Stainless steel shower hose is an essential bathroom accessory in many households, but many people have found that it is easy to rust during use. Why is it so easy to rust? What methods can prevent rusting? Below, the editor will provide a science popularization for everyone.
The appearance of the stainless steel shower hose is made of stainless steel material. Stainless steel reacts with oxygen in the atmosphere, forming an oxide film on the surface of the material.
After the formation of iron oxide on the surface of steel, it will continue to oxidize under the action of oxygen in the air, and over time, the rust will expand and form pores.
For this reason, manufacturers choose to use corrosion-resistant steel. In order to further enhance its corrosion resistance, electroplating is applied to the surface of the corrosion-resistant steel. However, this does not mean that the electroplated steel will not rust or corrode. Electroplating is only a thin film on the surface, and this protection is limited. Once the protective layer is damaged, the surface of the steel will begin to rust.
Generally speaking, the corrosion resistance of stainless steel materials is directly related to the chromium content in the material. If the chromium content in the material is 10.5%, it can greatly increase the corrosion resistance of the steel, but it does not mean that the higher the chromium content, the higher the corrosion resistance of the steel. According to research, although the chromium content in the steel increases, the overall corrosion resistance of the steel does not increase significantly.
This is mainly because when chromium is used for alloying treatment of steel, the type of surface oxide changes, making the surface similar to the oxide formed on the surface of pure chromium metal. The tightly adhered chromium rich oxide provides a protective effect on the surface of steel, effectively preventing steel oxidation.
However, this layer of oxide is relatively thin and can still retain the natural luster of the stainless steel surface, thus preserving the characteristics of the stainless steel material. However, once this layer of oxide is damaged, the surface of the stainless steel below will be exposed to the air. However, after the stainless steel surface reacts with the atmosphere, this layer of oxide will undergo a self repairing process, forming a passivation film again to protect the steel.
However, if the oxide layer on the surface of stainless steel is completely damaged, the protective effect will no longer be effective, and the surface of stainless steel will react chemically with oxygen, water, salt, etc. in the atmosphere, leading to rusting.
How to prevent stainless steel shower hoses from rusting? Some people always find ways to remove the rust marks on their home hoses when they find them rusty, but even after treatment, the surface gloss is not as good as when they first bought them. In fact, paying attention to the following points during normal use can effectively prevent rusting.
1. Be waterproof. The bathroom is a place with a high water consumption in the house, and it is inevitable that there will be a large number of water droplets and stains during use. Dampness can cause the hoses to rust. Therefore, it is necessary to do waterproofing in daily life. After showering, timely mopping and ventilation should be carried out, and attention should be paid to the unobstructed drainage system to reduce water accumulation.
2. When choosing hoses, you can choose hoses that have undergone surface chrome plating treatment. Chromium plated hoses have much stronger corrosion resistance than hoses that have not undergone chrome plating treatment, so they are less likely to rust. Pay attention to checking whether the coating is even and complete.
In addition, stainless steel shower hoses can also be sent to specialized repair shops for maintenance and treatment. During use, avoid splashing acidic substances onto the surface of the hose. If slight rust is found on the surface, it should be treated promptly to avoid the expansion of the rust surface.
