Mesoporous Insulation Products
Always adhering to independent R&D and production, and having core independent intellectual property rights
Mesoporous materials are a class of porous materials with such features as pore size of 2-50nm, very high specific surface area, regular pore channel structure, narrow pore size distribution and continuously adjustable pore size according to the naming rules of the International Union of Pure and Applied Chemistry (IUPAC).
Mesoporous composite insulation products are nanoscale porous insulation products composed of continuous-phase inorganic fibers (such as glass fibers, ceramic fibers and basalt fibers) or fiber fabrics as reinforcing materials and mesoporous materials.
As a kind of high-end new insulation materials, mesoporous insulation materials are non-combustible and have low thermal conductivity, only half or less of that of traditional materials under the same working condition; they can save more energy, space and auxiliary materials, and have been widely used in many fields such as nuclear industry, building, national defense, military industry and aerospace at home and abroad.
Mesoporous materials have the following advantages for thermal insulation:
Mesoporous Insulation Materials
TS series mesoporous insulation blankets independently developed and produced by UniNano Advanced Materials have excellent performance and high cost effectiveness, and have been widely used for buried pipes, overhead pipes and various industrial equipment.
The mesoporous insulation blankets are nanocomposite insulation materials prepared from mesoporous silica materials and inorganic fibers. Mesoporous materials have such features as high specific surface area, large porosity and small pore size. The composite mesoporous insulation materials have excellent characteristics such as low thermal conductivity, high-temperature stability, overall hydrophobicity, flame retardancy (Class A1), sound insulation and noise reduction, and are safe, energy-saving and environmentally friendly.
Mesoporous Insulation Principle
The pore size of mesoporous insulation materials is smaller than the free path (70nm) of gas molecule collisions, and gas molecules involved in heat transfer cannot pass through, thus essentially cutting off heat conduction of gas molecules; due to the existence of nearly infinite mesopores, the heat flow can only be transferred along the pore walls when it is transferred in the solid, and nearly infinite pore walls constitute a nearly “infinite long path” effect, greatly reducing the heat conduction ability of the solid.
Due to small pore diameter of mesoporous materials, air molecules lose the ability to flow freely and cannot be involved in heat convection.
The addition of nano additives which are opaque to infrared rays effectively blocks heat radiation.
Performance Advantages of Materials
Unique mesoporous insulation mechanism, extremely low thermal conductivity and energy saving rate of greater than 30%, significantly reducing heat loss.
The solution of composite with traditional materials is adopted, and the thickness is reduced by about 1/3 compared with the solution of traditional materials, saving a lot of space for erection of large equipment and pipelines.
Pipe structure members and cladding layer materials are greatly reduced, and earthwork excavation for buried pipes can be reduced by more than 1/3, saving labor and materials.
High tensile strength, no looseness at high temperature (above 220°C), and long service life.
