Fireproof clay models can also be divided into two types: expansion type and non expansion type. Strong plasticity and flexibility; In large engineering projects such as industrial and mining enterprises, shipbuilding and power, postal and telecommunications, metallurgy, etc., vertical and horizontal wire and cable penetration holes are often sealed. We can see that many electrical appliances are equipped with insulated plastic covers to prevent accidents. The function of fireproof mud is basically similar to that of insulated covers, but it is better than insulated plastic covers. When using all electrical appliances, care should be taken.
Low temperature fire-resistant mud models can replace these insulation covers and effectively prevent the occurrence of danger.
Fireproof mud is slightly different from the above models. It is a synthetic advanced latex of elastic material that can be used alone without the 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.
Fireproof blocking materials will harden and eventually become solids in different states; Non hardened fireproof mud will not change even after a long time and will remain unchanged. Due to their different chemical compositions, organic fireproof mud can be divided into organic fireproof mud and inorganic fireproof mud. Among them, organic fireproof mud has limited temperature resistance after solidification, but can still be cracked or burned, while inorganic fireproof mud is the opposite. Inorganic fireproof mud cannot undergo any other treatment, but has high temperature resistance. Fireproof mud is a flexible flame-retardant material, also known as flexible organic blocking material or plastic fireproof blocking material. Commonly used for sealing holes in wire and cable construction.
Fireproof clay is prone to expansion when exposed to heat, and has bonding strength, joint filling rate, and no vertical flow retention. Regardless of the type of fireproof clay, there are significant differences in its properties and characteristics. Based on its properties, we can further distinguish it.
1. According to their different properties, fireproof clay can be divided into hardened fireproof clay and non hardened fireproof clay. The characteristic of hardened fireproof clay is that under certain conditions, it will harden into different solid states; Non hardened fireproof mud will not change even after a long time and will remain unchanged.
2. Due to their different chemical compositions, organic fireproof mud can be divided into organic fireproof mud and inorganic fireproof mud. Among them, organic fireproof mud has limited temperature resistance after solidification, but can still be cracked or burned, while inorganic fireproof mud is the opposite. Inorganic fireproof mud cannot undergo any other treatment, but has high temperature resistance.
How to purchase high-quality fireproof mud:
1. Look at the appearance. Qualified fireproof mud has a solid appearance and a certain degree of softness, while unqualified fireproof mud is mostly relatively hard. 2. Check the water resistance. If the qualified fireproof mud of Hubei fireproof mud is soaked in oil for 3 days without swelling, it is also a good reference standard. 4. Check the anti-corrosion performance. If there is no corrosion phenomenon in the fireproof mud test for 7 days, it also means that the fireproof mud is qualified. 5. Check the fire resistance. The fire resistance of high-quality fireproof mud manufacturers is the main characteristic of fireproof mud, and the quality of fireproof mud is directly determined by the quality of this performance. Therefore, the reference standard of whether the fireproof mud is qualified is also indispensable. If in the fire resistance test, the fire-resistant mud has been tested for 3 hours without any flames penetrating the back fire surface, and is intact without cracks, then this fire-resistant mud is definitely qualified and you can use it with confidence.
The main technical indicators of fire-resistant mud from organic blocking material manufacturers are: 1. Fire resistance performance: oxygen index: 70%, fire resistance time: 180min. 2. Physical and chemical properties: Appearance: reddish brown plastic solid. The usage method of fireproof mud: Mix the organic blocking material evenly and embed it into the hole. The organic blocking material will be harder at low temperatures. At this time, the blocking material can be placed in warm water at around 50 degrees Celsius and heated until slightly soft before use.
Today, I will talk to you about how to use fireproof mud correctly. When using fireproof mud for sealing, it is necessary to clean the sealed holes and other debris. Then the cable bundle or optical cable passes through the hole, evenly separates and sticks the cable or optical cable with fireproof mud, and then fills the gaps between the cable and the hole wall tightly with blocking material. The thickness of the filling material should be consistent with the depth of the hole; For larger holes, it can be used in conjunction with inorganic plugs or flame arresters.National standard fireproof mud manufacturer
