■ In the background

As the thermal paper is widely used in retail, gaming, finance, logistics, clothing, medical and other fields, in order to meet a variety of applications, formulation and coating are also different, for example, in order to improve the effect of coating colorants and thermosensitive base paper sizing agent is added, the adhesive paper (Sticking) etc..

■The generating mechanism of - adhesive paper

Thermosensitive printer can print thin hair under heat or insufficient heat or too fast cooling speed, heat sensitive paper sticking to printing hair or printing, compression and noise, etc. under certain conditions such as low temperature or high humidity, etc., the phenomenon of sticky paper (Sticking). See Figure 1 heat sensitive paper color reaction and diagram 2 TPH printing.

■ - Sticky phenomenon

When the thermal printer is in normal printing, the paper is evenly distributed, and the print pattern is evenly distributed. When the paper is stuck, the paper is fast.

Slow, print pattern is also different, accompanied by greater noise, the specific figure 3.

■ - influencing factors

According to the degree of influence from big to small in turn is: the thermal medium characteristics, environmental temperature and humidity, printer structure and proofs,

Heat sensitive printing head structure, printing speed, pressure and so on.

■In the improvement of adhesive paper

We can reduce the noise by adjusting the section structure of the thermosensitive print head so that the paper and the print head are easier to peel off.

Sound. However, the main source of the adhesive paper still lies in the characteristics of the thermosensitive medium, in order to compare the differences between different media.

We have carried out a comparative experiment on carbon deposition at home and abroad, and the results of 3 representative paper experiments are shown in Table 2.

The thermal sensitive layer and the top coat of heat sensitive paper have great influence on STICKING PHENOMENON, which is mainly due to the temperature resistance of the organic components contained in the top coat, and the use of inorganic components such as lubricants in the thermal sensitive layer, which will cause STICKING at that time.

summary

From the test results of 3 kinds of paper, we can see that the difference of different heat sensitive paper is very big, which shows that the improvement space is also great.

The thermosensitive printing head itself is improved from the characteristics and the printer can be improved from the setting conditions to reduce the sticky paper phenomenon, but Gai Shancheng

It is very necessary to improve the paper from the heat sensitive paper, which can not be completely eliminated from the root of the paper.

The major printer manufacturers in China have found more and more problems of carbon and paper sticking, which are increasingly serious and seriously affected.

The normal print even destroys the print head. International Korean customers, Japanese customers, the Bank of Malaysia, the Bank of Thailand, etc.

Starting to complain about the problem of carbon deposition and sticky paper, the quality of paper is imminent.
