Mats of mineral wool

SYSTEM DESCRIPTION

Mats of ROCKWOOL mineral wool lined with one-sided metal mesh wire sewn to the layer of mineral wool, manufactured in five standard versions: WIRED MAT 70, WIRED MAT 80, WIRED MAT 105, ALU-WIRED MAT 80 *, ALU-WIRED MAT 105 *.
* With a layer of aluminum film located between the grid and mineral wool.

APPLICATION

Mats on the grid WIRED MAT for isolating high-flat surfaces, pipes, pipelines, valves and other devices and surfaces that require a high mechanical resistance of insulating material while simultaneously its flexibility and ease of installation, in particular: the walls of boilers, electrostatic precipitators, flue channels, steel chimneys, pipelines of high and low pressure steam and water, housing igazovyh steam turbines, compressors, liner, pressure reducing stations, valves, fans.
Surface with special requirements, eg. relating to corrosion, can be protected with mats on a grid of stainless steel (this also applies to crosslinking of wire).

Thermal conductivity

Thermal conductivity for different matrices on the grid can be expressed in formulas:

+ 9,904З10 -5 t m + 3,511З10 -7 t m 2 WIRED MAT 80 λ = 3,070 Z10 9.904 Z10 -2 + -5 t m + 3,511 Z10 -7 t m 2

+ 9,010З10 -5 t m + 2,586З10 -7 t m 2 WIRED MAT 105 λ = 3,231 Z10 9.010 Z10 -2 + -5 t m + 2,586 Z10 -7 t m 2

where
– средняя температура слоя изоляции, t m =(t a + t o )/2 t m - the average temperature of the insulation layer, t m = (t a + t o) / 2
– температура изолируемой поверхности (элемента) t a - temperature of the insulated surface (element)
– окружающая температура t o - ambient temperature
