Phenolic resin special for foundry coated sand, mainly used for solid core and shell in the production of coated sand. It has the characteristics of high strength and low free phenol content
Instructions
3.1 Sand selection. When using, first select the particle size of the raw sand according to the requirements.
3.2 Fried sand. After selecting the particle size, weigh a certain weight of raw sand for frying.
3.3 Add phenolic resin. After the temperature reaches 130-150℃, add phenolic resin.
3.4 Gauto water solution. The amount of Utopia added is 12-20% of the resin addition.
3.5 Add calcium stearate.
3.6 Perform sand removal, crushing, screening, cooling, and storage.
4. Matters needing attention:
The resin must be stored in a ventilated and dry place. Avoid direct sunlight and keep away from heat sources. The storage temperature should not exceed 35°C. Do not stack the resin bag too high during storage. Tie the mouth immediately after use to avoid agglomeration.
