The reason of wpc sandwich metal boards rust
People see the wpc sandwich siding metal boards patterns or designs on woodwork when building decoration products will give a person a kind of beautiful feeling and style of many let us to choose, and it is also convenient to construction.But after installation for a period of time, you will find the surface of the wpc sandwich metal boards will be a layer of rust .In turn,it will affect the building on the surface of the beautiful,So what are the causes of rust on the surface of the product?
1, Waterproof wpc sandwich metal boards is born intergranular corrosion: this material that does not contain titanium and niobium has the tendency of intergranular corrosion. Intergranular corrosion can be reduced by adding titanium and niobium together with stable treatment. A high alloy steel resistant to corrosion in air or chemically corrosive media.
2. No solution treatment: alloying elements are not dissolved into the product, resulting in low alloy content in the matrix and poor corrosion resistance. So we should pay attention to this aspect of protection measures.
3. Chloride ions exist in the use environment of lightweight wpc sandwich metal boards: chloride ions are widely existed, such as salt, sweat, seawater and so on. In the presence of chloride ions, corrosion is rapid, even more than ordinary mild steel. So there are requirements for the use of the product environment, and need to often wipe, remove dust, keep clean and dry.
The above is the reason for the rust on the surface of the wpc sandwich metal boards. In fact, it is not difficult to see that most of the reasons are still because of the daily lack of take care of, so don't ignore anything after the construction, which will only make the surface of the product produce more substances, and then affect the service life and use effect of the product.So after the installation, we should pay more attention to the above points in the beginning of use to reduce the probability of rust.
