FAQ
Here are frequently asked technical questions. Contact us if you need more help.
How should high-range water-reducing admixture be properly stored and used?
+High-range water-reducing admixture should be stored in a cool, dry, and well-ventilated warehouse, away from direct sunlight and high temperatures. When using it, the recommended dosage in the product instructions should be followed, as excessive use may affect its performance. After opening, it should be used as soon as possible to avoid prolonged exposure to air, which may reduce its effectiveness.
What is the relationship between the curing time of the binder and temperature?
+The curing time of the binder is closely related to temperature. In general, the higher the temperature, the faster the curing speed; the lower the temperature, the slower the curing speed. In low-temperature environments (below 10°C), the curing time will be significantly extended, and appropriate insulation measures are recommended. For the specific curing time, please refer to the product technical data sheet.
How does the particle size distribution of the micropowder matrix affect product quality?
+The particle size distribution of the micropowder matrix directly affects the product’s bulk density, flowability, and sintering performance. If the particle size distribution is too narrow, the bulk density may decrease; if it is too wide, the uniformity of the product may be affected. Our products undergo precise particle size control to ensure optimal performance.
What precautions should be taken in the forming process of ceramic granulated powder?
+When forming ceramic granulated powder, the following points should be noted: 1) Control the moisture content appropriately, generally between 5% and 8%; 2) Adjust the forming pressure according to the product specifications; 3) Avoid deformation of the green body during demolding; 4) Carry out the drying process slowly to prevent cracking. For specific process parameters, please refer to the application guide.
