The heating element is an alloy foil sheet with a heating circuit etched, the mica substrates are mica laminated paper, and the electro-thermal film is formed by pressing the alloy foil sheet and the mica substrates through high-temperature adhesives and a high temperature pressing process. The mica electro-thermal film is simple in structure and high in thermal conversion efficiency; and heating equipment produced through the mica electro-thermal film meets utilization requirements of being safe and comfortable and environment friendly and energy saving.
Description
Technical field
The present invention relates to the mica material manufacture field, be specifically related to a kind of mica Electric radiant Heating Film.
Background technology
Mica paper is a kind of insulating material of high-quality, have the advantages such as nontoxic, tasteless, high temperature resistant, high pressure resistant, ageing-resistant, corrosion-resistant, that electric property is stable, particularly its high temperature resistant and re-workability is that other material institute is irreplaceable, so the every aspect of mica paper in more and more being applied to live.
Traditional heating source comprises combustion fuel and uses the electric heating element heat production.Though the former heat energy conversion ratio is high, environmental pollution is more serious, and the latter is the various heating equipments that utilize electric heating element to make, and utilizes cross-ventilation to certain space transferring heat, and is easy for installation, is easy to family and uses.But the electric heating element of this heating equipment usually is exposed to outer or is simple quarantine measures, there is certain potential safety hazard, simultaneously because electric energy is a kind of high energy price, if the thermal conversion efficiency of its equipment is not high, do not meet the life requirement of low-carbon environment-friendly yet, therefore should not use for a long time yet.
Summary of the invention
The objective of the invention is the deficiency that exists in order to solve prior art, a kind of mica Electric radiant Heating Film is provided, it is simple in structure, and thermal conversion efficiency is high, use heating equipment that this mica Electric radiant Heating Film makes can the to satisfy effectively safety and comfort, the instructions for use of environmental protection and energy saving.
The objective of the invention is to be achieved by the following technical measures: a kind of mica Electric radiant Heating Film, be the composite multi-layer structure, the centre is heat generating member, being close to the heat generating member two sides is mica substrate, described heat generating member is the alloy foil sheet that etching has heating circuit, described mica substrate is that mica is crossed gummed paper, and described Electric radiant Heating Film is formed by high temperature adhesive and the compacting of high-temperature laminating technique by alloy foil sheet, mica substrate.
In technique scheme, described alloy foil sheet is made by the SUS430 stainless steel, and thickness is 0.02mm ~ 0.03mm.
In technique scheme, described Electric radiant Heating Film is five-layer structure, is followed successively by mica substrate, alloy foil sheet, mica substrate, aluminium foil, mica substrate, and described mica substrate is that mica is crossed gummed paper.
In technique scheme, it is 0.3mm that described mica is crossed gummed paper thickness.
Mica Electric radiant Heating Film of the present invention has following advantage, can be used for making heating equipment:
1. electric property is excellent, because electric current is the high-quality electrical conductivity alloy by even thickness, and alloy has heat-resisting quantity, so can bear stronger conveyance capacity, can bear the shock-testing of 1.65 times of rated voltages and (switch on 3 seconds, cut off the power supply 3 seconds, continuous 500 times), can not damage.Single face is crossed gummed paper with the 0.3mm mica, and is compressing by high temperature, withstand voltage reaching more than the 5KV, and high temperature can reach 400 ° of C and also can delamination not bubble.This point is particularly important to the heating equipment of high-power large electric current.
2. be equal in the situation, this alloy-foil type Electric radiant Heating Film power density can be accomplished 0.95W/cm
2, because the heating equipment surface temperature will meet the safety requirement usually, so the general recommendations power density is at 0.95W/cm
2Under.If but in fact cast aside the requirement of heating equipment surface temperature, power density can be higher, and higher power density ability is arranged, and means to possess higher fail safe, longer useful life.
3. thermal conversion efficiency is high, because alloy foil sheet and mica substrate fit tightly, the heat conduction is fast, and with planar heating, pure resistor element circuit, the heat efficiency is up to more than 98%.
4. structural stability is good, and alloy foil sheet, mica cross gummed paper and high temperature adhesive forms the alloy foil sheet adhesion-tight by the compacting of high-temperature laminating technique.Particularly alloy foil sheet has the distinctive toughness of metal and flexible, and the various physical influence that can bear normal production and be difficult in transit avoid can be shockproof.
5. power stability is good, not decay during normal service life.
6. quick heating, heating equipment can reach full heat in 1 ~ 2 minute.
7. heat transfer type is comprehensive, can make respectively the Electric radiant Heating Film that possesses hot-air convection and infrared radiation dual mode, and heating effect more comprehensively.
8. thermal source is soft, not hot-tempered heat, and oxygen consumption does not reduce air humidity, and the body heating is more comfortable.
9. noiselessness, free from extraneous odour, without light pollution, environmentally-friendly sanitary, suitable high-quality life requirement.
10. be easy to temperature adjustment control, thermal inertia is little, heats up synchronously, and thermal field is even, is easy to overheated temperature control protection, also can be used for the adverse circumstances heating, such as high humidity environment etc.
11. long service life because the alloy foil sheet circuit is pressed together on and becomes a closed state between the mica, and heater in galvanization without rubescent phenomenon, so there is not oxidizing process, useful life is more than 60000 hours.
