Application of plastic flame spraying

1, restore the size of wear parts Various shaft parts installed rolling bearing parts, bearing housing housing box, governor thrust disc wear, the wear parts can be sprayed with nylon or plastic cover to restore the wear parts size of.
2, anti-wear materials for bearings in a variety of sliding bearings and sliding surface with nylon coating layer, can effectively improve the bearing performance. At the same time, due to the good flexibility of nylon, the stress concentration can be reduced and the load can be evenly distributed so as to reduce the vibration and reduce the noise. In practical work, with the dynamic fit parts, often restore the wear size and spray friction layer together, so that the spray layer at the same time play two roles. Such as the repair of crankshaft bearings, camshaft bushings, pump bearings, such as machine rails.
3, repair corrosion, cavitation (cavitation) parts Engine cylinder liner, water jacket and other long-term contact with water, especially in the coastal areas, seawater salt content is high, the phenomenon of corrosion and pitting corrosion is very serious. Is the general pump impeller and pump housing, cavitation occurs in the work of the phenomenon. Spraying plastic overlays on these parts extends the life of the part. In addition, spraying plastic coverings into hull, tillage (roll) vessel inflows also gives good corrosion protection.
4, as a seal of the oil pump housing seal, oil pump shaft seal parts, pump valve plate distribution and a variety of conical, cylindrical and planar valve sealing surface, can be sprayed nylon or plastic. Spraying nylon or plastic, do not have to grind, just turning, you can meet the technical requirements.
5, sticky repair damaged parts For the flow of iron in the cast iron hole or loose texture caused by oil leakage, leakage of metal box, the body can be sprayed in the defective parts, used to plug holes and holes, such as for the trachea, pipe , Plug the tubing.
6, insulation coating large rectifier, welding machine, start the motor wire is relatively thick, insulation damage, you can also use spray coating to repair. For some parts require insulation of the workpiece, plastic spraying is more suitable. In addition, plastic spraying in the high-frequency, high pressure situations, can also be applied.
7, shock absorption, sound-absorbing materials Vibrating feed mechanism work noise, poor working environment, the operator is also very easy to fatigue. For this purpose, the coating can be sprayed onto the area where the feed mechanism contacts the workpiece, which significantly reduces the noise and improves the working conditions.
8, decorative, anti-rust layer All kinds of machine tools, ships, vehicles handle, handle and other manipulation parts, usually with the plating method to solve the decoration, rust problem.
9, insulation materials Some pneumatic tools, operators in contact with compressed air circulation pipes will feel very cold, especially in winter, the operator will even be frostbite. If the parts in contact with the hand spray nylon or plastic coating, you can greatly reduce the hazards of freezing on the operator.
10, paper industry shaft and sleeve size, size guide wheel. Can be applied plastic spraying process.
11, oil, acid, minus, salt and chemical tank size cylinder, plastic spraying process can be used.
12, Coastal equipment corrosion, mining equipment corrosion, corrosion of structural parts, etc., can be used plastic spraying process.
