| titleOfInvention | Casting membrane liquid, ultrafiltration membrane and method for preparing ultrafiltration membrane |
| abstract | The invention provides a membrane casting solution, an ultrafiltration membrane and a method for preparing the ultrafiltration membrane. Wherein, the casting solution comprises: a polyamide; a pore-forming additive; and a solvent, wherein the relative molecular mass of the polyamide is 20 to 30 ten thousand. Therefore, the viscosity of the casting solution is proper, and the casting solution has almost no bubbles, thereby being beneficial to film formation. |
