Nanomaterials possess certain unique characteristics: when the size of a material shrinks to a certain scale, it becomes necessary to replace the classical mechanical perspective with quantum mechanics to describe its behavior. For instance, when the particle size of a powder decreases from 10 micrometers to 10 nanometers, although the linear dimension changes by a factor of 1,000, the corresponding change in volume is an astonishing 10^9-fold. Consequently, the behaviors of these two scales will exhibit significant differences.
Nanostructured materials, often referred to as nanomaterials, are materials whose structural units have dimensions ranging from 1 nanometer to 100 nanometers.
1. Nanomaterials possess certain unique characteristics. When the size of a material shrinks to a certain scale, it becomes necessary to replace the classical mechanical viewpoint with quantum mechanics to describe its behavior. For instance, when the particle size of a powder decreases from 10 micrometers to 10 nanometers, although the linear dimension changes by a factor of 1,000, the corresponding change in volume is an astonishing 10^9-fold. Consequently, the behaviors of these two scales will exhibit significant differences.
2. Due to the dramatic increase in the number of particles, nanomaterials exhibit an enormously enlarged total surface area, which in turn leads to a significantly higher proportion of atoms at the particle interfaces—often reaching around half of the total atomic count. As a result, nanomaterials frequently display remarkable properties in areas such as optics, electricity, magnetism, heat, mechanics, and chemistry, setting them apart from their macroscopic counterparts. For example, the melting point of gold is 1063°C; however, when gold is reduced to nanoscale powder, its melting point can drop to as low as 330°C. Similarly, the melting point of silver is 961°C, but when it’s made into nanoscale silver powder, its melting point can be lowered to just 100°C. Another example is that certain catalysts, when fabricated into nanomaterials, experience a substantial increase in surface area, leading to a dramatic enhancement in catalytic activity and allowing the temperature of catalytic reactions to be reduced by several hundred degrees Celsius.
Nano-insulation coatings do not consist entirely of nanoscale components; rather, they contain only 70% nanomaterials. This product is formulated using nano-aerogels and nano-ceramic reflective particles—both imported from the U.S.—with specific surface areas exceeding 800 square meters per gram, as well as various other nanomaterials such as nano-titanium and nano-rare earth elements. These materials serve as the primary base, combined with inorganic catalysts to create a variety of distinct inorganic thermal insulation materials. The formulation process involves multiple stages and represents a world-first technological breakthrough, applying micro- and nanotechnology originally developed for the aerospace industry to thermal insulation applications. This innovation effectively addresses the challenges associated with insulating and constructing complex-shaped equipment, such as spherical tanks, floating-roof tanks, and irregularly shaped devices.
The product boasts strong adhesion, does not crack or peel, offers excellent thermal insulation, and also features anti-corrosion, waterproof, fire-retardant, UV-resistant, soundproof, insulating properties. It is lightweight, easy to install, and has a long service life.
