Aerogel Insulation Blanket

The microstructure of silica aerogel is effective in limiting the propagation of local heat excitation, and its solid-state thermal conductivity is 2-3 orders of magnitude lower than that of the corresponding glass state materials. Nano-pores inhibit the contribution of gas molecules to heat conduction. The refractive index of silica aerogel is close to L, and the ratio of annihilation coefficient of IR and visible light is more than 100, which can effectively penetrate sunlight and prevent ambient temperature from infrared thermal radiation, and become an ideal transparent insulating material, which has been applied in solar energy utilization and building energy conservation. By means of doping, the radiant heat conduction of silica aerogel can be reduced, and the thermal conductivity of carbon  aerogel  under normal temperature and pressure can be up to 0. 013w/m K, is the lowest thermal conductivity of solid materials, is expected to replace polyurethane foam as a new typ...

They are calcium silicate, mineral fiber, cellular glass, expanded silica, elastomeric foam, foamed plastic, refractory fiber, and insulating cement. These  heat insulation material  and their accessories make up the primary insulation devices and systems, having the different mechanical and chemical properties for insulation. They can be in the form of rigid boards, blocks, pre-formed shapes, flexible sheets, flexible blankets, cements, and foams for application. As insulation products, their functions include facilitating temperature control of process, conserving energy by reducing heat loss or gain, increasing operating efficiency of HVAC systems, and reducing emissions of pollutants to the atmosphere. But these functions are not performed to their full extent with the absence of one important factor, which is often overlooked in building insulation: the accessories. When insulation accessories are not given much attention, the dependability and performance of the entir...

There are a diverse range of materials used for insulation. In this article, we will list out the comparison between five most common types’  wall insulation materials , fiberglass, mineral wool, cellulose, polyurethane foam and polystyrene foam with aerogel insulation. 1. Fiberglass Fiberglass is the most common insulation. Because of how it is made, by effectively weaving fine strands of glass into an insulation material, fiberglass is able to minimize heat transfer and is an excellent non-flammable insulation material. Low cost is another benefit of fiberglass as it is readily available. The main negative factor of fiberglass is the danger of handling it. Since fiberglass is made out of finely woven silicon, glass powder and tiny shards of glass are formed. These can cause damage to the eyes, lungs, and even skin if the proper safety equipment isn’t worn when handling fiberglass. Aerogel insulation, four times more efficient than fiberglass, has seen reductions in cost ...

New technology widely used applications Industrial market scale is growing, to Karamay heavy oil mining, for example, for heavy oil extraction and transformation equipment investment 800 million yuan, of which nearly 200 million yuan budget for the pipeline  heat insulation material  transformation. Feng Zhao believes that the field of industrial insulation is a new market, is the incremental space, which is not make a difference of the original profit chain , and the industrial market can prove its advanced nature of the material. In the field of energy need to deal with state-owned enterprises , including Feng Zhao , people believe that the current cost of this new material only one-sixth of similar foreign products, cost-effective, can help enterprises to solve the problem, cooperation is very good prospects. But for the future, but also they hope to cooperate with state-owned enterprises to jointly promote this technology. This new material used in the civilian market,...
