Q9:Can you offers samples?

A:Of coures,samples are free but freight paid by the buyers.

Q10:What is the service life of your bricks?

A:The service life of different bricks is unlike.It also depends on your using condition and method.

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?: The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.

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: Density of high alumina bricks: High alumina brick by aluminum content is divided into four grades, three grade high alumina bricks content of not less than fifty-five percent, two grade high alumina bricks content of not less than 65, a high aluminum brick content of not less than 75, super high aluminium brick content above 85. As for the high aluminum brick shape, in addition to the standard high alumina brick, high alumina brick and general type, also called special high alumina brick, if the shape is very irregular it is usually called the specific type of high alumina brick, in short, to customized according to the specific use of kiln.

Q: Aluminum content 38, silicon content 55 What refractory bricks?: Semisilica brick: the content of Al2O3 is 15% ~ 30% of aluminium silicate refractory products. Manufacturing products are semi silica quartz containing impurities or native clay kaolin, refractory clay or kaolin beneficiation tailings and the pyrophyllite

Q: Which is better, the soft core or the hard core?: The use of each of the single core copper wire with low line, 1.5 square with cap line home, socket 2.5 square, air conditioning to walk alone line 4 square can, when the terminal box into a socket with leakage protection switch, prevent overload and short circuit.

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: What is spalling resistant high alumina brick?: Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.

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.
