Silica Thermal Insulation Aerogels Felt For Oil Ducts

Silica Thermal Insulation Aerogels Felt For Oil Ducts

Description

According to the different drying processes, it is mainly divided into supercritical drying process and atmospheric pressure drying process. Other mass production technologies have not been realized, such as vacuum freeze drying and subcritical drying.
Supercritical drying technology is the earliest to realize batch preparation Aerogel technology, which is relatively mature, and it is also the technology adopted by Aerogels enterprises at home and abroad. Supercritical drying is designed to achieve a critical point in the drying process by pressure and temperature control to form a supercritical fluid. The solvent in the supercritical state has no obvious surface tension, so that the gel can be dried. Maintain a good skeleton structure during the process. At present, the batch production technology has generally adopted carbon dioxide as a drying medium, referred to as carbon dioxide supercritical drying technology.
Atmospheric pressure drying A new type of Silica Aerogel preparation process is currently the most active and most promising Aerogel batch production technology. The principle is to modify the gel skeleton by using hydrophobic groups, to avoid the silicon hydroxy groups on the surface of the gel pores and to improve the elasticity, and to replace the original high specific surface area of water or ethanol with a low surface tension liquid. Direct drying is carried out to obtain Aerogel Felt material with excellent properties.

Advantages

Physically Robust and Impact Resistant
Soft and flexible but with excellent spring back, Aerogel recovers its thermal performance even after compression events as high as 100 psi, protecting critical assets from compromise due to tool strikes, footfalls, lifting, and transportation
Lower thermal conductivity coefficient
Thermal conductivity coefficient less than 0.016w/(m,k)at room temperature,
several times or even dozens of times lower than traditional heat preservation materials, and with better heat preservation effect.
Thinnest and lightest thermal insulating material
Under the same heat preservation effect, the dosage of our company`s SiO2 aerogel composite material is only 1/5 to 1/3 of traditional materials` . So it can be applied to dense pipeline and narrow space and achieve a good effect of heat or cold preservation. And greatly convenient for installation and save the cost of the protective layer.

Application

Metallurgy: torpedo tank, steel ladle, tundish, coke oven door
Machinery: industrial stove, electric stove, stove door, stove cover
