Foam board is one of many boards, mainly used in building walls, roof insulation, cold storage floor heating, etc. But is this kind of board poisonous? What is the price of the foam board ? What are its specific functions? Let's introduce it to you one by one. 1. Is the foam board toxic? Before understanding the price of the foam board, let's give you the popular science. Is this board toxic? In fact, under normal use, this board does not have to worry at all, it is not toxic. But if the board is in a long-term high-temperature environment, it is easy to breed some bacteria, and it will emit a lot of smoke. Therefore, we should avoid using foam board in high temperature and flammable situations. 2. What is the price of foam board? In fact, there are many factors to consider in the price of foam board. Different thickness, different volume and different density, their prices are very different. According to the investigation of the editor, the price of a foam board with a thickness of 3㎠is about six or seven yuan per square meter, but other thicknesses are not very expensive, at most 50 or 60 yuan. Therefore, there is no fixed value for the foam board price based on the actual purchase price. 3. What is the role of foam board a. If the building uses foam board, it will protect the main structure of the building and prolong the service life of the building. This is because the insulation layer of the foam board is placed on the outside of the structure, and then the structure is not easily deformed due to the difference in temperature changes, and the harmful substances in the air and ultraviolet rays are used to erode the building structure. b. The dampness of the building wall can also be improved. In general, indoor heat insulation needs to be provided with a vapor barrier, and the use of external insulation materials can make the temperature permeability much stronger than the main structure of the building itself. In addition, the phenomenon of condensation does not occur inside the wall, so that the temperature of the entire wall of the structural layer is increased, thereby further enhancing the thermal insulation performance of the wall. c. Of course, this kind of board can also help to maintain the stability of the indoor temperature. Since the structural layer with the greater heat storage capacity of the wall is inside the wall, it can maintain the stability of the room temperature very well. It can also increase the usable area of ​​the house, and can also avoid the possibility of secondary decoration damage to the building insulation layer. Editor's conclusion: The above is an introduction to the foam board, how expensive is the foam board, and what is the role of the foam board. After reading the content compiled by the editor, I believe that everyone should have a deeper understanding of this kind of board.

Thermal roll paper
Thermal paper is also called thermal fax paper, thermal recording paper, thermal Copy Paper, and thermal copy paper in Taiwan. Thermal paper is a kind of processed paper, and its manufacturing principle is to coat a layer of "heat sensitive paint" (heat sensitive color change layer) on high-quality base paper.
Although there are more than a dozen chemicals used in this color change layer, there are at least the following compounds: leuco dyes, the dyes are of a wide variety, the most commonly used are fluorescent compounds; the color developer accounts for less than 20%, and the commonly used are double Phenol, p-hydroxybenzoic acid; sensitizers account for less than 10%, which contains benzenesulfonic acid amide compounds; fillers account for less than 50%, commonly used calcium carbonate (fine particles); adhesives account for less than 10%, Such as polyvinyl acetate; stabilizers, such as dibenzoyl terephthalate; lubricants, etc.
Therefore, the process is difficult and the technical requirements are high.
Thermal paper is generally sold in the form of rolls, generally 80mm×Φ60mm, 57mm×Φ50mm and other specifications are the most common. The first number indicates the width of the paper roll, and the back is the diameter. The general error of the width of 1, 2mm will not affect the use, because Printers generally can`t print on the edge
