The main purpose of thermal insulation is to reduce heat loss, save fuel and ensure temperature during the working process. Ceramic fiber module is a new type of lightweight thermal insulation material which has been developed in recent years. It has many advantages.

Thermal conductivity is a parameter of the heat transfer capacity of the thermal insulation material. The thermal conductivity of the insulation product should be as low as possible. Ceramic fibre has very low thermal conductivity. When the module is used at the temperature of 600 degrees C, its thermal conductivity is only 0.16w /(M.K). So its thermal insulation property is very good.    

Ceramic fiber module has low density and is light in weight. The low density enables ceramic fiber module to have good thermal insulation effect. In order to save energy and reduce the load of thermal insulation furnace during the working process, lightweight thermal insulation materials should be used as far as possible. The density of the ceramic fiber blanket is only 96kg/m3 and 128kg/m3. After the blankets have been made into ceramic fiber module, the weight of the finished fiber module is between 210-220kg/m3.  

Ceramic fiber module has high using temperature. The long time working temperature of the module is between 1000-1350 degrees C. This is the relatively high temperature among the thermal insulation materials, except for the temperature of the mullite fiber, which can withstand high temperature of 1600-1700 degrees C. 

It has high compressive strength. Ceramic fiber module is a soft loose state thermal insulation material. Generally, it can receive the load of pressure without damaging.

Ceramic fiber module has a small expansion coefficient. If the expansion coefficient of the insulation material is large, it will cause the deformation or even damage the furnace due to the greater stress after heating. Unlike the conventional insulation materials, ceramic fiber modules do not expand when heated, but have a heat shrinkage rate of < 3%. The modules can squeeze each other tightly when the strapping tapes are released after installation. So it does not need to reserve expansion joints when used.

Ceramic fiber module has excellent chemical stability. It can resist most of acid and alkali and is not easy to oxidation. This can protect the furnace shell from corrosion and extend its service life.   

In order to reduce the heat loss of the insulation furnace, the thickness of the thermal insulation layer should be calculated economically. Ceramic fiber modules can be flexibly customized in sizes according to the use environment. 

Compared to other thermal insulation materials, ceramic fiber modules have excellent thermal insulation effect.
