High purity Silica Oxide

Q: Is silica dioxide edible? What's the effect?: Can firmly absorb harmful bacteria, and coated, inhibit their reproduction, the gastrointestinal tract of Escherichia coli, Helicobacter pylori and other harmful bacteria killing rate is extremely high, and eventually excreted itBecause the light shale opal into the digestive tract of the body is not absorbed by the body, does not enter blood circulation, does not affect the gastrointestinal peristalsis and the digestion and absorption of food. More importantly, it can also help the repair and regeneration of damaged epithelial cells, normal balance of bacteria in the gastrointestinal tract, and has no toxic side effect, so it is very good the role of health care.

Q: Do you have food grade silicon dioxide?: Yes, we often have milk tea, the kind of powder bubble! Our company is also declaring food grade

Q: Why is silica in high purity water unstable?: Of course, structure and size of the R group of substances in solubility in water also. Such as alcohol: R - OH, with the increase of R group, part of the increase of non polar molecules, so with water (polar molecules) structure difference increases, so also decreased the solubility in water.

Q: Can the present nanometer silica dioxide replace the foreign silicon dioxide in China?: Domestic production enterprises also have production, compared with the chemical giants gap is mainly a variety of single, lack of stability! It's important to choose a good supplier. Domestic enterprises also need to continue their efforts, and can not allow foreign companies to use our resources to pollute our environment, but also to earn our profits.

Q: Silica gel and what reacts to produce silica?: As can be seen from the molecular formula, the silica gel is actually hydrated silica. Under intense heat, the reaction has a decomposition reaction to produce water and silica. This reaction equation

Q: What are the differences between micro powders, silica gel and silica?: In the pharmaceutical industry, most of the time, micro powder, silica gel and silica refer to the same thing, which can be interchanged most of the time in practical applications. According to the different preparation process can be divided into gas phase silica (colloidal silica) and silica, silica powder is fumed silica (colloidal silica) refers to the use of gas phase method prepared silica powder; silica is prepared by precipitation of silica gel (actually very fine).

Q: How can quartz sand and silica be distinguished?: Their database should have a contrast picture of quartz sand, depending on whether they're serious or not.It's better if you have a relationship with the customs and then declare it as you said. The symbolic inspection of the customs will be over.Customs inspection of goods in accordance with the declaration of the document is generally instrument scanning, encountered unclear, or suspected of goods, to open the box, open package inspection. After checking the machine, but also random checks, that is, unpacking, open the luggage, open the package to view. This is random, see a few finished, and not one by one to see. Accidental circumstances. It's very busy. I've seen the machine sweep it, too.

Q: What are the roles of silicon and silicon dioxide?: In order to adapt to the development of large-scale integrated circuits, monocrystalline silicon is developing toward large diameter, high purity, high uniformity and no defect. The maximum silicon diameter is 150mm, and the experimental high purity silicon is close to the theoretical limit purity.Solar cells are commonly used in silicon batteries. If the area of 1 square meters is covered with silicon solar cells, 100W power can be obtained. Monocrystalline silicon solar cells have stable performance, high conversion efficiency, small size and light weight. They are suitable for the power supply of space spacecraft. The United States -- large spacecraft space laboratory is equipped with 4 solar panels, which are composed of single crystal silicon solar cell 147840 8 square centimeters in size and arranged, power is about 12KW.

Q: Does the plant absorb the effective silicon in silicon calcium fertilizer or absorb silica?: Plants can absorb Portland, silica is a representation of numbers, how many can convert silicate; effective silicon refers to that part of the silicate can be absorbed by plants (the number of Portland and then converted into pure silicon).

Q: What are the main uses of silica?: Use of silicaSilica has a wide range of uses. Scarce crystals in nature can be important in the manufacture of the electronics industryParts, optical instruments and arts and crafts.
