Description
Technical field
The present invention relates to the manufacturing methods of planar heat producing body, are related in more detail, are being attached to based on carbon fiber paper
The copper strips position of above-mentioned carbon fiber paper forms the manufacturing method of the planar heat producing body of multiple perforation.
Background technique
Petroleum and gas heater, storage heater, electric heating heating can be divided into according to the type of the heating machine of insulator
Device, electrothermal heater can be made of near infrared ray heater, radiator, far infra-red heater.
There are the generation of pernicious gas and noise and oil price sharp increase and fire hazards for petroleum and gas heater
The problems such as, there is the ventilation according to convection type in storage heater and the difficult and low thermal efficiency installed is asked
Topic, near infrared ray heater in electrothermal heater is because of the limitation of high fever and shape and there are energy losses due near infrared ray wavelength
Problem, radiator there is a problem of in hot media replacement and installation and processing.
In the past, using electric conductivity carbon paste as pyrotoxin, but this electric conductivity carbon paste to the carbon black of ball shape in order to assign
Continuous electric conductivity and the mode for mixing a variety of binders and electroconductive powder is fabricated, therefore, it is difficult to manufacture to be used for DC hair
The heater of the low-resistance value of hot body.The volume resistance of carbon paste can be for example 500 Ω/㎝, according to the volume of printing and impregnation
Resistance can be 25 μm of 40 Ω/㎝.The heater of this electric conductivity carbon paste is applicable in 80 DEG C or more of temperature long-term fever
When, organic binder included in cream be oxidized and thermalization and there is a problem of that endurance life is short.
In particular, above-mentioned electric conductivity carbon paste is impregnated with realizing by way of such as impregnation with the manufacturing method of coating weaving yarns mode
In mode, after poly- (poly) yarn or cotton yarn are weaved with grid (net) shape, it is dried after being impregnated in carbon ink, utilizes later
The mode that insulant carries out coating processing manufactures electric conductivity carbon paste, substrate-cotton yarn for the fixed carbon liquid as pyrotoxin
Price is high, and the amount of the bonding insulant of upper and lower insulating trip is more due to the lattice shape of the thickness of cotton yarn, and thickness is thick and leads
Price is caused to rise, it is difficult to a small amount of production.
On the other hand, coat in weaving yarns mode, coat conductive compound and carbon ink on the surface of poly- (poly) yarn and
At carbon yarn writhing number thousand and after being weaved (coating of yarn surface), after so that the woven carbon yarn of institute is arranged in regulation apperance, with
By insulant carry out coating or binder-treatment in the way of manufacture electric conductivity carbon paste, because fever member for threadiness, and with existing heat
The difference of quality occurs according to the configuration of the paint-on technique of carbon ink and equipment for line heat generation characteristic having the same, in order to adjust electricity
Resistance and tens of to thousands of yarns are entwined, if a part occurs short-circuit, office caused by existing because of hot spot (hot spot)
Portion's overheat and fire hazard.
Like this, in the past, carbon impregnation woven yarns heater dominates market especially in thin film type heater field, but produces
The quality of product is not stabilized also.
On the other hand, patent document disclosed in following existing technical literature is to be related to the technology of planar heating, for reference.
