Silicone hydrophobic powder SHP500, SHP600 is composed of compounds with long-chain hydrocarbon structures. Their molecules can interact with the surface tension in water and reduce the wettability of water to materials. When this substance is added to mortar, it can change the pore structure of cement-based materials at the microscopic level, thereby reducing the ability of water to penetrate.

The role of Silicone hydrophobic powder in mortar:

1. Reduce water absorption: By adding hydrophobic agent to mortar, the capillary suction of the material can be effectively reduced, which directly leads to a significant reduction in the water absorption rate of the mortar surface. This change means that even in rain or humid environments, the mortar is not easily penetrated by water and maintains a better dry state.

2. Enhance durability: Since the intrusion of water will trigger a series of chemical reactions, such as hydration, dissolution and freeze-thaw, these reactions will gradually weaken the structural strength of the mortar. The mortar treated with hydrophobic treatment has significantly improved its ability to resist these destructive processes, thereby improving the overall durability and service life.

3. Prevent biological attachment: The humid environment provides good conditions for the growth of microorganisms. When the moisture content in the mortar is reduced, the chance of biological attachment is also reduced, which is of great significance for preventing moss growth or bacterial growth.

4. Enhanced impermeability: The impermeability of mortar refers to the ability to prevent liquid from flowing through capillary pores. After adding water repellent, the impermeability of mortar is greatly improved, which helps to block the penetration path of pollutants and harmful substances and protect the safety and hygiene of the internal environment of the building.

5. Improve construction quality: Mortar treated with water repellent shows better plasticity and adhesion during construction. This not only facilitates construction operations, but also helps to form a more uniform and compact structural layer, thereby improving the overall quality of the final structure.

6. Energy saving and emission reduction: In many cases, the use of mortar treated with water repellent can reduce the use of other waterproofing measures, such as additional waterproof layers or coatings. This not only simplifies the construction process, but also helps to reduce the consumption of building materials and energy, which is in line with the concept of sustainable development.

7. Economic benefits: Although the initial investment may increase, considering the long-term reduction in maintenance costs and the extension of the life of the building, the use of water repellent is actually an economical and efficient decision.

In modern construction practice, the application of water repellent has become one of the important means to improve the waterproof performance of mortar. Through scientific formula design and reasonable construction technology, water repellent not only enhances the basic performance of mortar, but also shows its uniqueness in energy conservation, environmental protection and economic benefits.
