The secret that silica gel desiccant can also be turned into treasure
We will see desiccant bags in the package of many drugs and snacks, and there are generally such cautions as "do not eat" and "please discard" printed on them. In fact, there are two kinds of desiccants commonly used now, namely lime desiccant and silica gel desiccant. The price of lime desiccant is low, and in recent years, there have been many news about children accidentally eating or playing with water explosion. From the safety point of view, silica gel desiccant is more suitable.
However, should we really follow the notes on the package "please discard"?
Experts verify that silica gel desiccant actually has many wonderful uses, and it can be "turned into treasure" in just a few steps.
Chemical experts point out that when planting flowers and trees, pour out the silica gel desiccant and mix it into the soil, it can be used as fertilizer - in fact, there has been silica gel fertilizer sold in the market for a long time. The main component of silica gel, silicone, has the effect of promoting photosynthesis in plants.
The natural desiccant that was circulating on the Internet before to save the phone from falling into the water is rice. In fact, if we keep some silica gel desiccant, its drying and absorbing efficacy is far better than rice. Put the silica gel desiccant in the container, turn off the phone in water, and disassemble the battery and other parts, put it into the silica gel desiccant, after 24 hours, generally speaking, the problem is not big.
The same use of silica gel desiccant water absorption function, but also can solve the camera lens fogging problem. This kind of problem is generally recommended by experts to buy a drying box, but from the cost aspect, silica gel desiccant is actually a better choice. After removing the camera's battery and memory card, put the camera into the food box with silica gel desiccant particles and set it aside for a while, which should prevent the lens from condensing dew. Second, although underwater cameras usually have a special waterproof case, but a little moisture or water infiltration will lead to the camera "scrap". Beforehand in the waterproof box into two or three packets of silica gel desiccant, can play a certain preventive effect.
The silica gel desiccant is insoluble in water and any solvent, tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. The interior of silica gel desiccant is extremely fine pore mesh structure, these pores can absorb water and retain the water through its physical attraction, aviation parts, computer devices, electronic products, leather products, medicine, food and other industries. Even if the desiccant is fully immersed in water, it will not soften or liquefy. It has the characteristics of tasteless, non-corrosive and non-polluting, so it can be in direct contact with any items.
Experts remind that the effect of small doses of desiccant in food and medicine packaging is limited, and if you really need to protect the items from moisture, you should still buy a certain amount of desiccant specifically. The desiccant can be used in a variety of ways.
