Xi'an Waterstop Glue for Construction
Product Introduction Waterstop Glue for Construction is a single-component elastic sealant that expands when exposed to water and cures when exposed to water. It is based on polyurethane prepolymer and contains urethane paste with special grafting technology. After curing and forming, it has a dual sealing and water-stopping mechanism of volume expansion when exposed to water and elastic sealing and water-stopping. This product is mainly suitable for the waterproofing of construction joints including deformation joints of post-cast belts and embedded components in industrial and civil construction underground engineering, municipal tunnel protection projects, mountain and underwater tunnels, underground railway sewage treatment tanks and other projects, as well as the water leakage control of existing projects. .
Two product features
Good water-stopping effect. It has the dual water-stopping mechanism of elastic water-stopping of rubber and self-volume expansion sealing after contact with water. It has maximum resistance to water pressure, strong durability and low mass change rate. Water-stopping for construction. The glue contains urethane linking chains with special grafting technology, which will not cause the loss of expansion elements during long-term use. At a temperature of ℃, the theoretical life is one year. It is a convenient single-component paste for construction. A standard caulking glue construction gun or putty knife can be used for caulking construction. It has good adhesion and can be firmly bonded to concrete and other foundation surfaces. It requires a low moisture content of the foundation surface and can bond firmly even when it is wet. Technology and environmental protection have good resistance. The chemical properties are resistant to chemical media such as hydrochloric acid, sea water, sodium carbonate, potassium hydroxide, etc. It can be directly used in drinking water projects. It is safe and non-toxic and is an environmentally friendly product. Good cost performance, performance is better than traditional construction joint waterproofing materials such as steel edge rubber waterstops or waterstop strips, and the price is moderate.
Three Application Scope
Structural joint sealing and pipe leakage blocking, such as rough or smooth structural joint sealing in concrete castings, joints between prefabricated parts, such as manholes, box-type underground trenches, cable trenches and pipes Joint sealing bolts around equal-shaped steel or gaps around pre-cast holes, etc., sealing of orthogonal pile walls, waterproof leakage sealing of underground tunnel projects, etc.
Four construction methods
Before construction, the dust and oil on the surface need to be cleaned, and there are no special requirements for whether it is smooth, dry, or wet.
Put the sealant into the glue extrusion gun, screw on the glue nozzle, and cut the size and width of the glue nozzle according to the joint requirements.
The glue gun squeezes the sealant into the construction joints.
Avoid contact with water until the sealant is applied.
Five packages
Or soft packaging or other packaging according to user requirements.
Storage in a dry environment below ℃, the storage period is months.
Six Precautions
Avoid direct construction on rainy days and in places that are in contact with water for a long time to avoid premature expansion of the glue.
Construction at the casting site should be carried out before pouring.
Care should be taken when pounding concrete to avoid damaging the sealing properties of the material.
