Butyl rubber waterstop material has good air tightness, good bonding strength, strong self-adhesiveness and deformability. It can be directly bonded to newly poured concrete without adhesives under certain conditions. It overcomes the leakage problem of ring pouring caused by the weak bonding between the water-stop material and the concrete interface in the past. It has good water resistance, acid and alkali resistance and aging resistance, and can be widely used in water conservancy and hydropower projects and various industrial and civil buildings. project. Products of different specifications can be produced according to user and design requirements. Instructions for use
When using this product, products with corresponding specifications should be used according to design requirements and construction needs.
After the previous section of concrete pouring process is completed, hardened and dried, clean it up, stick this product directly on the construction joint interface, and start the next section of construction.
Due to construction needs, a shallow positioning groove can be left in advance. After the construction surface in direct contact with the product has hardened and dried, it should be cleaned and then embedded in the reserved groove and pressed tightly.
When a joint is needed, it can be flattened sideways and overlapped to press water above it.
The construction surface should be solid, dry, without traces of oil, floating soil, or accumulated water. Pay attention to fire and rain protection during use or transportation. If it is accidentally exposed to rain, you can continue to use it after it is dry and the effect will not be reduced.
. It is not suitable for construction in rainy days. Due to the cold weather, artificial heating methods can be used. The construction temperature should be above ℃. If conditions permit, paving can be used to increase the temperature for better effect. If there are special circumstances, it can be solved through negotiation with the design department and construction unit.
