Case 1: Tile adhesive optimization in high temperature environment

• Formula adjustment: Select HPMC cellulose ether with good heat resistance and increase its dosage appropriately (such as 0.5%-1%). At the same time, add retarder (such as sodium gluconate). Delay the setting time of mortar.
• Construction process: Avoid construction during high temperature periods and use wet construction to ensure that the base is moist.
• Effect: The water retention and construction operability of the mortar are significantly improved, the bonding force is enhanced, and the construction quality is guaranteed.

Case 2: Tile adhesive optimization in low temperature environment

• Formula adjustment: Select cellulose ether with good low temperature performance (such as methyl cellulose ether, MC), and increase its dosage appropriately (such as 0.3%-0.5%). Add antifreeze (such as sodium nitrite) to improve the low temperature performance of mortar.
• Construction process: Preheat the mortar before construction and take insulation measures after construction.
• Effect: The fluidity of the mortar is significantly improved, the bonding force is enhanced, and the performance loss caused by low temperature is avoided.

Case 3: Optimization of tile adhesive in high humidity environment

• Formula adjustment: Select cellulose ether with low hygroscopicity (such as HPMC) and increase its dosage appropriately (such as 0.4%-0.6%). Add glue powder with strong water resistance (such as epoxy resin glue powder) to improve the water resistance of mortar.
• Construction process: Ensure that the base layer is dry before construction, and take ventilation measures after construction.
• Effect: The water resistance and adhesion of mortar are significantly improved, avoiding the performance degradation caused by high humidity.

Case 4: Optimization of tile adhesive in dry environment

• Formula adjustment: Select cellulose ether with good water retention (such as HPMC) and increase its dosage appropriately (such as 0.5%-1%). Add water reducer (such as calcium lignin sulfonate) to improve the fluidity of mortar.
• Construction process: Wet the base layer before construction, and increase the water content of mortar appropriately during construction.
• Effect: The water retention and construction operability of mortar are significantly improved, the adhesion is enhanced, and the construction quality is guaranteed.
