Qu'est-ce que la colle à carrelage et ses classifications ?

In the process of decoration, one of the materials frequently used is tile adhesive, which ensures a better fit when tiling.

I. What is Tile Adhesive?

Powder tile adhesive is a cement-based tile mortar modified by polymers. Its main raw materials include cement, quartz sand, calcium carbonate, HPMC (hydroxypropyl methylcellulose), rubber powder, wood fiber, and starch ether. Additionally, powder tile adhesives sometimes contain various additives, particularly those tailored to enhance the functionality of the adhesive. Cellulose ethers, which provide water retention and thickening effects, and latex powders, which can increase tile adhesion, are added to ordinary tile adhesives. Common additives in latex powders include vinyl acetate/vinyl ester copolymers, vinyl laurate/ethylene/vinyl chloride copolymers, and acrylic acids. The addition of latex powder can greatly increase the flexibility of tile adhesive, improve stress resistance, and enhance flexibility.

Furthermore, other additives are incorporated into tile adhesives with specific functional requirements. For instance, wood fiber is added to improve the crack resistance and open time of the mortar, modified starch ether is added to provide anti-slip properties, early strength agents are added to quickly increase the strength of the tile adhesive, and hydrophobic agents are added to reduce water absorption and provide waterproof functionality. However, liquid tile adhesive is a single-component, water-based, environmentally friendly material specifically designed for tiling. It has a special structure and is made from raw materials such as acrylic copolymers and additives synthesized through scientific and technological methods.

II. Classification

Foshan Puhui New Materials Co., Ltd. mainly introduces the classification based on functionality.

Ordinary Tile Adhesive: It possesses good flexibility, impermeability, crack resistance, aging resistance, high temperature resistance, freeze-thaw resistance, non-toxicity, environmental friendliness, and ease of application.

Polymer Tile Adhesive: It exhibits strong adhesion, good water resistance, excellent durability, ease of operation, and high shear performance. It serves dual functions as both an interface agent and an adhesive.

Heavy Tile Adhesive: Designed specifically to address the issue of ordinary tile adhesives being unable to bond heavy tiles, heavy tile adhesive can effectively adhere tiles to surfaces, solving the problem of ordinary adhesives failing to bond to tiles. It can completely replace dry-hanging supports, saving construction costs.
