Q:Why should the clay bricks be watered first when they are building masonry walls?

Sintered clay brick because there are a lot of capillary, in the dry state water absorption ability is very strong, if you don't use water, water in the mortar will soon be sucked out of the brick, mortar workability is reduced, operation is difficult to spread the real tile.

Q:How to repair the boiler?

What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick

Q:Are refractory bricks poisonous?

Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive

Q:What are the main components of refractory bricks

The main ingredient of silica brick is monox. there are various materials of refractory bricks, the main component of high alumina brick and clay brick is aluminium, the main ingredient of each kind of material is not the same, the main component of magnesia bricks and magnesia chrome bricks is magnesium oxide

Q:How to classify light refractory bricks?

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:What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?

use castable refractory

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:How to built refractory bricks as fitting between square and circle ducts

Use rectangle at the bottom and knife type for the top. trapezoid for junction.
