3. HIGH-TEMPERATURE CRYSTAL FIBER PRODUCTS
CLASSIFICATION TEMPERATURE: 1600 ℃
PRODUCTS DISCRIPTION:
• Light weight crystal fiber and its product, which can endure high temperature and doesn't contain bond or other components, can be used at 1600 ℃ at most. It can maintain its toughness, strength, pliability and fiber structure when exposed in oxide-ambience, neutral ambience or partial reducer ambience at this temperature longtime. Residue sphere is not included in it and the heat insulation is favored of. It is the result of hi-tech industrialization.
TECHNICAL SPECIALITY:
• 100% mono mullite crystal phase, can be used at maximum temperature 1600 ℃ .
• Low heat-conduction ratio.
• Good thermal shock endurance.
• Good audio-absorbency.
• Maintain pliability under 1600 ℃ .
• Low heat store up.
• High heat reflection character.
• Stabilization of chemical performance, resisting eroding.
• Fiber diameter uniformity.
APPLICATIONS:
• Lining of kiln or furnace.
• Heat-processing kiln.
• Ceramic high-speed firing kiln.
• Door of furnace, enclosing furnace cover.
• High-temperature filter cushion.
• High-temperature seal cushion.
• Heating furnace, equably heating furnace.
Fields of application include the industries of metallurgy, chemistry, machinery, ceramic, electron, etc.
