Conventional Composite Hard Felt - Cylinder
Conventional Composite Hard Felt Features:
- strong anti-radiation ability
- long service life
- energy-saving
- No pollution in a hot cell
- pressure resistance
- resistance to airflow impact
- good insulation,
- Lifespan is 3 times that of soft felt
- Category: conventional composite hard felt
- Thermal conductivity: 0.15-0.25
- Refractory temperature: above 2000 ℃
- Operating temperature in air: ＜ 350 ℃
- The working temperature in a vacuum: <2200 ℃
- Operating temperature in the atmosphere: <3000 ℃
Advantages: strong anti-radiation ability, long service life, energy saving, No pollution in hot cell, pressure resistance, resistance to airflow impact, good thermal insulation effect, Its life span is 3 times that of soft felt.
Application:
- Heat insulation material for high-temperature vacuum furnace
- Used as a reinforcement material to produce carbon/carbon composite materials
3-16mm thick felt made of polyacrylonitrile-based original felt after thermal stabilization and carbonization treatment.
Since 90% of carbon felt is pores, it has excellent thermal insulation performance in vacuum or inert atmosphere,especially under high-temperature conditions
Composite Hard Felt has the characteristics of light weight, small specific heat capacity, soft texture, good thermal insulation, easy operation, etc. It has stable performance and is especially suitable for intermittent operation of high-temperature vacuum furnace, which can save a lot of energy.
