The difference between ceramic fiber blanket and aluminum silicate needled blanket

Ceramic fiber blanket also calls silicate aluminum fiber blanket, because one of its main components is alumina, and alumina is the main component of porcelain. Aluminum silicate needling blanket is a kind of heat preservation refractory material made of aluminum silicate long fiber needling by resistance furnace process. Some say they’re the same thing, some say they’re not, they’re two products. Actually blanket of ceramic fiber and needle of silicon acerbity aluminium are in subtle place have distinction. Today, let’s look at the difference between the two.

Ceramic fiber blanket
Ceramic fiber is made by double-sided needling process, which can adapt to high and low temperature environment and work well. According to the different production technology on the market, blanket of ceramic fiber is divided commonly for two kinds, throw silk blanket and gush silk blanket namely.

Features: light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical impact resistance.

Aluminium silicate needle blanket
Aluminum silicate needle felt is a kind of heat preservation refractory material specially made from long fiber of aluminum silicate by using aluminum silicate as raw material and resistance furnace process.

Product features: light weight, high strength, white color, good ductility, regular size, low thermal conductivity, insulation in aerospace, steel, petrochemical, electric power and other high temperature insulation insulation, fire insulation of military equipment can be seen in the shadow of aluminum silicate needle blanket.

Aluminum silicate needled blanket and ceramic fiber blanket common
1. High tensile strength and tear resistance.
2. Excellent chemical stability, corrosion resistance and acid and alkali resistance.
3. Its excellent thermal stability and high porosity.
4. Low heat capacity and thermal conductivity. Heat conduction, heat radiation, heat convection is also helpless.
5. Good attraction and noise reduction performance, noise and external isolation, in the fire insulation at the same time block noise.

Ceramic fiber blanket is made of special aluminum silicate ceramic fiber filament by special double-sided needling process. The interlace degree, delamination resistance, tensile strength and surface smoothness of the fibers were greatly improved by double-sided needling. Fiber blanket does not contain any organic binder, to ensure that it has good process property and stability under high and low temperature conditions.

The above is the difference between ceramic fiber blanket and aluminum silicate needled blanket. The former is mainly divided into ceramic fiber blowing blanket and ceramic fiber swing blanket. Ceramic fiber casting blanket is superior to ceramic fiber blowing blanket in thermal insulation performance because of its long filament and low thermal conductivity. Ceramic fiber silk blanket is mostly used in thermal insulation pipeline construction.
