Acrylic display stands can be the most popular display props on the market, because acrylic sheets have excellent weather resistance, light transmission, (transmittance can reach 92% or more) and so on. However, in real life, there will be a problem when the merchant maintains the acrylic display stand. Will the temperature affect the acrylic display stand? In fact, although acrylic sheets have high temperature resistance, they must be reversed. When the temperature is too high, they will affect the acrylic display frame and ultimately affect the service life of the display.
High temperatures can have the following effects on acrylic display stands:
1. Affect the extension of acrylic:
As the temperature increases, when the elongation rate of the acrylic sheet increases to 11 degrees Celsius, the elongation at break of the acrylic sheet will reach 5.6%. When the temperature exceeds a certain standard, the acrylic sheet will begin to soften and stretch. Yield damage will occur during the process.
2. Affect the hardness of acrylic:
As the temperature increases, the hardness of the acrylic will decrease. In addition, if the load value is larger when the hardness is measured, the measured hardness value will be lower. Within a certain range, the greater the thickness of the acrylic sheet, the higher the measured value. When the thickness reaches a certain level, the measured hardness value will not be significantly improved.
3. Affect the acrylic Poisson ratio:
The temperature will have an effect on the Poisson's ratio of the acrylic display. If the temperature is higher, the effect on the Poisson's ratio will be greater.
4. Acrylic thickness is different, and the impact on the acrylic display stand is also different:
Temperature will have a similar effect on the impact of acrylic products, and as the temperature increases, the movement of the acrylic molecular chain will be enhanced, and the macroscopically manifested as flexibility and impact.
I hope that the merchants who are fortunate enough to see the temperature of the acrylic display stand must pay attention to the temperature, because the temperature will affect the acrylic display stand, which will eventually shorten the service life of the acrylic display stand.
