It is a special energy-saving coating with high temperature resistance, strong emissivity, corrosion resistance and high wear resistance. The coating is applied on the inner wall of the kiln. Through the infrared radiation of the coating coating, the heat exchange in the furnace is improved, the temperature field intensity and uniformity in the furnace are increased, and the fuel combustion is more complete, so as to increase the thermal efficiency, greatly improve the thermal efficiency of refractory materials, reduce energy consumption, save energy and extend the service life of the furnace lining, with high energy saving rate. High temperature far-infrared radiation coating is based on synthetic resin emulsion, and is configured with fillers, high-quality pigments and various additives, and far-infrared radiation minerals. After application, it can form a thin layer of furnace wall coating with a smooth surface.
It has good weather resistance and water resistance. It has good leveling, dries quickly, is odorless, has good color retention and scrub resistance, and has good air permeability after drying. It has stable color and is not easy to fade. It can be rubbed and sprayed, and is easy to construct. It is environmentally friendly and pollution-free. It has the functions of inhibiting bacteria and inflammation, promoting and improving blood circulation, promoting metabolism, balancing the body's pH, and improving human immunity.

Functions and uses of infrared high emissivity energy-saving coatings
Infrared high emissivity energy-saving coatings are directly applied to the surface of refractory materials (refractory bricks, refractory fibers, refractory castables) and metal parts such as furnace tubes in the kiln lining, which can improve the uniformity of furnace temperature, increase the energy utilization and production efficiency of kilns and boilers, protect kiln linings, and extend the service life of industrial furnaces. This product can be widely used in various types of heating furnaces, heat treatment furnaces, ceramic and refractory firing kilns and other thermal equipment; as well as high-temperature protection of high-pressure steam pipes, heat exchangers, petroleum cracking equipment, engines and other components.
Infrared high emissivity energy-saving coatings are the result of repeated research and development with the introduction of the latest technology from home and abroad. Scientific, accurate and applicable formulas can be selected according to various furnace types, different furnace wall materials, different operating temperatures and different heating objects. Infrared high emissivity energy-saving coatings have the characteristics of high temperature resistance, high emissivity and strong adhesion. They are widely used in machinery, metallurgy, electronics, chemicals, textiles, building materials, food, ceramics, leather, papermaking and other industries. They are used in various dense furnaces, boilers, heat treatment furnaces, baking rooms, etc. with temperatures ranging from 150-1850℃ and using coal, oil, gas and electricity as energy. With high thermal efficiency, good slag resistance and water resistance, they have a unique effect on accelerating the heating rate, reducing energy consumption, extending the service life of kilns and improving product quality. Infrared high emissivity energy-saving coatings are the only most ideal energy-saving materials in China. The main technical indicators have reached or exceeded national standards and reached international advanced levels.

Instructions
1,Before coating, use emery cloth, steel brush, dry rag and other tools to clean the oil, ash and other residues on the surface of the coated substrate.
2,The infrared high emissivity energy-saving paint needs to be stirred evenly before use.
3,Apply the paint on the surface of the substrate by spraying or brushing at room temperature, apply 2-3 times, and the energy-saving effect is best.
4,After coating, let it dry naturally and the furnace can be put into operation. Note that the heating rate from room temperature to 400℃ should not exceed 100℃/hour
