Compared with rosin soap, the yield, and dosage of hot rosin polymer are much lower, making rosin soap less popular. This is mainly because the performance of rosin thermal polymer is equivalent to that of rosin soap. Still, its production cost and price are relatively high, which could be more conducive to market competition. In addition, its production uses phenol as the raw material, which is toxic and has production safety and environmental issues. All of this determines that it does not have many advantages, as it does not have as many advantages as rosin soap, so its promotion is limited. It is less widely used than pine soap. Therefore, this book will no longer provide a more detailed introduction.
After rosin-based foaming agents, China developed various synthetic surfactant-based foaming agents in the late 20th century. This type of foaming agent was widely used in cement foaming abroad in the 1950s, due to the underdeveloped surfactant industry in China at that time, it has yet to be developed and applied. It was not until 1980 that due to the large-scale development of China's surfactant industry, this type of foaming agent was gradually designed and became the mainstream product of foaming agents in recent years. Most of the cement foaming agents sold on the market are synthetic surfactants, accounting for approximately 60% of the total production and sales of foaming agents. According to the ionic properties of surfactants, synthetic surfactant foaming agents can be divided into anionic, cationic, nonionic, and zwitterion foaming agents. They are a large family with a wide variety, but there are only a few wide varieties with excellent performance. The main reason is that this type of foaming agent could be better in foam stability and suitable for low-density foam concrete. Among various synthetic surfactant foaming agents, anionic foaming agents are popular due to their fast foaming speed and high foaming times. Cationic foaming agents are expensive and have a particular impact on the strength of cement, so they are not widely used. The foaming ratio of nonionic foaming agents is generally tiny, and most people value their foaming ability, so they have yet to be widely used. The zwitterion foaming agent is not widely used, although foaming is acceptable due to its high cost. Below is a detailed introduction to the widely used anionic surfactants and a brief description of nonionic surfactants.
