FAQ

Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.

From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

Q: What are the hazards of solid clay bricks?: According to incomplete statistics, China produces about 70000000 tons of standard coal per year of clay bricks.

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: Characteristics of refractory bricks: The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear?change?on?reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.

Q: What are the disadvantages of sintered clay bricks?: Disadvantages: FrostPan cream also known as cream, is salting out phenomenon in the process of using brick. The excess soluble salt in the brick is affected by water absorption and dissolves when water evaporates. When the crystal is precipitated, it expands and causes the brick surface to flake. Standard: excellent products without efflorescence, first do not allow secondary efflorescence, qualified products is not allowed to have serious flooding.Lime crackingLime burst refers to brick with limestone, turn after absorbing water, because the lime burst and the expansion of the gradually maturing. This phenomenon affects the quality of bricks and reduces the strength of masonry

Q: How aluminium oxide becomes a entity from the the form of powder (such as a ball, a stone, or a refractory brick)?: Just like the process of making steamed bun from flour. Ball milling ---in the auxiliary material to make the slurry --- suppress the body --- high temperature calcination

Q: Would you please tell me how to use the simple method to identify shale brick, clay brick?: Is the shale as raw material for high temperature baked bricks using shale and coal gangue, clay brick not dense surface, general clay brick for load-bearing structure, relatively thick, single shape; shale brick shapes, shapes with holes, in non bearing structure.

Q: Can you direct the clay brick walls embryo: Must not。 Not damp, damp, air tight, poor pressure bearing, bad adhesion between bricks and bricks

Q: How good is the hardness of corundum refractory brick?: The basic materials of corundum refractories are fused corundum or sintered corundum. the refractory brick containing more than 90% of Al2O3 is called corundum refractory brick. so, corundum refractory brick. Corundum has a high hardness (9 level of Mohs hardness) such as zirconium corundum refractory brick. Corundum refractory brick is resistant to acid well and melting point is also high, also known as pure alumina refractory brick products, , it has a good effect. These are closely related with the structure of the Al - 0 key, titanium corundum refractory brick, and other basic slag. It is used in high temperature oxidizing atmosphere or in reducing atmosphere. the metal and glass solution have good stability. a-Al2O3 is the main material of high temperature refractory brick and high temperature electrical insulating material .
