Expanded perlite is a modern, lightweight, and highly versatile material that has gained popularity in various industries due to its unique properties. It offers a low apparent density, excellent thermal insulation, strong chemical stability, and can withstand a wide range of temperatures. Additionally, it has low moisture absorption, is non-toxic, odorless, fire-resistant, and provides good sound absorption. These features make it an ideal choice for numerous applications, from construction to industrial insulation. One of the most innovative uses of expanded perlite is in the production of **fireproof boards**, which are widely used as core materials for fire doors. This type of board is made by combining expanded perlite with a pre-embedded skeleton and a suitable adhesive as a binder. The result is a high-performance, safe, and durable product that enhances fire protection in buildings. The manufacturing process of expanded perlite fireproof boards involves several key steps: 1. **Material Selection**: High-quality expanded perlite is chosen as the main component, while a suitable skeleton material is selected for structural support. A reliable binder is also carefully picked to ensure compliance with safety and performance standards. 2. **Mixing**: The selected perlite is mixed with the binder using a specialized mixer to ensure even distribution and optimal bonding. 3. **Pressurization**: The mixture is then placed into molds or door cores and subjected to pressure to shape and compact the material. 4. **Curing and Packaging**: After pressing, the product is left to dry naturally, and once fully cured, it is packaged as a finished product ready for shipment. Currently, expanded perlite fireproof boards are available in multiple quality grades, each designed to meet specific application requirements. Whether for residential, commercial, or industrial use, these boards offer a reliable and eco-friendly solution for fire protection and insulation.
