Which building materials use HPMC?

1. Cement-based mortar

In construction projects, cement-based mortar is a common adhesive used for masonry, plastering, etc. The application of HPMC in cement-based mortar is mainly reflected in the following aspects:

Water retention: HPMC has excellent water retention performance, which can prevent water loss too quickly during the hardening process of mortar, thereby extending the operability time of mortar and ensuring that the mortar has sufficient strength and durability.

Improve construction performance: It can improve the fluidity and lubricity of mortar, making it easier to spread and level during construction.

Anti-shrinkage and cracking: By controlling the evaporation of water in mortar, HPMC can effectively reduce shrinkage and cracking during the drying process, improving the overall quality of mortar.

2. Tile Adhesive

Tile adhesive is mainly used for laying tiles and stones, requiring high bonding strength and good construction operability. The main functions of HPMC in tile adhesive include:

Enhancing bonding strength: HPMC can significantly improve the bonding performance of the adhesive, making the bond between the tile and the substrate more solid, reducing hollowing and falling off.

Water retention: Water retention is an important characteristic of tile adhesive. HPMC enables the adhesive to maintain sufficient moisture even in high temperature or dry environment to ensure the bonding quality.

Construction operability: It can also improve the fluidity and construction of the adhesive, making tile laying more convenient and quick.

3. External Insulation System (EIFS)

External insulation system is a common energy-saving technology in modern buildings, involving the use of insulation boards and plastering mortar. Among these materials, HPMC plays an important role:

Improving the bonding strength of plastering mortar: HPMC helps to improve its bonding strength in insulation mortar, so that it can better adhere to the insulation board and wall surface.

Prevent cracking of plaster mortar: HPMC's water retention property allows plaster mortar to retain sufficient moisture during the hardening process to avoid cracking problems.

Convenient construction: By adjusting the consistency and construction performance of the mortar, HPMC makes the construction of the exterior wall insulation system smoother.

4. Gypsum-based materials

Gypsum-based materials are widely used in interior decoration, such as gypsum putty, gypsum board, etc. Among these materials, HPMC also plays an important role:

Improving water retention: In gypsum-based materials, HPMC can extend the operability time of gypsum materials and ensure the uniformity and surface quality of the materials.

Improving film-forming properties: HPMC's film-forming properties help the surface of gypsum materials form a smooth and uniform film layer, improving its decorative effect.

Enhancing anti-sagging properties: When constructing on vertical surfaces, HPMC can effectively prevent the sagging of materials, making the use of gypsum putty smoother.

5. Self-leveling mortar

Self-leveling mortar is a material used for ground leveling with good fluidity and self-leveling properties. The role of HPMC in self-leveling mortar includes:

Improving fluidity: HPMC increases the viscosity and lubricity of the mortar, enhancing its fluidity, allowing it to spread quickly and level automatically during construction.

Improving water retention: HPMC maintains moisture in the self-leveling mortar, preventing it from drying too quickly during the leveling process, and ensuring its final strength and wear resistance.

Reducing stratification: It can also prevent stratification of the mortar when it is stationary, ensuring that the material is uniform throughout the construction area.

6. Putty powder

Putty powder is the basic material for the construction of interior and exterior walls of buildings. HPMC plays a very important role in putty powder:

Improving water retention: HPMC can keep putty powder moist and avoid cracking and powdering caused by drying too quickly during construction.

Improving construction performance: By increasing the smoothness and viscosity of putty, HPMC improves the convenience of construction and ensures that the putty is smoother when the wall is constructed.

Cracking resistance: During the drying process, HPMC can effectively reduce the cracking of the putty layer and ensure the smoothness and durability of the wall.

7. Waterproof coatings

Waterproof coatings are used for waterproofing projects in buildings, such as roofs, basements, bathrooms, etc. In waterproof coatings, HPMC provides important modification effects:

Improving water retention and crack resistance: HPMC uses its water retention properties to prevent cracks in waterproof coatings during the drying process and ensure that they form a complete waterproof layer.

Enhancing coating adhesion: It can also improve the adhesion of the coating, allowing it to better adhere to the surface of the substrate and ensure the uniformity and thickness of the coating.

8. Concrete additives

HPMC is also widely used in concrete to improve the construction performance of concrete:

Enhancing crack resistance: HPMC can reduce shrinkage and cracking during the drying process by improving the water retention of concrete.

Improving fluidity: In concrete with high fluidity requirements, HPMC can provide better construction operability, especially in complex building structures.

As an efficient building material additive, HPMC has been widely used in various aspects of construction projects. Its main functions include water retention, thickening, enhancing adhesion, improving construction operability, etc. By adding HPMC to different building materials, the quality and construction performance of building materials have been significantly improved. In modern construction, the importance of HPMC is becoming more and more significant. It not only improves construction efficiency, but also improves the durability and aesthetics of buildings.
