Industrial kilns, furnaces, and boilers usually burn high temperatures above 1000°C. The furnace structural materials are mainly refractory materials such as high-brick bricks, clay bricks, castables, ceramic fibers, etc. They are both the structure of the furnace body. Materials, thermal insulation materials, also participate in the radiative heat exchange process. Their thermal radiation properties and thermal insulation properties determine the thermal efficiency of the furnace, which makes it difficult to achieve a solid structure, high thermal insulation and high reflectivity for a single material. Claim. After thousands of tests and proof of specific furnace use, BSD-109 high-temperature far-infrared radiation coating is adopted, infrared reflection of the coating is applied, heat exchange in the furnace is improved, temperature field intensity and uniformity in the furnace are improved, and fuel combustion is more fully performed. , To increase the thermal efficiency, greatly improve the thermal efficiency of the refractories, reduce energy consumption, save energy and extend the service life of the furnace liner.

Kilns usually consist of four parts: kiln chamber, combustion equipment, ventilation equipment, and transportation equipment. The kiln chamber is the main working area of ​​the kiln, and the temperature is relatively high, generally above 800°C. If gas is used as fuel, the temperature can reach as high as 1400°C. The thermal insulation of the combustion chamber requires a lot of attention.
The traditional thermal insulation materials are heat-insulating bricks and fire-retardant bricks, but their thermal conductivity (insulating bricks: 0.12-0.21 W/m•K; refractory bricks: 0.12-0.21 W/m•K) determines that very thick insulation is required. The layer directly reduces the working space of the kiln chamber and increases the volume of the kiln chamber. For the rotary kiln, the increase in the weight of the kiln body increases the extra consumption of electric energy. Now the new environmentally-friendly ceramic high-temperature thermal insulation coating has begun to show its strength in this field with its ultra-low thermal conductivity (0.03W/m•K).
Far-infrared high-temperature radiation coating product description: When the heating furnace working temperature is 700 °C, the heat transfer is mainly based on radiation (more than 90%). Using this product, the emissivity of the furnace body at high temperature rises from 0.35 to 0.88. Absorption of heat on the surface of the body is greatly increased. The far-infrared radiation coating has an emissivity of 96% at a high temperature, thereby significantly increasing the temperature of the heating furnace body. The strong radiation material contained in the paint radiates far-infrared waves with strong penetrating power at high temperature, so that the molecules of the heated object absorb waves to generate energy level transitions, absorb energy uniformly and heat, reduce heating time, and fully save energy. Features: Safe and pollution-free, with remarkable energy-saving effect, high temperature resistance, excellent chemical stability, resistance to various kinds of atmosphere corrosion, excellent heat radiation performance, radiation strength and high replacement rate, good anti-erosion performance, full protection of the lining surface, high temperature Keep the surface smooth and smooth. Typical applications: refractory linings for high-temperature heating devices such as various processing furnaces, forging furnaces, boiler locomotives, steel rolling reheating furnaces, reforming hydrogenation furnaces, cracking furnaces, etc. Technical performance index: Far infrared radiation coating product code BSD-109, method Emissivity (2.5-20um) ≥ 0.90, anti-washout (m/s) ≥ 50, package type: colloidal material drum.
Far-infrared high-temperature radiation coatings are based on the study of spectra, heat reflection and absorption laws and radiation laws of various substances, and fully synergistic effects of absorption, reflection, and radiation. They are made of nanomaterials modified by special processes, and cured. A structural coating with thermal high radiation energy is formed. BSD high-temperature radiation energy-saving coatings are divided into two types, 150-600°C and 600-1700°C. Temperature-resistant 150-600°C high-temperature radiation energy-saving coating, also called radiation cooling cooling coating, is a kind of coating with high radiant heat. The coating can emit the heat brushed on the object in the form of 4-13.5μm wavelength, infrared electromagnetic wave The emissivity can reach 90%, and the surface temperature of the object can be greatly reduced. The energy efficiency of radiation cooling can reach over 30%. Double speed Radiant cooling cooling coating at the same time radiation heat, but also has a very good self-cleaning, anti-corrosion, waterproof, anti-acid and other characteristics.
Far-infrared high-temperature radiation coating can be applied to various high-temperature industrial furnaces and boilers that do not directly contact with the melt, such as industrial boilers, metallurgical hot blast furnaces, rolling steel heating furnaces, soaking furnaces, boilers, etc., and paint the far-infrared coating on the lining. The inner wall improves the blackness of the lining, improves the thermal energy absorption and infrared radiation of the coating, improves the heat exchange in the furnace, increases the temperature field strength and uniformity in the furnace, and makes the fuel combustion more fully, thereby increasing the thermal efficiency, reducing energy consumption, saving energy and protection Furnace lining, extending lining life, environmental protection and other purposes.

High-temperature resistant far-infrared radiation coating is a special functional energy-saving coating that is resistant to high temperature, strong emissivity, corrosion resistance, and high wear resistance. It is developed by Ningbo Times Express Co., Ltd. using nanotechnology organic-inorganic IPN technology. Industrial kilns, furnaces, and boilers usually burn high temperatures above 1000°C. The furnace structural materials are mainly refractory materials such as high bricks, clay bricks, castables, ceramic fibers, etc. They are both structural materials of the furnace body. , It is also a thermal insulation material, and also participates in the radiative heat exchange process. Their thermal radiation performance and thermal insulation performance determine the thermal efficiency of the kiln, which makes it difficult for a single material to achieve strong structural, high thermal insulation and high reflectivity requirements. .
