Chemical Liquid Solidification TRIZ Cases
- Lead Recycling via pH-Controlled Salt Precipitation Purification
pH-driven precipitation and redissolution purify lead from spent lead-acid batteries while avoiding smelting cost and harmful byproducts.
- Lead Recycling via pH-Controlled Salt Precipitation
pH-driven lead salt precipitation replaces battery smelting to purify recycled lead with lower cost, simpler equipment, and fewer harmful byproducts.
- Multimodal Polyethylene Pipe Composition for Hydrostatic Pressure Resistance
Deep hydrogen removal between reactors enables a multimodal polyethylene pipe composition with higher impact strength and 12.5 MPa pressure resistance.
