Densified Silica Fumes

Q: How to synthesize 100 nm sized silica?: Water spray drying method is often used in inorganic coated with nano titanium dioxide, which is deposited on the TiO2 surface with a layer of oxide or hydrous metal oxides, to reduce its chemical activity, improve the weatherability of ridicule. Therefore, adding silica can solve the above shortcomings.

Q: What is the difference between crystalline silicon and silica?: Silicon is found in nature in large amounts of silicate ores and quartz ores. The earth is mainly composed of the mineral world, abundance in the crust is 27.7%, in all of the elements in the second, with the formation of silica SiO2 oxygen and silicon most elements in the crust, the crust accounted for 87% of the total mass. The difference between monocrystalline silicon and polycrystalline silicon is that when the molten silicon is solidified, the silicon atoms are arranged in a number of nuclei with diamond lattices, and if these nuclei grow into crystalline grains with the same orientation, then monocrystalline silicon is formed. If these nuclei grow into crystalline faces with different orientations, then polycrystalline silicon is formed.

Q: Does the dust produced in the manufacture of abrasive wheels contain silica?: 3, mask materials are silicone, plastic and so on, silicone material is relatively soft and comfortable, low facial pressure.4, for dust and oily particles, masks are divided into anti oil (soot, oil mist, dust, smoke, fog, micro-organisms, expressed in KP), dust (dust, smoke, fog, micro-organisms). For dust prevention, the protection level has KN100, KN95 and KN90 three grades, because this work environment pollutant diversity, harm to people more, I suggest the choice of KN100 grade.

Q: What are the factors that affect the thickness of silicon dioxide films?: The die temperature distribution is not uniform, high and low, so that the film thickness of the uneven blow;

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: Silica, diamond, graphite, sulfur, phosphorus, and the number of covalent bonds in the cause of red phosphorus: The diamond structure is similar to that of silica. Each carbon atom has four covalent bonds, and the space regular tetrahedron is arranged periodically. A total of 1 x 4 / 2=2mol covalent bond.

Q: Is silica and silica powder the same thing?: Especially silicon powder by crushing, milling (or vibration, jet mill), flotation, acid purification, water treatment and other multi-channel processing of the powder, the physical crystal configuration specific, and therefore has certain properties. This is like graphite and diamond chemical formula is C, but they are caused by different crystal structures nature is also different; gold, gold bullion and pull thin properties are also different.

Q: What are silicon and silicon dioxide often used for?: You can also make the quartz crystal jewelry, such as SWAROVSKI; there is another form of silica, amorphous silica, which is a very fine powder and carbon black, because similar effects, color is white, the industry called silica as reinforcing material. The chemical is also used as a chromatographic stationary phase with a certain particle size of silica.

Q: What are the physical properties of silicon dioxide?: Silica also called silica, chemical formula SiO. There are two kinds of crystalline silica and amorphous silica in nature. Crystalline silica is divided into three kinds: quartz, scale quartz and square quartz because of their different crystal structures.

Q: The food additive has "silica dioxide", can you eat it?: You can eat, don't worry. Our company produces food grade silica dioxide, food hygiene production license, in line with the requirements of the Ministry of health, is edible. As we usually eat flour, tea, coffee and many other food grade silicon dioxide, that is, food anti caking agent.
