mixer - dissolver, which may be if it's possible, sure, necessary stirring together easily combined components of the frame ( anchor ) and simultaneously stirred to disperse loose paint components ( pigments and fillers ) milling stirrer disposed, which is eccentrically relative to the central shaft of the frame ( anchor ) mixer.
Different chemical plants offer raw materials for paint manufacturing, so it's a complex process a basically proceeded in a few industries. There are no manufactures, which can produce varnish and paint materials and also raw materials for paints. Typically, the mixing frame ( anchor ) is carried out at low stirrer speed ( 60-120 rev / min), dispersing the same loose components produced by milling with a shaft speed of 1000-1200 rev / min. In the absence of the above-mentioned multi - dissolver mixer for the production of water-dispersion paints - dissolver with a central shaft with cutter without frame agitator can be used. Calculation of parameters of the dissolver with a central shaft, allowing for an effective dispersion process is attached.
Since the water- dispersion inks are corrosive medium having a pH of from 8 to 10 and above, in the manufacture of paints, it is desirable to use all the capacity equipment made of stainless steel or glass inside and the communication conduits, - stainless steel.
Handling of finished paints and dispersion through pipelines to the production line waterborne paints are only needed to use screw pumps, because centrifugal and gear pumps ( as the most common in the paint industry ) destroy the dispersion and lead to loss of the properties of paint. The pressure exerted by the screw pump can hesitate within 3-8 atmospheres, depending on the pipe diameter. If the line diameter is 89-102 mm, the approximate capacity of a screw pump can be 5-8 atm.
So, now you can know, that paint manufacturing is a hard process, that's why we recommend you to look through our raw materials for paint productionon our web-site. There is a big list of raw materials of paint in our company, e.g. solvents.
