Qingdao Star Machine is a chemical properties acid and alkali resistance filter cloth factory. The selection of chemical properties acid and alkali resistant filter cloth is crucial for the effectiveness of filtration, and the filter cloth plays a crucial role in the use of filter presses. The quality of its performance and the correctness of its selection directly affect the filtering effect. The commonly used filter cloth at present is synthetic fiber woven filter cloth, which can be divided into several types according to its different materials, such as polyester, vinylon, polypropylene, nylon, etc. In order to achieve ideal interception effect and filtration speed, the selection of chemical properties acid and alkali resistance filter cloth also needs to be based on the particle size, density, chemical composition, and filtration process conditions of the slurry. Due to the different materials and methods used for weaving filter fabrics, their strength, elongation, breathability, thickness, etc. are all different, which affects the filtering effect. In addition, the filtering medium also includes cotton fabric, non-woven fabric, sieve, filter paper, and microporous membrane, which are determined according to actual filtering requirements.If necessary, the chemical properties acid and alkali resistance filter cloth we can provide free samples.
