- Q:Why in the production of the brick to detect the volume density
- Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.
- Q:Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.
- The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.
- Q:Physical solid waste disposal
- The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing
- Q:The brick is mainly used in the place?
- Partitions used in coking and combustion chambers for coke ovens
- Q:The introduction of silica brick
- The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc.. Rongsheng with refractory
- Q:The introduction of silica brick
- Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.
- Q:The specific content is what gb/t2608-2012 brick
- Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.
- Q:What are the main constituents of refractory bricks?
- Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:
- Q:The hot blast stove when the temperature did not rise against the brick interface decreased
- How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.
- Q:What is acid refractory?
- Refractory materials are mainly quartz glass products, combined with fused quartz products, silica brick and unshaped refractories. Semi siliceous refractory materials are generally attributed to this category. As for fireclay refractories, they are also classified as semi acidic or weakly acidic refractories. Also, zircon refractory and silicon carbide refractory for special acidic refractory materials are also classified into this category.
