The current popular heating method is hot water or steam heating. This method requires the laying of a large number of pipes, and at the same time requires many auxiliary structures such as heat exchange stations and compensators. Trial operation requires a lot of manpower and material resources
At the same time, this kind of heating effect is unstable, and the heating effect of high-rise residents in buildings is often unsatisfactory. Moreover, the preparation of hot water and steam requires the burning of a large amount of fossil fuels, which causes great pollution to the environment.

Abstract
The invention discloses a carbon fiber cement base and a manufacturing method thereof and a winter indoor heating device. The carbon fiber cement base is prepared from the following components in parts by mass: 1200-1305 parts of cement, 600-652.5 parts of water, 16.83-20.85 parts of carbon fiber, 197.5-227.5 parts of silicon powder, 8-11 parts of dispersing agent and 4-6 parts of defoaming agent.The winter indoor heating device comprises a heat generating layer which is the carbon fiber cement base. A maintenance layer is connected on the lower side surface of the heat generating layer and apackaging layer is connected on the lower side surface of the maintenance layer and the upper side surface of the heat generating layer. Electrodes are connected to the left side surface and the right side surface of the heat generating layer and connected with leads. The resistivity of the carbon fiber cement base material is ensured; the heat generating layer is separated by the packaging layerand has good heat resistance, alkali resistance, insulativity and the like and is high in safety; a radiant heating method is adopted, the heating effect is good, the comfort level is high, a warm environment can be obtained without heating too much and energy is saved; and operation is easy and the number of needed accessory devices is low.
Description
technical field [0001] The invention relates to the application technology of the electrothermal performance of the carbon fiber cement base, in particular to a carbon fiber cement base, a production method and a winter indoor heating device. Background technique [0002] With the improvement of people's living standards, the indoor environment has become an important consideration in housing design. And heating in winter is essential. The current popular heating method is hot water or steam heating. This method requires the laying of a large number of pipes, and at the same time requires many auxiliary structures such as heat exchange stations and compensators. Trial operation and so on need a lot of manpower and material resources. At the same time, this kind of heating effect is unstable, and the heating effect of high-rise residents in buildings is often unsatisfactory. Moreover, the preparation of hot water and steam requires the burning of a large amount of fossil fu...
