Fire Proof Seal Has A Good Bonding Performance
Jul 11, 2017

Silicone Fire Proof Seal is a kind of room temperature vulcanized silicone rubber, which is made of terminal hydroxyl polydimethylsiloxane as the main raw material, has excellent aging resistance and mechanical properties, and has good resistance to most building materials Of the bonding performance, in the national economy, especially in the construction of curtain wall has a wide range of applications. With the development of high-rise curtain wall, the function of the Fire Proof Seal is not only limited to excellent bonding performance and aging resistance. Several major fires occurred, so that high-rise building fire safety has become a focus of attention in various fields and research hot topics.

Ordinary silicone Fire Proof Seal as the main raw material 107 base rubber in the 200-300 degrees Celsius can be burned, from a certain point of view are combustible items, and later the major manufacturers have introduced flame retardant Fire Proof Seal to solve the ordinary silicone Fire Proof Seal burning Problem, flame retardant Fire Proof Seal used in the need to suppress the combustion of the building area. Products to meet the GB / T 24267-2009 building flame retardant Fire Proof Seal standard. Qualified flame retardant Fire Proof Seal can be done from the fire self-extinguishing, that is no longer imposed the case of flame Fire Proof Seal to stop burning. Nevertheless, the flame retardant Fire Proof Seal in the continued flame burning will eventually be the same as the ordinary Fire Proof Seal ashes, loss of blocking effect. In the current fire field more and more emphasis on fire conditions to maintain the integrity of the building components in the environment is clearly not meet the requirements. So the flame retardant Fire Proof Seal can not be used as a fire Fire Proof Seal.

Not only has a flame retardant Fire Proof Seal self-extinguishing flame retardant capacity, but also in the high temperature that is not the case of fire ashing, no powder, ceramic occurs. Continue to maintain the Fire Proof Seal sealing effect, effectively maintaining the integrity of building components. Prevent cigarettes It must comply with the national mandatory standards GB 23864 fire blocking material at 1000 degrees Celsius at least 3h to keep the surface temperature of less than 180 degrees Celsius, while the back of the fire surface to be intact, no cracking, do not channeling fire.

The most important function of the fire Fire Proof Seal used in the construction field is to emphasize the ability to maintain the integrity of building components in case of fire. Jintai Chemical's DJ-A3-AT178 fire Fire Proof Seal has the function of ordinary Fire Proof Seal under normal circumstances. It has the function of sealing and sealing the building gap and has certain displacement ability. When the fire occurs, the fireproof Fire Proof Seal Increased temperature of the surrounding colloid gradually hardened and ceramicized, play a role in the closure of the gap, to prevent the flame and smoke from the gap in the further spread.

The fire Fire Proof Seal is in good shape with the ordinary Fire Proof Seal. After the high temperature calcination, the ordinary Fire Proof Seal will be ashed, and the DJ-A3-AT178 will be ceramicized with the effect of adding the ore powder, , Not powder. The ceramic structure formed after the colloid calcination is also affected by the conditions such as bubble density, calcination temperature curve, external pressure and other conditions.

Fire Fire Proof Seal products mandatory certification is the national mandatory product certification in the most stringent a class of products. The process of review is extremely complex, including application acceptance, data review, sample reception, sample inspection, factory review, conformity assessment, certificate collection, post-certification supervision and so on. Only through the above all the audit, the certification body can be issued for the enterprise certificate, which shows the gold content of the certificate.
