It can be made by blowing, extrusion casting, solution casting, or by calendaring.
可通过吹膜、挤压铸造、溶液铸造或轧光工艺制造。

It is obtained that, firstly, the PVA hydrogels byextrusion have higher tensile strength than PVA hydrogels by the solution casting method.
结果表明,双螺杆挤出法制备的凝胶拉伸强度高于溶液浇铸法所得样品的拉伸强度。
3
The cereal product in solution providing a viscosity at least as great as the viscosity provided by the components of the cereal product prior to being extrusion cooked.
