Product Description:

1. Characteristic

High strength

Low thermal expansion coefficient

Good thermal conductivity and thermal shock resistance

Good resistance to liquid aluminum erosion capability

High erosion

2. Applications

Widely used in large aluminum electrolytic cell of lining material. In the electrolytic aluminium industry, because of nitride bonded silicon carbide products can be made thin wall lining, enlarge the tank capacity, improve the thermal conductivity, can rapid cooling, and they are permitted to enter a higher power, increase the tank production capacity, at the same time, in its surface can form alumina and cryolite of eutectic content, in order to protect the tank lining work layer, prolong service life, therefore, this product is aluminum industry generally welcome.

Q:What are the types of building blocks?
1. the use of the different parts, building bricks into bricks, floor brick, brick, brick arch shell, brick brick chimney and sewer.2. different building performance, building bricks into bearing brick, brick, brick, non bearing engineering insulation brick, brick, tile, acoustical tile and other flowers.The use of 3. different materials, is divided into building brick clay brick, shale, coal gangue brick, fly ash brick, slag brick, lime sand brick etc..4. according to the shape, the building brick can be divided into solid brick, microporous brick, porous brick and hollow brick. Ordinary bricks and special-shaped bricks, etc..
Q:Can fly ash brick keep warm?
Sure, I do fire-resistant insulation bricks, we also use fly ash ah!
Q:What kind of material is clay insulation refractory brick made of?
Alumina silicate refractories with a content of 30% ~ 46% are called clayey refractories. Clay products are mainly made of mullite, glass phase, square quartz and quartz.
Q:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
All reserved holes larger than 200 * 200 shall be reserved
Q:The insulation layer destroyed after use of cement paste and tiling
The most certain and the method can increase the area of the balcony is to eradicate the insulation layer exposed after cement wall tiles.
Q:What are the new types of building brick materials?
Sintered silt insulation brick, steam block, light building block, hollow clay brick, etc..
Q:What bricks are thermal insulation bricks?
Thermal insulation brick is a new type of building material synthesized with macromolecule material. Grey, hollowed out bricks are basically.
Q:Material and making method of light insulating brick
The strength products are made of high quality tabular corundum and mullite as aggregate, silicon carbide as matrix, additional special additive and a small amount of rare earth oxide to be mixed, and then formed by high pressure molding and high temperature sintering.
Q:What is the bulk density of the sintered bricks?
Sludge brick density is about 1000Kg/m or so fand.
Q:What is the thermal insulation performance of aerated bricks?
Aerated brick light weight, heat preservation, heat insulation, sound insulation, easy processing, using a variety of hybrid material production, rich production of raw materials, especially the use of fly ash, and comprehensive utilization of industrial waste, environmental pollution, saving farmland, have a good social and economic benefits, is an alternative to the traditional solid clay brick ideal wall materials. Gongyi Machinery Factory is specialized in producing aerated brick equipment manufacturers.
