Densified Silica Fumes

Q: Does marble dust contain silica?: But not all of the so-called anti-dust masks has a good protective effect, but also has anti-dust masks of various grades and ranks. The protective effect of the respirator depends on 2 aspects: the tightness of the mask and the face and the protective efficiency of the filtering cotton on the superfine dust.

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: Crystal silicon and silicon dioxide belong to atoms or molecular materials?: In atomic crystals, there is no independent small molecule, but only the whole crystal is considered as a macromolecule. The covalent bond between the atoms interact with each other is very strong, want to break these keys and make the crystal melting must consume a lot of energy, so the crystal atoms generally have a high melting point, boiling point and hardness, not conductive normally, poor conductor is hot. It does not conduct electricity when melted, but semiconductor silicon can conduct electricity conditionally.

Q: Use of silica dioxide in soybean milk powder: Silica is a naturally occurring mineral, and many vitamin supplements sold in the market contain this mineral. In general, silica is used as an anti caking agent and, if ingested in combination with a normal balanced diet, helps to restore joint and cartilage damage, such as arthritis. In addition, it also benefits the blood vessel wall.

Q: What materials do you have instead of silica powder?: According to the guide light transmittance is divided into several. The most typical is silica, but the brightness of the silica has not been ideal for addition to the resin. There are many developed new conductive powder, haze higher, higher brightness. Better than silica.

Q: How much acid does silica use to become mesoporous silica?: We used 30% hydrofluoric acid to etch the sample in an ultrasonic environment. In this case, it is necessary to seal the container, because the concentration of 30% hydrofluoric acid is relatively high, and the volatility is stronger. You can have a try

Q: Is silica and white carbon a product?: And white carbon is a special silica. Belong to silica category.Fumed silica is prepared by gas phase method, precipitation method, gel method, etc..Silica includes white carbon black.

Q: How can quartz sand and silica be distinguished?: Quartz sand is a very important and widely used mineral. It is forbidden to be exported in many countries, including our countrySilicon dioxide is a compound of oxygen and silicon. It is the main component of quartz, crystal, quartz sand, ceramics, glass and so on.It's purely chemical. Neither toxic nor burning nor corrosive and not subject to controlled substances.

Q: Why is crystal silicon used in general?: Plating can be regarded as the upgrade of coating.

Q: How to solve the gel problem between silicone oil and white carbon?: Carbon black is the floorboard of white powder X- ray of amorphous silica and silicate products, mainly refers to the precipitated silica, fumed silica, ultrafine silica gel and gel, including powder synthetic aluminium silicate and calcium silicate etc..
