Calculation method for water swelling and water-stopping glue usage
Treatment after water swelling and water-stopping glue:
If it takes a long time from the construction of the water stop glue to the next time the concrete is poured, please be careful not to protect the water stop glue from water. If the immersion does not cause water to swell and the waterstop is peeled off, it must be repaired before pouring concrete. The repair method is as follows: firstly fix the peeled water-stop glue with a nail to remove the accumulated water; then remove the peeled water-stop glue and re-construct.
Polyurethane sealant notes:
The distance between the water stop glue and the edge of the concrete shall not be less than 100mm. If the distance is too small, the expansion stress will cause the concrete to burst. If it is necessary to separately squeeze the water stop glue, the overlap length is not less than 20mm. The next time the concrete is poured, the vibrating bar cannot directly contact the water stop glue.
Water swelling, water-stopping gel, slow expansion
Its 7-day expansion rate accounts for ≤50% of the maximum expansion rate (measured value can reach 39.3%), which is very suitable for the construction environment with damp and multi-water; easy to construct single-component, gel-like, one-component water swelling Water-stop glue, can be used with standard caulking construction gun; construction adhesive can be firmly attached to the concrete surface, regardless of whether the base surface is wet, smooth or rough. Water-swellable water-stopping glue has good chemical resistance, and the construction joint meets water-expansion water-stopping glue, which can resist chemicals such as -, salt water, sodium carbonate and potassium hydroxide; it can be in contact with drinking water, safe and non-toxic, 606 Water-swellable water-stopping glue is an environmentally friendly product. *
One-component polyurethane sealant Advantages: "One-component" is mainly relative to "two-component". There is a two-component polyurethane sealant. When used, it is necessary to proportionate a and b components evenly. Mixing can achieve the effect of bonding and sealing; while the single component is used directly, it is convenient, simple and easy to construct. "Moist curing" means that the one-component polyurethane sealant is cured by a small amount of water vapor reaction in the air, and reacts with reactive groups on the surface of the substrate to bond. Compared with the conventional silicone glue, the polyurethane adhesive has a high elongation of more than 3 times and a bonding strength of more than 2 times.
The one-component polyurethane sealant produced by Hengshui Kangpu Technology Development Co., Ltd. is non-toxic after it is completely cured. It can be used in drinking water projects and has been tested by authoritative.
