Product Description 1.1 ApplicationsThe paper impregnation line use urea formaldehyde resin, phenolic adhesive to impregnate, coat, dry and stack paper base material.With the decorative paper impregnation line, for the production of:Melamine resin impregnated papers, for the Low-Pressure Laminates (LPL).Melamine resin impregnated overlay paper, decorative paper and balance paper for flooring.Melamine resin impregnated overlay paper for the High-Pressure Laminates (HPL)Phenolic resin impregnated paper for plywood lamination.1.2 Scope of applicationThe production line use fixed amount 40 ~ 250g/ square meters, width 900~1400 mm melamine/phenolic paper. The wet strength of melamine/phenolic paper is not less than 0.75kgf/15m.1.3 Environment for line runningThis production line is suitable for no corrosion and water soluble resin (Like urea resin, melamine and phenolic resin)High-temperature resistant requirement: F level, Explosion-proof gradeEnvironment temperature: 10~40oCRelative humidity ≤90% (Temperature at 20oC)Altitude not more than 1000m Part 2: Impregnation line parameters2.1 General parametersModelNTC1500A-2-3 Two Steps LineWidth of raw paper900~1400 mmMax. roller width1500 mmMechanical speed4~100 m/minWorking line speed15~18 m/min for melamine resinWorking height1350 mmHeating methodThermal oilDryer working temperature120~180oC2.2 Dimensions Raw paper roll diameterφ1100 mmWeight of roll paper1200 kgIn-diameter of paper axis3''(76mm)Dryer length3750 mmEffective drying length(2+3)× 3750=18750 mmEffective drying width1500 mmTotal line length~44,000 mmTotal line width~3800 mmTotal line height~4500 mmTotal line weight~46,000 kgsOperating areaOn the right side, run along paperDriving areaOn the left side, run along paper2.3 Power and energy consumptionDriven power3 phase,380V,50HzControl power2 phase,220V,50HzTotal installation power~125 KWHeating mediumThermal oilCompress air pressure0.5~0.7 MpaCompressed air consumption~8 m3/h as the installation volumeCooling water pressure0.2~0.4 MpaCooling water consumption~8 m3/h at 45 degree temperature weather which means biggest volume, This is calculated by 60m/min speed volume, if line speed is 30m/min then means only consumption 4m3/hRemark: Compressed air volume means max. Demand which means at maintaining when all the cylinders are open need 8m3/h also means installation volume. While the normally running consumption is 0.5 m3/h. But when paper is broken or changing paper, need to open all the doors then that time consumption is 2m3/h. So to make sure the line can be worked at all conditions, need to prepare the 8m3/h compressor. 2.4 Line capacity calculationThe real capacity of this model impregnation line not only depends on the design of the machine, but also depends on the glue mixed, paper quality, and the temperature of working environment, wind capacity of recycling fan, the mature operation of the workers etc.Calculation is based on:ResinMelamineTemperature inside oven120~180oCRaw paper density80 g/m2Raw paper width1300 mmResin contain of impregnated paper130%~150%Volatility of resin6~7%Working line speed20 m/minWorking time330 days/year x 3 shifts/day x 8 hours/shiftProduction capacity per day for 4x8 feet paper:15 m/min / 2.5 m x 60 mins x 20 hours = 7200 sheets papers per day at least. Part 3: Details of supplied machinery3.1 Semi-auto unwinder This unwinder is scroll type with two-axle type, it is equipped with two inflatable roll and safety chuck. When uncoiling, magnetic particle damping device could offer enough tension to paper. This machine has paper receiving device. It can make the new roll of paper to stick to the end of last roll of paper without stopping the machine, the high-speed cutter can cut the rest of last roll of paper to achieve continuously impregnating. One staff is enough for paper receiving.Including: frame, aluminum roller, damping device, paper receiving device, 2 set two cylinders' roller inflatable gas system, 2 set electronic magnetic powder brake and safety chuck. 