Product introduction

1. The heating carbon paste and the far-infrared electric heating film based thereon, its raw material formula includes the following components by weight: 15-20 parts of carbon powder; 10-20 parts of graphite; 5-10 parts of calcium carbide powder; 35 parts of organic carrier ~70 parts; 1~5 parts of dispersant.
2. The organic carrier includes epoxy resin, polyurethane, acrylic resin and ethylene oxalate; the far-infrared electric heating film based on it includes a base film, a heat-generating carbon paste strip, at least two current-carrying strips, The polyester film on the current-carrying strips, the current-carrying strips are arranged parallel to each other and distributed at intervals, and the heat-generating carbon paste strips are coated with the above-mentioned heat-generating carbon paste.
3. The heating carbon paste is made by mixing carbon powder, graphite, calcium carbide powder, organic carrier and dispersant in proportion. On the one hand, it uses an organic carrier composed of epoxy resin, polyurethane, acrylic resin and ethylene oxalate. So that it has the characteristics of low solid content, can be improved in terms of fineness and uniformity, and has good ductility, which is conducive to uniform coating.
