The difference in the production process between microQuartz powder and microQuartz powder
Quartz powder is made of natural quartz (SiO2) or fused quartz (natural quartz after high temperature melting, cooling amorphous SiO2) by crushing, ball grinding (or vibration, air grinding), flotation, pickling purification, high purity water treatment, and other processes into the powder. Micro silica fume is also called silica fume or condensed silica fume and is also called silica fume. As the ferroalloy in smelting ferrosilicon and industrial silicon (silicon metal), the ore thermal furnace produces many highly volatile SiO2 and Si gas, gas emissions, and rapid air oxidation condensation precipitation. It is a by-product of sizeable industrial smelting; the whole process needs to be recycled with dust removal environmental protection equipment because the quality is relatively light, but it also needs to be encrypted with encryption equipment. In the transaction process, many manufacturers regard micro Quartz powder as micro Quartz powder. Still, because of the essential difference between the two, there is often a deviation in the transaction process. Hence, the product indicators provided by the manufacturers and the demand side of the index parameters are very different. From the appearance of Quartz powder and micro-Quartz powder is easy to distinguish; Quartz powder is pure, white, balanced particles, is a non-toxic, tasteless, pollution-free inorganic non-metallic material; According to the different silica raw materials, reducing agents or furnace conditions, the vast majority of micro-silica powder is gray or dark gray. In the process of formation, due to the effect of surface tension during the process of phase transformation, amorphous spherical particles of the amorphous phase are formed, and the surface is relatively smooth. Some of them are aggregates of several spherical particles stuck together. White micro-Quartz powder is rare and incorrectly positioned in the market. Shanghai Tiankai Special Materials Co., LTD has launched white micro-Quartz powder, which has been successfully used in composite fertilizers, pesticides (as adsorbent or silicon fertilizer production), coatings, paints (as a thickening agent and anti-settling agent), rubber (as reinforcing agent), plastics (as filling agent), unique ceramics, and can replace white carbon black. But the quantity is relatively limited.
