Can solid sodium silicate be used to make fire doors?

    Solid sodium silicate can be used to make fire doors to a certain extent, but it is not the main, sole material for making them.
In the production of fire doors, materials with good fire resistance are usually required to ensure that they can prevent the spread of fire and protect life and property safety when a fire occurs.
Solid sodium silicate has some characteristics that may make it play a certain role in fire doors:
High temperature resistance: Sodium silicate has a certain stability at high temperatures and can withstand a certain degree of high temperature without serious deformation or damage.
Bonding effect: It can be used as a binder to bond other refractory materials together to enhance the overall structural strength of fire doors.
    However, it is not feasible to rely solely on solid sodium silicate to make fire doors:
Limited strength: Although it can play a certain bonding role, the strength of sodium silicate alone may not be enough to meet the structural strength requirements of fire doors.
Incomplete fire resistance: Fire doors need to comprehensively consider the performance of multiple aspects such as heat insulation, smoke isolation, and fire resistance integrity. Solid sodium silicate may have a certain role in some aspects, but it cannot provide comprehensive fire resistance alone.
Generally speaking, fire doors are usually made of the following materials:
Steel: It has high strength and fire resistance and can be used as the frame and door panel material of fire doors.
    Fireproof and heat-insulating materials: Such as rock wool, aluminum silicate fiber, etc., have good heat insulation properties and can prevent heat transfer in fires.
Sealing materials: Ensure that fire doors can effectively prevent smoke and flames from penetrating through the door gap when closed.
In summary, solid sodium silicate cannot be used alone to make fire doors, but it can be used as an auxiliary material in the production process of fire doors and used in combination with other refractory materials to improve the performance of fire doors.
