- Q: How much is one ton of high alumina refractory brick?
- High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.
- Q: What are the specific raw materials for plastic pallets?
- With excellent mechanical properties, its strength and elasticity are higher than HDPE, and it has good flexural fatigue resistance. It has good heat resistance and good chemical stability. Besides being concentrated by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. The high frequency insulation performance of polypropylene is excellent because of its almost no water absorption, so the insulation performance is not affected by temperature.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
- Q: What are the common thermal insulation materials for thermal conductivity?
- Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
- Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?
- High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick
- Q: How to make refractory bricks and boiler wall adhesion more firm?
- If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.
- Q: What is the apparent porosity of high alumina brick?
- In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
- Q: The difference between clay bricks and clay bricks
- Clay brick is a small building with artificial bulk. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. It is a building material that is loved by the people.
- Q: What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