3.2 Impregnator (First step dipping)Impregnating machine consists of frame, coating section, breathing system, impregnating roll unit, meter device, glue tank and heating device for glue tank etc.This impregnating machine is used in first impregnating. Using coating roller to do the single down side coating for the paper, angle size of coating is adjustable, then resin glue will penetrate into the paper from down side, and drive out the air from upper side completely. The coating device is equipped with breathing system, according to the different requirement for raw paper, resin glue and impregnating ways, the breathing system can control and adjust the height of breathing section, in this way to make the paper reach to enough amount of glue and adjust the flatness of paper. Resin infiltrate into the paper fabric and less low down the wet tensile strength, then the process of impregnating can go smoothly.Raw paper will be feeding into the glue tank after coating section and breathing section. Adjusting the gap of metering roll can control the resin content and impregnating uniformity of bond paper accurately, the motion accuracy of metering roll is ≤ 0.003mm.Configuration technical requirements: includes frame, S roller, Back coating part, Impregnating roller part, Metering roller φ290, Metering device, breathing system, the middle part of stainless steel (430) glue tank with spacers, the glue tank lifting and lowering is controlled by a worm gear reducer, and the metering roller adopts NSK bearings imported from Japan, the wall thickness of the roller can not be deformed, (the upper and lower motors of the breathing roller).It consists of:a) Frame structureb) Back side coatingc) Breath partd) Impregnator parte) Squeezing partIt has automatic and manual both operation model.In manual operation, the controller is in one side but can adjust two sides.In automatic model, it can adjust automatically by setting value through cabinet panel beside it.The gap between the squeezing rollers are shown in the screen, and you can adjust.It consists of below rollers:2 pcs steel roller with chromed surface with Φ290mm diameters, 3.5mm tube thickness, jumping accuracy is < 3 um under 100m/min speed, 0.3mm chrome surface and it has 50 CR hardness. f) Glue tankg) Glue tank heater 3.3 Dryer (6 sets Ovens) Pneumatic automatic big door for easier operation and better heat preventing;Three-layers heat insulations design to save energy 20% at least; 3.3.1 Drying ovens The machine consists of drying section, dehumidification system, automatic door, temperature control system, etc. The length of each drying section is 3750mm.The heating medium of the drying section is thermal oil or steam or natural gas direct burning system. According to the requirements of the drying process, each drying section is a temperature zone. The working temperature can be set independently and the temperature of the zone can be automatically controlled by the temperature control system, so that the actual temperature is basically consistent with the set temperature. ; The temperature is generally controlled between 120 and 180 °C. Each drying section has a wet outlet, and the opening of the wet outlet is controlled by a manual damper, and the operator sets the opening according to the process requirements. 3.3.2 Drying oven structure The frames of each drying section and air curtain section are welded parts of rectangular steel pipes and square pipes (50/100), with high strength and small deformation. The drying section is composed of bellows, air ducts, specially designed nozzles, hot air blowers, threading chain guides, etc. The frame is surrounded by thermal insulation wall panels and thermal insulation doors, and the thermal insulation doors are double-sealed and manually opened. Each section of the drying section has butterfly dampers up and down the hot air duct, the insulation layer is 15cm, 2 cold plates are used for the outer side, 2 galvanized sheets are used for the top plate, and 2 galvanized sheets are used for the inner side and the air duct plate.No.NameQty.ValueNote1Hot wind fan5 setsWFF-8.6# Motor5 setsY132M2-4 PowerKW15Has inverter2Moisture dryer fan1 setWFF-9.0# Motor1 setY00L1-4Liddell/BeidePowerKW22 3Hot air exchanger5 pcsTOCC-SR-01 Nozzle50 pcs import patterns4Platinum thermal resistance wire5 pcsPt100Press plenum6Temperature meter5 pcs America HONEY7Gas burner (If gas type)5 pcs Chinese brandSupply range: Drying units, moisture exhauster3.4 Roller Coater (Second step coating) The machine consists of frame, upper and lower mesh coated squeegee device, the second smoothing device, lifting devices.
