What glue can be used to repair the water leakage at the welding place of the copper radiator?

Radiator is a kind of heating radiator, which has a unique charm as a heating device for modern life. If your radiator is still under warranty, you can contact the manufacturer to replace the new radiator, if the cast iron radiator you use is not within the warranty period, it is recommended to replace the new radiator (steel radiator, copper-aluminum composite radiator) in the current heating market.

It can be bonded with Jinshida soft rubber, and the sealing effect is very good.

It's just that the kind of small sand hole cracks can use YH-106 metal casting glue, and the casting glue glue contains metal powder, which is very hard after curing, almost reaching the hardness of iron. Then this glue is waterproof, resistant to high temperature 150 degrees, and resistant to pressure.

1. What glue is used to repair the leakage of the radiator?

When the leakage of the radiator is relatively slight, epoxy resin glue or other glue-like and mud-like glue can be used, and the liquid glue can not be repaired, because after the liquid glue is cured, the entire crack or small hole of the radiator cannot be blocked, and the liquid glue will have the phenomenon of bonding dislocation, and the glue is solidified, or can not solve the phenomenon of radiator leakage. When the leakage of the radiator is serious, it is recommended to replace the radiator.

2. How to maintain the radiator?

1. During the heating period, in order to prevent the inner wall of the radiator and pipe from being oxidized and corroded, the heating company will add chemicals to the heating water to neutralize the ions in the water and adjust the pH. Heating users can not take this kind of heating water, one is unsafe to use, not good for the body and the environment, and the other is if the heating water is privately released, resulting in the lack of water in the system, the heating company will inject a large amount of water into the system, carrying a lot of oxygen into the pipe, making the radiator easy to be corroded.

2. Use the exhaust valve on the radiator to remove the air in the system in time to prevent oxygen from coming into contact with the inner wall of the radiator and increasing the probability of being corroded by oxidation. Generally, the heating system needs to be commissioned when it is first run, and the user needs to open the exhaust valve of each radiator to vent the air accumulated in the radiator, or open the exhaust valve installed in the gas collection tank installed on the top of the system to exhaust the air. After the exhaust is completed, the valve should not be opened and closed at will to prevent it from being wrung out.

3. After the heating is over, do not discharge the water in the system, and carry out "full water maintenance" on the radiators and pipes, especially for steel radiators. Full water maintenance is to use the water in the radiators and pipes to effectively isolate the air, reduce the risk of erosion of the radiators and heating pipes, and can prolong the service life of the heating system.

4. Do not pile up sundries at the upper end or in front of the radiator, on the one hand, the pressure bearing capacity of the radiator is limited, and it is easy to be damaged once it exceeds the limit, causing safety accidents; On the other hand, a certain amount of heat dissipation space should be maintained near the radiator as much as possible, otherwise it will affect the heat dissipation effect of the radiator.

Radiator leakage is caused by long-term use, internal rust, generally there are small holes, you can use a small wood, sharpen it with a knife, and then use a small hammer to nail it into to plug the leakage, if it really can't be blocked, you can only replace it with a new radiator, and it can't be blocked with glue.

Clean with gauze paper: no oil. Water: Then glue it with AB glue and you're done!

AB glue is another name for two-liquid mixed hardening rubber, one liquid is the glue, one liquid is the hardener, the two liquids can be hardened by mixing, and it is not necessary to rely on temperature to harden and mature, so it is a kind of hardening glue at room temperature, and it is sometimes used to make models. Generally used in industry.

AB adhesive is the name of a two-component adhesive. AB glue with acrylic, epoxy, polyurethane and other components is commercially available. When used in the factory, in order to distinguish it from the conventional large cans (1 kg and 2 kg sets), epoxy resin, the abbreviation of the toothpaste tube is AB glue (the eye-catching name on the box).
