METHOD OF MANUFACTURING SHEET TYPE HEATING ELEMENT USING THE INGREDIEUTS OF KOREAN PAPER

摘要

The present invention relates to a method of manufacturing a planar heating element that is used for various heating article having a heating function,; The shut 9-11% by weight of the pulp 60 to 85% by weight of the material after, the mixing step of mixing a car head office 5 to 30% by weight, a binder and 1-5% by weight; Stirring step of putting the mixture was stirred with a stirrer for 1 to 2 hours and; The stirred mixture was pressed into the paper machine paper making process of drying at a temperature of 20 ~ 60 ℃ and; Carbon powder 20 to be precipitated a mixture of 60g / ℓ in water and production process; Precipitation step of the precipitation to be propelled precipitate dispersed carbon powder to adsorb the surface; A drying step to remove the can from the propelled precipitate dried at a temperature of 20 ~ 80 ℃ and; Foundation whether dry heat at a constant size and by attaching a plurality of polar standing so made as electrode installation and coating step of compression coated with a polymer resin,; This is in the nature and tinged with a mild (Avg. PH7.0) so good adsorption capacity and excellent gyeolchakryeok carbon Inc., the heating element made by using this, there is no color variation can be obtained a long life and excellent heat generating performance of the planar heating element product .
