Manufacturing Details
Cellulose Fiber Overview

Made from high-quality crushed newsprint, this fiber offers a moderate price point with zero environmental pollution. It serves as a superior asbestos substitute, ideal for non-asbestos friction materials, particularly for ceramic fiber and mineral fiber reinforced applications.

  • Main components: Natural Cellulose
  • Characteristics: Easily dispersed, requires no pre-open-processing, provides excellent cold-enhancing effects and high intensity.
  • Application: Significantly improves the intensity of brake linings.
  • Recommended Dosage: Brake drum: 5-20%, Brake disc: 3-10%

Frequently Asked Questions

What is the primary benefit of using Cellulose Fiber in brake pads?
Cellulose fiber acts as a high-quality asbestos substitute that is environmentally friendly and cost-effective. it improves the intensity of brake linings and provides excellent cold-enhancing effects.
What temperatures can the Ceramic Fiber (Alumina Silicate) withstand?
The Ceramic Fiber is designed for high-temperature environments, with a softening point exceeding 1750°C and a working temperature stability up to 1000°C.
What is the recommended dosage for different brake systems?
For Cellulose Fiber, the recommended dosage is 5-20% for brake drums and 3-10% for brake discs. For Ceramic Fiber, use 20-35% for drums and 10-25% for discs.
How should these mineral fibers be stored properly?
They must be stored in a cool, dry location. It is crucial to prevent moisture penetration; therefore, any opened packages should be resealed as quickly as possible.
What safety precautions are necessary during industrial application?
Operators should use explosion-proof equipment and local exhaust ventilation. Personal protective gear, such as safety goggles, is mandatory to prevent irritation and manage risks from static sparks.
What are the key chemical components of the Alumina Silicate Fiber?
The fiber is composed mainly of Silicon Dioxide (SiO2 45%-55%) and Alumina (Al2O3 40-50%), ensuring high chemical stability and heat resistance.
