One, what is the fire and theft-proof door filling material?
Currently, many anti-theft door fillings are made of honeycomb paper. The quality of an anti-theft door is not directly related to the filling material; the filling material mainly serves to provide cushioning and sound insulation. Therefore, it is more important to ensure that the steel plates of the anti-theft door meet the required standards rather than focusing on the specific filling material.
《General Technical Conditions for Anti-Theft Security Doors》GB17565 does not specify the filling material for anti-theft security doors. Currently, widely used filling materials for anti-theft security doors include mineral wool, honeycomb paper, expanded polystyrene, and aluminum honeycomb. If only the anti-theft security function is considered, using honeycomb paper as the filling material should be acceptable. However, when both anti-theft security and fire protection are required, using honeycomb paper as the filling material within the door cannot meet the fire protection requirements. It is recommended to use mineral wool as the inner filling material for anti-theft security doors to provide insulation, fire protection, and thermal insulation.
Mineral Wool Materials: Mineral wool originates from Hawaii. Mineral wool products utilize high-quality materials such as basalt and limestone as primary raw materials. After melting at temperatures of 1450°C or higher, the materials are rapidly spun into fibers using advanced four-axis centrifuges. A specific amount of adhesive, dust-proof oil, and water-repellent agent is then added, followed by collection using a cotton machine, a swing hammer method, and three-dimensional laying, and finally, the mineral wool products are solidified, cut, and formed into various specifications and applications.
Two. What are the differences between fire doors and burglar-proof doors?
1、Different functions
In a literal sense, fire-resistant doors are designed to withstand fire, so their primary function is fire protection, resulting in high fire resistance. Anti-theft doors, also known as "anti-theft safety doors," are designed to prevent theft and unauthorized entry. They not only prevent intruders from entering but also ensure safety.
2、Different materials
The materials used for anti-theft doors are primarily steel. Anti-theft doors are designed to resist tools such as chisels, screwdrivers, and crowbars for at least 15 minutes. In contrast, fire-resistant doors utilize fire-resistant materials that must be highly resistant to fire and high temperatures, and should not release toxic gases, while preventing the entry of toxic gases.
3. Different safety characteristics
Compared to fire doors, burglar-proof doors exhibit significantly higher hardness and sealing properties, and are less susceptible to being pried open. Conversely, fire doors are more easily compromised. Therefore, burglar-proof doors offer a much higher level of security.
4、Different standards
Anti-theft doors must have the "FAM" marking and comply with the general technical conditions for anti-theft security doors specified in GB17565-2007. Fire doors generally do not have specific standards.
