Now many places are using LED display, it can be said that LED display has become a part of the city. However, with the rapid development of this industry, its safety and fire protection application technology has been put on the agenda again, and many domestic display fires have sounded the alarm for the entire LED industry. The following YONGS LED display will introduce to you the factors that affect the fireproof raw materials of LED display.
1. Plastic kit factor: The plastic kit is an important part of the fireproof raw materials of the display screen. Since it is mainly the material used for the bottom shell of the unit panel module mask, the PC+glass fiber material with flame retardant function is used. It not only has flame retardant function, but also can not deform, become brittle and crack under high and low temperature and long-term use. At the same time, it uses glue with good sealing performance, which can effectively prevent rainwater from the external environment from seeping into the interior, thereby avoiding fire caused by short circuits.
2. Wire factor: The larger the unit area of the display screen is, the greater the amount of electricity it uses, so the requirements for the stability of the power supply of the wire are higher. Among many wire products, only the wire that meets the requirements of the national standard can ensure its safety and stability. These requirements must be met when selecting: First, the wire core must be a copper wire conductive carrier. Second, the core cross-sectional area tolerance is within the standard range of values. Finally, the insulation and flame retardancy of the wrapped wire core rubber must meet the standard.
3. Power factor: When choosing a power supply product, only the power supply product that has passed the UL certification is the best choice. Because its effective conversion rate can ensure the safety and stability of the power supply load, it can also work normally in the case of hot external ambient temperature.
4. Factors of external protective structural materials: It is particularly important to select the external protective structural materials of the display screen. Due to the low fire rating of the aluminum composite panel of general outdoor display products, it ages faster with high temperature, rain and cold and thermal shock, so that in the relatively humid climate season, rain and dew easily penetrate into the interior of the screen, which is easy to cause electronic damage. The components are short-circuited, resulting in a fire. Therefore, we must choose the aluminum composite panel with a higher fire rating on the market, so that the fire resistance is excellent, the fire resistance is strong, and the oxygen aging performance of the special material for the core material is also strong, so as to avoid the occurrence of fire.
