Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?

you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.

Q:How much fireclay is needed per cube refractory bricks?

Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.

Q:How many years are the service life of chimney lining refractory brick?

Capacitance magnesite, seawater magnesite, should be the alkaline refractory brick, magnesia-alumina spinel can absorb hydrogen fluoride, generally are magnesia brick, magnesium iron ore, forsterite, dolomite, magnesium dolomite, magnesium silica sand, magnesia-chorme spinel and magnesia chrome sand: Magnesia mineral, magnesium calcium sand, magnesite, magnesium dolomite sand, dolomite, mainly is cordierite

Q:What's the difference between fired clay bricks and sintered porous bricks?

Clay, shale, coal gangue or fly ash as the main raw material, calcined by the hole rate of not less than 25%, the size of the hole is small and large number, mainly used for load-bearing parts of the brick, referred to as porous brick. At present, sintered porous bricks are divided into two types of P bricks and M bricks. As compared with ordinary clay bricks, sintered porous bricks have higher compressive strength, corrosion resistance and durability, as well as light weight and good thermal insulation performance. Sintered porous bricks can be widely used in load-bearing walls of industrial and civil buildings.

Q:What are the main raw materials of refractory brick and runner brick?

Category of refractory , runner brick mainly is clay brick

Q:What material is good of refractory bricks?

It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials

Q:The state's policy on clay bricks

Now the country for the solid clay brick is the policy of emerge of itself and perish of itself. Because solid clay bricks occupy resources, vigorously encouraging new brick, I was open brick reached up to four, but we have to see this with money the disease I do, I don't think they all sold, finally want to engage in a new type of brick, but in the investigation that model free burning brick cost is too high, and a lot of people are not optimistic, finally did not dare to engage in this, we also have the business,

Q:Can refractory bricks be used to pave roads or build a wall?

Refractory bricks are used to build a house, no problem

Q:How about clay bricks?

The strength of brick can be judged by the sound produced by two bricks colliding with each other.Two hands each take a brick, gently hit, such as a uniform, crisp sound, indicating brick high strength, good quality, if the collision sound hoarse or stuffy, it shows that brick strength is low.2. to observe the crack state of bricks, elliptical repeat crack if large surface of the brick on the head, like twistcore, called "spiral brick"; some bricks will be broken, the shell off angle, crack and other symptoms, hand picked up the pieces of a pinch, immediately in powder form. The inner core is yellow and honeycombed. It is called "crisp brick", which belongs to the waste brick.3. to observe the color of brick brick brick section: open, heart was uniform black, no unburned carbon brick, high strength of such. On the contrary, the intensity is low.

Q:how to distinguish the quality of high alumina refractory brick when you buy it ?

see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
