The invention discloses a method for synthetically utilizing by-product in polycrystalline silicon producing course, vaporizing the by-product, preparing highly pure nano silicon dioxide with low chlorine content by high temperature hydrolyzation reaction, where the prepared silicon dioxde powder has primary grain size of 7-40 nm, specific surface area of 100-400 m2 / g, and pH value of 3.6-4.5, and silicon dioxide content above 99.8%, and can be widely applied to organic silicon, rubber, plastics, paint, and electronics, and other fields, playing the role in reinforcing, thickening, thixotropic property, antisettling, etc.

The invention relates to a filling slurry for a glass substrate, a preparation method thereof and a mixing device, wherein the slurry comprises 75-80% of alumina, 8-10% of water, 4-6% of polyacrylic acid ammonia, and carboxymethyl Cellulose 9-10%; when preparing, adjust the pH value of the water to 10-11 with ammonia water, then add alumina, polyacrylic acid ammonia and carboxymethyl cellulose in sequence, and stir for 24-30 hours to obtain; active in the mixing device The position setting of the roller shaft and the driving roller, the driven roller shaft and the driven roller, and the radius of the driving roller shaft and the driven roller shaft are the same, and the radius of the driving roller and the driven roller is the same. Under the action of the limit device, the driving roller The shaft and the driven roller shaft are set in parallel and have the same height, which can ensure that under the action of the motor, the first conveyor belt and the second conveyor belt, the driving roller shaft can drive the driven roller shaft to rotate, and the material barrel and the driving roller shaft can be connected by inherent friction. The rollers and driven rollers rotate synchronously to meet the time requirement of 24-30 hours for mixing materials.

The invention relates to an anti-microbial strengthening water-based paint additive and a preparing method thereof. The anti-microbial strengthening water-based paint additive is prepared from, by mass, 68.9-89.88% of deionized water, 5-15% of needle-like inorganic material crystal whisker, 5-15% of nano-zinc oxide anti-microbial agent, 0.01-0.05% of water-based dispersing agent, 0.01-0.05% of water-based coupling agent and 0.1-1% of anti-settling wetting agent. The anti-microbial strengthening water-based paint additive is characterized in that special preparation and dispersion methods are adopted for the needle-like inorganic material crystal whisker and the nano-zinc oxide anti-microbial agent, the problems of big difference between nanoparticles and particle aggregation are well solved, and the processed nano-zinc oxide has the advantages that size distribution is narrow, grain size is small and released anion concentration is large. By adding the anti-microbial strengthening water-based paint additive to a water-based paint product in the proportion of 5-15%, the product can have high anti-microbial property, film-forming property, scratch resistance and settling resistance.

The invention provides a low-VOC (Volatile Organic Compound) environment-friendly concrete interface treating agent. The low-VOC environmental-friendly concrete interface treating agent is prepared by cross-linking reaction of sepiolite with grafted end vinyl and carboxylhyperbranched polyester, vinyl acetate-vinyl copolymer emulsion, polyethyleneimine and trimethylolpropane-tri(3-aziridinyl propionate). The low-VOC environmental-friendly concrete interface treating agent provided by the invention has the advantages that the VOC is lower, the viscosity is good, and the problems of high volatilization and environmental pollution in the traditional interface treating agent are effectively solved.

The invention provides a low-volatility environment-friendly building interior concrete interface treating agent. The low-volatility environment-friendly building interior concrete interface treating agent is prepared by carrying out a crosslinking reaction among attapulgite grafted with a maleic acid-terminated ester group and vinyl hyperbranched polyester, a vinyl acetate-ethylene copolymer emulsion, polyethyleneimine and trimethylolpropane-tris[3-(2-methylaziridinyl)propionate]. The low-volatility environment-friendly building interior concrete interface treating agent has low VOC (volatile organic compounds) content and good viscosity, and effectively solves the problems that the conventional interface treating agent is high in volatility and is not environmentally friendly.
