- Q: What is fireproof concrete?
- According to the different properties of fire resisting and heat resisting concrete, they can be divided into silicate, aluminate, phosphate, sulfate, chloride, sol and organic substance, fireproof and heat-resisting concrete, etc.. The following are mainly used silicate, aluminate, phosphate, sulfate fire, heat-resistant concrete.
- Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?
- High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.
- Q: What are the specific raw materials for plastic pallets?
- There are two kinds of raw materials for plastic pallets: one is polypropylene (PP) and the other is polyethylene (HDPE).Plastic pallets for logistics storage: pp+pe material, recycled material 10%;Plastic trays for food trays: food grade PP, PE, pc;Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.
- Q: What is the price of the first grade high alumina brick?
- The specifications and different prices, relatively large fluctuations of the main push of the refractory Dongxin high alumina brick high alumina brick prices generally around 3000 have various levels of Dongxin refractories
- Q: What are the common thermal insulation materials for thermal conductivity?
- The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
- Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?
- The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
- Q: What are the alloy wear resistance materials?
- According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),
- Q: What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Natural element minerals. Of minerals produced by an element (elementary substance). There are about 90 natural elements in the earth's crust, accounting for 0.1% of the total weight of the earth's crust. Can be divided into metal elements, mainly platinum and copper, silver, gold, etc., non-metallic elements, carbon, sulfur, etc., half metallic elements, arsenic, bismuth and so on.
- Q: How to distinguish the good or bad of the high aluminum brick?
- The general high alumina bricks used in the steel, steelmaking, hot blast furnace, electric furnace, blast furnace, reverberatory furnace, rotary kiln lining of industrial furnace in China, mainly composed of a bauxite; sillimanite minerals (including kyanite, andalusite, sillimanite etc.); synthetic material, such as alumina synthesis of mullite, corundum, etc.. High aluminum brick has good quality, high refractoriness, long life and other characteristics, is the main use of refractory brick kiln products, commonly used units can not distinguish the quality and grade of high aluminum brick right in the procurement time, caused by the high prices to buy low grade products, thereby reducing the furnace life therefore, Zhengzhou's Sindh yuan refractory material factory in here is simple to introduce how to identify the quality when purchasing brick high alumina brick.Color: in the purchase of high alumina brick, first of all to see the color, high quality aluminum brick surface smooth, yellow color white, four sides smooth, no broken angle, no cracksWeight: the weight of a block of bricks to be called, according to the standard weight level, high aluminum brick weight of 4.5 kg. Two grade high alumina brick weighs 4.2 kg, three high aluminum brick weighs 3.9 kg, the same level, the same parameters can reach this standard can be regarded as high-quality high aluminum bricks, the opposite is not up to the weight that the quality is good, if there is a crack, four angle uneven, off angle phenomenon, then substandard products, some of the above points to help to the purchaser
- Q: How are the grades of high alumina bricks differentiated?
- If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not exactly the sameFor example, European countries limit the content of Al2O3 for high alumina refractory materials at 42%.
