Product Name: Aluminum Boday Teflon Coating PU Spray Foam Dispensing Polyurethane Gun Model NO.: KNBL-140 Compass: Aluminium Alloy Teflon Coated Barrel: Iron Nickel Plating Gun Body: Aluminium Alloy Trigger: Iron Nickel Plating Head: Brass Regulating Screw: Imitation Gold Copper Handle: Plastic Environmental Protection Trademark: ODM, OEM Transport Package: Colour Box Specification: 64x34x27CM Origin: China HS Code: 8424200000 Product Description The spray gun comprises a gun body and a gun head, which are connected by a connecting mechanism; the gun head comprises a nozzle, in which a number of metal round steels are plug welded; the connecting mechanism comprises a flange and a chain pin, and the nozzle is made into a flat shape; the replacement is convenient, the cost is low, and the gun head can be effectively prevented from falling off and wearing.In the spraying process, improper spray gun operation will affect the spraying effect of the product. Good spraying effect is shown in: 1. Average coating distribution. 2. The coating should not be too thick or too thin.Several problems to be noticed in spraying:1.Movement speed of spray gun.In the spraying operation, the moving speed of the spray gun has a great influence on the coating effect.1). If the manual spray gun moves too fast, the coating on the surface of the coating is thin and dry, with poor leveling and coarseness;2). If the moving speed of the manual spray gun is slow, the coating on the surface of the coating must be very late, and it is easy to produce the phenomenon of sagging.3). The best moving speed of spray gun is that after spraying, the coating on the surface of the coating is full, uniform and wet. This needs to be controlled by operators with certain spraying experience.2.Control of the trigger.The gun is controlled by the trigger. The deeper the trigger is pulled, the greater the liquid flow rate. In the process of traditional gun walking, the trigger of electrostatic spraying equipment is always buckled, not half buckled. In order to avoid the accumulation of paint sprayed at the end of each walking gun, experienced painters should slightly loosen the trigger to reduce the paint supply.3.Orientation of spray gun to substrate surface.The spray gun should be vertical to the substrate surface, or try to be vertical. If the spray gun is a little askew, the result will surely cause the spray band to flow to one side, while the other side will appear thin and lack of paint, which is likely to cause stripe coating.4. Distance between spray gun and substrate surface.For the siphon spray gun, the best working interval is 15 ~ 20cm. If the interval is too close, it may produce flow, and even cause the color inconsistent with the expected when spraying metallic flash paint or pearlescent paint. If it's too far apart. More than 20cm, it may lead to dry spraying, over spraying and poor leveling of the coating. If the metallic flash paint is sprayed, the possibility of color change may also exist. The pressure spray gun can be far away from the base material. Generally, the best interval is 20 to 30 cm. These are the principles that must be followed when spraying construction.5.Hold the gun.The gun is held by the palm, thumb, little finger and ring finger, and the middle finger and index finger pull the trigger. Some painters change the way of holding the gun from time to time when they work for a long time. Sometimes they only use their thumbs and palms with their little fingers, sometimes they use their ring fingers to hold the gun, and their middle and index fingers are used to pull the trigger. Electrostatic spraying equipment can alleviate fatigue and improve work efficiency.Maintenance of spray gun:Solution to spray gun failure:In the process of using the spray gun, some problems sometimes appear. Now, the phenomenon of the spray gun is analyzed in detail, and according to the phenomenon, the reason is analyzed to find out the solution.Tend Left or Right:Reason:1. The fan control hole on one side of the air cap is blocked2. Air cap damagedCountermeasures:1. Cleaning the atomizing cap2. Replace the atomizing capToo thick in the center of spray amplitude:Reason:1. The viscosity of the sprayed coating is too high2. Spraying pressure too low3. Nozzle diameter and thimble increase and decrease due to wearCountermeasures:1. Reduce paint viscosity2. Increase spraying pressure3. Replace nozzle setSpray split:Reason:1. Paint viscosity too low2. Too high spraying pressure3. The inner diameter of fan control hole is too large4. Insufficient paint5. Atomizing air passage blockedCountermeasures:1. Improve the viscosity of paint2. Reduce spraying pressure3. Replace nozzle set4. Add enough paint5. Clean the air passage of the spray gunJump gun:Reason:1. Nozzle not tightened or installed2. Gun needle seal kit loose3. Loose connecting nut of spray gun (lower spray gun)4. Insufficient paint in the pot5. Nozzle set damagedCountermeasures:1. Tighten the nozzle or clean and install the nozzle package2. Fastening thimble seal kit3. Tighten the connecting nut4. Supplementary coating5. Replace nozzle setUpper or lower weight of spray width:Reason:1. The air outlet of nozzle, thimble or air cap is blocked by sundries2. Damaged air cap or nozzleCountermeasures:1. Cleaning nozzle set2. Replace nozzle setPhenomenon: no paint or a small amount of paintReason:1. The air supplement hole of gun pot cover is blocked or the air cap and suction pipe are seriously blocked2. There is no paint in the pot3. Thimble travel too smallCountermeasures:1. Clean the air supply hole, air cap and suction pipe on the lid2. Supplementary coating3. Rotate the paint flow adjusting knob to increase the stroke of needle valveCoating leakage at nozzle:Reason:1. The sealing nut of thimble is too tight2. Foreign matter in nozzle port3. Nozzle and thimble are not matched or damaged4. Thimble return spring broken or not installedCountermeasures:1. Loosen the sealing nut of the thimble2. Clean the nozzle3. Replace nozzle set4. Replace the ejector return spring or install the upper ejector return springProduct Information:Item NO.KNBL-140CompassAluminium AlloyTeflon CoatedBarrelIron Nickel PlatingGun BodyAluminium AlloyTriggerIron Nickel PlatingHeadBrassRegulating ScrewImitation Gold CopperHandlePlastic Environmental ProtectionMOQ1500PCSMEAS64x34x27CMN.W./G.W.7.5/8.5KGSProduct Display:
