What is the analysis of LED display fire protection technology?

How to do a good job of fire prevention in LED display, the quality of fire protection technology of the display screen is mainly related to the display fire protection raw materials and box technology. Fireproof raw materials mainly include the wires used inside the display screen, power supply, external protective structure fireproof materials and plastic kits: in most display applications, the larger the unit area of the display, the greater its power consumption, and the higher the requirements for the power-on stability of the wire.

Among many wire products, the use of wire rod that meets the requirements of the national standard can ensure its safety and stability, and its requirements have three points: the wire core is a copper wire conductive carrier, the core cross-sectional area tolerance is in the standard range, and the insulation and flame retardancy of the rubber covering the wire core meet the standard.

With the rapid development of modern science and technology, China's LED display industry has also been continuously growing, and the scale of the industry is also expanding, however, in the selection of Hong Kong Yijun Hotel sudden fire incident, to the entire LED industry sounded a wake-up call, in the rapid development of the same time, should also pay attention to safety issues. Henan Mingxinyuan Science and Technology **** relevant personnel pointed out that the fireproof raw materials mainly include the power supply, wire, external protective structure fireproof materials and plastic kits used inside the display screen

The first point: UL certified power supply products are also the best choice when choosing similar products, its effective conversion rate can ensure the safety and stability of the power supply load, and can work normally in the case of hot external ambient temperature. The second point:

Plastic kit, plastic kit is mainly the material used in the bottom shell of the unit module mask, the main raw material is pc + glass fiber material with flame retardant function, which not only has flame retardant function, but also can not be deformed and will not become brittle and crack when used at high and low temperatures and for a long time, and at the same time, combined with the use of glue with good sealing, it can effectively block the rainwater from the external environment from penetrating into the interior and causing a short circuit and fire. The third point: in terms of the material of the external protective structure of the display, most of the display products with high fire rating on the market are made of fireproof aluminum-plastic panels, which have excellent fire resistance, strong fire retardant, and strong oxygen aging performance of special materials for core materials.

The fourth point: in most display applications, the larger the unit area of the display, the greater its power consumption, and the higher the requirements for the power-on stability of the wire. Among many wire products, the use of wire that meets the requirements of the national standard can ensure its safety and stability.

The above are the internal reasons of the display, in the process of use, the later maintenance is also very important, the operator only in strict accordance with the process of operation, in order to reduce the fire of the LED display.

I myself do this part of the LED screen, 1: In most display screen applications, the larger the unit area of the display screen, the greater its power consumption, and the higher the requirements for the power-on stability of the wire. Among the many wire products, the use of wire rods that meet the requirements of the national standard can ensure its safety and stability, and its requirements have three points:

The wire core is a copper wire conductive carrier, the core cross-sectional area tolerance is in the standard range, and the insulation and flame retardancy of the rubber wrapping the wire core meet the standard.

2: The power supply products that have passed the UL certification are also the best choice when choosing similar products, and its effective conversion rate can ensure the safety and stability of the power supply load, and can also work normally in the case of hot external ambient temperature;

3: In terms of the material of the external protective structure of the display screen, most of the display curtain products with high fire rating on the market are made of fireproof aluminum-plastic panel, which has excellent fire resistance, strong fire retardant, and strong oxygen aging performance of the special material for the core material, melting point temperature 135, decomposition temperature 300, environmental performance, low smoke and halogen-free, in line with SGS, flame retardant B-S1, D0, T0, reference standard UL94, GB 8624-2006. The aluminum-plastic panel of general outdoor display screen products ages rapidly with high temperature, rain and cold thermal shock, so that in the relatively humid climate season, rain and dew are easy to penetrate into the inside of the screen, resulting in short circuit of electronic components.

4: There is an important part of the display screen fire prevention raw materials, that is, the plastic kit, the plastic kit is mainly the material used in the bottom shell of the unit module mask, the main raw material is the PC + glass fiber material with flame retardant function, which not only has the flame retardant function, but also can be used at high and low temperatures and for a long time, it will not be deformed, will not become brittle and cracked, and at the same time, combined with the use of glue with good sealing, it can effectively block the rainwater of the external environment from penetrating into the interior and causing a short circuit and fire.

Pure**, hope to help you.

I don't seem to have heard of this, check the fire resistance of the materials used, and whether there are special refractories.

The fire performance of the display is mainly related to the two aspects of the display fire protection raw materials and the box process. The four major factors that affect the fire protection raw materials of the display are:

Clause. 1. Plastic kit factors.

The plastic kit is an important part of the fireproof raw materials for the display screen, because it is mainly the material used in the bottom shell of the unit board module mask, so the PC+ glass fiber material with flame retardant function is used. Not only is it flame retardant, but it also does not deform, brittle, or crack at high and low temperatures and when used for a long time. At the same time, it uses a glue with good sealing, which can effectively block the rainwater from the external environment from penetrating into the interior, so as to avoid fire caused by short circuit.

Clause. Second, the wire factor.

The larger the unit area of the display, the greater the amount of electricity it uses, and the higher the requirements for the power-on stability of the cable. Among the many wire products, only the use of wire that meets the requirements of the national standard can ensure its safety and stability. These requirements must be met at the time of selection:

First of all, the core of the wire must be a copper wire conductive carrier. Secondly, the core cross-sectional area tolerance is within the standard range value. Finally, the insulation and flame retardancy of the wrapping core rubber should meet the standard.

Clause. Third, the power factor.

When choosing power supply products, only power products that have passed the relevant professional quality certification are the best choice. Because its effective conversion rate can ensure the safety and stability of the power supply load, it can also work normally even when the external ambient temperature is hot.

Clause. Fourth, the external protective structure material factors.

It is particularly important in the selection of materials for the external protective structure of the display. Due to the low fire rating of aluminum-plastic panels for general outdoor display products, it ages faster with high temperature, rain and cold thermal shock, making it easy for rain and dew to penetrate into the inside of the screen in the humid climate season, which can easily lead to short circuit of electronic components and lead to disasters. Therefore, we need to choose aluminum-plastic panels with high fire resistance on the market, so that the fire resistance is excellent, the fire retardant 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.

Hello, from Xunwei technical articles, we learned that the fireproof raw materials of LED display mainly include the wire, power supply, external protective structure, fireproof materials and plastic kits used inside the LED display.
