The application of thein the lottery

Lottery thermal paper

The principle of making thermosensitive paper is to coat fine powder on the base of ordinary paper, the composition is colorless dyestuff phenol or other acidic substances, separated by thin film, under heated conditions, the film melts, powder mixed to show color reaction, the handwriting on thermistor paper is unstable, easy to fade, it caused the document content to be illegible.

Triple-proof thermosensitive paper is generally used in lottery industry.

Triple-proof thermosensitive paper; Thermosensitive electronic scale paper is generally divided into three layers: the first layer is a paper-base, the second is thermal sensitive coating, the third layer is a protective layer. The thermal sensitive coating or protective layer mainly affects the quality of the paper, if the coating of the thermally sensitive electronic scale paper is not uniform, it would cause some places to be dark, some places are light in color when printed, the quality of print is obviously reduced, if the chemical formula of the thermosensitive coating is not reasonable, it wouldresult in a very short storage time for thermosensitive printing paper, good printing paper can be saved for 5 years after printing( At room temperature, avoiding direct sunlight) Now you can save 10 years of long-acting heat-sensitive paper, but if the formulation of the thermosensitive coating is unreasonable, thermosensitive printing paper may only be kept for a few months.
