High expansion foam discharge
WebHI-EX foam concentrate can be used to produce foam with expansion ratios ranging typically between 200:1 and 1000:1 depending upon the type of generator and the operating pressure. For this reason, it is important, for the proper design of a high expansion system, that the concentrate be specifically tested with the intended foam generators. Web12 de dez. de 2016 · The foam with expansion ratio between 1:2 and 1:20 is called low expansion foam. Foam with expansion ratio between 1:20 and 1:200 is called medium expansion foam. Foam with expansion ratio above 1:200 is called high expansion foam. Drainage time. Drainage time is the measure of how quickly a foam solution can move …
