一、滤纸的物理特性与滤纸功能的联系
I. THE RELATIONSHIP BETWEEN THE PHYSICAL CHARACTERISTICS OF FILTER PAPER AND THE FUNCTION OF FILTER PAPER
1. 定量
1. Quantitative
在过滤器中，数量第一，性能在过滤器组件，价格。对于过滤器，过滤区域是确定的。在一定的过滤面积下，比越大，滤纸越重，滤纸越重。因为滤纸在滤芯上的花费，占比较高，所以滤芯的花费也较大。
In filters, quantity first, performance in filter components, price. For filters, the filter area is determined. Under certain filtration area, the larger the ratio, the heavier the filter paper and the heavier the filter paper. Because the cost of filter paper on the filter element is relatively high, so the cost of the filter element is also larger.
2的厚度。
Thickness of 2.
滤纸的厚度限制了滤芯的最大过滤面积。
The thickness of the filter paper limits the maximum filter area of the filter element.
3.刚度和抗破碎性，说明滤纸具有抗变形、抗压差能力，刚度高，抗破碎性好，说明滤纸耐久性好，但刚度过高，易脆，滤纸损坏。
3. Stiffness and crushing resistance show that the filter paper has the ability to resist deformation, differential pressure, high stiffness and good crushing resistance. It also shows that the filter paper has good durability, but its stiffness is too high, brittle and the filter paper is damaged.
4. 树脂含量
4. Resin content
滤纸中加入树脂，是比较添加滤纸，在滤纸加工中定型，根据应用不同，一般在10 ~ 30%之间。树脂含量过高，树脂简单，滤纸孔结构堵塞。
Adding resin to filter paper is a comparison between adding filter paper and setting in the process of filter paper. According to different applications, it is generally between 10% and 30%. The resin content is too high, the resin is simple and the pore structure of filter paper is blocked.
2. 滤纸的过滤特性与过滤功能之间的联系
2. The relationship between the filtration characteristics and the filtration function of filter paper
1. 滤纸的透气性
1. Air permeability of filter paper
透气性是滤纸性能的反映，是滤纸设计的首要考虑因素。它与过滤器的流动阻力特性、过滤功率、原始阻力、寿命等功能目标密切相关。滤纸的透气性越大，流动阻力越小，原始阻力越小，反之亦然。透气性与流动阻力呈反质的关系。
Air permeability is the reflection of the performance of filter paper and the primary consideration in the design of filter paper. It is closely related to the flow resistance characteristics, filter power, original resistance, life and other functional objectives of the filter. The greater the permeability of filter paper, the smaller the flow resistance and the smaller the original resistance, and vice versa. The relationship between permeability and flow resistance is inverse.
透气性也是滤纸防潮的指标。滤纸的透气性越高，越容易吸湿。加工规模不稳定，影响批量生产。处理功能差。恶劣的条件造成了质量的下降。滤纸的长度为2 ~ 4mm，影响滤芯的高度。粘接后受潮影响，滤纸膨胀，滤芯变形，严重影响滤芯质量。
Air permeability is also an indicator of moisture resistance of filter paper. The higher the air permeability of the filter paper, the easier it is to absorb moisture. The unstable processing scale affects the mass production. The processing function is poor. Bad conditions have resulted in a decline in quality. The length of filter paper is 2 to 4 mm, which affects the height of filter element. After bonding, the filter paper expands and the filter core deforms, which seriously affects the quality of the filter core.
2. 最大孔径和均匀孔径
2. Maximum and Uniform Aperture
最大孔径和均匀孔径可以用气泡法测量。最大孔径，是顶泡压力计算的孔径。均匀的孔径，是群泡点压力计算的孔径。
The maximum and uniform aperture can be measured by bubble method. The maximum pore size is the calculated pore size of the top bubble pressure. The uniform pore size is the pore size calculated by the group bubble point pressure.
滤光片的完备性由泡点实验决定，滤光片的精度由均匀孔径和最大孔径的大小近似决定。均匀孔径与滤波功率密切相关。均匀孔径越小，滤波功率越大。
The completeness of the filter is determined by the bubble point experiment, and the accuracy of the filter is approximately determined by the uniform aperture and the maximum aperture. The uniform aperture is closely related to the filtering power. The smaller the uniform aperture is, the larger the filtering power is.
