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: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:How high can aluminum bricks expand at 80O degrees of heat?
When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
Q:How to test the aluminium bricks of high alumina refractory bricks?
Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!
Q:The difference between aluminium refractory and magnesia refractory
Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
Q:What is the standard size of high alumina brick?
The country has laid down a number of criteria for the use of refractory bricks to unify market demand.
Q:Introduction of high alumina brick
High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. 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 identical. For example, European countries limit the content of Al2O3 to high alumina refractories by 42%. In China, the content of Al2O3 in high alumina brick is usually divided into three parts: I, etc. - Al2O3 content, >75%, II, etc. - Al2O3 content is 60 ~ 75%, and the content of Al2O3 is 48 ~ 60%.
Q:What are the high temperature refractory mortars made of?
Siliceous mud, mineral composition and chemical composition is similar with silica, excellent corrosion resistance, water glass slurry, drying shrinkage, but also can be used for bonding fiber products, sealing furnace wall.
Q:How are the grades of high alumina bricks differentiated?
High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%
Q:Use of high alumina refractory bricks?
High alumina refractory brick in Al2O3 more, close to neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so alkaline slag ability than acid resistance slag ability less.It is widely used in building blast furnace, hot blast furnace, furnace top, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..
