Cage culture originated in Cambodia and other Southeast Asian countries in the late 19th century, and then spread to all over the world. In the 1970s, cage culture began in China.
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
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.
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?
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.
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
In printing plate making, the selection of dot angle plays an important role. Selecting the wrong dot angle will result in interference fringes.
Nylon filter bag is made of high-strength nylon woven mesh sewing, and common binding skills are used to avoid pinhole leakage to a large extent, and impurities larger than the mesh in the filtration are directly retained on the surface of the data; particles smaller than the mesh diameter enter the downstream through the mesh, so the nylon monofilament filter bag completes the surface filtration, and the lubricating surface is convenient It can be reused for cleaning.
The filterability of the filter screen is widely used in the coal mining industry of the petroleum industry, but there are many kinds of raw materials for the stainless steel filter screen, including nickel 2Ni 4ni 302 304 316 316L, Of course, according to the different service life of the raw materials, their raw materials are difficult to distinguish from their appearance.
