Thermal insulation zs-1/1000 ℃ high temperature thermal insulation coating for steam turbine high temperature pipeline in power plant

The steam turbine is an externally fired rotary machine that can convert steam heat energy into mechanical work. After entering the steam turbine, the steam from the boiler will pass through a series of annular nozzles and moving blades in turn to convert the heat energy of steam into the mechanical energy of turbine rotor rotation. In the steam turbine, energy conversion is carried out in different ways to form a steam turbine with different working principles.

In order to improve the thermal efficiency of the steam turbine, in addition to constantly changing the efficiency of the steam turbine itself, including improving the blade profile design of all stages of blades, it can also reduce the valve And steam inlet and exhaust The Conduit , loss of external surface of turbine shaft seal sleeve, etc. Traditional thermal insulation rock wool is used for heat insulation, with thick thermal insulation layer and poor aesthetics. Moreover, rock wool material is harmful to human body, and long-term work in this environment may cause cancer.

The market expects to pass nanometer ceramics Thermal insulation coating Its application achieves the thermal insulation effect of the original rock wool insulation, while reducing the thickness of the insulation layer to achieve the effects of safety, environmental protection, energy conservation, beauty, etc. In combination with years of experience in high-temperature coating research and development, Song Gong, a coating related person from Zhisheng Weihua, has developed and promoted special thermal insulation materials for various parts of steam turbines, ZS-1 High temperature nano ceramic thermal insulation coating and ZS-211 Space reflective thermal insulation coating.

ZS-1 High temperature nano ceramic heat insulation coating is made of specially synthesized inorganic silicate solution, aluminum silicate fiber, heat reflective material and selected hollow glass beads. The paint is an inorganic single component, harmless and harmless. The thermal conductivity of the coating is low, only 0.03W/m.k The heat insulation effect is obvious, and the relieving efficiency can reach 90% about. It can also effectively keep cold for low temperature objects and effectively ease the temperature rise of low temperature objects caused by external heat sources due to heat conduction.

form:

It is made of specially synthesized inorganic silicate solution, aluminum silicate fiber, heat reflective material and selected hollow ceramic beads. Water friendly, harmless.

mechanism:

The overall structure of the coating is equivalent to creating the thermal insulation mechanism of the thermos. The air inside the cavity of the hollow ceramic beads added to the coating will not produce thermal convection when heated at high temperature. The hollow ceramic beads are closely arranged and there is a three-dimensional air layer between them, which also avoids the generation of thermal convection. The inorganic film-forming material with relatively low thermal conductivity is used as the support of the coating to jointly construct the thermal insulation shield layer with static air layer and inorganic film-forming material. 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.
