Fireproof mud type fireproof mud use
Fireproof mud has good plasticity, acid resistance, alkali resistance, corrosion resistance, construction and maintenance more convenient, and can be combined with other plugging materials (such as fireproof package, etc.). Organic fire blocking materials are suitable for plugging holes in industrial and mining enterprises, high-rise buildings, shipbuilding, metallurgy, power generation, wires and cables in post and telecommunications, etc. to prevent the flame from spreading from the hole to the neighboring room during a fire. The following Xiao Bian introduces the model of fire prevention mud and the use of fire prevention mud. Fireproof mud model Fire-resistant mud is divided into primary, secondary and tertiary according to the fire-resistant limit. It can also be said to be its model grade, which is mainly composed of high-alumina bauxite, magnesia, silica and other chemical materials, but seeing these components can not see its performance. After mixing fireproof mud, it has anti-corrosion. , fire resistance, oil resistance, waterproof and other properties, in the event of cable and wire fire, you can use it to block, to prevent the spread of fire, reduce life and property losses. The CP25WB+ fire-resistant mud is slightly different from the above models. It is a synthetic elastomer advanced latex which can be used alone and does not need to be used in combination with other fireproof materials. It can be used to block the spread of fire, smoke, toxic gases and water. CP25WB+ fireproof mud is easy to expand when exposed to heat, and it has bond strength, caulking rate and no vertical flow. Fireproof mud use 1. The gaps around the pipes passing through the firewall or floor are not filled with non-combustible materials. If these through openings and gaps are not fireproofed, in the event of a fire, flames and fumes will spread through these through openings and gaps, and star fires may cause huge damage to property. 2. The cable and pipe wells pass through the floor and are not fire-proofed with non-combustion bodies equivalent to the fire limit of the floor in accordance with the requirements of the code. Holes communicating with rooms, walkways, etc. are not filled with non-combustible materials. Some were not carefully separated or compacted after the pipeline was overhauled. 3. Some fireproof mud is not sealed to the top, leaving voids or holes. There is also a variety of structural gaps between floors and walls, walls and walls. The so-called building fire prevention and plugging system is a full-scale plugging of these structural openings and cracks to prevent the spread of smoke and fire. Fireproof mud density Fireproof mud is generally divided into several types according to different densities, namely DR-A3-JH-1 and DR-A3-JH-2. In terms of widely used functions, the difference between the two is not very great. DR-A3-JH-2 is often used as a hole plugging material for wire and cable, while DR-A3-JH-1 is widely used in power plants, industrial and mining enterprises, high-rise buildings, shipbuilding power and so on. The density of DR-A3-JH-1 is 1.7~2.0T/m^3, and the density of DR-A3-JH-2 is about 2.0T/m^3. The density of DR-A3-JH-1 is larger than that of the former. Fireproof mud performance index Appearance: plastic solid, with a certain degree of weakness Density: 2.0 x 10 cubic kg/m3 Water resistance: ≥3d? No swelling Oil resistance: ≥3d? No swelling Corrosive: ≥7d Fire-resistance: fire-resistant material of Class 1 fire-proof material ≥180min Editor's summary: The fireproof mud model and the use of fireproof mud were introduced here. I hope to help everyone. If you want to know more about yourself, you can follow the information on this site.
