Description

A kind of production method of electric heating floor Electric radiant Heating Film

Technical field

The present invention relates to the production method of Electric radiant Heating Film, particularly a kind of production method of electric heating floor Electric radiant Heating Film.

Background technology

Electric radiant Heating Film ground plate technique is be different from radiator, air-conditioning, the radiator point heating system that is representative and take heating cable as the line formula heating system of representative, the low-carbon (LC) heating high-tech product adopted in face formula heating field.Electric radiant Heating Film is the translucent polyester film that can generate heat after a kind of energising, and take Electric radiant Heating Film as heater during work, heat is sent into space in the form of radiation, first human body and object are obtained warm, its resultant effect is better than traditional convection current heating system.This exclusive heating mode, indoor temperature is even, pure and fresh, comfortable quiet to allow people feel, and the drying and sultry not having tradition heating to produce, and also can not cause indoor floating ash because of air-flow.Electric heating ground film not only heated room air, and the human health-preserving that simultaneously temperature-rise period from bottom to top meets the warm head of warm foot learns principle.In addition, intelligent temperature control function can allow people follow one's inclinations heating, promotes behavior energy saving, opens the life of all new generation hommization low-carbon (LC).Because Electric radiant Heating Film is pure resistor element circuit, therefore its conversion efficiency is high, and except sub-fraction loss (2%), the overwhelming majority (98%) is converted to heat energy.

Electric radiant Heating Film is the translucent polyester film that can generate heat after a kind of energising, a kind of special heating products be made up between two-layer insulation mylar through printing, hot pressing of conductive special ink, metal current-carrying bar.Ceiling panei heating with electro-thermal film is a kind of electro-thermal heating mode, it take electric power as the energy, take Electric radiant Heating Film as heater, most of heat is sent into room with forms of radiation, wall, furniture are heated up, and then by heat convection heating indoor air, and make it have the features such as constant temperature is adjustable, economy is comfortable by independently attemperating unit.Can be arranged in ceiling, below in dado or floor.In order to larger performance Electric radiant Heating Film utilization ratio, require in Electric radiant Heating Film and between floor and body of wall, use heat-barrier material heat-insulation and heat-preservation, preventing heat outwards to scatter and disappear.The Electric radiant Heating Film in each room is linked to be an element loop, is controlled by a thermostat, and thermostat can set operating time and heating rooms temperature, makes Electric radiant Heating Film within the time of setting automatically according to the work of room temperature situation or disconnection.When room temperature reaches the temperature of thermostat setting, Electric radiant Heating Film quits work, and reaches energy-conservation object.Electric heating thin-film mainly contains two kinds of modes, i.e. radiation and conduction principle.

The base material of general electrothermal film is the special polyester film of PET, and heater is special electrically conductive ink, be accompanied by the metal bus bars of silver slurry and conduction is conductive lead wire, is composited finally by under hot pressing.This Electric radiant Heating Film complex manufacturing technology, cost is higher, brings difficulty to applying.

Summary of the invention

Based on the shortcoming that background technology exists, the object of this invention is to provide a kind of cost greatly to reduce, and there is the production method of the coefficient of safety more electric heating floor Electric radiant Heating Film of advantages of higher, and by a large amount of production practices, find optimized technological production norm, obtain very outstanding novel floor film, there are very wide market prospects.

Concrete technical scheme of the present invention is as follows:

A kind of production method of electric heating floor Electric radiant Heating Film:

(1) spray: with powder spraying apparatus positive and negative two surfaces of powdered graphite spray painting to fire retardant papers, under electrostatic interaction, powder can be adsorbed in surface of the work uniformly, and after baking-curing of heating, bisque levelling becomes uniform rete;

(2) pulverize: band coating paper is carried out microlith shape (paper scrap) segmentation by paper using pulverizer;

(3) share equally: useless broken paper scrap is uniformly distributed on electric heating floor general purpose polyester film, utilize dull and stereotyped microseism equipment to control paper scrap all standing polyester film;

(4) conflux: put into fine copper bar at polyester film two ends according to the manufacturing dimension of product, as the two poles of the earth of power supply input;

(5) compound: above another formed objects polyester film is covered, by high-temperature laminating, product is sealed, waterproof insulation.

Described step (1) spraying coating process is preferably: with static plastic spraying machine positive and negative two surfaces of powdered graphite spray painting to fire retardant papers, fire retardant papers selects thickness to be 0.5-0.8mm, 110-130g/ square, under electrostatic interaction, powder can be adsorbed in surface of the work uniformly, bisque levelling after baking-curing of heating becomes uniform rete, and thicknesses of layers controls at 0.1-0.15mm; The amount of dusting controls in 70g/min-80g/min, and after spraying, band rete paper resistivity reaches 6-10 Ω/cm;

During test, fixed width is 1 centimetre, and length selects 1,2,3,4,5,6,7,8,9,10 centimetres of paper blocks, calculates every square centimeter of resistance value after measuring, and gets 10 pieces of mean values whether qualified as inspection;

Described step (2) disintegrating process is preferably: band coating paper is carried out paper scrap segmentation by paper using pulverizer, and each microlith size controls at 0.9-1.2mm 2;

Described step (3) shares optimal process equally: be uniformly distributed on electric heating floor general purpose polyester film by useless broken paper scrap, dull and stereotyped microseism equipment is utilized to control paper scrap all standing polyester film, void area is less than 1%, and paper scrap thickness peak is no more than 1.5mm;

Described step (4) optimal process that confluxes is: put into wide 0.8-1cm at polyester film two ends according to the manufacturing dimension of product, the fine copper bar of thick 0.5mm, as the two poles of the earth of power supply input.

Usefulness of the present invention is:

1, production method of the present invention uses graphite powder and fire retardant papers substituting import one electrically conductive ink and silver to starch, and cost declines greatly, only has about 40% of original cost;

2, do not re-use dedicated printer (often blocking shower nozzle), production efficiency improves greatly, and average daily output improves about 300%;

3, be ink strip heating compared to prior art Electric radiant Heating Film, heating uniformity coefficient depends on the unit are quantity of ink strip, the uniform whole plane of the present invention's improved craft stone ink powder paper scrap, heating evenly;

4, before the present invention transforms rear heating temp curve and prior art transformation, heating temp curve is basically identical, and the present invention transforms rear stable temperature than low before transformation, and change is comparatively slow, and coefficient of safety is higher;

5, the electric heating floor film market demand is increasing, and new electrically heating floor film provided by the invention has extraordinary market prospects.
