The joint method of toasted blue packing steel belt

a) Hot melt lap type. It adopts heating methods such as electric welding, mechanical high-frequency oscillation welding and ultrasonic welding. The surface layer of the plastic belt is heated and melted, and the melting surfaces of the two belt ends are overlapped, and kept under a certain pressure for a certain period of time. After the melting surface is condensed , The way to bond the plastic tape joint. This joint method is suitable for polypropylene plastic tape, because if the polypropylene plastic tape is mechanically fixed with an iron buckle, its strength is only 50% of the base material, and the adhesive connection is not suitable.
　　b) Metal button type. This method is to first use the one-way work of the tensioner ratchet to tighten the belt, then place an iron buckle at the joint, and then use clamps to make the iron buckle wrap the two layers of belts, and make the side teeth of the iron buckle concave and convex The teeth are shaped so that you can bite the strap and prevent it from loosening. The iron buckle is usually made of galvanized iron sheet, and the iron buckle of the suitable specification should be selected according to the type of strapping belt during operation.
　　c) Ligation type. This joint method uses soft plastic rope, hemp rope, etc. as the binding material, and the joint is tied into a slip knot. This joint method is both firm and beautiful, and easy to untie.
