Saponin type foaming agent of cement foaming agent
The main component of saponin-type blowing agent is triterpenoid saponins, which are extracts from the fruit of Saponin, a perennial tree, and belong to nonionic surface-active substances. Saponins of triterpene are the main components of saponins of Saponin, the fruit of Saponin saponin, a perennial tree. It has excellent foaming properties. Triterpenoid saponins are composed of monosaccharides, glycosides and aglycones. The aglycone group consists of two connected aglycones. Generally, one aglycone can connect three or more monosaccharides to form a larger pentacyclic triterpene spatial structure. The monosaccharides in monosaccharides have many hydroxyl groups that can form hydrogen bonds with water molecules, so they have strong hydrophilicity. The aglycones in the aglycones have a hydrophilic (hydrophobic) group. Triterpenoid saponins are nonionic surfactants.
When the triterpenoid saponins are dissolved in water, the macromolecules are adsorbed on the gas-liquid interface, forming a directional arrangement of two groups, which reduces the tension of the gas-liquid interface and makes the generation of new surface easy. If the solution is stirred by mechanical method, bubbles will be generated. Due to the large molecular structure of triterpenoid saponins, the molecular film formed is relatively thick, and the elasticity and strength of the bubble wall are relatively high so that the bubbles can remain relatively stable. The foaming power of Saponin is temperature dependent, and the foaming power increases linearly in the range of 20 ~ 90℃. This shows that heating can promote foaming. But temperature also promotes defoaming, the higher the temperature, the faster the defoaming speed. Taking 5min of storage as an example, the decrease of 40℃ was about 2.9%, 80℃ was 8.7%, and 90℃ was 19.3%. Because the resources of saponin trees in China are not as rich as those of tea trees, the production scale of Saponin is not as large as that of tea saponin. The FP-5B foaming agent developed by us is modified Saponin. Given the excellent stability of Saponin and the deficiency that the foaming ratio is not as good as that of synthetic anionic foaming agents, to improve its foaming power, we added two kinds of foaming agents. Also, we added a foam stabilizer, making its foaming ratio exceed that of synthetic anionic surfactants, which is ideal, and further improving the foam stability, better than single component saponin. Especially suitable for the production of 500㎏/m sub-ultra-low density foamed concrete. But due to the shortage of raw saponin materials, production has been unable to go up; welcome readers to provide resource information.
