 A moment very popular in the paint is water-based ceramic coatings, ceramic coatings So in the end what is it? Here’s to say something about what is water-based ceramic coating standards and applications of water-based ceramic coating. What is a water-based ceramic coating?

Water-based ceramic coating belongs to the field of functional coatings and is a new type of water-based inorganic coatings. The standard of water-based ceramic coatings is based on nano-inorganic compounds as the main component and water as the dispersion. After coating, it is usually cured by low-temperature heating to form a coating film with properties similar to ceramics. Its raw materials are abundant, easy to mine, and cheap, which makes its cost lower than traditional coatings. Some of them use silane coupling agents and aluminum hydroxide colloidal ceramic coatings, which have many advantages such as high-temperature resistance, high hardness, non-flammable and smoke-free, super weather resistance, environmental protection and non-toxicity, rich colors, and easy coating. After various new improvements and enhancements, its superior performance and low cost have gradually replaced traditional coatings.
  Traditional organic coatings, etc., have a huge impact on the environment. Not only do the finished products often emit greenhouse gases to cause climate warming, but they also release toxic substances in the air, causing disease and death of people or animals and plants. It also consumes a lot of energy, does not meet China’s low-carbon concept, and produces various industrial sewage or toxic gases. After understanding what is the standard of water-based ceramic coatings, let ’s take a look at the application areas of water-based ceramic coatings:

  • cookware: metals cannot be used directly as cookware. Additional coatings are very important. Among them, ceramic coatings are more and more popular for their health and environmental protection and excellent performance. Testimonials. Especially when making a non-stick pan compared to ” Teflon” The viscosity is greater, it is not easy to fall off, and it is non-toxic and harmless. It is not easy to decompose at high temperatures for a long time.
  • Building materials: ceramic coatings are pure inorganic components, excellent weather resistance, and fire retardant. In addition, due to its breathability, it is resistant to pollution. It can be added with heat dissipation and heat insulation functions. It is an ideal material for building curtain walls.
  • Medical devices: ceramic coatings can impart a variety of properties, such as antibacterial properties, antistatic properties, and are inherently fire and flame retardant.
  • Natural gas, oil storage tanks: use The weather resistance and pollution resistance of ceramic coatings include artificial pollution and natural pollution.
  • Metal heating equipment: the multi-functionality of ceramic coatings can give the coatings anti-oxidation function and waterproof scale function. , With rich functionality.
  • Others: The metal-based ceramic coating material with good heat dissipation required on the circuit board in the electronic field, and the need for heat insulation, heat dissipation, and friction in key components in military equipment. Etc.

What are the characteristics of water-based ceramic coatings?

  1. Water-reducible paint refers to a paint formulated with a latex emulsion as a film-forming material so that the solvent-based resin is dissolved in an organic solvent, and then with the help of an emulsifier, the resin is dispersed in water to form an emulsion by strong mechanical stirring. For post-emulsification emulsion, the finished paint can be diluted with water during construction. Water-dispersible coatings mainly refer to coatings formulated with synthetic resin emulsions as film-forming materials.
  2. As the name implies, water-based paint is a water-based paint.
    For example, our interior and exterior wall coatings, metal coatings, and automotive coatings all have corresponding water-based coating products. It can be seen that water-based coatings have been widely used in many industries.
  3. The water-based coating has the advantages of saving resources, no pollution, good protection, and good corrosion resistance. However, the water-based paint has large water content, and if it does not pay attention to heat preservation during transportation, it is easy to freeze. And also because of water, it is easy to breed bacteria, so pay attention to anti-corrosion and mildew. Water-based coatings are mainly used for automotive coatings, metal coatings, and interior and exterior wall coatings. Water-based coatings have been widely used in many fields.
  4. Water-soluble paints are made of water-soluble resins as film-forming materials, represented by polyvinyl alcohol and various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. Wait. Water-reducible paint refers to a paint prepared by forming a latex emulsion into a film-forming material, which dissolves the solvent-based resin in an organic solvent, and then disperses the resin in water with strong mechanical agitation with the help of an emulsifier to form an emulsion. Emulsified emulsion, the paint made can be diluted with water during construction.

