In the construction and decoration industry, hollow tiles and falling tiles have always been the most persistent pain points for both homeowners and contractors.

Modern tiles (such as porcelain tiles and full-polished tiles) feature high density and low porosity. Traditional bonding materials face two major challenges:<\/span><\/p>

  1. Poor Wettability<\/span><\/strong>: Cement mortar cannot effectively wet the tile backing, relying solely on insufficient mechanical interlocking.<\/span><\/p><\/li>

  2. High Shrinkage<\/span><\/strong>: Chemical and drying shrinkage occur during cement hydration, creating internal stress at the interface, which over time leads to hollowing.<\/span><\/p><\/li><\/ol>

    To solve these two pain points, the core lies in\u00a0<\/span>reducing the water-to-cement ratio<\/span><\/strong>\u00a0\u03ba\u03b1\u03b9\u00a0<\/span>increasing compactness<\/span><\/strong>.

    Polycarboxylate superplasticizer (PCE) is not simply about “making water thinner.” In tile adhesive systems, it acts as a “dispersion master.”<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    TENESSY’s high-efficiency superplasticizer features a comb-shaped molecular structure that uniformly disperses cement particles through both electrostatic repulsion and steric hindrance. This releases water that would otherwise be needed to coat particles, significantly reducing water demand while maintaining excellent workability.<\/span>
    Customer Benefit<\/span><\/strong>: Lower water-to-cement ratio directly reduces the number of capillary pores in the cement stone. The denser the matrix, the harder it is for external moisture (especially chloride-containing rainwater) to penetrate and corrode the bond layer, effectively eliminating freeze-thaw damage and efflorescence.<\/span><\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
