- Q:Why should the clay bricks be watered first when they are building masonry walls?
- And because a portion of the water in the mortar brick absorb, can lead to early dehydration, but are not very good on the hydration of the brick and mortar bond strength weakened, greatly reduce mortar and masonry compressive strength, shear strength, affecting the integrity and seismic performance of masonry.
- Q:What are the simple ways to distinguish between excessive clay bricks and less fired clay bricks?
- Generally speaking, compared with the exterior burning brick, the internal combustion brick not only saves the clay and the waste material, but also has smaller volume density, lower thermal conductivity, and can increase the intensity by about 20%. Burnover light color, sound, low intensity; burned brick deep color, crisp sound, high strength, irregular size. These two kinds of bricks are unqualified products.
- Q:What is common brick, firebrick and hollow brick?
- Mainly used for smelting furnace and silica brick. There won't be problem by using scientific methods. Refractory brick----is refractory material with a certain shape and size. According to the preparation process, can be divided into firing brick. Similarly. Hollow bricks are very scientific in use. The hollow brick is just a kind of building material, belonging to the layman practices, hollow clay brick, unburned brick, shale hollow brick, electric melting brick (casting brick). High temperature building materials and structural materials used as building kilns and various thermal equipments, and refractory heat insulating bricks. Professional saying within the construction industry is that the argument of prohibiting the use of ordinary brickis is not scientific; according to the shape and size, can be classified into standard brick, construction, whether there is problem or not on cement and other related ingredients is related when it is under construction, the ability of 1, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action, how to design. For example, refractory clay brick, strictly implement national standards to use qualified hollow brick. 8 earthquake, high alumina brick , magnesia brick, etc. due to the security risks. Hollow brick is classified into cement hollow brick, the house that built by cement hollow brick collapsed leading to many deaths, investigate that the foundation is suitable for the use of hollow brick or not, 580 degrees - 1. Will mislead the public, the high temperature of 770 degrees Celsius, must be corrected. There will be no problem if use scientifically according to strict procedures. There will be problem if the use of the solid brick is not strictly implement the state relevant standards. Also called refractory brick, special-shaped brick and etc. Refractory material made from refractory clay or other refractory raw materials
- Q:does Kyrgyzstan have the refractory brick to build tunnel kiln, whose specifications are 390,235,11, 240,120,60.
- Domestic standard brick has no brick in this specification. only can be customised. Otherwise only have 230 * 65 * 114.
- Q:th choose of different refractory bricks in the rotary?kiln
- According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
- Q:What is the heating temperature in the test method of thermal shock resistance of refractory bricks
- 1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.
- Q:what is consequence of high load and soft low of high alumina refractory brick ?
- softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
- Q:How about clay bricks?
- Fired ordinary brick is one of the indispensable building materials in production and life, but its quality is not good or bad in the absence of professional equipment. Now to introduce a little trick:According to the main raw materials for clay brick, shale, coal gangue and fly ash brick. Mainly in our local clay brick. According to the compressive strength of weathering resistance of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst into superior products, first-class products, qualified three quality grades.
- Q:When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
- unnecessary
- Q:What is the proportion of lightweight fireclay bricks?
- The ingredients are mixed with water to form plastic mud or mud, by extrusion molding or casting molding, after drying at 1250-1350 Deg. C oxidation atmosphere sintering. The volume density of commonly used clay bricks is between 0.75-1.2g/cm3. In reality, the proportion is 1.
