Product technical advantages.

The production process is simple to operate and easy to control. At present, most manufacturers are facing the problem of instability in production, the foaming height cannot be controlled, and the size of the bubble cells is not large.

First, the density is difficult to adjust, the strength is difficult to guarantee, and the production efficiency cannot be improved.

The foaming is stable, and the collapse and cracking of the foaming process are prevented. The stirring time is less than one minute to produce slurry and foam, the mold can be stationary or orbital moving, without affecting the foaming effect, the bubble hole is uniform, and the hole wall is smooth and shiny. Foaming time The foaming amount can be adjusted, the strength development is fast, the mold turnover rate is high, the density is low, the strength is high, the thermal conductivity is low, the shrinkage is small, and the carbonization resistance is strong.

It has strong adaptability to different varieties of cement and fly ash in various places, and has better freeze-thaw resistance effect for northern climate, and can achieve a low density of 140-160kg cubic meters.

Cement foaming agent generally uses hydrogen peroxide, the production of hydrogen peroxide is not something that ordinary people can do, it is estimated that you are asking about the foam stabilizer, the foam stabilizer formula, the use of foam stabilizer mother liquor FL-6 triethanolamine water, stir and mix evenly.

Alas! How to say it! I don't understand!

How can the formula of the foaming agent be given casually.

The raw material formula of cement foaming agent is water, bone glue, urea-formaldehyde resin, sodium dodecylbenzene sulfonate, and triethanolamine.

Cement blowing agent refers to an admixture that can reduce the surface tension of the liquid and produce a large amount of uniform and stable foam to produce foamed concrete. Foaming agent is a kind of substance that can produce a large amount of foam when the aqueous solution is introduced into the air by mechanical force, and this kind of substance is surfactant or surfactant.

The production method of cement foaming agent: first mix the appropriate bone glue and urea-formaldehyde resin with 10 times the water, and the temperature reaches 75 degrees, and then heat the melt for about half an hour to form glue. Then it is mixed with sodium dodecylbenzene sulfonate, triethanolamine, etc., heated at a temperature of 75 degrees for about 5 to 10 minutes, and finally diluted with water to make a product.

Definition of cement blowing agent

Cement blowing agents belong to a category of narrow blowing agents, not all narrow blowing agents. In the narrow sense of foaming agent, only a very small part can be used for foam concrete, which is determined by the characteristics and technical requirements of foam concrete.

In industrial production and daily civil use, the use of foaming agents is very different, and different application fields have different technical requirements for foaming agents. For example, the blowing agent for fire extinguishers only requires its instantaneous foaming capacity and the ability of the branch balance to block oxygen, but does not require its high stability and delicacy. Another example is the flotation foaming agent for mining, which only requires it to have strong adsorption and good foaming power to the target, and does not have high requirements for foaming multiple and foam stability.

Foamed concrete is a common building material that contains water, cement, sand, gravel, and plasticizers. The specific recipe is as follows:

Sand, gravel and cement: This is the main component of foamed concrete, sand and gravel are the main materials that provide fill and strength, and cement is the main material that plays a binding role.

Plasticizers: Plasticizers are designed to increase the plasticity and toughness of foamed concrete. Commonly used plasticizers are emulsifiers, thickeners and toughening agents.

Pneumatic agent: The pneumatic agent is used to act as a foam. The commonly used air pressure agents in foamed concrete are hydrogen oxide and sodium chloride.

Other additives: Other additives can also be added to foamed concrete, such as anti-fire, antioxidants, antibacterial agents, etc.

Common foamed concrete formulations are as follows:

Basic formula: The ratio of sand, gravel and cement is usually 3:2:1, that is, 3 parts sand plus 2 parts gravel and 1 part cement.

Plasticizer formulation: The dosage of plasticizer is generally about 1%-3%.

Pneumatic agent formulation: The dosage of pneumatic agent is generally around.

Note: The formula of foamed concrete needs to be adjusted according to the specific use requirements, and different formulas have different properties and should be based on.

Cement has become something that can be seen everywhere, because the house we live in uses cement, and the road we walk also has the composition of cement, bricks to be built with cement, some templates to cement to plasticity, cement seems to be pervasive in our lives, but, for inventors, simple cement is not able to meet modern needs, so foamed cement appeared, this material, we call it a new type, thermal insulation lightweight material. Do you know the formula of foamed cement? Do you know its market price?

Today, I will explain it to you in detail. 

1. Foamed cement formula:

Foamed cement, the most important formula is the foaming agent, this is called the foaming agent, is the raw material of foamed cement, the foaming agent is fully "foamed" by mechanical means, and the foam and cement slurry are fully mixed together, and then the foamed cement is poured and shaped through the pumping system of the foaming machine to form a new material - foamed cement.

The most important feature of this kind of cement is that the material itself can fully act with the foaming agent, and it does not need to be like the traditional cement, the production process is heavy, and the process is more short, generally fifteen to two minutes. Moreover, the formula of this cement is more resource-saving and cost-saving, and the foamed cement made by the letter is not only able to replace cement in some aspects, but also derives a series of new functions.

