Knowledge Of PP/PTFE/PE/Nylon Filter Bags

Today, let's briefly introduce polypropylene PP filter bags. Polypropylene filter bags, abbreviated as PP filter bags, are made of polypropylene non-woven fabric. Polypropylene PP filter bags are thermoplastic plastics made by polymerization of propylene. Polypropylene is a non-toxic, odorless, and tasteless milky white high crystalline polymer with a density of 0.90-0.91g/cm3, making it one of the lightest varieties of all plastics. Hit by water, particularly stable, with a water absorption rate of only 0.01% and a molecular weight of approximately 811000. Good formability, good aging resistance, good chemical properties, almost no water absorption, and no reaction with most chemicals. Acupuncture treatment for proliferation of fibrous tissue cells. At the same time, it belongs to the dual resistance mode: the internal honeycomb structure can effectively remove solid and soft particles. In other words, large particles of impurities are blocked by the fiber surface, while fine particles are trapped deep in the filter element and used. Due to the increase in pressure, the process is not damaged and the filtration efficiency is high; In addition, this product can effectively prevent the outer layer from being exposed to high-temperature surfaces. Heat treatment (i.e. the application of rapid sintering technology, due to the rapid impact of liquids during printing, dyeing, and filtration processes, resulting in fiber loss) to ensure no damage. Traditional rolling treatment can prevent clogging of filter holes and shorten the service life of filter bags. At the same time, the pressure difference is small and the flow rate is not affected. The accuracy is 0.2-200um, etc.
