Description

Preparation process of built-in carbon fiber electric heating layer reinforced floor and wooden floor thereof

Technical field

The invention relates to a preparation process of a reinforced floor and a wooden floor, in particular to a preparation process of a built-in carbon fiber electric heating layer reinforced floor, and belongs to the technical field of electric floor heating.

Background technique

In recent years, with the improvement of living standards and quality, geothermal heating has been widely introduced into people's home life. Geothermal heating is the heating method that uses the whole ground as a source of low-temperature radiant heating. It has the advantages that other heating methods can't match. It is consistently considered to be the most scientific and reasonable, the most economical and most economical. The characteristics of the hot and cold temperature gradient are in line with the traditional Chinese medicine health theory of the ancients, and it is an efficient heating system that regulates the microclimate of the room. Moreover, compared with the traditional heating method, the geothermal heating cancels the heating pipes and radiators in the room, which is more conducive to the layout of the living room, more scientific and energy-saving, and has higher service life and maintenance cost than the traditional heating method. Lower, easier to lay and affordable. Therefore, this heating method is recognized and accepted by more and more people.

With the development and application of geothermal heating technology, geothermal flooring began to gradually enter the family. At present, geothermal heating technology in China can be roughly divided into two categories: plumbing and electric heating. Water heating uses water as the heat transfer medium, and the hot water is circulated and heated in the pipeline. It is characterized by uniform heating temperature, but it is necessary to lay the water pipeline below the cement layer in advance; the electric heating is based on electric heating film and heating cable. The heating method is based on direct heating of electric energy for heating and heating, which is characterized by flexible and convenient heating, environmental protection and sanitation, and is particularly suitable for heating in the south. At present, the floor heating floor is a geothermal system that presets plumbing or electric heating, and then lays the floor above the water pipe or electric heating source. By heating the floor to achieve the purpose of heating the room. However, current plumbing and electric heating technologies also have some drawbacks. Plumbing, that is, low-temperature hot water floor radiant heating, its shortcomings are low thermal efficiency, slow heating rate, waste of energy, installation and after-sales service is very troublesome, water pipes will accumulate scale and lead to pipeline blockage, so the water circulation system should be cleaned regularly; The electric heating film, the heating cable and the electric heating block all adopt the principle of the traditional electric heating wire to generate heat, consume large electricity, and the heating body is easy to aging. These traditional geothermal construction costs are high, construction is difficult, and the floor laying on the heat source is extremely demanding. Due to the special nature of geothermal heating, the geothermal floor must have good thermal conductivity, good thermal stability, good environmental performance, and resistance. Good deformability. At present, various so-called geothermal floors have appeared on the market, but most of them are geothermal floors with solid wood composite structures, and the existing geothermal floors have problems of uneven heat dissipation, slow heating, and high heat loss.