For ordinary people, the ceramic coating is a very unfamiliar concept, not as much as ceramics. In the face of such a relatively unknown idea, many people will have doubts about what is a ceramic coating, is it toxic, what are the characteristics of ceramic coatings and so on.

   The following is a brief introduction to ceramic coatings. As for the problem that people are worried about the toxicity of ceramic coatings, here, the editor can tell you that ceramic coatings are generally free of harmful substances, such as some kind of nanometers on the market. The composite ceramic coating can even achieve food grade certification. Relevant authorities have conducted safety tests on the chemical composition of dozens of ceramic coating materials, and have not detected a toxic substance or heavy metal. As long as the ceramic coatings produced by regular and qualified manufacturers are selected, the quality can be assured.

   So what are the characteristics of ceramic coatings? First of all, ceramic coatings can be said to change the application pattern of many coatings. Compared with traditional paints, they have a great lack of environmental protection. Ceramic coatings are environmentally friendly and non-toxic and are therefore favored and promoted by more people. Secondly, the ceramic coating has the characteristics of acid and alkali corrosion resistance, salt spray resistance, high-temperature resistance, wear resistance, anti-dirt, insulation, and so on. However, the quality of ceramic coatings on the market is uneven, so that the effect of use is also uneven, so when we choose ceramic coatings, it is best to use paints made by some well-known merchants.

High-temperature nano-ceramic coating

The high-temperature nano-ceramic coating is a new composite material technology, referred to as ceramic coatings (Ceramic Coatings) ceramic coating is composed of composite nano-materials of non-metallic compounds, metal oxides, rare earth oxides, on the surface of metal or non-metallic substrates, Spraying an ultra-fine nano-ceramic slurry with compressed air at normal temperature, often dried and solidified at room temperature, and sintered with the temperature of the furnace to form an ultra-thin ceramic coating film on the surface of the substrate and the substrate is tightly combined with the chemical bond A dense chemically inert protective film is formed between the high-temperature flue gas environment.

Wear-resistant ceramic coatings and applications

  Wear-resistant ceramic coating is the most popular and common application method of ceramic materials, based on the extremely high hardness and stability of ceramic materials. The wear-resistant ceramic coating has the characteristics of long service life, acid and alkali resistance, and no drop in energy index at high temperature.

The current wear-resistant coatings are made of multiple ceramic materials. The modified coating has better impact resistance, stronger corrosion resistance, and self-lubricating properties.

1. Aerospace-grade nano-composite ceramic technology, the effect is more stable.

2. Unique and mature nano-ceramic dispersion process technology, the dispersion is more uniform and stable; the interface treatment between the nano-micro particles is efficient and stable, ensuring the combination strength of the nano-composite ceramic coating and the substrate is better, the performance is more excellent and stable; the formula of the nano-composite ceramic is compounded To make the function of the nano-composite ceramic coating controllable.

3. The nano-composite ceramic coating exhibits a good micro-nano structure (nano-composite ceramic particles are intact to wrap micro-composite ceramic particles, and the gap of micro-composite ceramic particles is filled with nano-composite ceramic particles to form a dense coating. Nano-composite ceramic particles penetrate and fill the repair base On the surface of the material, it is easier to form a large number of stable nano-composite ceramics and the intermediate phase of the substrate) to ensure that the coating is stable and does not fall off.

The ceramic coating has the characteristics of high-temperature resistance, wear resistance, acid, and alkali corrosion resistance, salt spray resistance, anti-stain, insulation, and so on. The effect of ceramic coatings on the market is uneven, and the stability is also different. Beijing Nemo Company pays attention to research and development, hires new material experts with 20 years of actual combat experience to form a research and development technical team, conducts in-depth excavation of ceramic coatings, and develops unique functional nano-composite ceramic coatings.
