woven glass for steel plant as filter material

Specifications This kind of woven glass for steel plant as filter material use for making filter bag,then use in cement , steel plant .

 Description Hongyuan woven glass use for making filter bag which usually use in bag house.   FILTERATION FABRIC FINISH     TRIPLE FINISH: the triple finish was one of the earliest finishes developed for filtration fabrics. It consists blend of silicon oils, graphite & PTFE. The three finishes components combine to protect the glass fabric from abrasion, but offer only limited protection from chemical attack. the triple finish is now used primarily in cement production and metal foundry applications. PTFE FILNISH:A ten percent add on of PTFE particles, such as DUPONT”S TEFLON B, encapsulates the glass fibers to prevent abrasion. However, because PTFE does not bond to the glass filaments, acids or alkalis can attack fabric with a PTFE finish chemically. Fabric with PTFE finish is recommended for use with utility base load boilers Operating under mild PH conditions.  ACID RESISTANCE :this proprietary finish consists of acid resistance polymers, PTFE GRAPHIT & SILICON OILS. The acid resistance polymers form a covalent bond with molecules on the surface of the glass. The bonded polymer forms a protective barrier around the glass surface to shield it from chemical attack. The acid resistant finish is recommended for filtration of flue gases in an acid environment such as carbon black  & industrial utility boiler   SPECIFICATION   1.loomstate glass fabric
