In the automobile filter, the papermaking-fiber suspension has a concentration of 11%-16%, and it flows onto the forming net under careful control to leave a uniform fiber layer after being dehydrated. Vacuum suction and dehydration on the forming wire make the paper web strong enough to bear its own weight, that is, it is pulled down from the web and sent to the press section to squeeze out more water. Compress to an unqualified level and lose permeability). Drying the paper web to remove remaining moisture is usually carried out by surrounding a series of steam-heated drying cylinders.
The structure of the medium (such as woven mesh) is easy to define. According to its definition, its filtering performance is easy to understand. The structure of paper is extremely complex, and Corte has been quite successful in trying to explain the structure of paper using approximate mathematical models. Paper pages are an incomplete hierarchy.
Analyzing the distribution of straight rods based on the frequency of fiber/fiber intersections and the average length between the intersections, we can understand the mechanism of the strength properties of the paper. The polygonal open space distribution is related to porosity. This problem is very complicated. Only by further approximation can the structure be simplified from polygon (in a random network, the average value of the sides is 4) to rectangle.
Taking into account that the cross-section of each pore in the long direction is irregular and the diameter is variable, in order to further analyze this structure, a straight circular tubular pore with an average radius is used to replace it. The average length of the penetrating pore depends on Depending on the flow method applied, and the same paper presents different pore distributions depending on the flow characteristics through it.
