Is thermal paper toxic? How to prevent it? Thermal paper, no doubt, is already an indispensable paper in daily life; recently, various media have reported that thermal paper is toxic, and it is necessary for Xiaobian to make a scientific popularization of this matter. Thermal paper is a truth; to understand whether thermal paper is poisonous, we need to understand the construction principle of thermal paper.
Thermal paper mainly prints text images by thermal coating. Thermally sensitive coatings are primarily color developing agents. These are all chemical substances that are not really good for the human body. There is no poison to the human body is not big, but also mainly look at thermal paper manufacturers, because the country does not have the standard of standard thermal paper, some thermal paper manufacturers many of these chemicals make the thermal paper unhealthy, we probably Calling on the country to issue the national standard as soon as possible, there are standards for thermal paper manufacturers. However, the thermal paper has no advantages to the human body and does not mean that it is not used. For example, the computer also has radiation to the human body. However, we are still using it. It is still expected that the country can introduce the national standard. The manufacturer is the best. With three-proof, there is a layer of maintenance coating on the heat-sensitive coating. This coating has a waterproof, oil-proof and scratch-resistant effect, and can be directly touched by a paper hand and a heat-sensitive coating. However, at this stage, quite a lot of manufacturers' general thermal papers pretend to be three-proof thermal paper. It is best to purchase three anti-thermal papers to see the parameters of their thermal paper.
Thermal paper is rich in bisphenol A. "Bisphenol A" does have certain toxicity. Those with open wounds should not touch paper such as thermal paper. Advanced thermal paper is non-toxic, and white paper can replace it. In our days, low-grade bisphenol A-containing thermal papers are still ubiquitous. However, don't be too scared.
Some experts have shown that bisphenol A is attributed to low-toxic chemicals. It is very stable at room temperature, and it will bring health risks to the body when it reaches a certain dose. Beijing Xiangyang Hospital also stated in its official Weibo that bisphenol A will not be released at temperatures above 100 °C. Therefore, the bisphenol A in the usual small ticket is still relatively stable, not too nervous, as long as you pay attention to the details of the day in normal days, it can be useful to prevent.
So, how can we prevent bisphenol A from invading our body and reducing damage through shopping tickets?
1. Don't let the child touch the receipt in case they put the receipt in the entrance.
2. Keep the printed receipt separately in the envelope to avoid other things from infecting the bisphenol A component.
3. When using ATM machines to withdraw money or refueling at self-service gas stations, do not print receipts as much as possible, and try to reduce the timing of touching such receipts.
4, the best small ticket is completely printed out, touched after the temperature is lowered, when sweating or when there is trauma on the hand, try to prevent touching the thermal paper, especially do not hold the thermal paper receipt tightly in the palm of your hand, avoid When the hands sweat, the pores open and the possibility of adding bisphenol A into the body through the pores.
5. The printed receipt is not very useful. It is recommended to throw it away as soon as possible. Since acetone and phenol in bisphenol A are volatile substances, if they are placed in the local area that the human body can touch for a long time, it will cause damage to the human body.
6. After touching the receipt, wash your hands and then eat. Because acetone is water-soluble, it can be taken away during the washing process. But don't wash your hands with alcohol-containing liquids, because alcohol can add to the skin's absorption of bisphenol A.
