Overview
Jiaobaishi core material is a specialized refractory product derived from high-alumina clay, processed to achieve exceptional thermal and mechanical properties. It is widely recognized in industrial sectors for its ability to withstand extreme temperatures, making it indispensable for high-heat applications. Primarily composed of alumina and silica, this material undergoes rigorous sintering to enhance its durability. Its unique composition ensures minimal thermal expansion, reducing the risk of cracking under thermal cycling. These attributes make it a preferred choice for demanding environments.
Physical and Chemical Properties
Jiaobaishi core material exhibits a density range of 2.5-3.0 g/cm³, contributing to its robust structural integrity. Its melting point exceeds 1750°C, ensuring performance in ultra-high-temperature settings. The material is chemically inert, resisting reactions with most acids and alkalis. Thermal conductivity is notably low, which helps in energy efficiency by reducing heat loss. Its mechanical strength remains stable even under prolonged exposure to high temperatures, a critical feature for industrial furnace linings and kiln components.
Main Applications
The primary use of Jiaobaishi core material is in the construction of kilns and furnaces, where it serves as a lining to contain and reflect heat. It is also employed in the steel and glass industries for ladles, crucibles, and other high-temperature containers. Additionally, this material finds applications in ceramic production and incinerators, where its resistance to thermal shock and abrasion is highly valued. Its versatility extends to petrochemical refining equipment, where stability under fluctuating temperatures is essential.
Safety and Storage
While Jiaobaishi core material is non-toxic, handling its dust requires precautions to avoid respiratory irritation. Workers should use masks and ensure proper ventilation during cutting or grinding operations. Storage should be in dry conditions to prevent moisture absorption, which could compromise its refractory properties. Stacking should avoid excessive weight to prevent cracking. Proper labeling and segregation from reactive materials are also recommended.
B2B Procurement Guide
When procuring Jiaobaishi core material, prioritize suppliers with certifications for refractory product quality. Key specifications to verify include alumina content (45-60%), thermal stability ratings, and dimensional accuracy for pre-formed shapes. Bulk purchases often attract discounts, but ensure storage capacity aligns with delivery schedules. Sample testing for thermal cycling performance is advisable before large-scale procurement. Lead times can vary, so plan orders well in advance for critical projects.
