Characteristics of polyester screen and stainless steel screen
Polyester screen, also known as polyester screen printing mesh, is a kind of printing screen, which is also made of chemical synthetic fiber and belongs to polyester system.
Advantages and disadvantages of different kinds of printing screen
Screen printing belongs to orifice plate printing, which is one of the four major printing methods together with flat printing, convex printing and gravure printing. In addition to screen printing, perforated plate printing also includes printing plate, stencil and spray printing. One of the screen printing is to transfer the ink to the substrate through screen printing and squeegee.
The difference between nylon mesh and vinyl mesh
Nylon mesh and ethylene mesh are two kinds of plastic wire mesh products which are widely used. Together, they are also products that many customers simply confuse.

Some points should be paid attention to when selecting filter bag for wet gas
The liquid filter bag can have stainless steel ring, PP ring and PE plastic ring, including various bag bottom and bag top designs. The filtrate surface of the liquid filter bag is treated with special singeing, which not only effectively prevents the fiber from separating and contaminates the filtrate, but also avoids the filter hole from being excessively blocked and shortens the service life of the filter bag caused by the traditional rolling treatment

Nylon filter screen is mainly made of P.P fiber textile forming
The nylon filter screen is mainly made of P. P fiber by textile forming. Acid and alkali resistance, good corrosion resistance. Low resistance, can be repeatedly cleaned, high economy. The long and short fibers and dust particles are easy to clean, and the filtering efficiency is not affected by cleaning. Good impact strength.
What are the requirements for a good screen
The mesh is made of stainless steel wire, high carbon steel wire, low carbon steel wire, medium carbon steel wire, nylon and polyester monofilament. What are the conditions for a good screen?
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.
Analysis on several common damage reasons of filter bag
If the jumper or off-line is easy to burst the bag, the pressure loss of the filter bag will increase during operation, and the impurities will scale, which is a great test of the filter bag material and workmanship
How to confirm the number of printing outlets
In printing plate making, the selection of dot angle plays an important role. Selecting the wrong dot angle will result in interference fringes.
