Requirements for extrusion die toolsing agents in the production of cemented carbide die tools:
1. It can wet the powder and give a certain bonding force between the powders. The use of low molecular weight ingredients or the addition of surfactants can significantly reduce the contact angle of the forming agent to the powder and improve the adhesion, but the dough must reach a certain level Hardness and strength, you need to add a certain amount of polymer substances.
2. It itself and its decomposition products are non-corrosive, non-toxic or low-toxic.
3. Each component of the forming agent can be dissolved in the same solvent.
4. It can be removed at low temperature without residue.
