Paper is the choice of polyvinyl alcohol polymer plate was modified by adding pore-forming agent, low temperature setting, cutting, cutting, testing completed. This product has the following characteristics: 
 1. Innovative: This product filtering speed, high precision, to overcome the uneven pore sponge filter, not widely used, pressurized heat deformation of the shortcomings aperture zoom. 
 2. Advancement: in the international filtration industry, filters, filter, filter cloth, filter and effect of such filtering can not reach the technical specifications for this product. 
 3. Reliability: This product is used in the shipbuilding industry proven test results and test results using the same batch. 
 Polymers are chemical products in the field of paper plates for multi-layer filter. For ships, machinery, automobile filters and other industries. It has a certain degree of flexibility and strength, with basically the same size and uniform distribution of pore filter, and filter pore size and plate thickness can be controlled on demand; immersed at room temperature (below 70 ℃) of liquid or gas, the shape invariant , pore size remained unchanged; the use of non-fiber shedding, filtering and high precision, easy to clean up cleaning, can be reused; and water, oil, good corrosion resistance, long life, wide range of applications and other characteristics.
