If the paint is not filtered

In the process of equipment, the paint will participate in some matching resin linker auxiliary agents. Some raw materials contain particles and impurities in the production and processing process. In addition, the incomplete dissolution and particle agglomeration will occur sometimes when participating in the opening of matching solvent.

It can be imagined that if the paint is not filtered, there will be many abnormal particles on the surface of the product after spraying. Forming a large area of poor spraying products, virtually increased the cost of production. So it is very important to choose the right filter cloth to filter the paint. How to choose the right filter cloth?

Let's talk about it from several aspects. In general, white nylon mesh units are used in the occupation. They are generally divided into 100, 150, 200, 250, 300, 350, 400, 450, 500 mesh. As for how to choose the mesh, you need to select for each different paint.

First of all, let's take a look at the powdery paint, that is, the paint contains the same silver powder, pearl powder, fluorescent powder, rubber powder and so on, which are generally used under 300 mesh and above 100 mesh. If you don't know how much is suitable to use in the early stage, you can do some tests and choose 200 mesh two-layer filtration speed. If the filtration speed is very fast, you can choose 250 mesh or 300 mesh slightly more dense.

If the filtration is very slow, you need to select a smaller mesh such as 150 mesh or 100 mesh, so that the paint can move naturally like the next container. Generally, try to filter a bucket of 13kg paint in about 2 minutes without reference. If is does not take the powder for example some solid color or the bright color paint needs to use 300 mesh above 450 mesh below the filter cloth method to refer to the above. If some of the topcoat varnish claims to directly select 450 mesh to 500 mesh filter screen.
