Product Description:

Refractory Brick

CMAX  firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay.

Refractory bricks the main raw material for aluminum silicate fiber cotton, using vacuum

forming production process, operation and add silica sol, aluminum phosphate inorganic binder,

its role is to ensure that the products of the high temperature strength.

Q:The structural specification does not indicate that masonry needs insulation bricks. Is it necessary to use insulation bricks?
Look at the exterior wall insulation design, construction practices and related requirements
Q:What are the new types of building brick materials?
The whole material made of brick and mortar is one of the most widely used building materials. According to whether the masonry is reinforced, it is divided into unreinforced brick masonry and reinforced brick masonry.
Q:What is a JQK composite lightweight thermal insulation brick?
It is a cement based composite waterproof mortar which is pressed and molded. The material has good heat preservation effect and high thermal conductivity.
Q:What is the thermal insulation performance of aerated bricks?
Because of the hollow characteristic, the aerated brick is flexible, and the main body of the building is supported by the reinforced concrete structure, and the brick is only filled. When the earthquake occurs, the reinforced concrete structure will be deformed, and if it is a solid brick, the deformation of the reinforced concrete structure will be broken and collapsed when it is overstock. The use of hollow brick can give the reinforced concrete structure to leave a very good space for expansion.
Q:There are several construction techniques for exterior wall insulation
Exterior wall internal insulation technologyThe interior heat preservation of the wall is to place the heat insulation material on the inside of the outer wall.Advantage:1) waterproof, weather resistance and other technical indicators of finishes and insulation material requirements are not very high, gypsum board, gypsum plaster mortar can meet the use requirement, convenient;2) the internal insulation material is separated by the floor slab and is only constructed within a high storey without scaffolding;3) in the hot summer and cold winter and hot summer and warm winter zone, the inner heat preservation can meet the requirement;4) for the energy transformation of existing buildings, especially at a time when the housing sold to individuals, the whole building (source: China insulation network) or the entire district unified reform is difficult, only by the possibility of a large number of internal insulation. Therefore, in recent years, the exterior wall insulation has also been widely used.Shortcoming:1) because of beam, slab, structural column will cause thermal bridges, more heat loss;2) due to the material, structure, construction and other reasons, the cracking of the facing layer;3) it is not convenient for users to decorate two times and hang ornaments;4) occupy indoor use space;5) the energy saving of the existing buildings is very disturbing to the daily life of the residents.6) wall under outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking.
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
Pulping, pouring system, but if you want to invest in you know more about this knowledge, according to your production decision, cutting system and steam curing system, mainly for operators, grinding, grinding system, production control system uses two typical control methods.
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:Advantages and disadvantages of external formwork and self thermal insulation block
Exterior wall internal insulation technology, wall insulation is to heat insulation materials on the inside of the outer wall.Advantage:1) waterproof, weather resistance and other technical indicators of finishes and insulation material requirements are not very high, gypsum board, gypsum plaster mortar can meet the use requirement, convenient;2) the internal insulation material is separated by the floor slab and is only constructed within a high storey without scaffolding;3) in the hot summer and cold winter and hot summer and warm winter zone, the inner heat preservation can meet the requirement;4) for the existing buildings of energy-saving transformation, especially at present when the house sold to individuals, the whole building or the whole district unified transformation difficulties, only the possibility of internal insulation. Therefore, in recent years, the exterior wall insulation has also been widely used.Shortcoming:1) because of beam, slab, structural column will cause thermal bridges, more heat loss;2) due to the material, structure, construction and other reasons, the cracking of the facing layer;3) it is not convenient for users to decorate two times and hang ornaments;4) occupy indoor use space;5) the energy saving of the existing buildings is very disturbing to the daily life of the residents.6) wall under outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking.
Q:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
All reserved holes larger than 200 * 200 shall be reserved
Q:The insulation layer destroyed after use of cement paste and tiling
The most certain and the method can increase the area of the balcony is to eradicate the insulation layer exposed after cement wall tiles.
