1. Flame retardant lighting tiles are mainly used in steel mills and blast furnaces with high temperature, fire splash or some special occasions with flame retardant requirements.
two. , The flame retardant series lighting boards currently produced by our company are divided into two types: primary flame retardant (F1 grade, oxygen index>30) and secondary flame retardant (F2 grade, oxygen index>26). The primary flame retardant lighting board is produced by using the resin containing flame retardant components in the molecular structure (also called reactive flame retardant resin); the secondary flame retardant resin lighting board is produced with flame retardant additives (also called additive flame retardant). burning resin).
3. Flame retardant lighting panels, compared with general lighting tiles, have slightly poorer aging resistance and yellowing resistance due to the presence of flame retardant components in the resin material. After testing, the first-level flame retardant lighting tile will show signs of yellowing after one year, and the second-level flame-retardant light-transmitting tile will show slight yellowing (second-level flame retardant is easier to yellow than first-level flame retardant), and the follow-up The yellowing will become more pronounced over time.
To sum up: the flame retardant lighting board is more likely to turn yellow than the general lighting board, but it will not affect the quality, but the light transmittance will decrease with the increase of the service life, and there is no guarantee that the light transmittance will only be lost during the service life. 3% to 10% only. However, yellowing does not mean the end of the life of the lighting board, and the mechanical properties such as the mechanical strength of the lighting board are basically unchanged, which can still meet the requirements of its use!
Flame retardancy of lighting tiles
The performance of lighting tiles is very high, but do you know the flame retardant properties of lighting tiles?
1. The oxygen index of flame retardant lighting tile is greater than 26, which can achieve secondary flame retardant. If the oxygen index is greater than 30, it can achieve primary flame retardant.
2. Both general-purpose and economical series lighting tiles are flammable (oxygen index is about 20); they can burn quickly in the event of a fire, forming a smoke exhaust belt, and no melting droplets are produced when burning.
