Brush epoxy resin anti-corrosion in the mechanical filter, use acetone to adjust the resin, what is the ratio, how much curing agent! Bottom preparation: 100g epoxy resin,Thinner 40-60 grams,25g low temperature curing agent (T31;Preparation of putty material layer (sticking ring cloth layer) and surface layer: 100g epoxy resin,Thinner 10-20 grams,25g low temperature curing agent (T31;Preparation sequence: After the epoxy resin is heated and melted (direct heating is strictly prohibited,Use the container for consumption,Then mix well with the thinner.Add curing agent again,After mixing, use it.Preparation is completed.After the preparation is completed, the epoxy resin should be used within 2 hours.Name of glass cloth: surface felt,The thickness is about 0.1 bottom,Sand blasting at the base,After the acetone was cleaned,Brush epoxy,2 Put a layer of glass cloth,Paste real,No bubbles,No wrinkle,Note: thinner generally can not be adjusted with acetone when brushing epoxy resin with acetone,Because aceto
Central air conditioning filter The central air-conditioning filter is widely used to purify air-conditioning air filtration and dust removal. the filter materials are non-woven filter cotton and nylon mesh, and the metal square mesh is used as support,Filter efficiency has G1-G4 grade, weighing method, the style is divided into plate type, bag type, folding, nylon mesh.The outer frame is cardboard and aluminum profile,The first filter in the purification system,It can also be used separately as an air inlet filter for ordinary air conditioning systems.Any ventilation, air conditioning and purification system with a medium-efficiency bag filter and a high-efficiency filter,Coarse air filters should be installed.Classification and use of central air-conditioning filter net primary effect central air-conditioning filter net is used for pre-filtration of special air-conditioning and large ventilation systems in computer rooms,Air conditioning clean room air filtration,Pre-filtration with efficient filtration,
