What can foam hand wash directly squeeze out of foam? Jul 30, 2021
The principle of foam hand washing is that the bottle mouth has special device to make air mix with foaming agent. No one has ever seen a foam gun for fire fighting. The middle school must have done such an experiment. The drooping slip of the paper moved to the place where the gas flowed, because the fluid had the pressure reducing effect. The middle of the foam gun was a common gun head, and there was a set of holes with many sides on the outside. The foam agent was sprayed out from the middle of the sleeve, because the air pressure was reduced, and a large amount of air was sucked in from the side and mixed with foam.

The advantages of foam hand sanitizer are:

1, easy to use: the pump head is extruded out of foam, eliminating the process of washing and foaming.

2. Dosage saving: each use is 1 / 2 of the amount of ordinary hand sanitizer.

3, double effect: direct frothing, not easy to fall, so that the effective ingredients in the foam are fully utilized, greatly improving the effect of cleaning, sterilization and moistening.
