The production of fumed silica is a high -tech technology, which has high quality and selection requirements for raw materials. The following are the general requirements and selection suggestions of raw materials during the production of fumed silica phase method:

Carbon source: The commonly used carbon sources include natural gas, oil and gas, liquefied petroleum and gas. These carbon sources should be high -purity and do not contain impurities to ensure that silica quality is stable.

Catalyst: The preparation of fumed silica usually requires catalysts, such as magnesium chloride and alumina. To choose a suitable catalyst, it is necessary to consider its impact on the catalytic efficiency, stability and safety of the reaction.

Oxidation agent: The oxidative agents commonly used in the process of gas in the process of gas are oxygen and air. The purity and stability of the oxidant have a great impact on the production process and product quality.

Reaction temperature and pressure control: You need to choose the appropriate reaction temperature and pressure conditions to ensure the reaction and the quality of the product. Under normal circumstances, the reaction temperature and pressure should be controlled within a certain range to avoid the decline in product quality or adverse reactions.

Reacting device material: Because the gas phase silica preparation process needs to withstand the effects of high temperature, high pressure and corrosive gases, the choice of materials for reaction devices is also very important. Common reaction devices include high -temperature and corrosive materials such as stainless steel and titanium alloy.

Gas purification: Gas (such as nitrogen, hydrogen, etc.) used during the preparation process should have high purity to avoid the impact of impurities on product quality.

Reaction condition control: Including gas flow, response time, mixed uniformity, etc., they need to be strictly controlled to ensure that the reaction is fully performed and the quality of the product is stable.

In summary, the requirements and choices of raw material quality in the process of production of gas and white charcoal black are very important. It is necessary to comprehensively consider the purity, stability, response, and the impact of product quality to ensure the production of high quality to ensure the production of high quality. silica product
