There are two methods of repairing inner tubes: hot repair and cold repair. The process of hot patching is as follows: roughen the area around the damaged area of the inner tube, blow off the filing chips, remove the paint cloth on the surface of the large repair rubber and stick it to the area damaged tire tube so that the puncture is in the center of the fire repair rubber, then align the tire repair clips. Install the fire repair glue and tighten the screw. The surface of the inner tube must be flat. Apply the heating agent to the. Fire repair glue. After 10-15 minutes or after the rubber repair shell has cooled, loosen the tire repair clamp and remove the fire repair glue. The rubber shell is cooled for another 5-10mm and the bond is tightened after inspection. The rep processCold aration is to roughen the damaged part of the inner tube (range 20^-30mm), remove the filing chips, and cut the tire repair tape into a round or oval shape (the size should be able to cover 20~20mm around the damaged part): 5mm), its edge should be in a slope shape, file the larger side of the tape. Apply rubber water evenly to both filed surfaces. Once the glue is slightly dry, glue them together and roll them with it. a roll. Or hammer it to make it stick flat and firmly. If the damage to the inner tube is significant, raw rubber can be used to repair it.
Apply special tire repair glue to the area with small holes and let it cool for a while to allow the benzene in the glue to evaporate. Peel off the plastic paper behind the inner tube patch, or find the same tubeair jet and use scissors to cut a piece the same size as the one sharpened in the previous step. Glue the inner tube patch flat to the glued inner tube. Press firmly and leave for a while until the glue is completely dry. Return the repaired area to the basin of tap water to see if there are still any air leaks. If there are no blisters, this proves that the tire repair was successful. Then check the other parts of the tube to make sure there are no other leaks, then put the tube back into the outer tire. Reinstall the tire. Then turn the bike over and inflate the inner tube. In this way, the bicycle inner tube is repaired.

There are two methods of repairing inner tubes: hot repair and cold repair. The hot patch process is as follows: reroughen the area around the damaged area of the inner tube, blow off the filing chips, remove the paint cloth on the surface of the large repair rubber and stick it on the damaged area of the inner tube so that the puncture is in the center of the fire repair rubber, then align the tire repair clips.

Peel off the plastic paper behind the inner tube patch, or find the same inner tube and use scissors. Cut a piece the same size as the one you ground in the previous step. Glue the inner tube patch flaton the glued inner tube. Press firmly and leave for a while until the glue is completely dry. Return the repaired area to the basin of tap water to see if there are still any air leaks. If there are no blisters, this proves that the tire repair was successful.

What happens with tire repair?
How to repair the wheel disc, hub and tire of an electric forklift:
1. Repairing the wheel disc of an electric forklift:
1) The holes for installing the bolts are as follows. When the tire is worn, the rounding error is greater than 1.5mm or the bearing surface of the ballsons of the tire is uneven, it can be repaired by lap welding.
2) Cracks between bolt holes or between large holes can be repaired by welding.
3) If there are any loose welds or rivets at the connection between the spokes and the rim, they must be re-welded or riveted again.
4) If there are cracks on the rim, they can be repaired by welding.
2. Electric forklift hub repair:
1) When the wear of the inner and outer bearing seat holes of the wheel hub is more than 0.05mm, it should be repaired by chrome plating.
2) If the oil seal seat hole is unevenly worn or has a dent of more than 0.15mm, it can be repaired by welding.
3) The circumferential surface in contact with the brake hub must be flat. If the circular runout of the hub axle is more than 0.1mm, it should be repaired by rotating.
4) LWhen the brake hub of the wheel hub has cracks, it can be beveled, welded and flattened.
5) When the internal thread of the bolt hole of the fixed half shaft is damaged, it can be re-drilled and tapped after lap welding.
6) When the circular runout of the end face contacting the half shaft flange is not more than 0.1mm, it should be corrected.
3. Electric forklift tire damage and repair:
Electric forklift tires include pneumatic and solid tires. Tire inflation pressure should meet the standards specified by the original manufacturer and should not be too high or too low. If it is too high, the elasticity of the tire will be reduced and the wire layer will be easily broken. Too low air pressure will cause serious tire deformation, increase temperature, cause degumming or breakage, and may also cause damage.cause movement of the outer tire on the rim and wear of the bead. In severe cases, the inner valve of the tire will be torn.
(1) Tire When the tire has cracks, holes, blisters, delamination and other damage, it should be repaired or renovated according to the specific situation. If there are continuous cracks around the tire casing, if the tread rubber has been polished and there are large holes, or if there are annular breaks in the tire layer carcass and separation of the ring assembly, they must be replaced.
(2) When small holes are detected in the inner tube, hot or cold repair can be carried out.
1) Hot repair: roughly file around the damaged area of the inner tube, apply fire repair glue to the damaged area, and make the hole right in the center of the repair glue , then align the repair clipsn tires Install the fire repair glue, tighten the screw, then turn on the heating agent on the fire repair glue. Wait 10 to 15 minutes before the bond is tight.
2) HealthGlue repair (cold repair): Roughly file the area around the inner tube tear, apply raw glue, wait until the glue surface is slightly dry, then apply a second glue. When the glue dries, attach the prepared raw rubber to the break. , then add Press and heat to 140-145°C, and keep warm for 10-20 minutes to vulcanize the raw rubber. After cooling, it can be tightly bound.
3) If the inner tube is bent or seriously cracked and cannot be repaired; if it is old and sticky and deteriorates if it is deformed or has excessive cracks, it can be scrapped and replaced with a new one; A.
1. Remove the pro tireblematics of the car.
2. Run the tire in soapy water to check for damage.
3. Use a grinding wheel to grind the damaged area.
4. Apply the tire patch to the damaged area.
5. Set the dryer to 110 degrees and dry the tire part for 3 to 6 minutes.
Detailed informationIt is used to repair side damage of car tires (semi-steel wire). In the past, car tires had to be scrapped if the side damage reached 1 cm.
Fire repair: It uses high temperature to fuse raw rubber to the tire wound to seal the wound.
Advantages, 1. Protect the environment. 2. High degree of wound integration. Disadvantages: The balance of the tire is affected and it can generally only be used for the rear wheels.
The hot repair method involves cutting a piece of rubber and gluing iton the flat tire, then pressing the tire on a machine to heat the rubber so that it melts and sticks to the tire.
