5results about How to "Improve anti-icing performance" patented technology

The present application relates to the technical field of composite functional materials, in particular to a spinel-type composite photothermal super-hydrophobic coating, a preparation method thereof and application thereof in ice prevention and removal, wherein the preparation method of the spinel-type composite photothermal super-hydrophobic coating first prepares spinel-type CuFeMnO4 material with micro-nano structure through co-precipitation and high-temperature heat treatment of copper salt, iron salt and manganese salt, and then performs surface hydrophobic modification on the spinel-type CuFeMnO4 material by using palm wax. By combining the excellent photothermal conversion performance of the spinel-type CuFeMnO4 material with the low surface energy characteristics of palm wax, the synergistic effect of high-efficiency photothermal conversion and super-hydrophobic performance is realized, so that the coating layer formed by the prepared spinel-type composite photothermal super-hydrophobic coating has excellent super-hydrophobicity, durability and environmental adaptability and can achieve good ice prevention and removal effect. In addition, the preparation method has the advantages of simple process, low cost and environmental friendliness.

This utility model relates to the field of anti-icing technology, specifically a plate heat exchanger structure for a laser chiller with air-blowing anti-icing function. It includes a laser chiller, an air-blowing component located outside the inlet of the chiller, and a recovery component located outside the outlet. The air-blowing component includes a fixed plate, with gears connected to the outer wall of the fixed plate. After use, the gas blows out any remaining purified water from the chiller. The blown-out purified water is blocked by a baffle and falls into a water storage tank, preventing the risk of freezing and explosion from the source, thus improving the chiller's safety and avoiding water waste. It also ensures no water residue remains inside the chiller, further enhancing the anti-icing effect. The design of the first and second hydraulic cylinders eliminates the need for manual operation, ensuring that the blowing action is completed after each shutdown, improving operational convenience and reliability.

This invention relates to a firefighter's protective suit that combines anti-icing and warmth retention properties. It consists of a jacket and trousers. The jacket collar material, from the outside in, comprises an outer layer I, a waterproof and breathable layer I, a heat insulation layer I, an outer woven fabric layer I, and a warmth-retaining fabric layer I. The jacket hem material, from the outside in, comprises an outer layer II, a waterproof and breathable layer II, a heat insulation layer II, a comfort layer woven fabric III, and a warmth-retaining fabric layer II. The other parts of the jacket material, from the outside in, comprise an outer layer III, a waterproof and breathable layer III, a heat insulation layer III, and a comfort layer woven fabric V. The jacket cuffs are thickened ribbed cuffs. The trousers material, from the outside in, comprises an outer layer IV, a waterproof and breathable layer IV, a heat insulation layer IV, and a comfort layer woven fabric VII. This invention focuses on the warmth retention of the comfort layer and the anti-icing design of the outer layer of the firefighter's protective suit, achieving both warmth retention and anti-icing properties, ensuring the comfort of firefighters during movement and maintaining operational efficiency.

The invention relates to the field of coating compositions, and particularly discloses an anti-icing self-cleaning coating material for a tower drum of a wind driven generator as well as a preparation method and application of the anti-icing self-cleaning coating material. The anti-icing self-cleaning coating material comprises a bottom coating material and a surface coating material, the bottom coating material contains fluorosilane, amino silane, ethyl acetate, butanone, filler, fluorocarbon resin and an isocyanate curing agent, the filler comprises alpha-Fe2O3 modified mesoporous SiO2 particles and hydroxylated boron nitride, and the surface coating material comprises fluorine modified SiO2 particles and acetone. The anti-icing self-cleaning coating material can achieve a good protection effect on the tower drum of the wind driven generator, the water contact angle of the surface of the coating is larger than 155 degrees, the water rolling angle is smaller than 5 degrees, the ice adhesion strength is smaller than 30 kPa, the water contact angle is still larger than 150 degrees after 20 times of freezing and thawing cycles, at the moment, the tower drum can better adapt to the low-temperature and high-humidity environment, the coating stripping possibility is low, and the anti-icing self-cleaning coating material can be applied to the wind driven generator tower drum. And the corrosion speed of the steel is reduced, so that the normal use time limit is longer.
