濾板接觸物料平面及其孔洞均為PFA材質， 通過四氟模壓工藝將加熱后PFA粒料均勻包覆成型于鋼還外表面，產品一次成型、無接縫，耐腐蝕性完全由PFA材質固有特性保證，同時采用足夠的鋼胚厚度保證其使用的剛度和使用壽命。產品成型后外表面平整、光滑不易粘料，保證了裝配于設備后的密封可靠性和易清潔性。襯層厚度涌過國家標準高電壓電火花試驗檢測，保證安全性、耐用度。

     The surface of the fi lter plate contacting with the medium and its holes are made of PFA. The heated PFA particles areevenly coated and formed on the outer surface of the billet by the Teflon molding process. The product is formed at onetime without joints, and the corrosion resistance is fu lly gua ranteed by the inherent characteristics of PFA material. Atthe same time, sufficient billet th ickness is adopted to ensure its service stiffness and service life. After molding, theouter surface of the product is flat and smooth, and it is not easy to stick medium, which ensures the seal ing reliabilityand easy cleaning after assembly in the equipment. The thickness of the li ning layer is tested by the national standardhigh-voltage spark test to ensu 「e its safety and durability.
