Product Description:

Refractory Brick

CMAX  firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulation

Q:What are the types of building blocks?
1. the use of the different parts, building bricks into bricks, floor brick, brick, brick arch shell, brick brick chimney and sewer.2. different building performance, building bricks into bearing brick, brick, brick, non bearing engineering insulation brick, brick, tile, acoustical tile and other flowers.The use of 3. different materials, is divided into building brick clay brick, shale, coal gangue brick, fly ash brick, slag brick, lime sand brick etc..4. according to the shape, the building brick can be divided into solid brick, microporous brick, porous brick and hollow brick. Ordinary bricks and special-shaped bricks, etc..
Q:What kind of material is clay insulation refractory brick made of?
According to the different origin of general clay brick raw materials are not the same with Henan or Hebei with perlite beads, pyrojewel, use effect and technology of Henan is better than Hebei
Q:What bricks are thermal insulation bricks?
First, replace the aluminum plate, honeycomb board, curtain wall and other common decorative materials, multi-functional integration, a construction can solve the two requirements of thermal insulation decoration, smooth, smooth and beautiful, decorative strong.Two, high strength, good rigidity, light quality, seismic resistance, wind resistance, creep resistance, superior performance, reduce building load, more economical and durable.Three, fire retardant, heat preservation, energy saving, sound insulation, heat insulation, crack resistance, waterproof, according to the 65% building energy conservation requirements for construction design.Four. The installation of the finished product is simple, the process is simplified, the construction period is shortened, and the quality is easy to control.Five, no aluminum, steel, keel support, embedded in the installation, reduce the insulation board and the gap between the wall. Increased safety system.Six, no radiation, green environmental protection, can be widely used in various types of public buildings and family interior decoration.
Q:What is mullite insulation brick?
According to the application temperature can be divided into: 1350 mullite bricks, 1450 mullite bricks, 1550 mullite brick etc..
Q:What's the difference between refractory bricks and insulating bricks?
Insulation brick mainly is used to heat, reduce heat loss, refractory brick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.
Q:Can activated carbon be antiseptic?
Activated carbon is also called activated carbon black. It is black, powder or lump, granular, cellular amorphous carbon, and also arranged crystal carbon.
Q:What is composite sintering insulation bricks?
The brick belongs to the porous brick and has good heat preservation performance. Reached the national 50%~65% energy efficiency standards. High safety (no crack, no seepage), strong durability (with building life), economy (self insulation, no need to increase the cost of insulation).
Q:If there is a main component of cenosphere light insulating brick.
Light heat insulation brick with cenosphere composition, material properties will be more high, especially the main properties of thermal conductivity
Q:What material is good for indoor thermal insulation?
Own home, if the south, hot summer and cold winter zone, with inorganic insulation mortar or polystyrene particles insulation mortar, the effect is very good;
Q:Which kind of balcony heat preservation material is better?
To environmental protection, then use inorganic insulation materials, such as composite silicate, rare earth insulation, this thickness should be more than 5 cm, the construction of auxiliary materials, high cost, to be strengthened
