All along, people’s requirements for fire doors are getting higher and higher, and the standards for fire doors are also stricter. It is an important way to improve the safety performance of fire doors through the research and improvement of fire door core panels, so a series of new fire door filling materials are also applied. The increase in safety requirements and the continuous improvement of chemical processes have changed. Fire door core board from traditional organic core material to inorganic calcium silicate fire door core, vermiculite fire door core, perlite fire door core board, biosoluble refractory fiber fire door core board and other new fire door core materials In the same vein, continue to develop.
The basic functions of fire doors are heat preservation, heat insulation and fire prevention. For the initial wooden fire doors, its scope of use can only be used in environments where the fire rating is required to be below level 3. The filling material in it is Class B fireproof material. For example, the early fire door cores are produced from organic materials such as EPS, XPS, foamed PVC, foamed PE, foamed PUR and other organic materials for thermal insulation. However, due to the flammability of organic materials and the toxic and harmful after combustion gas, hindering the application of such materials. For the slowly developing steel fire door, his filling material must be A fireproof material. Door core filling materials can be divided into vermiculite, mineral wool, aluminum silicate wool, rock wool and other inorganic foams and perlite fireproof boards. Among them, rock wool and aluminum silicate are also harmful to people’s health due to dust pollution. Considering the impact of cost, perlite has a good fireproof effect, but the price has risen higher in recent years, and it does not have an advantage in terms of cost performance. In comparison, the vermiculite-based fireproof door core board, the mineral wool-based fireproof door core board, and the mineral wool magnesite foam fireproof door core board have better cost performance.
With the emergence of new processes and technologies, and people’s changes in safety and environmental protection concepts, some new fire door core materials will be more and more, and the fire performance will be better and better. And high-quality quality control, use advanced technology to create a better life with you. The vermiculite-based fireproof door core panels we produce are natural and environmentally friendly, non-toxic and non-radioactive, fireproof, moisture-proof, corrosion-resistant, economical, convenient for construction, and can be cut into different specifications according to different needs. Reputation, welcomed by the market!
