How to Measure the Quality of Foaming Agents?

How to Measure the Quality of Foaming Agents?

There are mainly three indicators: foamability, foam toughness, and bleeding.

1.    Foamability reflects the foaming ability of foaming liquid, which can be indicated by foaming height and foaming multiple. The higher the foaming height and foaming multiple are, the stronger the foamability of the foaming agent is.

2.    Foam toughness is the characteristic that the foam will not be damaged within a specified period of time in the air, which is often indicated by the half-damage time that how long will half of the foam be damaged, and the settlement distance that how much the foam column will settle in unit time. The longer the half-damage time is, the better the foam toughness is. The smaller the settlement distance is, the better the foam toughness is.

3.    Bleeding refers to the volume of aqueous solution produced after foam is destroyed.

Characteristics of Various Foaming Agents:

Commonly used foaming agents include protein based foaming agents, synthetic foaming agents, rosin foaming agents, etc. Different types of foaming agents have different foamability and the foams produced have different foam stability. Each type of foaming agents has its own limitations. For example,

1. The foam stability and the foaming multiple of rosin foaming agents are not so good, so it can only be used for foamed magnesite cement with the bulk weight more than 600㎏/m³, and cannot be used for the low-density foamed magnesite cement with the bulk weight less than 500㎏/m³;

2. The foamability and the foam stability of protein based foaming agents are relatively better, but the foaming viscosity is large, which is not conducive to mechanized production; 

3. Compound foaming agents have better foamability and foam stability.
