Product DescriptionPaper Machine Doctor BladeDoctor blade is an important element in paper machine functionality, sheet quality and productivity. Doctors are basically scraping equipment required in many positions on a paper machine and coater to remove contaminants or water from the rolls and for special functions like creping and coating.FunctionFunction of Doctor Blade1. Removal sheet from the surfaces of cylinders and rolls.2. Cleaning the surface of the rolls and dryer cylinders.3. It adapts to the different characteristics of paper and the operating conditions of the paper machine, thus ensuring the quality of paper and production efficiency.Different Material ApplicationForming SectionPress SectionFiberglass: microfiber combined with flexible expoy resin,excellent adhesion to roll surface , excellent chemical property, 185 degree temperature resistence.HDPE : 80 degree temperature resistence.Expoy Resin:excellent chemical resistance expoy resin, excellent wear resistance, 160 degree temperature resistence.Glass Fiber: Microfiber combined with flexible expoy resin, excellent adhesion to roll surface, excellent chemical property, 185 degree temperature resistence.Carbon Fiber:We have 20%,40%,60%,100% carbon fiber doctor blade. Blades and roll surface have excellent adhesion, 185 degree temperature resistence.Stainless Steel: Quenched stainless steel (containing 13% chromium), hardness HRC 42-46, standard thickness 1.2mm, also can customized.Expoy Resin:Microfiber combined with epoxy resin ,excellent chemical properties,185 degree temperature resistence.Expoy Resin MaterialCarbon Fiber MaterialHDPE MaterialApplication: Various rollers from the wirese ction to the winding section.Excellent chemical properties, 185℃ temperature resistance.Application: Ceramic rolls, mirror rolls and soft calender rolls.100% carbon fiber pressed.

The surface of roller or dryer is uneven2. The doctor holder is damaged or dirty3. Sediment1. Use a softer blade2. Clean, repair or replace the doctor holder3. Use abrasive bladeExcessive wear on middle or edge of blade1. The blade is not installed on the top of the roller2. The old blade sinks (or leaves) the roller or dryer1. Refit or add gasket at the back of blade if necessary2. Replace the old and sunken bladeExcessive wear at one end of bladeThe displacement of blade is not parallel to the axial direction of roller or dryerAdd gasket, if necessary, move bearing and bracket to adjust scraper parallel to axial directionThe blade is worn evenly, but the end face is rough1. There is deposit on the surface of roller or dryer2. The pressure of blade is too high3. The material of blade is too hard1. Use abrasive blade when necessary2. Reduce the pressure3. Use a slightly soft bladeExcessive wear in sheet areaThe sheet leaves sediment on the roller or dryer1. Use abrasive blade when necessary2. Trim the edge of blade frequently3. Use blade with slotted end to prevent excessive pressure on both ends of roller or dryerExcessive wear out of sheet areaThe sheet lubricates the roller or dryerUse blade with slotted endLocal depressionThe blade is damaged, electrostatic (discharge/ electrolysis /heating)Insulate the blade from the holder or use a non-metallic bladeThe blade produces burr1.The material of the blade is too soft2. The pressure is too high3. The angle of the blade is too small1. Use a slightly hard scraper2. Reduce the pressure3. Adjust the bearing or bracket to increase the angle, and use the instrument to check and correct the angleProduction EquipmentQuality Test Before ShippingPacking & Shipping1.Bubble Film and waste thick fabric wrapping while protecting inside fabric.2.Wrapped special fabric package outside(air shipping).3.Composite wooden box(sea shipping).Company ProfileSUN HONG PAPER TECH XUZHOU LTDSun Hong Paper Tech was established in 2010 and is located in Xuzhou City, Jiangsu Province.
