Wavy-shaped plastic sintered filter plate dust collector (also known as sintered plate dust collector) is made of material from various polymer powder compounds, which are strictly mixed before casting and sintering. This forms a porous matrix, then a special spraying process fills the gaps on the surface of the plastic sintered plate with ultra-fine dust particles less than 1-2 micrometers, achieving high dust removal efficiency and ultra-low emissions, meeting the requirement of smoke and dust emission concentration at 3-5 mg. It is particularly suitable for the treatment of ultra-fine dust from coarse rolling machines. The plastic sintered plate not only has high dust removal efficiency but also a long service life, with domestically produced models lasting 8-10 years.
