Cement-based permeable Crystallization type waterproof coating
Cement-based permeable crystallization type waterproof coating is cement gray powder materials doped with active chemical components prepared. Cement based permeable crystallization type series of waterproof coating, waterproof mechanism of it is the use of porous, under the action of water, waterproof coating containing active chemical substances, taking water as the carrier, with the infiltration of water on the structure of the pores of the active chemical substances, as the water penetrated into the interior, and the reaction of ettringite and other insoluble crystal, hydration reaction of the reactive chemicals and unhydrated cement particles occurs, and promote the formation of hydration of cement, cement hydration crystals, generating a large number of crystal filling, plugging the pores, so that water can not enter the concrete, so as to achieve the purpose of waterproof.
It is times of solid cement based permeable crystallization type waterproof coating series because of good adhesion, both the light base and the hair surface, the back surface of the water and the water face, dry and wet base base, or water base will not affect its construction effect.
Application range
Widely used in track tunnel, dam, reservoir, power station, nuclear power plant, cooling tower, subway, overpass, bridge, airport, underground continuous wall, waterproof construction of pile foundation, pile head wastewater treatment pond, reservoir, industrial and civil building roofing, basement, toilet, and concrete building facilities and all concrete structure repair the ills of plugging.
Product features
1. Permeability super ability, can with the passage of time gradually penetrated into concrete. Penetration depth of 30 cm.
2. Excellent anti permeability performance, can resist 120 meters above the water head pressure.
3. With waterproof function for a long time, the collision can bear external force without affecting its waterproof function.
4. Non-toxic harmless, green environmental protection, the application can be safe in the drinking water and food industry for concrete engineering.
5. The unique ability to repair itself, not the formation of crystal aging, even many years later for less than 0.4 mm in cracks and holes in the water can still produce crystal closed.
6. The coating can be directly accept paint, epoxy resin, cement mortar, lime paste, mortar.
7. The construction method is simple, easy to operate.

Construction
1. Scraping method
Cleaning waterproofing coating base surface debris and floating mud mortar, concrete base for serious uneven repair.
The eradication of oil on the water cleaning, anti cement concrete structure of debris, and then wash with water, construction brushing waterproof material in wet surface.
If there are serious leakage detected, should first by plugging materials of construction, and then use the material, to ensure the engineering quality.
The water cement ratio is 0.3-0.4:1, the dosage in 1.4-1.7kg/m2, the thickness of 1.0mm (+ 0.05mm) as the standard.
Roller coating method
Will the material by 1.4-1.7kg/m2 with the amount of uniform rolling brush roll on the surface treatment after the.
Stem spreading method
Construction immediately in the concrete pouring of dense compacted flat after. The required amount evenly spread on the surface of the concrete, timely wipe compaction. Check after the final set is there bad construction and timely repair;
In the exposure scenario, shall sprinkle maintenance. Pay attention to spray evenly, not cut corners.
