(b) Low heat capacity

(c)Good stability

(d) High strength

(e)Low size tolerance


Description

The description of New Micro-nano Insulating Brick Series:

The new micro-nano insulating brick series products solve the needs of thermal insulation of

the wall and bottom of various large furnaces, and the working temperature can be from 600°C to 1400°C. 

With a wide range of application, good thermal insulation performance and high strength,

the product can meet the requirements of energy saving and environmental protection of various furnaces.


(1) Main advantages and features

(a) Low thermal conductivity:With low thermal conductivity, it has good heat insulation effect and can make the furnace wall thickness thinner 

under the same temperature condition, thus saving more cost.

(b) Low heat capacity:Due to its ultra-light bulk density and low thermal conductivity, the insulating brick accumulates less heat inside, making it more energy efficient.

(c)Good stability:With very low iron oxide and alkali metal content, its stability is better within the specified service temperature.

(d) High strength: Its strength at normal and high temperatures is higher than other products with the same bulk density at the same temperature.

(e)Low size tolerance:The size tolerance is within 0.05mm, the dimensions can be customized according to customer requirements.


(2)Typical Applications

It can be used as a thermal insulation backing layer of refractory materials, and the application include: all kinds of industrial furnaces, 

hot blast furnaces, heating furnaces, smelting furnaces, flue pipes, hot air ducts and other heating and heat generating parts.

(a) Roller kilns Tunnel kiln

Application: Furnace walls and bottom insulation layer of the ceramic roller kiln.

Alternative of following: Lightweight clay brick, high alumina insulating brick, mullite insulating

brick.

Advantages: not easy to shrink, not easy to pulverize, performance not easy to decay, more

cost-effective.

(b)Large Hot Air Duct

Application position: Insulation layer of large hot air duct.

Alternative of following: Lightweight clay bricks, high alumina poly-light bricks

Advantages: lower outside wall temperature, more energy efficient, lighter weight of thermal

equipment more cost effective.
