Over time, rust will inevitably appear on the outer shell of the solar water heater, which will affect the aesthetics of the water heater and also affect its service life. Therefore, prompt anti-rust treatment is very necessary.
First of all, we need to understand the reason why the solar water heater shell rusts. Generally speaking, this is because the metal material of the outer casing has been exposed to oxygen and moisture for a long time and an oxidation reaction has occurred, forming carbon dioxide. rust. During rust treatment, it is necessary to prevent rust from continuing to spread and corrode the water heater, and restore its original appearance and shell protection function.
Two methods of treating rust are shown below:
1. Manual cleaning
The first step is to brush off the rust with worm paperre or a copper brush. From large areas to small areas, brush the obviously rusted areas first. Use even force when brushing and use a soft brush to clean off any remaining rust. After cleaning, rinse with soapy water and clean water.
2. Chemical cleaning
Chemical cleaning can not only completely remove rust, but also prevent and inhibit rust. There are many cleaning products to choose from in the market, but you also need to choose according to the actual situation. Under normal circumstances, we can choose to use vinegar, pour the vinegar into a clean spray bottle, and then spray it evenly on the rust stains. Once the vinegar solution penetrates the rusty surface, use a soft brush to remove all rust stains.
Whether manual cleaning or chi cleaningmic, after cleaning is completed, the surface of the housing should be thoroughly cleaned and sealed with paint to protect the surface and prevent rusting again. In addition, we can also pay attention to protection during use to reduce the damage caused to the solar water heater by the external environment.
Generally, it is very normal for the shell of the solar water heater to rust, but we should treat the rust in time to protect the shell and extend the life of the water heater.
