1. Rotate the lid of the bucket counterclockwise to open it, and use a mixer or other tools to re-stir the adhesive to avoid separation of the adhesive.
2. The mixing ratio of polymer mortar is KL binder: #sulfoaluminate cement: sand (use 18 mesh sieve bottom): =1:1.88:3.25 (weight ratio).
4. Weigh the cement and sand in a measuring bucket and pour them into the iron ash tank for mixing. After stirring evenly, add the binder according to the mix ratio and stir. Water can be added appropriately according to the workability.
By the standards of "Technical Regulations for Exterior Wall Insulation Engineering". in:
①Alkali-resistant tensile breaking strength
(longitude, latitude) ≥ N/, tested according to Appendix A.12 in -, 20 pieces each in the warp and weft directions.
Sample size: ×, soak in (23±2)℃, 5% NaOH aqueous solution, take out and soak in tap water for 5 minutes, then float in running water for 5 minutes, then bake in (60±5)℃ oven for 1 hour, store for later use;
②Alkali-resistant tensile fracture strength retention rate
(≥50% in warp and weft direction, rapid method, use NaOH, KOH, and Ca(OH)2 mixed alkali solution and soak at 80 ℃ for 6 hours.
