In the production process of microsilica powder, impurities can be avoided by the following methods:
First, raw material control
Select high-quality silica ore as raw materials to reduce the initial content of impurities in raw materials. Strict testing and screening of silica ore to ensure that it meets the production requirements.
Avoid the use of reducing agents containing too many impurities, such as coal. Selecting high-purity reducing agents can reduce the introduction of impurities.
Second, production process optimization
Improve the smelting process and precisely control the parameters such as smelting temperature, time and atmosphere. Suitable smelting conditions can reduce the generation and mixing of impurities.
Strengthen the management of the charge to ensure the uniformity and stability of the charge. Avoid mixing impurity substances in the furnace charge.
Adopt advanced dust removal equipment to remove the dust and impurities generated in the production process in time. Ensure the sealing of the collection system of microsilicon powder to prevent the entry of external impurities.
Third, quality testing and monitoring
Ewende establish a strict quality testing system, and conduct regular testing of all aspects of the production process. Timely detection of impurity problems and take appropriate measures to deal with them.
Adopt advanced testing equipment and technology, such as spectral analysis, etc., to accurately detect the content of impurities in microsilica powder. Ensure that the product quality meets the standard requirements.
