Note: When producing silica mortar, differences in ingredients and mixing processes will affect the depth of its color.
Kerui’s silica refractory mortar adopts a finely controlled particle size composition. This makes the refractory mortar easy to spread and level during the construction process. Therefore, this greatly improves the construction efficiency and quality.
Kerui’s silica mortar ensures the high strength and excellent adhesion of the mortar by optimizing the fine particle content. Therefore, the increase in fine particles effectively fills the voids in the mortar and improves the overall compactness.
Like high alumina mortar, Kerui’s silica mortar has low internal porosity and strong anti-penetration ability. Therefore, our products can effectively resist the erosion of moisture and corrosive substances in the environment and extend their service life.
Kerui’s siliceous mortar is also easy to mix and apply and is suitable for various complex construction environments. The optimized particle size composition reduces the construction difficulty and time cost of the mortar during the construction process.
You can use silica mortar as a fire-resistant coating that is resistant to high temperatures and corrosion in the internal coating of some chemical equipment. It can protect the wall of the equipment.
You can also use material refractory mortar for lining and repairing high-temperature furnaces. What’s more, it can withstand high temperature environments and chemical erosion.
Refractory mortar is also used for packaging and fixing electronic components. For example, it is used for insulating filling materials for integrated circuit packaging and sealants for electronic devices.
It can also be used for the maintenance and repair of high-temperature industrial equipment such as glass kiln linings, ceramic kiln linings and aluminum electrolytic cell linings.
When you are looking for refractory castables and mortars for your furnace, the first thing that comes to your mind is where to buy them from. Then, before you place an order, you can choose from a wide range of suppliers.
