What are the chemical composition, proportions and batching methods of refractory mortar?
Refractory mortar a special material made of a variety of raw materials. Its chemical composition, proportion and batching method have an important impact on its performance and use effects.
Chemical components:
Refractory mortar mainly composed of oxides such as alumina, silicon oxide, and calcium oxide. Among them, alumina is the main component, its content is usually more than 30%, and it plays an important role in improving refractoriness. In addition, silicon oxide is also one of the important components, its content is usually more than 10%, which can improve the strength and stability of the material.
Ratio:
The proportion of refractory mortars according to its use requirements and performance requirements. Generally speaking, the higher the alumina and silica content, the higher the refractoriness and strength. At the same time, in order to improve the fluidity and plasticity of the material, some binders and solvents are usually added.
Ingredients:
The mixing method of refractory mortar generally includes the following steps:
1. Determine the content and proportion of each raw material according to the usage requirements and performance requirements.
2. Mix the raw materials together according to the proportion, add appropriate amount of water and stir.
3. During the mixing process, additives such as binders and solvents can be gradually added to improve the fluidity and plasticity of the material.
4. After stirring evenly, let it sit for a while to allow the raw materials to fully react and combine.
5. Put the mixed refractory mortar into a bag or storage tank for use.
In short, the chemical composition, proportion and batching method of refractory mortar have an important impact on its performance and use effects. During production and use, it is necessary to strictly follow the requirements to ensure product quality and performance.
