Bing Dundun is actually an ordinary plush panda doll, but compared with the common pure plush mascot, it has an extra silicone shell, and the Bing Dundun with the shell is more difficult to deal with in details. It is also the main reason why the production cycle of Bingdundun is longer than that of pure plush toys. However, consumers who get Bingdundun also have a trouble, the outer shell of Bingdundun will turn yellow. The friends who have used the transparent silicone protective case for their mobile phones must have a deep understanding. After a period of use, it will turn yellow and affect the appearance.
The shell of Bing Dun Dun is made of food-grade silica gel. The silica gel generally contains sulfide. After a long time, the sulfide will be oxidized and then turn yellow. With the increase of time, and after being irradiated by ultraviolet rays such as the sun and lights, the silicone products will slowly turn yellow and other aging phenomena. This is an irreversible process, but the yellowing does not affect its basic characteristics such as hardness, life and so on. If the transparent casing of the mobile phone turns yellow, you can consider replacing it with a new one. Does the outer casing of Bingdundun turn yellow? Just bear with it, you can't throw away what you have finally grabbed.
So what can be done to improve the change? Are there other better raw materials for silicone products to replace or improve? There are three main reasons for the successful breakthrough of the silicone case: first, the material is transparent; second, the hand feel is better; third, it can reach environmental protection food grade. Due to oxidation, it will inevitably turn yellow. Rubbing with alcohol is useless. Whether there is a better method or formula to use dimethyl or vinyl raw materials for production, this needs to be explored and developed by people of insight.
The conventional method of restoring the silicone coat is as follows:
1. First prepare a container, pour an appropriate amount of water, baking soda, toothpaste, alcohol and white vinegar into the container, and then stir it evenly. Soak the silicone sleeve in the container for about 30 minutes, and then wash it with soap again, so that the yellowed part of the silicone sleeve can be washed white, and the effect is better.
2. Use a piece of rubber to wipe the silicone sleeve, you can try to wipe it several times, so that the yellowed silicone sleeve will be rubbed by the rubber, and the original yellowed part will be wiped off, and the silicone sleeve will be whiter than before.
3. First squeeze the toothpaste on the silicone sleeve, then use the toothbrush to brush the silicone sleeve back and forth. There is no need to wet the silicone sleeve during the brushing process, just brush the inside and outside of the silicone sleeve, then sprinkle a layer of salt to continue brushing, and finally Wash it with clean water, and the silicone cover will turn white after a period of time.
In life, silicone case phone cases are more common, they look thinner and lighter, but they can protect people's phones well. However, the silicone sleeve will turn yellow after being used for a period of time, which is a common phenomenon. The above three methods can be used to quickly wash the yellowed silicone sleeve to a certain extent, and the effect is better. , but recovery is impossible!
