1. Physical and chemical properties of 'Huahui Brand' nickel iron ore powder pellet binder:
1. Appearance: white or yellowish powder.
2. Ingredients: The main raw material is cotton, added with acid, alkali and other chemical solvents, and formed through a series of complex chemical reactions.
3. Carbonization temperature: 230℃, combustion temperature: 375℃. The combustion products are mainly CO2 and H2O.
4. Colloidal properties: After the composite binder is dissolved in water, it forms a light yellow transparent colloid with a certain consistency and adhesive force. The colloid has strong stability, is not easy to decompose, and can be stored for a long time without deterioration.

'Huahui Brand'The preparation of metallurgical pellets of iron fine powder briquette adhesive/binder is an important part of the metallurgical process. It can not only improve the metallurgical physical and chemical properties of the material, but also realize the industrial solid waste resources An important way to utilize and circular economy. Cold-set molding technology can not only improve its combustion or reaction performance, but also reduce the formation and emission of pollutants through the addition of removal agents. Therefore, cold-pressed pellet technology is an important way to achieve energy conservation and utilize waste resources. For this reason, our company proposes a series of cold-setting pellet binders.
-
1. Wide adaptability: This binder is particularly suitable for the production of cold-set pellets from iron ore powder, chromium ore powder, phosphate rock powder, copper, lead, zinc, nickel and other non-ferrous mineral powders that are difficult to form. It does not require sintering and can be directly smelted or Calcined.
2. Easy to use: directly mix steel slag powder, binder and water in proportion to form.
3. Excellent performance: one-time molding, high molding rate, the wet ball will not fall apart when it is 2 meters high, it can be dried naturally or in the oven, the strength after drying is more than 100kg/ball, and it can withstand high temperature of 1200℃ without falling apart or powdering.
4. It does not contain various metal elements and does not affect the quality of the pellets.
-
1. Strong adhesion: the sludge pellet forming rate is high.
2. High compressive strength, the wet ball will not fall apart after falling to the ground two meters away.
3. It has high hardness after drying and the pressure resistance strength is above 1000N.
4. The product is environmentally friendly: it does not contain sulfur, phosphorus and other elements that are harmful to steelmaking.
-
Pellets produced using drying-free binders do not need to be dried or aired. Wet pellets are stacked directly. The stacking height can reach more than 3 meters, and can be stacked indoors or outdoors. After natural stacking for 3-5 days, the strength reaches over 1000N.
