In response to the increasingly stringent filtering requirements and the zero-leakage filtering requirements for some special situations, Huazao has specially developed the international leading level of all-welded filter bags. Made of polyester and polypropylene filter felt imported from Europe. The surface is specially treated with singed wool to ensure that no fiber is separated from the filter material, resulting in the fouling of the downstream filtrate. The filter material is made by acupuncture, and the acupuncture method creates a three-dimensional filter layer. The principle of deep filtration is adopted. The liquid flows through the winding path to intercept the particles and hold them in the surface and deep layer of the filter bag, which has a high ability to capture solid or colloidal particles. Material thickness, the stability of the hole gap size and to strengthen the mechanical strength and get better efficiency of filter bag, online longer wait for a characteristic, filter bag adopts full fusion welding process, so there is no traditional sewing technology for need to high-speed, sewing thread with silicone oil cooling caused by pollution, no electricity leak phenomenon caused by the eye of a needle. Meet the production technical requirements of electronics, food and other industries.
The plastic ring produced by special mould selection of high-quality engineering plastics, with excellent physical properties and chemical corrosion resistance, bag mouth integrated handle higher than the liquid level, convenient to replace the filter bag to improve work efficiency. The plastic ring has been specially designed to be suitable for almost all bag filters on the market today. All the plastic circle filter bags produced by our factory are compatible with any specification in no. 1~4 bags. The daily output can reach 500 all - welded filter bags. The filtration materials are polyester and polypropylene respectively. The filtering accuracy ranges from 1 to 200 backfill meters.
