Q:Can you direct the clay brick walls embryo
Times are different, where there is no modern calcination process. With glutinous rice water in the soil, but glue well, but there is no comparable with cement and other building materials. Not long, can not withstand weathering.
Q:How to make the adhesion between refractory brick and the inner wall of the boiler more firm?
Professional furnaceman who can weld pins in the boiler steel plate is needed when have the bricklaying, mortar overflowing, connect with the refractory brick
Q:How many pieces of porous brick is equal to one ton?
Refractory bricks are generally classified into two types, that is, shapeless refractory materials and shaped refractory materials. Shapeless refractory material: Also known as castable refractory, is hybrid power material composed of a variety of aggregate or a kind of aggregate and one or more kinds of the mixture of adhesive particles, it should be used evenly mixed with one or more kinds of the liquid, which has strong liquidity. Shaped refractory material: The general making of firebrick, there are standard rules for the shape, can also temporarily process according to need of building and cutting. The following are the specifications. fireclay bricks 230*114*65 each block 3.0 - 3.6 kg; special-shaped fireclay brick 230*65/55*114 each block 2.8 - 3.3 kg; the reason for the weight's ranges is that because the quality is different, in general, heavy density, good quality!
Q:How much is the silica powder in refractory bricks.
It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.
Q:What is refractory brick? What is refractory clay? ?
Fire clay refers to the light pouring material, raw materials adopt light porous clinker, bauxite, cenosphere, silicon dioxide ultrafine powder and alumina micropowder. Use calcium aluminate cement CA-80 as binder. Refractory brick is burned from stone powder and clay put in 1300 degrees' kiln
Q:Are sintered brick concrete bricks?
Sintered brick: brick made of clay, shale, coal gangue or fly ash, made by molding and roasting at high temperature. Bricks used for masonry, load-bearing and non load bearing walls are collectively called sintered bricks.According to the raw materials, they are divided into sintered clay brick, sintered fly ash brick, sintered coal brick and so on.A sintered brick with a solid or void ratio of less than 25% is called a sintered ordinary brick.The production and use of ordinary clay brick has been in China for more than 3000 years. Nowadays, ordinary clay bricks still dominate the wall materials used in construction projects. Although the ordinary clay brick has many disadvantages, due to its low cost, simple process, design and construction technology is mature and people's inertia and other reasons, the ordinary clay brick for quite a long period of time, especially in rural areas, is still one of the main wall materials.
Q:Why is the house made of refractory bricks not warm in winter
Heating equipment can be used
Q:what is application of high alumina refractory brick?
reverberatory furnace 1, close to the neutral refractory, but because mullite crystallization has not formed the network organization, so the load softening temperature is not higher than silica brick. the refractoriness of high alumina brick is higher than fireclay brick and semi-silica brick, mainly used in blast furnace, nozzle brick,etc. it is up to 1790 C~ 1750, can resistance to acid slag and alkaline slag erosion. hot blast furnace, blast furnace, high alumina brick are widely used for producing open-hearth furnace regenerative bricks, because it contains SiO2, low impurity content, which belongs to high-grade refractory materials, electric furnace. 2, plug head used in pouring system . In addition. 3, because high aluminum products contains more Al2O3, forming less fusible vitreous body, so the high load softening temperature is higher than clay brick. because rotary kiln lining, slag resistance of high alumina refractory brick contain more Al2O3, so the ability of anti alkaline slag is weaker than anti acid slag. so it has a wide range of application. high alumina refractory brick due to the following performances
Q:What are the differences between sintered bricks and refractory bricks?
Easily weathered. There is no obvious difference in the usage between fired pavingbricks and refractory bricks; sintered bricks are generally used for residential road and landscape engineering, they do not fade; refractory bricks are used for all kinds of kiln constructions in plant: It is not anti-freeze (when the temperature is below the zero degree, the brick will easily "blister" in the saturated state), the reasons are high compressive strength and high temperature zone' heat insulation and so on. Fired pavingbrick is a powerful vacuum extrusion type. Fire suppression road brick is high temperature furnace brick, which is not suitable to be used as road brick. Its characteristics are: Wear resistance and freeze-thaw resistance (the anti freeze-thaw cycle of brick is more than 50 times in saturated state), non weathering, sidewalks, short service life. Sintered brick belongs to the building material, refractory brick belongs to the industrial kiln material, which is easy to moss
