However, traditional floor heating be by heat-insulating shield (high molecule plastic foamed board) plastic heat radiation pipe, above-mentioned cement mortar and
What floor tile or timber floor formed, floor tile or timber floor, which are reached, from cement mortar from the heat that plastic tube gives out heats to room,
Heating and in diabatic process since existing cement mortar thermal coefficient is low, such as only 0.92w/m.k, from plastic heat radiation pipe biography
The coefficient of overall heat transmission to floor tile only has 65%, and part heat reaches heat insulation layer and runs outward to floor, causes energy waste.
In addition, cement mortar can generate temperature under long-time higher temperature conditions for the application in terms of geothermal engineering
Spend stress crack.Cement mortar generate the reason of thermal stress cracks be the heat of hydration after pouring completion, inside mortar not
It is easy to exhale and, cause mortar internal temperature higher, however mortar surface radiating rate ratio is very fast, in mortar surface and inside
The problem of there is certain temperature difference, cause occur compression inside mortar, and tensile stress then occurs in mortar surface, crack can be aggravated.
Summary of the invention
