Silica Gel Desiccant Water Why Bounce Up?

Silica Gel Desiccant water why bounce up?
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. Silica Gel Desiccant if the water bounce, it proves that its moisture absorption capacity is relatively strong, good quality.
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. 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, gain momentum, and thus bounced up.
Such desiccants are non-toxic, Silica Gel Desiccant is a physical adsorption desiccant rather than chemical reaction desiccant desiccant, and silicone is FDA only recognized directly with food and drug contact desiccant raw materials. Compared to other desiccants, Silica Gel Desiccant used in food moisture is relatively safe. In addition to the above factors, Silica Gel Desiccant also has a strong ability to absorb, adsorption performance, the Silica Gel Desiccant all into the water, it will not melt. With non-toxic, tasteless, non-corrosive, non-polluting characteristics, even if the food will not be absorbed by the body, do not worry.
We all know that food packaging has a desiccant, the kind of transparent ball particles is Silica Gel Desiccant, in general, food packaging is mostly used in such desiccant. What are the characteristics and advantages of Silica Gel Desiccant it? Xiaobian to share with you.

1, Silica Gel Desiccant insoluble in water and any solvent.
Non-toxic and tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any substance. Various types of silica gel because of its different manufacturing methods to form a different microporous structure. The chemical structure and physical structure of silica gel, it determines that it has many other similar materials difficult to replace the characteristics of high adsorption performance, good thermal stability, chemical stability, a higher mechanical strength.
2, Silica Gel Desiccant safety performance
Silica Gel Desiccant is the main component of silica, chemical stability, not burning. Silicone is a kind of amorphous silica, should control the workshop dust content is not more than 10 mg / cubic meter, need to strengthen the exhaust, wear mask when operating. Silicone has a strong ability to absorb, the human skin can produce a dry effect, therefore, the operation should wear a uniform. If the silicone into the eyes, need a lot of water rinse, and as soon as possible to find a doctor for treatment.
3, save and packaging
Silica Gel Desiccant has a strong hygroscopic capacity and should therefore be stored in a dry place. There should be a shelf between the packaging and the ground. Packaging materials are steel drums, paper drums, cardboard boxes, plastic bottles, polyethylene plastic composite bags, flexible container bags, and so on. Silica Gel Desiccant specific packaging specifications see classification Product description, transport process should avoid rain, moisture and sun exposure.
