Benefits of technology

The technical effect of this patented technology is that it prevents heat from spreading through gaps on an alloy material's surface without affecting its properties or causing damage during use.

Problems solved by technology

This patented technical problem addressed in this patents relating to improving the efficiency and durability of nuclear fuel systems involves reducing heat losses during operation while maintaining their safety level. Insulating materials have been installed inside these components without affecting them' ability to conduct heat effectively. However, there may be some issues related to current methods such as weld seams, corrosion crackings, etc., especially when exposed to high temperatures over time.

Embodiment

[0032] Porous SiO 2 Granules are produced by the following steps:

[0033] Perform ion exchange on sodium silicate to obtain the first silicic acid with a pH of 2-3; pass the first silicic acid through an anion exchange resin to obtain a second silicic acid with a pH of 5-6; pass the second silicic acid through cation exchange Resin, to obtain the third silicic acid with a pH of 3-4; add the third silicic acid to the reaction kettle, add KOH solution at the same time, heat at 120°C for 40h, and obtain SiO with a solid content of 45%. 2 solution, the SiO 2 The solution is dried and ground to obtain the porous SiO 2 particles.

[0034] Titanium dioxide is produced through the following steps:

[0035] TiO 2 ·nH 2 The molar ratio of O and KOH is 0.5, add an appropriate amount of water and grind it evenly in a mortar, then sinter in a muffle furnace to 880°C, keep it for 2 hours, and slowly cool to room temperature to obtain the intermediate product K 6 Ti 2 o 7 ;

Abstract

The invention discloses an efficient metal reflection type heat preservation material. The material comprises a plurality of layers of stainless steel foils arranged in parallel; each stainless steel foil is provided with a concave-convex structure; the concave-convex structures of every two adjacent stainless steel foils are arranged in a staggered mode; at least one face of each stainless steel foil is provided with a high-reflection porous coating; each high-reflection porous coating is provided with an open pore structure extending from the interior of the coating to the surface of the coating, and the heat reflectivity of the high-reflection porous coating is larger than or equal to 0.9. According to the heat diffusion principle, the porous structure of the high-reflection coating on the surface of each stainless steel foil is designed, so that heat can be effectively prevented from spreading from gaps between the stainless steel foils. The high-reflection porous coatings can effectively reflect heat radiation, the heat reflectivity of the high-reflection porous coatings is larger than or equal to 0.9, and the heat insulation effect can be achieved.
