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 building materials can take the place of clay bricks?

Are aging fast, can greatly save the time, from the practical results, the red brick walls every day only skilled workers built about 2.5 cubic meters, while the foam concrete block can be built about 6 cubic meters per day, calculated by 50 yuan per person per day, only a fee per cubic wall can save nearly 16 yuan.

Q:What is the main use of refractory brick?

Almost all high temperature furnace needs of the needs refractory bricks, such as blast furnace for iron smelting, high temperature differential thermal analyzer also use it, refining furnace, converter for steelmaking, muffle furnace, electric furnace and drying equipment. the uses are wide

Q:Should refractory cement hang inner core when use carbon steel pipe make water heating hearth by self?

The main purpose of adding refractory cement or refractory brick is to avoid the sulfur in coal in the combustion process of corroding metal, especially under the conditions of high water content and low temperature of flue gas. If use natural gas after desulfurization, without considering the life circumstances, can not be adopted, but the carbon steel pipe is unsuitable for what you said, safety first! Earnestly!

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:Why can earth make bricks?

Brick is a common masonry material. Brick and tile production and use in China has a long history, "Qin Zhuanhan tile". The raw material for brick making is easy to obtain, the production process is simple, the price is low, the volume of urine is in the combination, and the clay brick also has the advantages of fire protection, heat insulation, sound insulation, moisture absorption, etc..

Q:What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick

Refractory brick tunnel kiln, but if you want fire magnesia-chrome bricks, it may soon be finished, but the energy saving effect is good, using mullite bricks to sinter high alumina brick tunnel kiln burning zone is ok. Of course, if sintering is different, the refractotry bricks require different the kiln shape of tunnel kiln, preheating zone and cooling zone use high alumina brick and clay brick. what kind of products will be sintered in the future, clay brick firing zone had better use alumina hollow ball brick and mullite bricks How high the daily design capacity to achieve, thermal insulation can not be ignored, if firing silica?brick, then I am afraid there are only few finished burning bricks, what 's the purpose of the actual operation of the tunnel kiln you will build Different design of tunnel kiln use different brick, generally sintering high alumina brick and clay brick require good kiln, the cost is also very different, for example, because although the cost is higher, in addition operation is very important for the using effect and service life of the furnace, but the design of kiln type must be reasonable, otherwise it can not reach the expected effect, for example, the highest sintering temperature to achieve

Q:What is the sintering of non clay bricks?

Unfired bricks are bricks used to build walls relative to sintered bricks.

Q:does all the refractory refer to refractory bricks when making steel?

Not only are refractory bricks, and shapeless refractory material; blowing agents, drainage sand, and oxygen are all metallurgical auxiliary materials.

Q:What are the differences between fired brick and clay brick?

Clay brick is a kind of sintered brick, which is made of clay as raw material. Clay brick, ceramic tile and rock sheet brick also belong to sintered brick, so the range of sintered brick is wide.
