Sintered sand refers to a sand like material formed by sintering specific materials (such as quartz sand, quartz powder, pigments, etc.) at high temperatures, which has high strength, high hardness, and high wear resistance. The production process and usage precautions of sintered sand are important links to ensure its quality and application effectiveness. The following is a detailed explanation of these two aspects.
1、 Production Process of Sintered Sand
Raw material preparation:
The main raw materials for sintered sand include kaolin, mullite, talc, etc., and sometimes industrial waste such as tailings are also used as raw materials.
The raw materials need to undergo pre-treatment such as grinding and screening to ensure uniform particle size and no impurities.
Mixing and Forming:
Mix the pre processed raw materials evenly in a certain proportion.
Using methods such as extrusion, compression, or injection molding to shape the mixed raw materials into the desired shape and size.
dry:
The sintered sand after molding needs to be dried to reduce the heat consumption and moisture influence during the subsequent sintering process.
sinter:
Place the dried sintered sand into a high-temperature sintering furnace for high-temperature sintering treatment.
The sintering temperature and time need to be adjusted according to the type of raw materials and required properties to ensure the compactness and strength of the sintered sand.
Cooling and post-processing:
After sintering, the sintered sand should be cooled naturally or forcibly.
After cooling, the sintered sand undergoes post-treatment processes such as inspection, grading, and packaging.
2、 Precautions for Using Sintered Sand
Pre use inspection:
Before using sintered sand, it is necessary to check whether its appearance, color, particle size, etc. meet the requirements.
Avoid using sintered sand with cracks, damage, or excessive impurities.
Correct selection of usage scenarios:
Choose the correct usage scenario based on the performance and purpose of sintered sand.
Avoid using sintered sand in high temperature, high pressure, or corrosive environments beyond its tolerance range.
Reasonable storage and transportation:
Sintered sand should be stored in a dry and ventilated warehouse to avoid moisture and contamination.
During transportation, the sintered sand should be protected from damage such as compression and collision.
Safe use:
When using sintered sand, appropriate protective equipment such as gloves, masks, etc. should be worn.
Avoid prolonged exposure to sintered sand to reduce irritation to the skin and respiratory tract.
In summary, the production process and usage precautions of sintered sand are crucial for ensuring its quality and application effectiveness. During the production process, it is necessary to strictly control key parameters such as raw material quality, mixing ratio, sintering temperature, and time; During use, it is necessary to choose the correct usage scenario based on the performance and purpose of the sintered sand, and pay attention to safe use and reasonable storage and transportation.
