Take A Small Amount Of Silica Gel Desiccant Into The Water

take a small amount of Silica Gel Desiccant into the water
Ordinary life often encountered after eating snacks desiccant, in fact, this is a kind of food desiccant, called Silica Gel Desiccant. Silica Gel Desiccant transparent ball particles, its own non-toxic environmental protection, not the body to absorb, suitable for food packaging moisture. In addition to this for food packaging, the use of Silica Gel Desiccant can also be used repeatedly, can be used for albums, books, packets, tea and other products moisture preservation. How does the Silica Gel Desiccant check its effect?
Check the Silica Gel Desiccant whether there are several ways to effect:
1, take a small amount of Silica Gel Desiccant and a small amount of discoloration of silicone sealed together to observe the discoloration of silica gel discoloration speed, slow color change is that the product of low water content. This method of detection is also more scientific, but only that the detection of Silica Gel Desiccant moisture content is more than the color of silica gel. In addition, the manufacturers produced by the discoloration of silica gel, due to the proportion of the proportion of raw materials added, will also cause its discoloration of silica gel itself is different color change. So, we can not completely convince this detection method.
2, take a small amount of Silica Gel Desiccant into the water, observe the intensity of the explosion of water: explosion fast, strong explosion effect, that the product is low water content, good adsorption.
3, take a small amount of Silica Gel Desiccant on the hands of grip, feel whether it is fever. If the fever is good, it is good. Silica Gel Desiccant in the absorption of water will release a certain amount of heat, but only artificially feel, the way is completely incorrect.
4, take a small amount of Silica Gel Desiccant weighing placed on the outdoor 2 days, in the weighing, calculate the difference between the two weighing results. The difference is that the product is good. The principle of this method is correct, but because the external environment is constantly changing, so this method is detected by the results can not be completely convinced.
Food desiccant often see a transparent beads of desiccant, this is actually Silica Gel Desiccant, Silica Gel Desiccant is environmentally friendly non-toxic, silicone is the only FDA certified by the United States, with drugs, food direct contact with the use of Of the desiccant. Why does the Silica Gel Desiccant bounce up with water?
In the desiccant learned, first of all we look at the main component of Silica Gel Desiccant silica gel, silica gel itself, the possibility of chemical reaction is very low, because: silica gel adsorption performance is high, good thermal stability, chemical stability, Of the mechanical strength.
So why the Silica Gel Desiccant water bounce up why there are two reasons:
First, the pinhole of silica gel is particularly high, encountered water when the water too fast, resulting in violent expansion of the volume of Silica Gel Desiccant. So lead to Silica Gel Desiccant after the water will bounce up.
Second, silica gel mixed with other desiccant, other substances may encounter water will react to exothermic chemicals. So put into the water will produce a lot of heat. So lead to Silica Gel Desiccant after the water will bounce up.
Silica Gel Desiccant water absorption will lead to violent jump, mainly intense water will make the silicone ball expansion, access to momentum, and thus bounced up.
