Coating knowledge: the difference between inorganic coating and organic coating

Core tip: inorganic coating is one of many inorganic materials Even in terms of coatings, inorganic coatings only occupy a small proportion, but they should be highly valued by people First of all, 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 Secondly, compared with some organic coating base materials, the production and use of inorganic coating base materials have little environmental pollution Most of the products are based on water as the dispersion medium, without adverse environmental and health effects Three is Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: inorganic coating is one of many inorganic materials Even in terms of coatings, inorganic coatings only occupy a small proportion, but they should be highly valued by people First of all, 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 have little environmental pollution Most of the products are based on 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 same alkaline cement and lime sand and other base applications Moreover, they can react with the lime in these base materials to produce calcium silicate crystals, which can form an integral part with the base, so their adhesion is particularly good General situation of development: inorganic coating has not been clearly defined According to people's habit, it generally refers to a kind of coating whose main base material is inorganic material Here, the meaning of the main base material is that some inorganic base materials (such as silica sol) must be added with a certain amount of organic base material to make up for the lack of its performance when preparing coating Since the development of architectural coatings in China in the 1970s, the base materials for the production of inorganic architectural coatings in China are mainly silica sol and silicate solution, while the coating varieties mainly include two-component potassium silicate outer wall Coating, composite organic base silica sol external wall coating, inorganic mould resistant coating, inorganic fire retardant coating, inorganic insulation coating, inorganic anti condensation coating, cement styrene acrylic emulsion exterior wall coating and acid modified sodium silicate coating Some kinds of inorganic architectural coatings have been widely used For example, the two-component potassium silicate exterior wall coating was once the main type of exterior wall coating in many areas in the 1980s and early 1990s Some walls of the early coating of this kind of coating are still basically intact after nearly 10 years of wind and rain erosion and natural aging The composite exterior wall coating made of cold solidity of silica sol and styrene acrylic emulsion or pure acrylic emulsion is not complex because of the complex process and stable storage of paint, especially the dense coating, good stain resistance and overcoming the brittleness defect of inorganic architectural paint The construction performance and decorative effect are similar to that of latex paint of the same grade, so it has been recognized from its application till now In order to be a kind of coating with better technical and economic performance These two kinds of coatings are widely used in the whole country with different commodity names In addition to flat coating, it can also be made into thick coating of different styles, such as multi-layer coating, sand wall coating, etc it can also be made into light ceiling sound-absorbing coating, etc The inorganic coatings based on acid modified sodium silicate solution are lower in cost and retain some other properties of inorganic coatings However, due to construction and decoration effects, although they are also applied, the quantity and scope of the inorganic coatings are much less than those of the first two, while the amount of inorganic coatings made from water mud and styrene acrylic emulsion is less Functional inorganic building coatings, i.e anti mildew coating, fire-proof coating, thermal insulation coating and anti condensation coating, are widely used in the field of inorganic fire-proof coating, such as LG steel structure fire-proof and thermal insulation coating (non expansion type), e-60 expansion type inorganic fire-proof coating, etc.; secondly, inorganic anti mildew coating is also widely used due to its inherent excellent anti mildew performance Although inorganic anti condensation coating and inorganic thermal insulation coating have good performance, they are seldom used due to their small consumption 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,
