- What are the applications of graphite rods besides fire-proof expansion rods?

2023-01-14 14:26

1. Fireproof expansion rod

Because of its expansibility, high temperature resistance and thermal insulation, it has become an excellent sealing material and is widely used. At present, there are two main forms of fireproof expansion rod: one is the expandable graphite and rubber materials, inorganic flame retardant, accelerator, vulcanizing agent, reinforcing agent for mixing, molding into various specifications of expansion seals. Mainly used for fireproof doors, fireproof glass Windows and other occasions. The expansion bar acts as a barrier to the flow of smoke throughout the fire. Another kind of fireproof expansion rod is based on glass fiber as the carrier using some kind of adhesive will be expandable graphite bonding on the carrier is mainly used in the manufacture of fire doors.

2, fireproof package, fireproof plugging material, fireproof ring

Because the expansible graphite has a high expansion rate under high temperature conditions, it can be made of fireproof package, fireproof plugging material, as an effective expansion flame retardant material, used for fire blocking in buildings. Such as sealing building pipeline, in the cable, gas pipeline fire to prevent the spread of fire.

3. Fire proof board

Due to the small density of expandable graphite, crystal stability, often used in fireproof board mix, the purpose is to increase the fire performance of the board, reduce the density of the board, enhance the heat insulation performance. Expanded graphite is often developed into thin sheets for use. This material can be used to make flame retardant panels for walls and other combustible substrates. In this use, natural flake graphite particles of small size can be used as the initial raw material and directly pressed into plates.

4, flame retardant coating

In recent years, expandable graphite has been tried to be used in flame retardant coatings. It makes coatings have excellent thermal expansibility. The United States recently proposed a flame retardant coating composed of fiber reinforced material, expandable graphite, solid heat-absorbing material, polymer binder, etc., which can be used for sewer coating of fiberboard and wood. The paint overcomes the previous paint easy to produce smoke shortage. In the fire can be rapidly expanded to form a light carbon layer, and the release of toxic gas (such as: SO2, NO, etc.) less. It can effectively protect the substrate against fire. But the black surface of graphite limits its widespread use. The focus of this research is to change its color by surface modification, increase the color variety of coatings, and make its color acceptable to the public.

5, flame retardant plastics

The expanded carbonized layer formed by expandable graphite carbon has excellent heat insulation and high temperature resistance. The application of expandable graphite in flame-retardant plastics is mainly based on its expansibility and adiabatic property. For example, the expansion of graphite sheets dispersed in polyurethane foam can prevent combustion, reduce the fire, but also play a role in heat insulation.

- Brief description of fireproof expansion seals for clad doors and Windows

At the present stage of the refractory doors and Windows market, the fire Windows that can meet the fire resistance for 1 hour are basically steel frame or steel and wood composite frame plus composite fire glass in principle. Therefore, the aging performance is poor. Because the steel frame is not extruded, it can not meet the sealing requirements of air tightness, water tightness and so on. In addition, there is the temperature sense window closure of ordinary fire Windows are external, very affect the architectural beauty, difficult to popularize in large areas of residential buildings, and the current use of ordinary broken bridge aluminum Windows, so the fire time can not reach the requirement of 1 hour.

- Brief description of fireproof expansion seals for clad doors and Windows

Coated doors and Windows fireproof expansion seal is made of PE outer coating, high resilience PU foam as the main raw material, containing PP skeleton, so the fireproof expansion seal has less than 10% compression change form, to ensure that it can be applied in doors and Windows, coated fireproof expansion seal sealing, PE outer coating greatly increase the service life of the product, Not only the color is rich and gorgeous, but also there are more choices. The PP skeleton in this material also has a very good fixed effect on the product, which can effectively prevent the product shrinkage after successful installation.

- Cause of abnormal sound after installation of aluminum alloy fire window

Have you ever had this problem? There is no problem for users who live in high-rise buildings to check the aluminum alloy fire Windows after the developers hand over the room, but the wind will ring, causing a lot of trouble, and the sound like blowing whistle continues to spread to the ears, which is almost a collapse. Most residents have changed the Windows, but there are also some who feel that they can make do with it, and the sound continues like this, so where is the problem? What's the solution? Aluminum alloy fire window such a problem we have to check, see is the wind or the window resonance sound, is generally not well sealed, window frame and glass edge gap, the simple solution is to stick a wool can be, there is the whole window frame edge sealant, so as to effectively reduce the resonance sound. So now check in or buy aluminum alloy window friends pay attention to this problem, find professionals to install Windows, seal must do a good job, can protect our life and property safety and no noise harassment, customized aluminum alloy fire Windows suggest you choose regular manufacturers cooperation, not only quality assurance installation worry-free, factory price is also appropriate, welcome to consult us.

- Describes the fireproof expansion strip

We all know that fireproof window is a kind of fireproof glass window that meets both fire integrity and heat insulation integrity. Fireproof window is a whole composed of fireproof glass, frame, fireproof expansion bar and so on. They work together to ensure the complete performance of fireproof window. This shows the importance of fireproof expansion tape.

- How to select high quality fire window profiles

First of all, Xiaobian first to tell you, what is the fire window profile. Fire window refers to the window that can meet the requirements of fire stability and fire integrity in a certain period of time, together with the frame. Fire Windows should be installed on the outer walls of two buildings with insufficient fire spacing, or between Spaces separated by firewalls, when lighting and ventilation are needed. The main function of fire Windows is to isolate and prevent the spread of fire, this kind of Windows are mostly fixed Windows. Another function is to light the house. This type of window has movable sashes to light and ventilate the house normally. In case of fire, it can play the role of fire prevention and separation. Fire Windows with movable sashes shall have manual and automatic closing functions. Therefore, it is very important to choose the fireproof window profile with excellent quality.
