What is the method of using a concrete foaming agent?

What's a concrete foaming agent? Concrete foaming agent is also called foam concrete foaming ingredient. It reduces the liquid's surface tension to form uniform, stable foams that can then be used in the production of foam concrete admixture. Foaming agents are substances that make their aqueous solutions produce large quantities of foam when a mechanical force is added to the air. It is also known as a surface-active substance or surfactant. Surface active activity is the essence of a foaming agent. The core of foaming is its surface active action. Without it, foaming agents cannot be made or become foaming agents.

Use concrete foaming agents
Concrete foaming agents fall under one of the narrower foaming agents. Only a small portion of narrow blowing agents can be used for foam concrete. It is determined by foam concrete's technical characteristics.
The use of foaming agents in industrial production is different from that used for daily civil purposes. Each application field has different requirements. An example of this is the fire extinguisher foaming material. It only needs its instantaneous foaming volume as well as oxygen barrier ability. However, it does not need to be more stable or delicate. A flotation foaming material used in mining is another example. It only needs to have a strong adhesive force and good foaming forces for the object, and it does not require a high foaming multiple nor foam stability. This is just a small sample of the many uses for foaming agents. It is widely used and can be found in many industries. There are different performance requirements in each industry for foaming agents. One industry might not use the same foaming agent, while another may find it ineffective. Concrete foaming agents are also used for making concrete concrete to meet technical specifications. The agent is versatile and can generate large quantities of foam. It also takes into consideration the fragility of foam as well the flexibility of concrete and other cementing substances. These foaming agents are very limited and cannot be used for the production of concrete. Foaming agents for concrete foam must contain only a few surfactants and surface-active materials that can meet these technical specifications.

Use of concrete foaming agents
1. The concrete foaming agent concentration is usually high so the foaming machine can only produce low levels of foam and will waste it. The foaming agents used in direct-add machines are usually high-concentrated and cannot produce high quality foam. However, it is easy to jam the concrete foam machine into your pump. Both concrete foaming agent foaming effects and concrete foaming agent diluting are important. A good dilution is essential for concrete foaming agent dilution and foaming effect. The manufacturer's suggested dilution should be used to calculate the appropriate dilution. However, the test must be done in the foaming machine.
2. It is important to determine the mixture ratio and dilute the foaming agent with water. Then, you can make foam products using the foaming fluid. After the foaming agent has been fully dissolved, you can observe any blisters in the concrete. Then, mix the liquid with water to form a cylinder.

Dilute solution of zinc sulfate buffered with ammonium acetate is added to the saturated solution of H2Se, and H2Se gas diluted with N2 or H2 is added to the solution (formed by the reaction of Al2Se3 and dilute hydrochloric acid) . The precipitated vessel is heated over a steam bath and the excess H2Se gas is absorbed in a wash bottle containing concentrated nitric acid. If the zinc salt solution is introduced too fast or the concentration is too high, the white precipitate will be formed, and it will take a long time to change to the yellow ZnSe.Yellow ZnSe precipitates are difficult to filter and need to be separated by centrifugation. The separated precipitate was washed first with boiled dilute ammonia and then with methanol. The cleaned ZnSe precipitates were first dried in a vacuum dryer containing CaCl2.Then, It was dried in a dryer containing P2O5 AT 120 ° C.
Zinc selenide is very sensitive to air when it is wet. Therefore, the dried product needs to be placed in the glass tube, heated at 600 ℃, H2 or H2Se atmosphere for 2 ~ 4h, to remove the oxidized product.
2. A mixture of 4g zinc oxide, 2.5g zinc sulfide and 6g selenium was placed in a quartz crucible in the lid and heated at 800℃ for 15 minutes to obtain the ZnSe product.

Applications of Zinc Selenide ZnSe Powder:
ZnSe is grown in melt under excess inert gas pressure (usually Ar). When there is no absorption and inclusions, it is very suitable for 10.6 μm wavelength CO2 laser optics. Therefore, ZnSe is a very important infrared material. It has a very wide transmission wavelength range (0.45 ~ 21.5 μm). The refractive index of 550 nm (green) and 2.40 refractive index was 10.6 μm (LWIR). In addition, ZnSe applications include:
1. ZnSe can be used as a fluorescent material and a semiconductor dopant;
2. ZnSe is widely used in laser, medicine, astronomy and infrared fields.
3. Znse is used to make infrared transmitted materials and infrared optical instruments
4. ZnSe is used to form an II-Vi LED and diode laser. It produces blue light.
Cr Doped ZnSe (ZnSe: Cr) is used as an infrared laser gain medium with an emission wavelength of about 2.4 μm.
5. Activated ZnSe (ZnSe (TE)) is a scintillator having 640 nm, which is suitable for matching the photodiode. It is used for X-rays and gamma-ray detectors. The ZnSe scintillator is obviously different from the ZnS scintillator.
