Стеклопластик фильтр ткань для сбора пыли

Description Fiberglass filter clothFiberglass filter cloth is able to bear high temperature, and has already widely used in cement factory ,chemical industry,incinerator, etc . it is a kind of perfect material for high temperature . it is widely used in protecting from polluting and recovering valuable powder. High separation at start up & during operationHigh separation efficiency at high air to cloth ratio allows for large increase in productivityLow resistance to flow generates high airflow rate & low-pressure build up.Low pressure build up means less frequent cleaning. Reduced cleaning pressure yield significant decline in energy costs.Reduced cleaning pressures mean less stress on fabric resulting in less stretching & hence lower replacement cost.Lower propensity to blind results in longer service life & hence reduced replacement cost.High air to cloth ratio means less number of bags in a smaller dust collector resulting in capital lost.Chemically inert & thermally stable to high temperatures.FILTERATION FABRIC FINISH Without a finish or protective coating the gas filaments in filtration fabrics can break when flexed during normal usage. Breakage results from flaws forming on the surface of glass filaments flaws can be created by abrasion or chemical attack. Finish selection should be made on the basis of the flew gas chemical composition and type of particulate. 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. 625 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 FB302High Temperature Woven FiberglassSepcificationFinish PTFE,silicon,graphiteLoss on lgnition(%) ≥2Weave Pattern 1/3 twillThread Count ( No./cm) 17.5×9.5Weight (g/m2) 450--500Mullen Burst(kg/cm2) ≥45Tensile Strength (N/25mm) Warp ≥2000weft ≥1200Air Permeability(cm3/cm2/s·127pa) 20-36Material E-fiberglassContinuous Service Temperature <260°CApplication Ferroalloy,nonferrous metal
