Molecular sieves refer to a class of substances with uniform micropores and the pore size is equivalent to the general molecular size. Commonly used molecular sieves are crystalline silicates or aluminosilicates, which are connected by oxygen bridges to form pores and cavities of molecular size (usually 0.3~2 nm). . In addition, phosphoaluminate molecular sieves have been discovered, and the framework elements (such as silicon, aluminum, and phosphorus) of molecular sieves can also be replaced by other elements (heteroelements, such as iron, boron, copper, manganese, etc.).
It is estimated that the total installed capacity of solar thermal power generation in the world will reach 42GW in 2020 and 200GW in 2030. According to the construction cost of US$2500 per kilowatt, the industry can reach 3.2 trillion yuan! According to the data of the Ministry of Housing and Urban-Rural Development of China, the per capita housing in the city is 30 square meters and the rural area is 33.6 square meters, the total housing is about 45 billion square meters.
Shijiazhuang Youthchem Electronic Technology Co., Ltd. is a national high-tech enterprise focusing on the research and development of high-purity silica nanomaterials. Its main products include high-purity and ultra-high-purity silica sol, high-purity organic silica sol, etc. The company was established in 2012 and is located in Shijiazhuang National High-tech Zone. It has achieved more than 70% market share in the high-purity silica sol market in the photovoltaic field. The company attaches great importance to the cooperation of production, education and research with various universities. Most of the company's core R&D teams have master's degree or above. At present, the company has obtained more than 10 authorized invention and utility model patents, and several patents are in the process of application. At present, we can adjust the particle size and distribution, morphology, density, surface charge, solid content, pH value, etc. of colloidal silica according to customer needs. At the same time, in addition to water-based systems, we can also use company-specific Surface modification methods to obtain silica nano dispersions dispersed in various organic solvents. The company has high ambitions and is determined to be the most professional service provider in the field of high-purity silica nanomaterials.
Everyone knows that silica sol is not toxic. It is not listed as a hazardous chemical, but its additives may be included. The chemical formula of silica sol is mSiO2·nH2O, and its composition is amorphous silica particles, water and Small amounts of stabilizers (such as Na+, K+, NH4+) workshop staff should wear protective clothing, protective glasses and other safety facilities to protect the skin during production. If you accidentally touch the skin, just wash it off with water.
Nano particles are used in coatings to obtain coatings with anti-radiation, aging resistance and high peel strength or with some special functions, called nano composite coatings. According to the fineness of the coating, nanocomposite coatings can be subdivided into nano-modified coatings and nano-structured coatings.
