What is a foaming agent? The function and use of foaming agent

1. What is foaming agent

Foaming agent is a substance that makes the target substance into pores. In a broad sense, foaming agent refers to all surfactants or surfactants whose aqueous solution can produce a large amount of foam when introduced into air, including most surfactants and surfactants. Active substances; foaming agents in the narrow sense refer to those that not only can produce a large amount of foam, but also have excellent properties, can meet the technical requirements of foaming of various products, and can really be used to produce actual surfactants or surfactants. Active substances.

There are many types of foaming agents, including rubber foaming agents, glass foaming agents, cement foaming agents, concrete foaming agents, plastic foaming agents, polyurethane foaming agents, etc., which can be roughly divided into chemical foaming agents and physical foaming agents and surfactants three categories.

2. The function and use of foaming agent

As a kind of adhesive, foaming agent is more popular because of its convenient operation, non-toxic and harmless, and moderate price. Foaming agent is used in many places. You may not know much about the function and use of foaming agent. The following is for everyone. A brief introduction.

The main function of the foaming agent is to decompose the target material into pores. The volume after foaming is several times or even more than ten times the original volume. Because of its good surface activity, it can reduce the surface tension of the liquid. After foaming and curing, it can play the role of bonding, sealing and leak-proof.

Commonly used foaming agents are mainly used in home leak-proof, leak-plugging and decoration, such as blocked gaps in doors and windows; in addition, industrial foaming agents are also widely used, and can be used in automobile parts sealing, the manufacture of some electrical appliances, and aviation and electronic equipment.

3. How to use the foaming agent

1. Before using the foaming agent, you need to observe the construction surface. If there is dust or fine soil, you need to wipe it off, and then spray less water on the surface. Shake the foaming agent a few times to operate the construction.

2. The foaming agent can be waterproof and sealed only after spraying and curing. There is no need to get clothes or hands before curing. The higher the temperature, the shorter the curing time. If the temperature is lower, it will take more time to cure. The construction temperature is 18 to 25 degrees. If the temperature is lower, the foaming agent can be preheated first.

3. During the construction of the foaming agent, it needs to be matched with a matching glue before it can be used. Hold the middle of the jar with your hand, and then gently pull the handle, and the material can be sprayed out to continue the construction. During construction, the jar needs to be turned upside down, and the spray needs to fill half of the object, because it will expand after curing, and the excess can be scraped off with a tool before curing.

4. After use, you need to clean the glue with a lot of water to facilitate the next use. The remaining foaming agent is sealed to prevent volatilization and solidification, resulting in waste.
