Product Description:

Refractory Brick

Refractory brick can be divided into three process: Raw material, molding, burning.Generally, refractory brick was molded by dry pressing. By means of mixing the material uniformity in proportion and aging mixture some time. Then, pour some powders into the module and dry pressing. After dry pressing, the adobe need to pushed in the drying kiln  to stoving or stay in the air  to drying. This progress will need about 3-5 days.  After this progress, then push the adobe into the tunnel furnace or shuttle  kiln to burning  around 1300C. This progress will be need about 5-7 days.

After burning,  the brick will be packed in pallet and leave the factory.

Q:Several kinds of energy-saving bricks
It can be said that the type of brick is the kind of energy-saving brick. Coal gangue sintered brick (known as red brick), porous brick, hollow brick, aerated concrete block brick, etc..
Q:What is the price of fireproof insulation material?
Fire insulation materials are various, different specifications, grades of prices are different, according to market rules, there will be fluctuation, the most commonly used are insulation rock wool, insulation board, insulation bricks, fire blocking materials.
Q:How to reinforce a porous brick foundation?
Pressure grouting method is changed from independent foundation to strip foundation, from strip foundation to raft foundation and pile foundation, from brick strip foundation to concrete strip foundation.
Q:Is the quality of brick made of small-sized self insulation block equipment the same as that of large block brick equipment?
In fact, brick and tile production is only a different production, the quality of brick produced is the same, from the silver horse experience
Q:What are the improvements and improvements during the trial production of insulating bricks?
Per square metre weighs only about 1.4 kilograms, reduce the burden of building.Simple production: completely break through the traditional process, greatly shorten the construction cycle.
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
Specific funding, different production, different raw materials configuration will be different. According to the design requirements, refining production process, for production process, production management level, complete monitoring, pulping system on the lower computer, based on control level; lower machine by the programmable controller (PLC) is mainly composed of a crushing system. The host computer takes the standard industrial control computer (IPC) as the main man-machine interface (HMI) and beating system, and if possible, it is recommended to investigate on site
Q:Advantages and disadvantages of external formwork and self thermal insulation block
Exterior wall insulation form, single material thermal insulation exterior wall: aerated concrete, sintered insulation brick compound thermal insulation exterior wall:According to the different settings of thermal insulation materials, it can be divided into internal insulation, external insulation and sandwich insulation exterior wall. Thermal insulation decorative integrated board: Other: thermal insulation block, etc..
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:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
Compared with ordinary bricks, porous brick has the following masonry points: 1. All bricks must be watered before they are built, and no bricks are allowed to be applied to the wall.
Q:Are there any differences between insulating bricks and refractory bricks
Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
