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

Q5: Can you give me a brief introduction of the application of your products?

A5: CNBM (China National Building Material) core refractory business comprises the production, sale and installation of high-grade refractory products, the development and implementation of customized system solutions as well as rendering outstanding services for the key industries in Glass, Iron& Steel, Petrochemical, Cement, Ceramic and Nonferrous Metals.

Q:Can the PE sintering plate dust collector be suitable for dust removal in the coking plant?
The sinter plate dust collector is also called plastic plate dust collector. The utility model has the advantages that the utility model can adapt to various complicated working conditions, the dust removal rate is 99.99%, the utility model has the advantages of long service life, stable operation, high temperature resistance, and the utility model is a leading dedusting equipment in china.
Q:What is the main component of corundum?
Corundum is mainly used in advanced grinding materials, watches and precision mechanical bearing materials. A ruby based artificial crystal used as a laser emitting material. Ruby and sapphire are corundum minerals. Except for the starlight effect, only translucent transparent and vivid corundum can be used as gems. The red is called ruby, while the other tones of corundum are commercially referred to as sapphires.
Q:Is liquid phosphoric acid two aluminum hydrogen flammable?
Liquid phosphoric acid two hydrogen aluminum features: easy mixing, molding, especially suitable for field construction, so liquid phosphoric acid two hydrogen aluminum is not flammable
Q:How to improve the induction furnace campaign, from the promotion of refractory life start
According to the workpiece, choose the appropriate hardware castable, corundum brick or refractory bricks, etc.
Q:What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
Fused zirconia corundum refractory material of glass fiber kiln quantity is little, generally used in the kiln feed arch furnace flue, where large amount of places are currently using dense zirconium Zr, dense chromium
Q:What's the jade stove for?
Is it a furnace made of corundum or a furnace for smelting corundum?Corundum brick stove is commonly used as a refractory material sintering furnace, can be fired refractoriness in refractories, below 1700 degrees such as brick, corundum brick, brick, alumina hollow ball and so on
Q:What are the refractory materials?
Neutral refractory is mainly composed of alumina, chromium oxide or carbon. Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry.
Q:Wave tile and throwing glaze, tile which good?
The main advantages of all glazed glazed tiles are that they can be very rich and beautiful in texture and pattern, and they are suitable for family decoration, and can choose patterns according to their own family decoration style. Compared to the glazed tile, it has better pollutant discharge performance, and many pollutants are difficult to penetrate into it.
Q:What can zirconium sponge do for those industries?
Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.
Q:What equipment is used for producing diamond blanks? How much is the investment?
Plus all the cables fifty thousand. Steel 10000 yuan. Corundum bricks; insulating bricks; clay bricks, these three require more than ten thousand. The electrode is about one hundred thousand. It's just an investment in an electric furnace. Together with the rear section processing and raw materials need hundreds of thousands of.
