The article mainly introduces the effects of moisture, ozone, mechanical stress, light, temperature and other factors on the performance of rubber sheets, and reminds people to be particularly careful during the installation, storage and use of rubber sheets.

1. Moisture.

The main aspects of the influence of the water-reducing board are: When the board is left for a long period of time in a humid air or in the presence of bubbles, the structure of the board is formed, which means that the quality of the water-soluble material in the water base is dissolved in the water. In other words, as the water flows through the water, the air bubbles and the atmosphere floods, and under the alternating action of the two parties, they are joined to each other and the atmosphere is flooded. However, under some specific circumstances, moisture loss may cause damage, and aging may be delayed.

2. Odor.

Because odor has a high chemical activity, and its chemical properties are very large. The principle of change is the same, the structure of the structure is expanded, but the effect of the change is transformed into a metamorphosis. When the effect is changed, the force is vertical to the direction of the production, and the force is vertically cleaved.

3. Mechanical stress.

Under the repeated action of mechanical stress, the rubber molecular chain breaks to form free radicals, and an oxidation chain reaction occurs, forming a mechanochemical process. As for which is more intense, the molecular chain breakage or the oxidation reaction, it depends on the environment in which the rubber sheet is located. Moreover, under the action of stress, the rubber sheet will crack.

4. Light.

The shorter the light wave, the greater the energy. The energy of the outermost rays is greater, and the damage effect on the rubber sheet is also great. In addition to directly causing the cracking and cross-linking of the rubber molecular chain, ultraviolet rays can also cause the rubber molecules to become free, triggering and accelerating the oxidation chain reaction. The impact of light on the rubber sheet mainly occurs on the surface of the rubber sheet.

5. Heat.

Too high temperature will cause thermal cracking and thermal crosslinking of rubber. However, the more serious consequence of high temperature is the aging of rubber sheets. This is because too high temperature will accelerate the oxygen diffusion rate and oxidation rate, thereby accelerating the oxidation rate of rubber sheets. This is a common aging phenomenon - thermal oxygen aging.
