1,Dsescription of Penetration Resistance Silicon Brick:
1),With aluminium silicate mineral and bauxite as main raw materialsadding a certain amount of additives and binders,the impermeable silica brick can be used as barrier layer of aluminium electrolysis cell.2),The product has the characteristics of high density, high strength, good heat preservation performance and good permeability resistance.3),0.5% admixture and 5% high-quality clay in product ingredients can improve the strength and impermeability of the product.
2,Index of Penetration Resistance Silicon Brick:
Item | Penetration resistance brick | |
SiO2% | ≥70% | |
Fe2O3% | ≤2% | |
Al2O3 | ≤25% | |
Refractoriness | 1600℃ | |
Linear change after reheating | 1280℃,2h | |
+0.1/-0.4 | ||
Apparent porosity | ≤18% | |
Cold crushing strength | ≥35Mpa | |
Unit weight | 3.50 KG/PCS | |
Bulk density | 2.05g/cm³ | |
3,Damage factors in the use of impermeable silica brick:
When the temperature is above 700℃,the volume expansion of refractories is caused by the entry of electrolytes such as Na, NaF and cryolite into the barrier layer from the cracks in the working layer or the pore of the material, which leads to the structural damage of refractories.Na, NaF and cryolite melt will penetrate into the insulation layer further and deposit in the insulation layer, which will reduce the thermal resistance of the insulation layer, resulting in the destruction of the thermal balance of the electrolyzer and can not be used.The function of osmosis is to prevent Na, NaF and cryolite melt from penetrating into the insulation layer further, prevent the insulation layer from being eroded, and make the insulation layer durable, thus protecting the normal use of the electrolyzer.
4,The remarkable features of Penetration Resistance Silicon Brick:
It effectively hinders the anti-penetration effect and protects and prolongs the normal use of the electrolyzer.
5,Main Uses of Penetration Resistance Silicon Brick:
Barrier Layer of Aluminum Electrolysis Cell
6.Good feedback of product use effect,the products have been exported to Kenya, Mexico, Morocco
7.We are a professional supplier, who can provide customers with free product technology, use and other issues.
