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.

- Inquire about price/MOQ

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:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
Aerated concrete for external walls is to save money. One side is the outer wall.. Solid bricks are the first thing, safety comes first.
Q:How much is a thermal brick
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q:What bricks are thermal insulation bricks?
Insulating bricks, a new type of product that can replace tiles, are mainly used in toilets, kitchens, TV sets, bedrooms, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
Q:Material and making method of light insulating brick
Material production of ordinary light insulating brick clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick.
Q:What are insulation bricks for? Do not use high-rise buildings on the ah?
Heat preservation and heat insulation, that depends on the design of the drawing
Q:What is composite sintering insulation bricks?
Taking the Yangtze River, lake and silt as the main raw materials, the performance indexes of roasting are in line with the technical specifications and technical requirements of the building blocks, referred to as insulating bricks.
Q:What are the insulation materials for heating buried pipelines?
The thickness of insulation layer should be reasonable and economical. If the insulation layer is too thin, the heat loss will be increased; the insulation layer is too thick, and the surface area of the radiator will be increased, and the heat loss will also be increased. In general the design, determine the thickness of the insulation layer according to the factors of insulation material properties, heat medium temperature, often used for 40~50 mm thickness.
Q:What are the specifications of high strength diatomite insulating bricks?
In view of the old and new concrete, steel structure, solid brick wall, hollow brick wall, compressed air brick wall and different brick wall, combined with the company installation patent method, it is suitable for the construction and installation of various types of wall. At the same time, it is also suitable for old house reconstruction. It has excellent outdoor weather resistance, color retention, alkali resistance, water resistance, scrub resistance, crack resistance, temperature resistance, waterproof, wear-resistant, collision resistant, and durable film, adhesion, and excellent anti mildew effect.
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
