    Core tip: Introduction: Silica sol coating is one of the most promising environmental protection building coatings Silica sol is a dispersion in water with SiO2 as the basic unit, its molecular form is H2SiO3, the micelle particles are fine, and the particle size range is generally 5-40 nm SiO2 has a high activity and is easy to bond the powder particles in the coating when it is used for rubber separation Therefore, one of the most outstanding advantages of SiO2 used in the coating is its non solubility and good water resistance When silica sol is used alone, there are often fatal defects such as cracks and internal micropores in the film formed by curing at room temperature, so it is rarely used alone Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Introduction: silica sol coating is one of the most promising environmental protection building coatings Silica sol is a dispersion in water with SiO2 as the basic unit, its molecular form is H2SiO3, the micelle particles are fine, and the particle size range is generally 5-40 nm SiO2 has a high activity and is easy to bond the powder particles in the coating when it is used for rubber separation Therefore, one of the most outstanding advantages of SiO2 used in the coating is its non solubility and good water resistance When sol-gel sol-gel is used alone, there are often fatal defects such as cracks and internal micropores in curing films at room temperature Therefore, few coatings are used alone to prepare coatings Organic inorganic composite coatings are often prepared by adding organic polymer emulsion Modified silica sol coating is based on silica sol coating, in order to get more excellent performance Production: formula design and preparation process the coating is mainly modified by adding water-soluble melamine and polyol to silica sol, and other additives are added to obtain the interior and exterior wall coating with excellent weather resistance and water resistance Technical appearance of coating: Construction: coating with wall applicator or spraying with color sand paint spraying machine Application: used as interior and exterior wall coating of general building Safety: human skin contact shall be minimized in coating production to prevent operators from inhaling from respiratory tract Ventilation equipment shall be installed in coating workshop Volatilization of organic solvent shall be prevented as much as possible during coating production All storage tanks containing volatile raw materials, semi-finished products or finished products shall be sealed as much as possible Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
