1. Rosin soap cement foaming agent: start to mix rosin and caustic soda, mix and heat; then dissolve SM superplasticizer, citric acid and silicon powder in water, put the above two mixtures by heating and heat preservation Mix in a heating container, add water and mix evenly, and mix the required amount of powder into the above-mentioned secondary mixture. Compared with the existing skills, the method of composite foaming has been used to greatly improve the quality of commodity foams. The inner wall of the bubbles formed by foaming can also form a very thin polymer crystal film with waterproof function, participate in the cement foaming agent The mortar also has a good thermal insulation function.
4. Magnesium oxychloride cement foaming agent: firstly mix the appropriate bone glue and urea-formaldehyde resin and participate in 10 times of water. After the temperature reaches 75 degrees, heat and smelt for about half an hour to form a glue solution, and then dodecyl benzenesulfonate Sodium, triethanolamine, etc. are mixed. After the temperature reaches 75 degrees, it is heated for about 5-10 minutes, and finally diluted with water to make a product. Features: The quality of the goods is good, the cost is low, and the method is very simple.
5. Cement foaming agent for engineering: Common are linear alkyl sulfate, foam stabilizer alkyl alcohol amide, fatty alcohol polyoxyethylene ether sodium sulfate, auxiliary calcium chloride, and so on. The manufacturing technology is as follows: the ingredients are mixed and mixed evenly at room temperature. The invention can announce a white bubble with very high foaming power, excellent stability, and can be widely applied to the production of foamed concrete, foamed lightweight brick and bubble mixed lightweight soil, and is also suitable for earth pressure balanced shield Soil improvement in structural construction.
