The construction of the CPF candle filter is a testament to engineering precision. At their core, is the polymer filter element, a vital part engineered to efficiently trap contaminants and impurities. These filters bear a resemblance to candles, and are crafted from high-quality materials which are capable of withstanding the extreme temperatures and pressures encountered in polymer manufacturing. Crafted from materials like sintered metal or ceramics, the polymer filter element forms the foundation of all CPF candle filters. This core houses an intricate network of channels, forming a sophisticated filtration pathway.
The term polymer candle filter signifies precision and excellence in ensuring the purity of polymer products. CPF candle filters operate as polymer melt flows through them. Along this complex path, contaminants are captured, leaving behind only the pure polymer. It's a process that guarantees the final polymer product meets the strictest quality standards.
The main filter layer of Pleated Filter mainly uses two materials: stainless steel wire mesh and stainless steel Sintered fiber. Stainless steel wire mesh is woven from stainless steel wire. Its pleated filter has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature. Its pleated filter has the characteristics of high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.
