The characteristics of the polybag filter bag? 1. High pollution capacity, high flow rate, high pressure resistance 2. The operation is convenient, the corrosion resistance is strong, and the temperature is good. 3. The interception rate is high, the cost is low, and the scope of application is wide. 4, acid alkali resistance, temperature 150 C 5, polyester fiber, deep filtration, precision range of 0.5~600 mu m filter bags are usually divided into many kinds according to their own performance. Each has its own characteristics. Taking liquid filter bags, there are four main characteristics. No high protrusion improved 1. liquid filtration bag suture, so it won't happen without the needle and lead to the occurrence of the phenomenon of side leakage phenomenon. 2. liquid filter bag material is divided into polyester and polypropylene nylon, such as filter bag type, the range of filtration precision is high. 3., the label of product specification and type label is all selected for liquid filter bags. The purpose is to prevent the phenomenon of contamination of filter bags and ink in filter bags. 4. liquid filter bag will not produce silicone oil pollution problem, because the design is made of high speed industrial sewing machine without silicon oil cooling. First of all according to the fluid to be filtered chemical name, chemical incompatibility to find available filters, commonly used by PE, PP, PTFE, NMO, and then according to the operating temperature, operating pressure, pH value, operating conditions (e.g., whether it is necessary to withstand steam, hot water or chemical sterilization), one by one assessment and remove the filter not applicable. Use is also an important factor to consider, such as medicine, food or cosmetic use of filter material must be granted by the FDA material; ultra pure water must be purified, without releasing material which may impact the impedance of the filter; filtration gas must be hydrophobic material as well as the need for hygiene filtration design etc.. The main foreign filter bag manufacturers have GAF, FSI, 3M, CUNO, U.S.Filter, LOEFFLER, PARK, Vablue filter bag, etc.
