What causes the aging heat of silicone products Wireless silicone aging Wireless silicone aging Increasing the temperature can cause the thermal cracking or thermal crosslinking of silicone products. But the basic function of heat is activation. Improve the oxygen diffusion rate and activation oxidation reaction wireless silicone aging , so as to accelerate the rubber oxidation reaction speed wireless silicone aging , which is a common aging phenomenonThermal oxygen aging.
The aging of the floating oil seal silicone ring is not without traces, but due to complex chemical reactions and storage conditions. Understanding and following the correct storage and use methods is the key to delaying aging and extending service life. Only in this way, the floating oil seal can continue to provide a reliable seal under various working conditions to ensure the normal operation of the equipment.
Yes. According to the inquiry Weishun silicone official website. Silica gel used for a long time will react with oxygen, which will lead to color change, hardening and loss of elastic aging on the surface of silica gel. So the silicone time is long wireless siliconeLine cleaning. With wind oil essence, cotton swab dipped in wind oil essence, wipe in the stained place, and then rinse with water and put in a cool ventilated place to dry. With xylene, soak in the silicone area, wipe the silicone soaked in xylene with a paper towel, and finally wipe off with a rag.
2, if the yellow because of tea, coffee or other stains, can be used to remove stains or bleach treatment. If it is caused by the above usage time, you can consider another one. Generally, mobile phone silicone products turn yellow, only the surface layer turns yellow, mobile phone stores can buy organic solvents, or use the type of oil cleanser to scrub two or three times,Remove the layer of silicone from the surface.
3, for the silicone shell that is difficult to clean, you can try the oil essence, dip the oil essence with a makeup swab in the stain, gently smear the sassafras wipe clean, and finally rinse with water, dry in the shade.
4, the method of whitening is as follows: use toothpaste or detergent to clean the surface of silicone products, and then rinse with water, dry can become white. The use of alcohol or acetone and other organic solvents to scrub can also be white, but pay attention to the amount of use and use methods to avoid damage to silicone products. By adding curing agent with anti-yellow properties, the mold temperature and curing time of silicone products are controlledOther methods, from the source to delay the aging of silicone products yellowing.
5, it can be used for at least 10 years, and up to 100 years in unconventional cases. Often used at high temperatures or for a long time in a high temperature environment, it will accelerate the oxidation environment of silicone products and aging. Therefore, when we use silicone products, we should try to avoid long-term use in the environment of high temperature and pressure, chemicals and ozone, so that we can effectively alleviate the aging phenomenon of silicone products, thereby improving the service life of silicone products.
6, you can use general common solvents (such as: day that water, white electric oil, etc.) to eraseThere you go. Stain removal liquid or bleach is suitable for tea, coffee or other stains organic solvents or alcohol is suitable for the phone case for a long time and yellowing Note: But these methods will not completely solve the problem of yellowing, and will damage the mobile phone silicone shell, so that the phone case becomes gray and dull.
Yes. According to the inquiry Weishun silicone official website. Silica gel used for a long time will react with oxygen, which will lead to color change, hardening and loss of elastic aging on the surface of silica gel.Therefore, silica gel will age for a long time. Silica gel is a kind of highly active adsorption material, which belongs to amorphous substance.
Yes, high temperature or in a complex environment will also age, hardness increases, strength decreases, elongation becomes shorter, etc. No, as long as it is not rubber, Vaseline is a long chain alkane, that is, a polymer hydrocarbon, with fat solubility (Vaseline is a colorless, odorless, non-fluorescent transparent oil liquid obtained by deep refining, without any additives, moisture and mechanical impurities.
Silica gel is easily blackened and moldy by water stains, dirt, and air oxidation. Silicone aging: due to useThe time and high temperature or in a complex environment will also cause some parameters to change, such as increased hardness, reduced strength, shorter elongation and so on; Features can be identified by color such as yellowing than normal. Generally speaking, silica gel can be divided into two categories of organic silica gel and inorganic silica gel according to its properties and components.
For friends who buy silicone products, the service life and aging rate of silicone materials have not been accurately verified, and there will be doubts about the safety of this silicone product. In fact, generally our common silicone products, usually no problem in five years of frequent use, but different methods of use alsoWill make a difference in its service life. The following small series introduces the service life and duration of some commonly used silicone products.
The reason for the aging of silicone products is the role of heat, and increasing the temperature can cause the thermal cracking or thermal crosslinking of silicone products. But the basic function of heat is activation. Increasing the oxygen diffusion rate and activation oxidation reaction, thereby accelerating the rubber oxidation reaction rate, which is a universal aging phenomenon - hot oxygen aging.
