Higher foamingpressure will lead to smaller cell size. However, too high foamingpressure may lower the void fraction.
增大发泡压力有利于减小泡孔孔径,但压力过高会降低发泡硅橡胶的孔隙率。

It was found that an uniform temperature environment is the key to the preparation of carbon foams with uniform pore size and that the foamingpressure is the main factor for the control of pore size.
Thee working principle of polyurethane foaming machine has three kinds, such as high speed impeller type, high pressure air type, low pressure type and so on.
