Inorganic coating is a kind of coating with inorganic material as the main film-forming material, which is the abbreviation of all inorganic mineral coating. Because of its high performance, it is widely used in construction, painting and other fields of daily life.
Inorganic coating is an inorganic polymer coating composed of inorganic polymer, dispersed activated metal, metal oxide nano material and rare earth ultra-fine powder. It can react with iron atom on the surface of steel structure rapidly, and generate an inorganic polymer anticorrosive coating with physical and chemical double protection. It has no pollution to the environment and long service life through the solid combination of chemical bond and matrix, The anti-corrosion performance has reached the international advanced level, and it is a high-tech replacement product in line with environmental protection requirements.
Organic coatings have been purchased by consumers for their good decoration, low price and variety diversity. However, due to the raw materials from coal, oil, natural gas and other chemical resources, it is easy to produce a large number of harmful substances in the production process, causing serious environmental pollution problems, and difficult to meet people's demand for safety and health. The organic coating forms a film on the wall surface and the outer wall, while the pressure generated by air and water is affected by temperature and moves on the airtight inner and outer wall surface, constantly acting on the coating. After a period of time, the wall coating will appear hollowing, blistering or even peeling off, so the inorganic coating came into being in line with the trend of environmental protection home furnishings in this era.
What is the essential difference between organic coatings and inorganic coatings?
First, the base materials of inorganic coatings are often directly from the nature, so the source is very rich. For example, silica sol, silicate solution and other coating base materials, whose main raw materials come from quartz ore, are extremely rich in nature.
Second, compared with some organic coating materials, the production and use of inorganic coating materials have little environmental pollution, most of the products are water as the dispersion medium, without adverse environmental and health effects.
Third, the aging resistance and some physical and chemical properties of inorganic coatings are difficult to achieve for most organic coatings with the same production cost, so they have better technical and economic properties.
Fourth, most of the inorganic coatings are alkaline, which is more suitable for the application of the same alkaline cement and lime sand base, and can react with the lime in these base materials to generate calcium silicate crystal, which can form an integral part with the base, so its adhesion is particularly good.
