The repair method is actually very simple. Because the racket frame is hollow, high-strength adhesive is injected into the racket frame. After solidification, the glue becomes the high-strength skeleton of the lining frame, which not only bonds the cracks but also forms a solid skeleton, making this section of the racket frame a solid with higher strength than other parts.
Preparation tools:
1, buy a box of special adhesive for automobiles, also called double-tube adhesive, and configure it according to the instructions;
2, cotton is about half two;
3. Make a pencil lead-thick metal wire into a needle cone;
4. A calendar paper or hard paper;
5. Disposable 10ml syringe.
Specific steps:
1. Remove the plastic thread protector hole of the racket frame with the thread removed, and then twist it into paper with hard paper. Twist the paper into the same thickness as the grid, twist the paper into three grids on both sides of the crack, and leave a grid at the crack. Do not twist the paper.
2. After the paper is twisted, the fourth mesh on both sides of the crack can be filled with cotton balls, and the cotton balls should be filled little by little. Push the cotton ball into the eye with a real wire needle cone until the left and right spaces in the eye are filled with cotton balls until they can't be filled. The purpose of real cotton ball is to keep the glue before and after the crack when injecting glue.
3. After the adhesive is cured, remove the paper twist and thread it into the Yu 'an sheath. During this operation, the paper twist must be tightened and cotton must be filled to form a partition wall. Glue the inner eye of the remaining eye at the crack with white tape. Note that this eye must be glued firmly and can withstand certain pressure. The outer eye is used for injecting glue.
4. After these preparations are completed, the special adhesive for automobile can be prepared. Modulate according to the instructions. Slowly pour the prepared special glue into the syringe. Aim the syringe at the outer eye of the crack and inject the glue slowly and forcefully. If one injection is not satisfactory, you can inject it twice until it is full. When injecting glue, it is especially emphasized that it must be slow, so that the air in the frame can be exhausted, and the flow rate of glue solution is relatively slow.
5. After the glue is filled, put the glue injection hole of the racket upward in a safe place, and it will solidify after 24 hours. After solidification, the paper can be twisted and pulled out. If it can't be pulled out or can't be pulled out at all, you can use drilling tools to get through. For the scar on the appearance, you can use a combination brush to stick on this rubber brush or brush the protective layer the next day. If the outer protective layer is uneven, it can be polished with a file or sandpaper. Finally, a layer of paint with the same color can be painted, and the repair work is over. Put the plastic sheath in place and put on the rope again. After this repair, the racket can be used with confidence, and its strength is no less than that of the new racket.
This glue injection method is also suitable for weighting the beat, and the weighted position and weight can be selected at will. At the same time, it has the function of strengthening the beat. Therefore, you don't have to worry about the repair method of tennis racket emotional injury. The above methods are the repair methods of experienced professional players, and you can repair them according to this method.
