The use of filter bags in the use of filter products is relatively simple, so everyone will want to maximize the filter area, you want to do this, it is recommended that the filter cloth must be placed flat, do not fold. After a period of use, change the filter cloth or clean the filter cloth in time to ensure the cleanness on the filter cloth. The
When the filter bag is in use, the surface of the filter bag is mainly screen material, and the depth filter is made of felt material. The screen material (nylon monofilament, metal monofilament) directly traps the impurities in the filter on the surface of the material. The advantage is that the monofilament structure can be repeatedly cleaned and the cost is low. The disadvantage is the surface filtration mode, which can easily cause the surface of the filter bag to clog. This type of product is most suitable for coarse filtration applications with low precision and the filtration accuracy is 25-1200μm.
The
Felt material (acupuncture cloth, melt-blown non-woven fabrics), the deep three-dimensional filter material commonly used in the process of use, the main characteristics of its material is the fibrous tissue is relatively loose, the entire product high porosity effectively increases the impurity Capacity interception, this type of fiber material is a complex interception mode, that is, the larger particulate impurities are trapped on the fiber surface.
Fine particles of the filter bag are trapped in the deep layer of the filter material, so the filter has a higher filtration efficiency. In addition, the high-temperature surface heat treatment, that is, the application of instant sintering technology, can effectively prevent the fiber from being scattered by the fluid at high speed during filtration; the felt material is It is of disposable type (disposable) and has a filtration accuracy of 0.1-200μm.
The
Filter bag in the use of its two filtering methods are mainly determined by the form of the filter material, the membrane material filtering method is the hole intercepted on the surface of the material, in the use of the surface filtration, so that the product can be cleaned and used multiple times .
