Cement-based penetrating crystalline waterproof coating
Self-repairing and permeable, permanent waterproofing construction is simple, non-toxic and harmless
1. Product introduction
Cement-based penetrating crystalline waterproofing material is imported from abroad Imported active chemical products, commonly known as masterbatch, are combined with gray powdery inorganic materials composed of ordinary cement, silica sand, etc. Its waterproofing principle is: the unique chemical properties of this material utilize the chemical properties and porosity of cement concrete itself, Using water as a carrier, with the help of osmosis, it communicates with the micropores and capillaries of concrete, filling and catalyzing the hydration of particles and incompletely hydrated components in the concrete to form insoluble dendritic crystals and combine with the concrete to form a whole. , thus causing water and other liquids coming from any direction to be blocked. It can achieve the effect of permanent waterproofing, moisture-proofing and protecting steel bars to enhance the strength of concrete structures.
2. Product features
, self-healing ability. There is a unique catalytic effect that activates to produce new crystals when exposed to water. Therefore, when water penetrates into tiny cracks in the concrete structure after a few years, new crystals will be produced to block the water. This self-healing ability is unique
, Enhance the strength of concrete, resist chemical corrosion, and protect steel bars
, Non-toxic, non-polluting, safe and environmentally friendly, can be used for domestic water concrete structures
, The construction base surface is not as required as a general waterproof layer Smooth and dry. On the contrary, the base surface is required to be rough and wet for better use
. The construction method is simple and the construction cost is low. After the coating is solidified, it is not afraid of collision and is resistant to puncture and tearing, so the steel bars installed in the backfill do not need protection. layer to reduce the project cost
. The surface can be coated with cement mortar, lime paste, epoxy resin and other coatings, and the bonding effect is good.
3. Scope of application
Waterproofing construction of concrete structure base, blocking construction of structural cracks, seepage points and holes, waterproofing and plugging of subway stations, underground diaphragm walls, tunnels, bridges, reservoirs and sewage treatment tanks Leak construction, waterproofing and plugging of basements, bathrooms and pools in industrial and civil buildings.

5. Construction requirements
Clean the base surface, the base surface should be rough and clean. Spray water to wet the base surface, but there should be no open water. Mix Bolon cement-based penetrating crystalline waterproof coating: water = (weight ratio) evenly, and use a nylon brush to evenly brush the mixed glue on the waterproof base surface. , generally apply twice, the material used per square meter is ~. (thickness is.)
. The interval between applications should be within hours. It is better to apply the second coat when the initial setting of the first coat is still moist. If it is too dry, spray water first to moisten it. The mixed glue should be used up within minutes. When the material becomes thicker, no water can be added. It can only be stirred frequently. The brushing should be even, and there should be no white background or deposits on the convex and concave areas
After the coating is semi-dry, start spraying with mist water for maintenance, ~ times a day, for ~ days to prevent premature drying of the coating
Commonly used construction methods for coatings include: brushing method, dry spraying method , spraying method, etc.
6. Precautions
In open-air construction in hot weather, it is recommended to carry out construction in the morning and evening to prevent the coating from drying out prematurely and affecting penetration. If cement-based materials are used on the coating surface to continue construction, it should be carried out after an hour, such as backfilling soil. , do not backfill with dry soil within days to prevent it from absorbing water into the coating. During the maintenance period of 1 hour, prevent rain, frost, exposure to the sun and low temperatures below 10 degrees Celsius. It is better to cover with moisture bags for open-air construction, but avoid water accumulation. When protecting with plastic film, it must be set up to ensure the breathing and ventilation of the coating.
