Silicone material has the characteristics of softness, falling resistance and wear resistance. So the protective covers of many products are made of silica gel. For example, silicone bottle cover, mobile phone cover and so on. Silicone protective sleeve can reduce the wear speed of product surface and slow down the direct impact of articles.
Silicone cover includes silicone mobile phone cover, silicone flat cover, silicone cup cover and so on, which can be seen everywhere in life. With the promotion of smart phones, various styles of mobile phone cases have also flocked. Among them, silicone mobile phone cases are deeply loved by everyone because of their soft texture, comfortable feel, wear resistance and fall resistance, and diversified styles. However, after a long time of using the silicone mobile phone cover, it will appear yellowing due to sweat and oil stains. It looks very uncomfortable. Then, what is the reason for the yellowing of the silicone mobile phone cover?
1. It is possible that the raw material of silicone cover itself belongs to low-end industrial silicone, which fails to meet the standard after being made into finished products, resulting in yellowing.
2. There is no anti yellowing agent in the raw material of silicone sleeve, so the color turns yellow when it is pressed and vulcanized at high temperature in the final process.
3. If the transparent silicone material is often in a high temperature environment and exposed to the sun, it will also cause yellowing.
1. Rinse with clean water:
This is a common method. If there is grease on the silicone sleeve, it is recommended to apply some soapy water, then wipe off the stain with a soft cloth, and then rinse with water. Finally, dry the silicone cover with a paper towel or soft cloth and put it in a cool and ventilated place to dry.
2. With an eraser
The eraser is very easy to use. Besides wiping the pen, it also has a great cleaning effect on other objects. It can also be used on the silicone cover, especially for the model with frosted effect on the body. Just wipe it with a simple rubber, and the dirt can be easily cleaned out.
3. Alcohol wiping method
As we all know, alcohol has a very strong decontamination ability and is volatile. It recovers to a dry state in a very short time after wiping. It is not as easy as water to penetrate into the machine, which is likely to cause a short circuit of power supply. Just wipe it with a paper towel. It can also disinfect.
