Aerogel As Thermal Insulation Material

图片
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...

What’s the Difference? Drywall vs. Plaster

图片
If you’re thinking of taking on a wall construction project in your home, you’ll likely hear of two options: drywall and plaster. Newer homes tend to feature drywall, a material comprised of gypsum sandwiched between two sheets of paper and usually sold in 4-foot-by-8-foot panels. Drywall installs quickly and fairly easily by screwing it into the studs of the wall, and today it comes in a variety of thicknesses and other options to choose from. Plaster and lath, on the other hand, is a more labor-intensive but high-end wall treatment where workers nail lengths of wood called lath to the studs and then apply several coats of plaster over top, used in most homes built before World War II. Both methods have their respective strengths and weaknesses, so we’re breaking down the two  oil pipeline insulation   materials here—drywall vs plaster. Keep reading for what you should consider before planning your next project. Plaster is more labor-intensive than drywall. In fact, the ...

Aerogel Adiabatic Insulation Board Allows Pollution To "zero" Emissions

图片
In the ninth China (Beijing) International Building Energy Conservation and New Construction Material Exhibition, Zhengzhou J oda Technology Co., Ltd. showed  the thinnest building insulation board - A erogel  insulation board  ,which attract a large number of visitors. According to the introduction , this kind of  Aerogel  insulation board main material is   A erogel  . A erogel  was first used in the field of aerospace and military, and  now quietly heading  into the civilian market, it has been gradually applied to the construction, industrial insulation, cold storage, ship s  and other fields. It ’ s both in insulation and water-proof,even thinning. A erogel  insulation board  is very light and thin,for example,To 240 mm solid clay brick wall requirements 75% building energy efficiency standards ,when use of ordinary insulation material needs 90 mm thickness, however when we use A erogel insulation board is only...

Analysis And Prevention Of Building Exterior Wall Insulation Water

Analysis and Prevention of Building Exterior Wall Insulation Water As the building insulation wall insulation layer is not allowed to enter the water, if the insulation layer of water, it is not insulation, and more serious may cause leakage. Outside the wall insulation layer of the main parts: The outer wall has cracks or holes; the window at the mouth; highlight the external walls of the eaves, decorative lines or other components and the wall intersect the root: wall exposed glass mesh. 1, resulting in  building insulation materials  water causes: (1) not in accordance with the rules of design or construction, resulting in cracks in the external walls, holes and other water parts. (2) highlight the wall decoration line, eaves and other surface down slope, water; doors and windows under the mouth of the slope or slope is small, the surface flatness is poor, there is water; bottom slope to the inside side, no dripping water eaves or eagle Mouth, water along the botto...

The aerogel can achieve "shape memory"

图片
The chemists have developed the aerogel that can memorize the shapes. Chemists from the University of Missouri recently have produced out rubber-like aerogel with elasticity. It is reported that the aerogel can achieve "shape memory". The industry expert pointed out that the aerogel is to use the gas in silicon dioxide, metal oxide, or polymer gel instead of liquid solvents, which can be used in various products, including submarine oil pipeline insulation materials, various types of insulation materials usage in the space missions. In addition, this particular type of polyurethane aerogel has a strong elasticity, can be bent in any direction or be crushed, and then still restored to the original shape. It is reported that the aerogel can always maintain the deformed shape after the deformation and cooling process, and when the temperature rises to room temperature, they will return to the original undeformed shape. source: http://www.aerogelinsula...
