What is the specific composition of fireproof mud What is fireproof mud?

The commonly used varieties are as follows: Antimony trioxide. It must be used in tandem with organic flame retardant materials.

Magnesium hydroxide, aluminum hydroxide. They can be used separately, but they are added in large quantities and are often equivalent to the amount of resin.

Inorganic phosphorus. Commonly used red phosphorus and sulfate, pure red phosphorus is finally miniaturized before use, can be used alone and in combination, phosphate has ammonium phosphate, ammonium nitrate, etc.

Boron flame retardant materials. Zinc borate hydrate is commonly used, which is generally used in conjunction with other flame retardant materials. Other metal oxides, such as metal aluminide, metal ferrite, etc., are mainly used for gunsmoke.

Metal halides. Such as all kinds of antimony halides.

First, the specific composition of fireproof mud:

Chlorinated paraffin, china clay powder, unspoiled feldspar, quartz, iron ore and other fragments of rock as china clay.

Second, the main use of fireproof mud:

The material is mainly used to seal the holes of wires and cables to prevent wires and cables from spreading from the holes to adjacent rooms in the event of fires and reduce fire losses. To avoid the expansion of accidents, it has the functions of smoke prevention, fire prevention, and dust prevention. Therefore, the plugging material is widely used in power plants, industrial and mining enterprises, high-rise buildings, shipbuilding electric power, post and telecommunications, substations, metallurgy and other system engineering vertical and horizontal wires, cable through hole plugging.

Most of the main raw materials are high alumina, magnesia, silica, etc.

The use of fireproof mud is mainly used in the power generation of a wire and cable, in the use of the fireproof mud to knead evenly, in the general low temperature situation fireproof mud will be hard, not easy to soft, so it needs to be heated when the softness of the use again. After kneading the fireproof mud, it can be filled in the holes in the wires and cables. It is not a single when using fireproof mud, it is generally used with fireproof package, when the hole is sealed, its sealing thickness is 15 cm, and the fire-resistant time can reach more than three hours.

The thickness of the fill will also vary in the degree of combustion, and the thicker the thickness, the longer it will burn.

Fireproof mud is a product used for fire prevention, and the main purpose is to play a role in fire prevention. Fireproof mud is a flexible flame retardant material, which can effectively prevent flame burning, and it is also very long in fire resistance. Fireproof mud has many advantages, from the appearance of fireproof mud belongs to a plastic solid substance, and has a certain flexibility, it has a fire resistance can reach a fireproof plugging material, which shows that its fire resistance is very good, in terms of water and oil resistance also has a good performance, and will not produce swelling phenomenon.

Fireproof mud is a kind of flexible flame retardant material, also known as flexible organic plugging material, plastic fireproof plugging material, and also has the characteristics of fire resistance, high temperature resistance, low smoke generation, etc., and must also have a very good acid resistance, alkali resistance, corrosion resistance, and plasticity.

It is composed of refractory powder, binder and admixture.

Almost all refractory raw materials can be made into powders for the preparation of refractory muds. The refractory clinker powder and an appropriate amount of plastic clay are used as binding agents and plasticizers to make ordinary refractory clay, which has low strength at room temperature and high strength when forming ceramic bonding at high temperature. Chemically bonded refractory mud with waterhard, gas-hard or hot-hard bonded materials as bonding agents is called chemically bonded refractory mud, which produces a certain chemical reaction and hardens before it is lower than the bonding temperature of the ceramic.

The particle size of refractory mud varies according to the requirements of use, and its limit particle size is generally less than 1mm, and some are smaller or finer. The material of refractory mud should be considered to be consistent with the material of refractory products of masonry. In addition to being used as a joint material, refractory mud can also be used as a protective coating for the lining by smearing or spraying.

Types of refractory mud:

1. Ceramic combined refractory mud It is a mixture composed of refractory fine aggregate and ceramic bond (plastic clay). Delivered dry, water added, hardened by ceramic bonding at high temperatures.

2. Hydraulic bonded refractory mud is a mixture composed of refractory fine aggregate and hydraulic bond (cement) that plays a major binding role. Delivered in dry condition, it can be used with water and does not need to be heated when hardening.

3. Chemically bonded refractory mud is a mixture composed of refractory fine aggregate and chemical binder (inorganic, organic-inorganic, organic). The delivery condition can be both slurry and dry, hardening below the ceramic bonding temperature. According to the hardening temperature, this refractory mud can be divided into two types: air hardness and hot hardness.

Gas-hard refractory mud is often prepared with gas-hard binders such as water glass. Hot-hard refractory mud is often formulated with a hot-hard binder such as phosphoric acid or phosphate. After hardening, this kind of hot-hard refractory mud not only has high strength at various temperatures, but also has the characteristics of small shrinkage, tight joints and strong corrosion resistance.

1. How to use fireproof mud?

Fireproof mud is mainly used in the power generation of a wire and cable, in the use of the fireproof mud to knead evenly, in the general low temperature situation fireproof mud will be hard, not easy to become soft, then it needs to be heated, it can be placed in about 40-70 degrees of warm water, when the softness appears, and then use, and then the fireproof mud kneaded evenly and then fill it in the hole of the wire and cable.

2. What is fireproof mud?

Fireproof mud is a flexible flame retardant material, its appearance is a plastic solid, with a certain weak type, at the same time, fireproof mud has good fire resistance, smoke blocking, oil resistance, water resistance, corrosion resistance, but also has the characteristics of high fire resistance limit, low smoke and so on.

3. What are the precautions for the use of fireproof mud?

1. Before construction, clean up the dust and oil on the surface of the construction.

2. Bishou passes the cable bundle through the hole, evenly separates and pastes the cable with plugging material, and then fills the gap between the cable and the hole wall with plugging material. The thickness of the plugging material should be consistent with the depth of the hole.

3. For larger holes or gaps, it can be found that the fire net is used as a skeleton or reinforced with steel bars, and the support strength has been increased.

4. In order to achieve heat dissipation such as cable penetrations, it is not necessary to block tightly during construction. When a fire occurs, the number of plugging materials is heated and expanded, and the gaps can be plugged tightly, so as to effectively spread fire and smoke.