Second, foamed cement **

Generally speaking, the foamed cement is in the range of 150-300, and it also depends on the quality of the foamed cement, the production process, the quality of the raw materials, and how much you need, the more you need, the unit price of foamed cement will be correspondingly lower, and the demand is less, the unit price will be higher, the unit price here is the first cubic meter of foamed cement required.

After a detailed analysis of foamed cement and foamed cement, do you know more about foamed cement and foamed cement? In this ever-developing society, similar to foamed cement so low, the use of large items will only be more and more, and in everyone's life, a lot of cement is used in the place, you might as well try to choose foamed cement, this new type of material, not only can make our environment better and better, but also can save a lot of money, practicality is also good, why not.

You can get it for free

Foam concreteThe main formulations are cement, water, fly ash, foaming agent, aggregate, and admixture。Other ingredients can also be added upon request, such as:Chopped fibers, organic polymers, etc。Cement is the primary influencing factor of the strength of foam concrete, and it is also the main one.

Absolute dry density per design.

of foamed concrete have an optimal amount of cement.

Fly ash is wide and low, and it has a certain activity, which can significantly improve the strength of foam concrete and improve the effect after molding. There are many substances that can produce foam, but only the foam produced does not break when mixed with mortar, and is stable enough for cementitious materials.

The coagulation and hardening are not affected before they can be used to prepare foaming agents. Admixtures commonly used for foam concrete are:Dispersants, waterproofing agent, early strength agent, quick-setting agent.

Foamed concrete: a new type of lightweight insulation material.

You just started to produce without professional foaming agent and foaming machine, our factory uses hydrogen peroxide to make foamed cement insulation board The effect is very good, the key is the process. Foamed cement insulation and strength has always been a contradiction, balancing foamed cement insulation and strength, there is a certain degree of difficulty, the need for industry people to make persistent efforts.

I have a recipe that is being produced and you can make an area**.

Isn't it useless to talk about this here? Hehe.

The product uses animal protein in nature as the main raw material, and the appearance is a dark brown liquid with a pH value. Its outstanding features are: the foam is particularly stable, the most suitable for the production of ultra-low density foam concrete, especially the density of 200 500kg m3, because even if the foam content is extremely high, it is not easy to defoam the collapse mold, the pouring stability is still very good, the foamed concrete made of high strength, is a new type of environmentally friendly, efficient cement foaming agent.

At present, the widely recognized blowing agent in the world is the animal protein blowing agent. It has been widely used in industrially advanced countries, such as Japan, the United States, Italy and other countries.

You're talking about cement expanders.

Cement expansion agent is a chemical admixture, added to cement, when the cement is set and hardened, the volume expands, and plays the role of compensating for the prestress of shrinkage and tension steel bars and fully filling the cement gap. In fact, cement expansion agent is the use of light metals (mainly aluminum powder, in recent years, iron powder, aluminum powder, etc.) and alkaline cement to produce hydrogen, and the cement volume expansion, play a role in improving the strength of cement, so it is also called cement foaming agent. It should have the following properties:

1) The foaming speed should be appropriate, too fast and too slow will affect the quality of concrete.

2) The hydrogen bubbles generated should be small in diameter and evenly dispersed. In particular, the pouring injection mold under the full volume of cement slurry needs to be evenly dispersed in order to ensure the quality of the pouring mold.

3) When producing gas, it shall not affect the coagulation and solidification of cement. If the cement setting is delayed, the cement strength will be reduced or the cement will be abnormally coagulated.

Isn't it?

Rosin: 4-6, sodium hydroxide: 2-3

Bone glue: 1-5, triethanolamine: , corn starch: , water: 84-92 parts.

The most important aspect of foaming is to control the ratio of gas to liquid. If the high-pressure air enters too much, there is more gas and less water, and the foam volume is very small, that is, it cannot form a liquid film, and the air cannot be surrounded by the foaming liquid film, and the foaming rate is low. If the foaming liquid enters the machine too much, there is more water and less gas, the emulsion will be formed, the foam is unqualified, the foaming liquid is wasted, and the foam output is low.

The right ratio of the two is the key to successful foaming.

Adjusting this ratio can be operated manually or fully automatically controlled by computer. Manual control is adopted, the process is simple, but the human factor is large, and the control is not sensitive and accurate; Fully automatic computer control, equipment investment increases, but not affected by human factors, accurate proportion, good foaming effect and high efficiency. When foaming, it is necessary to control the foam quality, which can be controlled by adjusting the foaming mechanism1 (except for special needs):

The foam is uniform and consistent, avoiding large and small; In addition, it is necessary to prevent the appearance of emulsions with more water and less gas, and reduce the rate of water secretion.

Attention should be paid to the treatment of foaming liquid. It is necessary to determine the specific ratio to ensure the quality of the finished product to avoid serious losses.
