Knowledge Base

Q

Fire safety is crucial in modern architecture and industrial fields. L-type inorganic fireproof partition, as a key fireproof material, is gradually becoming the preferred choice for many engineering projects. Below is a detailed introduction to its outstanding selling points. Excellent fire resistance performance L-type inorganic fireproof partitions have extremely high fire resistance limits. After professional testing, it can maintain stability in high-temperature environments for a long time

Q

L-type inorganic fireproof partitions have a wide range of application scenarios. In the power industry, fire separation is commonly used for cable trays to prevent flames and smoke from spreading along the trays during cable fires, ensuring the safe operation of the power system, such as in cable laying areas in substations, power plants, and other places.

Q

The inorganic L-shaped fireproof partition is processed and formed from inorganic non combustible materials, with an overall L-shaped integrated structure composed of vertical and horizontal board surfaces. It has a wide range of specifications and can be cut and spliced according to the on-site size. The board material is uniform, the structural strength is stable, and it is resistant to moisture and aging under normal conditions. It is not easily deformed or powdered in environments with temperature and humidity fluctuations.
