Classification temperature:
Standard blanket:1260℃ | High purity blanket:1260℃ | Synthetic high purity blanket:1260℃ |
High alumina blanket:1400℃ | Zirconium blanket:1430℃ | Chrome blanket:1500℃ |
Traits:
- Thermal shock resistance
- Low heat storage
- Excellent sound absorption effect
- Excellent heat insulation performance
- Superior thermal stability, excellent resistance to powdering
- Not affected by most chemicals (except Fluoride acid, phosphoric acid and strong base)
- In some application environment, chrome blankets can be used at temperature above its classification temperature(5%contraction at 1500℃).
- Using two-sided needling and thread throwing long fiber to produce tenacious, high resilience and high strength fiber blankets with resistance to tearing before and after heating
Product description:
- ANGKARL ceramic fiber blankets are spread ones with continuous falling cotton, which have higher tensile strength and flat surface after double-sided needling process. There is no organic binder.
- ·It owns excellent resistance to chemical erosion (except hydrofluoric acid, phosphoric acid and strong base, such as Na₂0,K₂O)
- ·Its performance is not affected by oil and water. Its thermal and physical properties can be restored after drying.
- All materials of blankets can be treated to make them waterproof
Typical application:
- Furnace lining, boiler heat insulation, control of heat treatment temperature
- Heat insulation of glass kiln top, furnace door sealing, flue lining
- Heat insulation of pipe, heat insulation components of transport and communication facilities
- Fireproofing and heat sealing gaskets for household appliances
- Thermal stress release and heat insulation in hot weld of outdoor welding
- High temperature filter medium
- Nuclear heat insulation
- Insulation of steam and gas engines
- Thermal resistance elements for automotive industry Site weld
