- Q: What is light brick and what are the characteristics of light brick?
- The design uses the light brick to use the solid clay brick, because the block is big, and the sound insulation effect is good, shape up through the high pressure, reducing the labor intensity! Strength of the products use high quality tabular corundum and practical mullite as aggregate, the use of air conditioning: The use of lightweight brick can increase the usable area, indoor temperature decreases by 2-3 DEG C compared to the use of solid clay brick, reduce the frame section, high alumina high strength bead brick, shorten the construction period, the economical efficiency, with sillimanite as matrix composite lightweight brick generally refers to foam brick, high temperature sintering, will not increase the weight of the floor, low iron mullite, good thermal insulation effect: Can reduce the cost of foundation. The production materials for ordinary light heat insulating refractory brick including clay, diatomite insulation refractory brick. The characteristics of light brick: 1, construction is convenient and simple. 2: The lightweight brick has good workability, saving reinforced concrete can significantly save the comprehensive cost for building, comprehensive cost can be reduced by more than 5%, at the same time, as aerated concrete has thermal insulation, in hot summer, light weight, lower power consumption, high aluminum light insulating refractory brick, improve construction efficiency, normal indoor partition is built by this kind of brick, add special additives and a small amount of rare earth oxides refining.
- Q: What are the weak points of clay bricks?
- In the temperature range of 0~1000 DEG C, the clay brick volume increases with temperature uniform expansion, linear expansion curve approximates a straight line, the line expansion rate is 0.6%~0.7%, about half of the brick. When the temperature reaches 1200 degrees Celsius and then continues to heat up, the volume will begin to shrink from the maximum expansion. The residual shrinkage of clay brick results in the cracking of masonry joints, which is a major drawback of clay bricks. When the temperature is above 1200 degrees, the low melting point of the clay brick gradually melts because the particles are very close to each other due to surface tension, resulting in volume shrinkage.
- Q: The furnace refractory bricks are burnt into ash, what material can resist higher temperature than the refractory brick
- To change a new one, it is a common way now, isn't it?
- Q: What are the differences between sintered bricks and refractory bricks?
- Sintered bricks belong to a type of refractory bricks.
- Q: What is the advantage for ceramic fiber material compared with refractory brick?
- Heat capacity; excellent thermal shock resistance, good chemical stability, bearing sudden cooling and heating, without oven heating and cooling ,high speed, energy saving, is 1/8 of refractory brick, construction is simple. ceramic fiber materials and refractory brick belong to refractory insulation materials; low thermal conductivity: Low bulk density, ceramic fiber material is a new type of lightweight thermal insulation material, is one of the 10 points of lightweight refractory brick,
- Q: Is refractory brick afraid of rain?
- High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
- Q: How about clay bricks?
- The strength of brick can be judged by the sound produced by two bricks colliding with each other.Two hands each take a brick, gently hit, such as a uniform, crisp sound, indicating brick high strength, good quality, if the collision sound hoarse or stuffy, it shows that brick strength is low.2. to observe the crack state of bricks, elliptical repeat crack if large surface of the brick on the head, like twistcore, called "spiral brick"; some bricks will be broken, the shell off angle, crack and other symptoms, hand picked up the pieces of a pinch, immediately in powder form. The inner core is yellow and honeycombed. It is called "crisp brick", which belongs to the waste brick.3. to observe the color of brick brick brick section: open, heart was uniform black, no unburned carbon brick, high strength of such. On the contrary, the intensity is low.
- Q: What is the proportion of lightweight fireclay bricks?
- It is a lightweight refractory product containing aluminium 30%-46%. It is made of clay clinker or light clinker as the main raw material. It is usually produced by combustible material. It can also form porous structure by chemical or foam method.
- Q: What are the differences and uses of non clay bricks, non clay bricks and ordinary red bricks?
- Just bricks without claySuch as foam hollow bricks, straw bricks, and some other cement bonded solid, hollow bricks and so on
- Q: What are the factors that determine the weight of the refractory bricks?
- (5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
