Description

A far-infrared carbon fiber integrated wall heating board and its production process

technical field

The patent of the present invention relates to the technical field of a heating technology and its manufacturing process, especially a far-infrared carbon fiber integrated wall heating plate and its production process. The utility model has the energy-saving effect, satisfies people's daily heating requirements, and also has many advantages such as elegant appearance, durability, and health benefits. It is easy to manufacture and process, and is suitable for promotion.

Background technique

With the development of industrialization and the rapid increase of urban population, the heat energy consumption of industry, life, and heating has increased sharply. A large amount of dust, sulfur dioxide and other pollutants emitted by coal-fired heating boilers are increasingly threatening people's health. One of the important causes of smog in recent years;

In order to protect the ecological environment and people's health, fundamentally eliminate air pollution, and reduce the impact of smog on people's health, the country has successively issued a number of policies, such as traffic restrictions, lower heating temperatures, and energy-saving and emission-reduction measures in factories. There are also a variety of environmentally friendly heating in the existing technology, which makes the heating technology more diversified, such as district heating systems, solar hot water air-conditioning systems, geothermal heating systems, electric heating systems, etc. Among them, the electric heating system is used for its convenience. With the advantages of good reliability, high controllability, strong safety, high utilization efficiency, and zero pollution emissions, with the support of relevant preferential policies in the power system, it has gradually transformed from an auxiliary heating method to one of the main heating methods; as of 2015 In 2019, China's existing residential building area was nearly 53 billion square meters, of which the heating system met the standard and did not need to be renovated, accounting for only about 3.5%. The energy-saving renovation of the heating system of existing residential buildings involves the interests of all parties. , it is difficult to implement. Only by comprehensively evaluating the effect of energy-saving renovation from the results of the renovation can the smooth progress of energy-saving renovation work be better promoted. Through the analysis and research of China's existing building heating system, combined with China's existing building heating system Problems in the system: poor energy saving effect, high energy consumption, poor comfort, poor safety performance, difficulty in metering and charging, high operating costs, etc. Due to problems in the heating management system and heating technology, various heating methods have varying degrees of inadequacy Defects: If the heating season cannot be advanced or extended according to housing needs, and the heating fee is fixed, the user has to pay the heating fee regardless of whether he lives or not, causing social injustice and unreasonable charging;

People are eagerly looking forward to the invention and creation of new heating technology to meet the requirements of low energy consumption, low emission, low radiation, and low risk. There is a kind of electric wall heating technology in the existing design, which uses the principle of electric resistance to generate heat for decoration and modeling. At the same time, it meets people's heating requirements, but this technology uses the traditional convection heating principle, which has high energy consumption and large radiation, and it will also make the room dry and uncomfortable, which does not meet people's increasingly high material culture. Scientists have conducted some research on carbon fiber materials and found that carbon fiber has the characteristics of low energy consumption and low radiation, and its strength is high, which can replace some metal materials, such as manufacturing bicycles, badminton rackets, car shells, bats, etc. , but Dimension has never been able to solve its fatal shortcoming when making heating cables, that is, its joints are easily broken, resulting in open circuits or virtual connections, because carbon fiber has a polar molecular structure, while copper material has a non-polar molecular structure. Conduction will inevitably produce unstable factors such as turbulence, which will cause frequent damage to the joints. This is also the main reason why the existing technology does not use carbon fibers, but uses copper-nickel alloys as the heating core; because when carbon fibers are used as heating materials, the joints at the joints It is unstable and cannot be promoted and applied in a large area;

Contents of the invention

The purpose of the present invention is to provide a far-infrared carbon fiber integrated wall heating panel and its production process, which solves the shortcomings of high energy consumption, high pollution, and high radiation in traditional heating technology.

In order to solve the above technical problems, the present invention provides a far-infrared carbon fiber integrated wall heating panel and its production process, wherein:

A far-infrared carbon fiber integrated wall heating panel, in order from top to bottom, including: a protective layer, a PU layer, a carbon fiber heating layer and a decorative layer; the carbon fiber heating layer is provided with a carbon fiber connector;

As an example, the carbon fiber connector is configured as a twisted-pair multi-strand structure, that is, a plurality of connecting wire-type compression structures made of a structure similar to a crystal head, and the external copper-nickel Connect the cable for a plug-in connection similar to the network port;

As an example of practical application, when the carbon fiber branch line in the crystal head comes out of two joints and is connected, then after the connection is pressed, it is verified by experiments that its service life is not lower than that of ordinary carbon fiber and copper-nickel wire connection. 1.5 times of the time of use, because the two carbon fibers are connected to the copper-nickel wire, and according to the design principle, it should have a service life of 2 times. Considering the use environment and the real data of the experiment, it should not be less than 1.5 times of the life of a single strand It is the safest experimental data; by analogy, if the carbon fiber pressed into the crystal head is connected to 10 strands of joints, then the service life that this design can achieve will not be lower than 15 times the value of the existing technology. The principle greatly enhances the service life of carbon fiber;

As an example, the number of strands of the carbon fiber connector is not less than 2;

As an example, the carbon fiber connector can also be connected in series with a microcomputer temperature controller to facilitate the automatic setting and adjustment of the indoor temperature;

The material has the lowest thermal conductivity, and is also the most cost-effective among thermal insulation materials; moreover, the polyurethane material has a stable porosity structure and is basically a closed-cell structure, which not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average service life of polyurethane foam insulation structure can reach more than 30 years under normal use and maintenance conditions.
