Plusieurs méthodes de fabrication d'agent moussant de ciment

The cement agent moussant is the core material in foam concrete. The only good cement foaming agent can make high-performance foam concrete products. Today I will share with you how to make a cement foaming agent. Mainly introduce five kinds of cement foaming agents, they are magnesium oxychloride cement foaming agent, rosin soap cement foaming agent, Agent moussant de ciment pour béton au jaune d'œuf, concrete composite foaming agent, engineering cement foaming agent.

1. Agent moussant de ciment à base de savon à la colophane: start to mix rosin and caustic soda, mix and heat; puis dissoudre le superplastifiant SM, acide citrique et poudre de silicium dans l'eau, put the above two mixtures by heating and heat preservation Mix in a heating container, ajouter de l'eau et mélanger uniformément, and mix the required amount of powder into the above-mentioned secondary mixture. Par rapport aux compétences existantes, 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.

2 the concrete composite foaming agent: contains the following processes: 1. Fabriquer un agent imperméabilisant approprié; 2. Make a fixed amount of foaming agent; 3. Make some compound foaming agent; 4. Write foam through foaming to the foam The concrete mixture is mixed and then cast into shape. After adding the waterproof concrete composite foaming agent prepared by the above method, the foam concrete can overcome the shortcomings of its large water absorption rate, so that the waterproof thermal insulation and thermal insulation functions are improved.

3 Agent moussant de ciment pour béton au jaune d'œuf: made by the following methods: firstly mix cement, poudre de céramique, eau, etc.. selon un certain rapport de masse, mélanger uniformément et préparer un coulis de béton de ciment. The egg yolk, stabilisateur, dispersant, conservateur, and water are mixed according to a certain mass ratio to form a uniform and fine closed-cell foam. Take a certain volume of the foam to join the cement concrete slurry, mélangez-le uniformément, and then cast it into a mold for maintenance. The cement foaming agent has easily obtained materials and simple foaming technology and overcomes the disadvantages of poor stability of traditional surfactants, lack of animal and plant protein-based cement foaming agents, and high cost.

4. Agent moussant pour ciment à l'oxychlorure de magnésium: firstly mix the appropriate bone glue and urea-formaldehyde resin and participate in 10 times of water. After the temperature reaches 75 degrés, heat and smelt for about half an hour to form a glue solution, and then dodecyl benzenesulfonate Sodium, triéthanolamine, etc.. sont mélangés. After the temperature reaches 75 degrés, it is heated for about 5-10 minutes, and finally diluted with water to make a product. Caractéristiques: The quality of the goods is good, the cost is low, et la méthode est très simple.

5. Agent moussant pour ciment pour l'ingénierie: Common are linear alkyl sulfate, foam stabilizer alkyl alcohol amide, fatty alcohol polyoxyethylene ether sodium sulfate, chlorure de calcium auxiliaire, et ainsi de suite. La technologie de fabrication est la suivante: 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.
