东北工学院和丹东市毛毯厂共同研制并已批量生产的DV系列化学纤维滤料,是以涤纶纤维为骨架,以维纶(聚乙烯醇)纤维为粘合材料,应用新型工艺制造的。材料来源充足,粘合均匀,并具有以下特点: 1.滤料沿其厚度方向有密度梯度,因而具有效率高、使用寿命长、阻力小和容尘量大的特点。应用这种滤料,不仅能保证较高的和稳定的净化效率,而且可以提高过滤器的处理能力和减少过滤器的占地面积。
The DV series chemical fiber filter materials jointly developed by the Northeastern Institute of Technology and Dandong City Blanket Factory are manufactured using a new type of process, using polyester fibers as the skeleton and Vinylon (polyvinyl alcohol) fibers as the bonding material. Adequate material sources, uniform adhesion, and has the following characteristics: 1. The filter material has a density gradient along its thickness direction, which has the characteristics of high efficiency, long service life, low resistance and large dust holding capacity. The use of this filter material not only ensures a high and stable purification efficiency, but also improves the filter processing capacity and reduces the filter footprint.
