Product composition and characteristics
|
This product is made of specially synthesized inorganic silicate solution Aluminum silicate Fiber, heat reflective material and selected hollow Glass It is made of micro beads. coating It is an inorganic single component, non-toxic and harmless. The thermal conductivity of the coating is very low, only 0.033W/m.k. The thermal insulation effect is obvious, and the inhibition efficiency can reach about 90% under certain thickness conditions. It can also effectively keep cold for low-temperature objects, and effectively restrain the temperature rise of low-temperature objects caused by external heat sources due to heat conduction.

Working mechanism
|
The overall structure of the coating is equivalent to creating the heat preservation and insulation mechanism of the thermos ceramics When heated at high temperature, the air inside the microsphere cavity will not produce thermal convection. Hollow ceramic beads are closely arranged and there is a three-dimensional air layer between them, which also avoids the generation of thermal convection. Inorganic with relatively low thermal conductivity Film-forming substance As the support of the coating, the thermal insulation shielding layer with static air layer and inorganic film-forming material is jointly constructed. The heat reflective material is added as an auxiliary filler, so that the thermal conductivity of the coating is close to the vacuum thermal conductivity, which plays an effective role in thermal insulation.

|
|
Ensure that the painted surface is free of dust, oil stain, rust, brittle layer and other foreign matters, and ensure that the painted surface is clean and dry without pollution. Polish and roughen the coated surface as much as possible to ensure the surface roughness within the range of 25-40 μ m. If the metal surface is manually polished to St3 or sandblasted to Sa2.5, the coating effect will be better.
