foam concrete block making machine for tunnel lining filling
foam concrete block making machine for tunnel lining filling is a device that can make foaming agent a certain concentration of an aqueous solution into foams. The foaming agent itself does not automatically become foams, it must pass the mechanical action of the foam concrete machine to become foams.
The foam concrete block making machine for tunnel lining filling and the foaming agent are a technical system that cooperate with each other and cannot function alone. No one can do without it. Between the two, we can’t say who is the main, who is the second, and its role is quite.
Without foaming agent, the foam concrete machine will not come out of the foam and lose its value. Similarly, without a foam concrete machine, the foaming agent is no better, it cannot be foams, and its use is lost.
