Q:Is the main component of the diamond silica?
The main chemical component of diamond is silica.Diamond is a commonly known, the main as is a crystal glass, is man-made crystal glass cutting into a faceted diamond jewelry accessories, such as material more economical, while the visual effect and dazzing feeling like diamonds. Therefore, it is very popular with people, the diamond is generally used in the design of mid-range jewelry.As a result of the current global man-made crystal glass manufacturing site, located in the north and south sides of the Rhine, it is also called Rhine stone. Produced in northern Austria Swarovski most do drill, referred to as Austria drill. It attracts sunshine very much, the gloss is very good, and the south bank is called Czech diamond. The absorption of sunlight is not enough, luster is not as good as Austrian drilling. Most of our products are Austrian drilling, and a few of them are Czech diamond.
Q:How to synthesize 100 nm sized silica?
TiO2 because of its activity is too large, easy to agglomerate, affect the performance of products, the commonly used methods are aqueous solution deposition drying method, sol-gel method, etc..
Q:Application characteristics of silicon dioxide shedding agent for shedding agent
The application of silica in the film when the opening agent added to allow customers to reduce the amount of amide slip agent, also can get excellent opening effect, static / dynamic friction reducing effect is obvious, the effects of additives on silica opening haze increased very little added in the film, the transparent degree is high, can effectively improve the end of yellowing the phenomenon of ".
Q:Colloidal silica; medical effect
There are two kinds of crystalline silica and amorphous silica in nature.
Q:The respective uses of silicon and silicon dioxide
Si, atomic number 14, relative atomic mass 28.0855, amorphous silicon and crystalline silicon two allotropes, which belongs to the periodic table for third cycles, IVA group metal elements. Silicon is also a very common element, but it rarely occurs in nature as a single substance. It is widely found in rocks, gravel, and dust in the form of complex silicates or silica.
Q:Can silica desiccant absorb alkaline gas?
Silica gel is a kind of high active adsorption material, belonging to the amorphous material, its molecular formula is mSiO2 nH2O; in addition to alkali, hydrofluoric acid does not react with any material, insoluble in water and any solvent, non-toxic, chemically stable.
Q:What is silica, please? What is there in life that is made of it? Why do I see silicon dioxide in potato chips?
Silica is an oxide of silicon and also an anhydride of silicic acidNatural silica (higher purity) is quartz and crystalThere are many kinds of silica in life, which can be said to be everywhere, such as sand, glass, ceramics, cement, jade and so on
Q:Use of silica dioxide in soybean milk powder
Add silica effect: make emulsification effect better.Food additive with silica has large specific surface area, so that it can play a role in the spacer between the powder particles, while promoting the free flow of powder material, its moisture absorption performance greatly, but also enhance the anti caking effect and adsorption.
Q:Calcium carbonate and silicon dioxide paper belts are dangerous wastes?
The only thing to note is that if there is calcium carbonate, silica powder bag, the best water wash then, or when wearing a mask or a lot of dust into the lungs can cause pneumoconiosis (and not components, dust inhaled into the lungs is the same problem)
Q:Difference between free silica and silicon dioxide
Silica (chemical formula: SiO2) is an acidic oxide hydrate, corresponding silicate (H2SiO3). Silicon dioxide is the most important compound of silicon. The natural silica present on the earth accounts for about 12% of the earth's crust quality. There are two major forms of crystalline silica, amorphous and amorphous.
