Fiber Needled Insulation Blanket
Fiber needled insulation blanket is a lightweight, flexible refractory material made from alumina-silica ceramic fibers. The difference from ordinary blanket is the needle punching process. That's a mechanical interlocking of the fibers – no chemical binders. The result is strong, resilient, and full of tiny air pockets.
Danyang Dingfeng Industrial Furnace Co., Ltd. is one of the most reliable manufacturers and suppliers of fiber needled insulation blanket in China. If you're going to wholesale durable fiber needled insulation blanket made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Definition
Fiber needled insulation blanket is a lightweight, flexible refractory material made from alumina-silica ceramic fibers. The difference from ordinary blanket is the needle punching process. That's a mechanical interlocking of the fibers – no chemical binders. The result is strong, resilient, and full of tiny air pockets.
We use it in industrial furnaces, kilns, and high temperature piping.
Working Principle
The fiber needled insulation blanket is full of fine fibers arranged so they trap air. Air doesn't conduct heat well. So the blanket cuts down heat transfer by conduction, convection, and radiation.
Put it in a furnace lining, and heat loss drops. Thermal efficiency goes up. The outside of the furnace stays cooler. Neighboring equipment doesn't get cooked.
Features
Insulation. It stops heat from getting out. Saves energy.
Heat resistance. Stays stable in high temperature. Doesn't melt or shrink.
DLight and flexible. Easy to install. Doesn't weigh down the furnace structure.
No binders. The needle punching holds it together. No binders to burn out at high temperature. not waterproof, please do not wash or contact with water;
Thermal shock resistant. You can heat it and cool it without cracks. Doesn't spall like brick.
Strong. The fiber structure holds together. Good tensile strength for a soft blanket.
Cost effective. Less fuel, less power. Pays for itself.
Applications
Industrial furnaces. Annealing, tempering, quenching, carburizing, sintering. Any furnace that needs insulation.
- Heat treatment equipment. Vacuum furnaces, continuous furnaces, trolley furnaces, pit furnaces. The fiber needled insulation blanket goes on the hot face or as backup insulation.
- Metallurgy. Steel reheating furnaces, non-ferrous metal equipment, foundries.
- Petrochemical. Reactor insulation, high temperature pipelines, thermal units.
- Power generation. Boilers, waste heat recovery, turbine insulation.
- Ceramics. Tunnel kilns, shuttle kilns, roller hearth kilns.
