What is the reason for the smell of silicone phone case

Everyone knows that pure silicone raw materials are environmentally friendly, non-toxic and tasteless, but silicone products may have different flavors after silk screen printing, hand-feeling oil spraying, YM process, IMD process, laser engraving, glue glue, water paste and other processes. Will happen. This is very prominent on the silicone phone case. It can be seen that the generation of peculiar smell is most likely to occur in various processes after molding.


Usually, the process that causes the smell of the silicone phone case and produces the pungent smell is: silk screen and spray oil. Because the screen printing ink is composed of different chemical substances, it may have a pungent smell. After the screen printing is completed, the silicone phone case will have an obvious smell. However, it is not common for silicone mobile phone cases to have odors caused by silk screen printing. These are also normal phenomena, and the odor will be eliminated naturally after two or three days of exposure to natural ventilation.


Furthermore, after these processes, it is necessary to go through a tunnel oven high temperature secondary vulcanization. The purpose of this is not only to remove the taste, but also to volatilize and disperse the residual harmful substances as much as possible, and finally form a good product inspection and delivery.


However, some silicone phone cases factories are opportunistic, using inferior silicone raw materials or auxiliary materials, or the production process is not perfect, so that the products produced seriously do not meet the standards. The silicone mobile phone case is made of food-grade silicone material, which is much higher than ordinary silicone mobile phone cases in terms of raw materials and production processes. It takes enough time to remove volatile substances after molding.


Some manufacturers neglect the existence of this problem in pursuit of efficiency and cost reduction. As a result, the final mobile phone cases produced do not meet environmental protection standards. Generally, manufacturers producing such products are relatively small. Therefore, the editor tells everyone that you need to pay more attention when purchasing silicone products. Silicone products with serious odors cannot be purchased. Good quality silicone products have only a very slight odor, which can be automatically eliminated after a period of time. Even good quality silicone products will feel very flexible and comfortable to the touch, and the feel and texture are very authentic.

rufio costume

I \'ve been making Halloween costumes for my brother for years, and the challenge this year is Rufio in the movie Hook. Here you will find all the steps to make this outfit and I hope you like it! Supply: Black artificial leather, black canvas fabric, fusible interface, red fabric, black thread, black embroidery thread, sewing machine, wood beads, embroidery needle, scissors, iron, drill pin, colored pencil and paper. I first watched the movie Hook and outlined the idea of how the jacket should be constructed. Once I had a decent sketch and had a good idea of how to make it, I started making the pattern. Because the dress was made for my brother, I used him as a model and put a few pieces of scrap cloth on him with a pin to make the shape of the jacket. Once the shape is implemented and all the seams are marked, I transfer this design to the paper pattern. Before I used any of my good fabrics, I made a sample jacket for the test fit. Once it was decided to fit, I started cutting th...
