Description of Silicon Mortar
Silica mortar is an unshaped refractory material made of silica, soft clay or chemical binding agent and additives in a certain proportion. It is characterized by high bonding strength and good refractory performance. Silica mortar is mainly used for the masonry and repair of hot blast furnace, coke oven and other industrial kilns built with silica bricks.
The physical and chemical properties required for different applications of silica fume mortar are also different. As a manufacturer of silica mortar, we can provide you with customized services, and we have several different uses of silica mortar materials for sale below.
Silica mortar for blast furnace hot blast furnace with SiO2 greater than 94%, 0.2 MPa load softening start temperature of not less than 1600 ℃;
Silica mortar for glass kiln with SiO2 content of 94% to 96%, load softening start temperature of 1600 ~ 1620 ℃;
Coke oven with Silica mortar SiO2 content of 85% to 92%. Load softening temperature for the beginning of 1420 ~ 1500 ℃.
Characteristics of Silica mortar
High heat resistance
Silica refractory mortar has superb heat resistance, which makes it ideal for industrial kiln applications such as furnaces and kilns.
Chemical Stability
Silicon mortar is highly resistant to a wide range of acids, alkalis and corrosive substances. This resistance ensures that the mortar is able to withstand harsh chemical environments without noticeable degradation or loss of performance.
Low shrinkage
Silica refractory mortar has a low shrinkage rate during the curing process. This property helps to minimize the development of cracks and ensures the structural integrity of the refractory lining. By reducing shrinkage, silica fume mortar maintains its dimensional stability and extends its service life and performance.
Strong bond
Silica mortar forms strong bonds with refractory materials such as silica bricks or ceramic fiber insulation. This strong bond ensures the structural stability and service life of the refractory material. Silica fume mortar provides a reliable bond that minimizes the risk of material displacement, cracking or failure at high temperatures.
Easy to apply
Silica mortar is usually supplied as a ready-to-use slurry or powder that can be easily mixed with water to achieve the desired consistency. It can be constructed using standard masonry techniques, allowing easy and efficient installation or repair of refractory linings.
Long service life
Silica refractory mortar has excellent durability and longevity due to its heat resistance, chemical stability and low shrinkage properties. It can withstand repeated thermal cycling and harsh working conditions, ensuring extended service life and reduced maintenance requirements.
Applications for Silica Fume Cement
Furnaces and kilns
Silica refractory mortar is widely used for masonry repair of hot blast furnaces, coke ovens, glass kilns, acid melting furnaces and other industrial kilns built with silica bricks.
Foundry
Silica mortar is used in foundries as a lining material for ladles, crucibles and other metal casting equipment. It resists the corrosive effects of high temperatures and molten metals and ensures the service life and performance of the refractory lining.
Incinerators
Silica refractory mortar is used in the construction and maintenance of incinerators and offers excellent resistance to high temperatures and chemicals. It helps form a reliable and durable lining that can withstand the heat and corrosive conditions of the waste incineration process.
Glass manufacturing
Silica mortar is used for lining glass furnaces, glass storage tanks and other glass manufacturing equipment. The high heat resistance and chemical stability of silica fume allow it to withstand the extreme conditions of glass melting and refining.
Power Plants
Silica refractory mortar can be used in power plant applications including the lining of boilers, flues and exhaust systems. Its ability to withstand the high temperatures and chemical contact generated during the combustion process ensures the efficiency and reliability of the power generation system.
