Whether it can be used after swelling in water
Many people will encounter some problems when using the water-swelling water-stop bar.For example, can the water-swelling water-stop bar still be used after rain, is it stable, the water stop bar will harden after rain, this is just a kind of Physical change, called swelling, is similar to dissolution. Dryness can be restored.
Product features of water-stop swelling strips (13785855258 Manager Fu)
This product has the effect of swelling under water, "stops water with water"; it has a slow expansion rate, its swelling rate ≤50% of swelling rate when immersed in 186h; this product is easy to install and construct, the price is low, and it is non-toxic and non-polluting. No dissolved matter precipitates under water immersion; compared with other hydrophilic swelling waterstops, its hydrophilic swelling has not been lost after long-term repeated swelling.
Application of Water-stop Swelling Water-stop Strip in Underground Engineering
Water-swellable water stop strip is a self-adhesive rubber strip that swells in water, and its expansion rate in water can reach 480%. Introduce the expansion performance of ordinary and slow-swelling water-swelling water-stop strips under different media conditions and the construction and construction of BW water-swelling water-stop strips in post-construction pouring belts, construction joints, pile heads and wall-through steel pipe waterproofing Precautions.
The water-swellable water stop strip is a self-adhesive adhesive strip that expands when exposed to water, and can be directly pasted on the surface of the concrete construction joint.After encountering water, the volume expansion will block the construction joint and the surrounding capillary holes to achieve reliable anti-seepage requirements; In the reinforced concrete, because of the stirrups or other steel bars at the construction joints, it is impossible to embed the metal water stop film and the rubber water stop film. The water stop bar is suitable for horizontal and vertical construction joints and post-pouring belts in basements, swimming pools, sewage tanks and concrete projects.It can also be used as expansion joint caulking for waterproofing, and as a contact between the steel pipe and the concrete wall through the wall. Leaky waterproof treatment. It has been widely used.
