Vacuum formed insulation is a type of thermal insulation composed of aluminosilicate ceramic fibers reinforced with polymer resins. These insulators are manufactured and supplied in two main categories: 1260°C (2300°F) and 1430°C (2606°F) rated options.
Key Features of Vacuum Formed Insulation
- High-Temperature Stability: It can withstand continuous operation at high temperatures up to 1430°C (2606°F).
- Thermal Shock Resistance: These insulators are resistant to sudden temperature fluctuations, preventing cracking or breakage.
- Low Heat Storage: It exhibits low heat storage, minimizing heat loss.
- Lightweight: These insulators are lightweight, facilitating easy transportation and installation.
- Good Chemical Resistance: It is resistant to corrosive chemicals.
Installation of Vacuum Formed Insulation
It is typically installed using steel anchors or specialized insulation mastic around furnace inspection doors. These insulators can withstand thermal shock caused by temperature drops associated with opening and closing furnace inspection doors.
Significant Applications of Vacuum Formed Insulation
- Inspection Door Insulation: It can be used to insulate furnace inspection doors, preventing heat loss.
- Furnace Door Perimeter Insulation: These insulators can be employed to seal around furnace doors, preventing cold air from entering the furnace and heat from escaping.
- Expansion Joint Insulation at Sponge Iron Furnace Peephole Installation: It can be used to insulate and seal expansion joints at sponge iron furnace peephole installation points.
- Radiant Tube Segment Insulation in Boilers and Furnaces: These insulators can be utilized to insulate radiant tube segments in boilers and furnaces, minimizing heat loss.
- Ideal Asbestos-Free Alternative: Vacuum formed insulation serves as an ideal replacement for asbestos and its products, posing no health hazards.
