Vermiculite fire door core board, as the name suggests, is a door core filled board with vermiculite as the main component. Vermiculite is a mineral with thermal insulation, heat insulation, fire prevention, antibacterial, sound absorption and other properties. The higher use temperature of vermiculite can be Up to 1100 ℃, widely used in thermal insulation materials, fireproof materials. With the expansion of the application of vermiculite panels and the popularization of the demand for fire doors, more and more people choose vermiculite panels as the door core panels for fire doors. The good thermal properties make it stand out among many door core filling materials, and it has the incomparable advantages of many other materials. The unique vermiculite composition of the vermiculite fire door core board is its characteristic.
The vermiculite fire door core board is made of expanded vermiculite as the main raw material, and a certain dose of inorganic binder, through a series of complex processes of hot pressing or cold pressing. Moisture-proof, harmful material-free sheet. In the event of fire and high temperature, it will not produce gas that is harmful to human health, and it is smokeless, non-toxic and odorless, reaching the standard of Class A fireproof board. Vermiculite fire door core board does not contain asbestos, because this material is natural, green, environmentally friendly and fireproof, it has been widely used in Australia, the United States, Europe and other countries in the 1960s and 1970s. Fire door core. The vermiculite fire door core board is used as a fire door, which has many advantages, such as light weight, easy installation and maintenance, etc. Taking a fire door of the same specification and fire rating as an example, the weight of a vermiculite fire door is only its corresponding traditional Half the weight of the product. The light weight of the fire door means that the load of the hinge hinge is low, that is, the damage that may be caused in use is reduced, the service life of the fire door is prolonged, and the maintenance cost is saved. Flame retardant, heat insulation, sound insulation, environmental protection, its indicators are better than other fillers. Using the vermiculite fireproof board as the door core, it can be directly pressed and formed in the factory according to the shape, specification, size and style of the fireproof door, which can improve the fireproof and heat insulation effect of the fireproof door, and also save the installation time and cost, as well as various The stacking space of various materials saves the corresponding cost in terms of labor, process, and site.
