Several simple manufacturing methods of cement foaming agent

Cement foaming agent is the core material in foamed concrete. Only a good cement foaming agent can produce high-performance foamed concrete products. Five kinds of cement foaming agents are introduced. They are magnesium oxychloride cement foaming agent and pine wood foam. Soap cement foaming agent, egg yolk concrete cement foaming agent, concrete composite foaming agent, cement foaming agent for engineering.

1. Rosin soap cement foaming agent: start to mix rosin and caustic soda, stir and heat; then dissolve SM superplasticizer, citric acid and silica fume in water, put the above two mixtures into water and heat and keep them in a heating container Mix, add water and mix evenly, add the required amount of rubber powder to the above for secondary mixing and mixing. The choice of composite foaming method greatly improves the quality of commercial foam compared to the prior art. The inner wall of the foam formed by the foam can also form a thin layer of polymer crystalline film with waterproof function. The mortar involved in the cement foaming agent also has a good thermal insulation function.

2. Concrete composite foaming agent: including the following processes

(1) Prepare a suitable waterproofing agent; (2) Make a quantitative foaming agent; (3) Prepare some composite foaming agents; (4) Write the foamed foam into the foamed concrete mixture, stir evenly, and then pour it into molding . After the waterproof concrete composite foaming agent prepared by the above method is added to the foamed concrete, the disadvantage of high water absorption rate can be overcome, so that the waterproof and thermal insulation and thermal insulation functions can be significantly improved.

3. Egg yolk concrete cement foaming agent: choose the following method to make: first mix cement, ceramic powder, water, etc. according to a certain mass ratio, stir evenly, and make cement concrete slurry. Then, egg yolk, stabilizer, dispersant, preservative and water are mixed in a certain mass ratio to form a uniform and fine closed-cell foam. Take a certain volume of foam to one side of the cement concrete slurry, stir evenly, and pour it into the mold for curing. The cement foaming agent has easily available raw materials and simple foaming process, and overcomes the disadvantages of poor stability of traditional surfactants, lack of raw materials, and high cost of animal and vegetable protein cement foaming agents.

4. Magnesium oxychloride cement foaming agent: first mix an appropriate amount of bone glue and urea-formaldehyde resin with 10 times the amount of water and stir evenly. After the temperature reaches 75 degrees, heat and smelt for about half an hour to form glue, and then add dodecyl Sodium benzenesulfonate, triethanolamine, etc. are mixed, heated for about 5-10 minutes after the temperature reaches 75 degrees, and finally diluted with water to make commercial products. Features: Good quality, low cost, and the method is very simple.

5. Cement foaming agent for engineering: commonly used linear alkyl sulfate, foam stabilizer alkyl alcohol amide and fatty alcohol polyoxyethylene ether sodium sulfate, auxiliary calcium chloride, etc. The manufacturing process is as follows: the components are stirred evenly at the normal temperature.

Synthetic blowing agent overview

Synthetic foaming agent for concrete is a highly concentrated and efficient liquid used to produce lightweight foam concrete, also known as cellular lightweight concrete (CLC).

CLC concrete has great potential to help build cellular lightweight applications. Using the right type of blowing agent can make a huge difference in product properties such as the mechanical properties of concrete and its resistance. Synthetic foaming agents are chemicals that reduce the surface tension of liquids and are widely used worldwide in the manufacture of blocks, bricks, CLC concrete, etc. When high density is required, less energy is required to form compared to other blowing agents. Highly recommended for the construction industry where the demand for lightweight concrete is increasing over time.

Advantages of synthetic foaming agent for concrete

1. Low cost/high concentration

The low usage of synthetic foaming agents for concrete is a factor that must be considered when choosing a foaming agent, not just its base price per liter.

2. Fine foam and good stability

It can be used in a wide temperature and water quality range. This stability means that the foam bubbles are able to sustain themselves and support the mortar around them. Air bubbles do not easily collapse, so foam concrete does not collapse when it is made or after it has been placed.

3. Less bleeding.

4. Excellent strength and thermal insulation properties.

This means that the foamed concrete produced by Tongrun foaming agent is suitable for a wide range of applications.

5. The foaming agent is basically harmless and easy to wash off.

 Instructions for use of synthetic foaming agent for concrete

The water and blowing agent are fed separately into the foam generator and mixed in the correct proportions (see picture below). The mixture of water and blowing agent is called a pre-foaming solution. Pre-foaming solution and compressed air through a lance;

Foaming agents can be used with all types of cement and are only incorporated into cement or sand cement mortars to produce foamed concrete of various types and for every application. Its cost is a small percentage of the total cost of foamed concrete, usually only about 1-3%.

Synthetic foaming agent application

1. Foaming agent is used to make lightweight (clc) blocks and panels;

2. Use a foaming agent to fill the voids;

Foamed concrete is also very useful for filling voids. Since it is so fluid, it will tip over even the most inaccessible places. It can be used for planned work as well as quickly providing stability and support in an emergency;

3. Foaming agent for roof insulation;

4. Foaming agent is used to mark CLC blocks, cast-in-place walls, bridge reinforcement wall construction, floor construction, lightweight prefabricated blocks, fire protection, sound insulation, etc.
