Reducing the apparent porosity of fireclay refractory bricks is crucial for enhancing their strength, durability, and overall performance. Here are effective methods to achieve lower porosity:
Optimized Raw Materials: Use high-purity clays and fine-grained materials to minimize voids.
Improved Mixing: Thoroughly mix raw materials for a uniform, dense structure.
High-Pressure Molding: Apply high pressure during shaping to increase density.
Controlled Firing: Optimize firing temperature and duration to ensure complete sintering.
Prolonged Soaking: Extend kiln peak temperature to allow particle fusion and reduce porosity.
At Firebird, our mission is to enhance the quality and performance of ordinary fireclay bricks. We strive to achieve this through:
Careful Material Selection: Using high-purity clays and beneficial additives to improve the properties of our bricks.
Refined Manufacturing Techniques: Applying effective compaction and firing methods to increase density and strength.
Consistent Quality Control: Following reliable quality standards throughout production to ensure our bricks meet industry requirements.
Ongoing Research and Development: Continuously exploring new technologies and refining our products to better serve our customers.
Sustainable Practices: Embracing environmentally responsible practices to reduce waste and energy use while maintaining product quality.
