Q:Can silica and ammonium sulfate be used in combination?
The magnetic energy provided by the permanent magnetic material is W=1/2 (BH) V, and the V in the formula is the volume of the permanent magnet. In order to obtain the required magnetic energy with the minimum magnetic volume V, the maximum (BH) product should be made so that the permanent magnetic material working on the demagnetization curve should be at its operating point (BdHd) = (BH) max. This point can be obtained by the hysteresis loop of the permanent magnet in the figure method. At this point, there should be Bd/, Hd=, Br/, Hc. Among them, Bd is working point, magnetic induction intensity, Hd is working point, magnetic field is strong, aromatic, Br is residual magnetism of permanent magnetic material, Hc is coercive force.
Q:What's the effect of silica in the new health care product?
The total amount of silica in the human body is about 7 grams. Animal tissues and plant ashes contain a small amount of this chemical.
Q:What are the states of silicon dioxide?
The moon quartz mineral was first discovered in a few pieces of broken granite, in petrosilex also filled a lot of cristobalite minerals from the analysis show that the micro structure and composition of the quartz is actually changing over from cristobalite. Later in the coarse crystalline moon crushed granite is also found in quartz minerals, according to the analysis results, the isotopes of these minerals is about 4 billion 100 million years, the formation of crystals in the deep environment, indicating that these silica is not formed during crystal formation in magmatite.
Q:What are the characteristics of silicon dioxide?
Natural earth diatomite is amorphous silica, is the remains of low water plants diatom, white solid or powder, porous, light and soft solid, strong adsorption
Q:How to make crystals from silicon dioxide
Find some salts you can get, warm up, make saturated solutions, and then try to find a glass container that is as airtight as possible. Just wait until it crystallizes. You can also try to dissolve different salts together, hoping to have a pleasant surprise.
Q:Lead-acid battery plate production and paste adding silica have what use?
Improve the conductivity of active substances and improve the porosity of active substances, adsorption of excess surface material, improve the ability to charge acceptance
Q:What is the role of fumed silica in coatings?
Rheology is the important properties of the coating, it directly affects the appearance of coatings, the performance of the construction performance and storage stability, and the requirements of different coating systems on rheological additives are also different. For oily system, most are rheological agent plays the role of hydrogen bond formation. The unmodified fumed silica containing aggregates a, which is an isolated, free two undisturbed is united, each other to form hydrogen bond bonded hydrogen bonding in the oil system, very easy to form a three-dimensional network structure, the structure of mechanical force effect will be damaged, so that the viscosity decreased, coating restore good fluidity; when the shear the force is eliminated, the three-dimensional structure will recover, viscosity increased. In a completely non polar liquid, only a fraction of a second viscosity recovery time; in a polar liquid, recovery time is longer, depending on the gas phase silica And the dispersion degree of concentration, storage and application performance of this feature gives oily coating is very good, especially thick conformal coatings, which can ensure the coating has good fluidity in the construction of the shear, a thickness of the construction, but also can ensure the film is usually in the construction process, due to the edge of the coating the solvent leads to faster, the surface tension is not uniform, easy to paint to the edge of mobile, and mobile network can prevent coating silica effectively and the formation of thick, while also preventing coating during the curing process of the sagging phenomenon, the coated layer is uniform. At the same time, fumed silica due to the formation of hydrogen bonds and improve the low shear viscosity in the system, and thus play a thickening effect. Therefore, fumed silica is widely used in the oil system.
Q:What is the difference between silica and reactive silica?
Silica dioxide plays an important role in daily life, production and scientific research, but sometimes it can cause harm to human body.
Q:How much is the content of silica in cement?
The main ingredients of cement are calcium silicate two, silicic acid three calcium, and aluminium acid three calcium, respectively2CaO *SiO2,3CaO*SiO2,3CaO*Al2O3Come on, SiO2%=17.9%Not counting impurities,
Q:How does silica play an anti sinking action?What is its network structure?
Fumed silica is four to silicon chloride hydrolysis in an oxyhydrogen flame. It is small in size, large surface area, with silanol groups on the surface. These interactions with adjacent silanol radical gas phase silica particles and the formation of hydrogen bonds, as shown in figure.
