85 Type Alumina PCW Fiber
The Type 85 alumina fiber is derived from a combination of Type 72 fiber and Type 95 fiber. It is primarily tailored to meet the specific requirements of customers and offers excellent flexibility and exceptional temperature stability. This versatile fiber serves as a valuable raw material for various downstream products and serves as an effective reinforcement material in composite applications.
Product Introduction
The 85-type alumina fiber is created by combining the 72-type fiber with the 95-type fiber. It is manufactured using the internationally renowned “sol gel” method, with its main components consisting of 85% Al₂O₃ and 15% SiO₂. This fiber demonstrates outstanding performance characteristics, reaching the highest standards in the international market. It possesses remarkable flexibility, exceptional fire resistance, and excellent thermal insulation capabilities.e.
Product Performance
Excellent High and Low Temperature Resistance
Al2O3 Fibre can withstand service temperatures ranging from 1400℃ to 1800℃. Remarkably, even after being exposed to liquid nitrogen (-196℃) for 24 hours, the fiber’s strength remained unaffected.
Acid and Alkali Resistance
After immersing in a 10% alkali solution for 24 hours, the fiber strength retention rates are as follows: NaOH—40%, KOH—65%, and NH4OH—95%. Similarly, the fiber strength retention rates after soaking in a 10% acid solution for 24 hours are as follows: HCl—96%, H2SO4—95%, HNO3—96%, and H3PO4—95%.
Slag Free Ball
Our fiber is free from shot particles(≥45 μm). This absence of shot particles has contributed to an improvement in fiber strength. Additionally, the thermal insulation and fire resistance of the fiber are inversely proportional to the shot content. In other words, the lower the shot content, the higher the thermal insulation and fire resistance properties of the fiber.
Excellent Electrical Insulation
The electrical resistance of alumina fiber shows a decline as the temperature rises. Once the temperature surpasses 600℃, the resistance tends to remain relatively stable. Moreover, the dielectric constant and dielectric loss of alumina fiber exhibit consistent values at high temperatures, making it a suitable material for high-temperature wave transmission applications.
Excellent Flexibility
The fiber demonstrates remarkable flexibility, making it highly resistant to breakage during the acupuncture process. It is an exceptionally well-suited product for acupuncture procedures.
Strong Design
Through the adjustment of chemical composition and heat treatment processes, it is possible to obtain products with diverse properties that can cater to various application requirements.
