Fireproof cable tray is a layer of fireproof coating processed by galvanized cable tray, which has fireproof performance on the surface. Referred to as "fire-proof cable tray" fire-proof cable tray is to spray a layer of fire-proof paint on the surface of ordinary cable tray to play the role of fire prevention and flame retardance! In fact, the cable tray itself will not catch fire, and it can only be the cable that catches fire. The fire retardant principle of fire retardant paint
The protective thickness of fire-proof cable tray shall meet the requirements of table 10 of JB / T 10216-2000 cable tray for electric power distribution, and the plating shall be greater than 12 μ M, hot plating greater than 65 μ M, plastic spraying greater than 50 μ m. Fire protection greater than 500 μ M, which can be measured with a thickness gauge.
1. The difference between fire-proof cable tray and ordinary cable tray is that powder is used differently. Fire prevention needs to be further divided. Ordinary fire-proof powder refers to powder that cannot burn. High temperature resistant powder will not change or fall off under the high temperature of 550 degrees. At present, for the cable tray market, fire prevention means that the powder can not burn, that is, the flame retardant is added. You can test it with an open fire!!
2. Differences between fire-proof cable tray and powder coated cable tray: 1. The fire-proof function of fire-proof cable tray is much higher than that of powder coated cable tray. 2. The powder coated cable tray is the simplest and most basic surface treatment. 3. The cost of fireproof cable tray is high.
3. Fire protection design requirements of installation works; Important parts; Fire proof pillows are filled in the trunking. General; Make fire barriers and fill fire pillows across walls and floors.
4. It is generally used for cable laying in basement, warehouse, machine room and other parts.
