What are the advantages of liquid filter bag?

  1. Stainless steel welding technology is generally used for the liquid filter bag. The horizontal error is less than 0.2mm, so that the sealing degree can be increased when it is installed in the equipment. In addition, the probability of side leakage can be reduced, so that the error of filter bag diameter is less than 0.5mm.


  1. The label on the filter bag indicating the product specification and model shall be easy to replace to prevent the pollution of the filter bag label and ink on the filtrate during use.


  1. Generally speaking, the products are produced by high-speed industrial sewing machines without silicone oil cooling, because this production form will not cause silicone oil pollution.


  1. The filtration accuracy is planned to be between 0.5 and 300 microns, and the materials are divided into polyester, polypropylene, nylon and other materials. Generally speaking, liquid filter bag products can be used in industrial liquids, such as ink, electroplating paint, chemical, food and other chemical liquids. Acid resistance and low mechanical strength of the fiber can also be reused.


In addition, the liquid filter bag ring mouth can have stainless steel ring mouth, PP ring mouth and PE plastic ring mouth, including various bag bottom and bag top plans. The liquid filter bag filtrate filter heads are specially singed, which can not only prevent the fiber from separating and polluting the filtrate, but also prevent the filter hole from being blocked by the traditional rolling treatment and shorten the service life of the filter bag.


All the materials are white without any special bleaching and dyeing treatment, which conforms to the environmental protection standard. Moreover, due to the three-dimensional filter layer of the needle felt, when the liquid flows through the filter bag, the particles will stay on the inner wall surface and deep layer of the liquid filter bag due to the deep filtration mechanism, which has high trapping power for solid or colloidal particles. The uniform thickness, stable opening rate and sufficient strength of the needled felt make the power of the filter bag stable and the service time longer. Five thread double needle tight sewing ensures that each liquid filter bag can achieve good filtration. It has a wide application plan and is suitable for liquid filtration in various industries.


Selecting a qualifiedfilter bag manufactureris one of the important factors to ensure the use effect of filter bags.
