The Difference Between Hydrophobicity and Hydrophilicity of Polyurethane Grouting & Plugging Liquid

The Difference Between Hydrophobicity and Hydrophilicity of Polyurethane Grouting & Plugging Liquid

1. Polyurethane grouting liquid or leak-plugging agent

Polyurethane leakage plugging agent or polyurethane grouting liquid is a polymer material with excellent precipitation performance and leakage plugging performance. It is widely used in pressure pipelines, storage tanks, containers, ships and other fields. There are many types of polyurethane leak-stopping agents, which can be divided into water-based polyurethane and oil-based polyurethane according to different applications. Hydrophobicity and hydrophilicity are also important factors in distinguishing polyurethane leak-stopping agents.

2. Hydrophobicity and hydrophilicity of polyurethane leak-stopping agent

Hydrophobicity refers to the property of a substance that does not easily interact with water and is insoluble in water. Hydrophilicity refers to the property of a substance that easily interacts with water and is easily soluble in water. The hydrophobicity and hydrophilicity of polyurethane leak-stopping agent determines which fields and occasions it is more suitable for use.

3. Application of hydrophobicity and hydrophilicity

For some oily liquids, hydrophobic polyurethane leak-stopping agents are more effective at sealing leaks. For water-based liquids, hydrophilic polyurethane leak-stopping agents are more suitable. In addition, depending on the application field and pressure level, the polyurethane leak-stopping agent selected may also be different.

4. The manifestation of hydrophobicity and hydrophilicity in oily polyurethane

Among oil-based polyurethanes, the stronger the hydrophobicity, the better the coagulation properties of the polyurethane leak-stopping agent, which is suitable for sealing in low temperature or high negative pressure environments. The highly hydrophilic polyurethane leak-stopping agent has a relatively long solidification time and is easier to function in an aqueous liquid environment.

In short, the hydrophobicity and hydrophilicity of polyurethane leak-stopping agents have an important impact on its application fields and effects. When choosing a leak-stopping agent , you need to make a choice based on factors such as the specific situation, environment, and liquid properties. In most cases, oil-based polyurethane has good hydrophobicity and water-based polyurethane leak-stopping agent has good hydrophilicity. In order to achieve better leak-stopping effect, both Can be mixed and used, and the specific proportion is adjusted according to project needs.
