Description
Technical field
The present invention relates to the preparation method of electric hot plate.
Background technology
Printed carbon ink heater element is divided into low temperature polyester electric heating film, middle temperature epoxy electric hot plate and high temperature mica electric hot plate.One
As for electronics, electrical equipment, industry heating, civil heating and military affairs etc..High-temperature electric heating plate is the Muscovitum that can generate heat after a kind of energising
Heating board.Electric hot plate heat principle be product under the effect of electric current, carbon micel in heater produces " Brownian movement ", carbon
Violent friction and shock occur between molecule, and the heat energy of generation externally transmits with the form of far infrared radiation and convection current, its electricity
More than 98% can be up to the conversion ratio of heat energy.The effect of carbon molecule makes system surfaces be brought rapidly up.By electric hot plate heating plant
Being arranged on metope, heat energy will be continuously by far infrared radiation with to streamed each angle being delivered to room
Fall.Electric hot plate development potentiality is huge, meets low-carbon (LC), economy, environmental protection development trend.Electric hot plate heating system not water consumption, do not take up an area,
Intelligent temperature control, energy-saving material-saving, meet the policy guidance reducing discharging low-carbon (LC), have a extensive future.Especially cause in heating industry extensively
Pay close attention to.
But the temperature difference differs after traditional printed carbon ink heater element (Electric radiant Heating Film, electric hot plate) has the disadvantage that 1, is energized
Bigger: owing to, in typography, aluminum matter ink knife and silica gel print cutter reciprocating conductive carbon ink roll, and conductive carbon ink itself
Because of stirring, viscosity can be declined, mobility increases, and thus results in along with the increase conductive carbon ink of number to be printed leaks through silk screen infiltration
Amount is continuously increased, and causes conductive carbon ink print thickness to increase resistance and reduces, and power increases.Conductive carbon ink-stick resistance from large to small,
The product power that dispatches from the factory is inconsistent, unstable product quality, produces the bigger temperature difference after electric hot plate (film) energising, it is impossible to reach country's mark
Alignment request, between electric hot plate high temperature and low temperature, the temperature difference is up to 10 DEG C；Owing to the electric hot plate high temperature aging power of carbon ink that works long hours goes out
Now decay.Power increase when the current solution of this series products is printing, first obtains the electric hot plate that power does not waits, then manual
Some carbon ink bars of drop reach design power.The second way is to mark the power number recorded on product, but a collection of product
The product power that dispatches from the factory is inconsistent, affects corporate image.2, power attenuation: carbon ink bonding carrier heatproof is inadequate, the bonding load of existing carbon ink
Body is epoxy resin board, its maximum operating temperature 120 degree, and wall warms up warmer requirement heater operating temperature 180～200 DEG C long
Time service, such state interior wall warms up product power and is just made very small general at 300～500 watts, operating temperature below 80 degree, one
Individual room needs to fill 3～6 walls and warms up, and the not enough indoor decorative effect that simultaneously affects of the too many metope of quantity, poor practicability, user is not
Accreditation.Power attenuation problem by changing product or can only be accelerated.
