Vermiculite board is manufactured by hot or cold pressing expanded vermiculite with a specific amount of binder, resulting in high strength and toughness. This board also features thermal insulation, heat resistance, fireproofing, and asbestos-free properties. When heated to 1200°C, it does not emit gases harmful to human health and achieves Class A fire rating. This product can be used in fire door cores, fireplace linings, and wall materials. Vermicul
Thermal conductivity of vermiculite boards. The thermal conductivity of vermiculite boards ranges from 0.047 to 0.081 W/(m·K). When discussing the thermal conductivity of vermiculite boards, some may not understand what thermal conductivity means. Let's first clarify: thermal conductivity is the rate at which heat flows through a material per unit area, per second, per degree Celsius temperature difference across its surfaces, under steady-state heat transfer
With the growing popularity of vermiculite board applications, an increasing number of people are choosing vermiculite board as the core material for fire doors. Today, vermiculite boards for fire door cores have gained widespread adoption. Using vermiculite board as the core material for fire doors undoubtedly offers unique advantages that other materials cannot match. What are the benefits of using vermiculite board as a fire door core? Let's explore them be
What issues should be addressed in vermiculite board production? Various problems may arise during the manufacturing process, typically stemming from raw material selection and mixing. Vermiculite board production can be both simple and complex. For seasoned manufacturers, these challenges pose no significant issues. However, for newly established manufacturers with limited experience, these issues may disrupt production schedules and affect delivery timelines. Therefore, whether you are an esta
