I. Performance and use
This product is a new patented product developed and produced by high-tech nanotechnology, with strong penetration and excellent waterproof effect. It is a kind of permeable crystallization, efficient and rigid building waterproof product. This product is a water-based white emulsion, nontoxic and odorless, with PH value 12, density 1. 18 ~ 1.2 and solid content ≥ 20%. It is sprayed on the surface of dry porous inorganic building materials such as brick, cement, stone, gypsum, lime, fangci paint, asbestos products, perlite and insulation board. Very active nano-silicon particles penetrate into the interior of building materials, cross-linking to form a solid network crystal structure, blocking pores and forming a colorless permanent waterproof layer; At the same time, silane-based components are consolidated on the surface of building materials to produce strong hydrophobic molecules, which have excellent waterproof and impermeability. It can effectively prevent buildings from weathering and frost cracking, and has the functions of cleaning, anti-fouling, anti-mildew and anti-moss. This product is directly mixed with cement mortar or concrete, and is used for self-waterproofing projects of rigid structures such as pools, dams, culverts, toilets, bathrooms and basements. Its unique waterproof effect can be seen. This product has reliable quality, good durability, acid and alkali resistance, excellent weather resistance, no corrosion to steel bars, safe use, convenient construction and low cost. It is one of the ideal waterproof materials in building engineering. Its impermeability in mortar is ≥S 14 and in concrete is ≥S 18. The technical indicators meet the standards of JC 474- 1999[ Waterproofing agent for mortar concrete] and JC/T902-2002[ Permeable crystallization waterproofing agent].
Second, the method of use
1, brush and spray construction:
Before use, clean the base surface (especially oil stains and moss), add 8 times of clear water to the nano-silicon waterproof agent, stir it evenly, and apply it directly to the dry base surface with a sprayer or brush. After dilution per kilogram, it can be applied for about 40~50m2 each time, and it can be applied continuously at least twice in vertical and horizontal directions (when it is wet for the second time). For the rough surface of 1: 2.5 mortar, it can be brushed twice or so. No rain or water immersion is allowed within 24 hours after construction, and construction should be stopped below 5℃. After drying at room temperature, the waterproof effect is excellent, and the effect is even better after one week (curing time is longer in winter). The test shows that the waterproof effect of the cured waterproof block has no obvious change after repeated heating at 200℃ and repeated freezing at-18℃ for 20 times. Diluent is available now, and it was used up that day.
2, waterproof mortar construction:
Clean up deposits, sundries, oil stains, etc. Base course, the ratio of lime to sand shall be controlled at 1: 2.5 ~ 3 (the silt content is 32.5r, and the portland cement and medium sand are less than 3%); Adding 8- 15 times (volume ratio) of water into nano-silicon waterproof agent stock solution can be directly used to prepare waterproof mortar, with water cement ratio ≤0.5, and the actual net waterproof agent consumption accounts for 3-5% of cement. The waterproof layer is constructed in two layers (each layer is 10mm thick); The bottom layer shall be plastered with 1mm plain mortar first, then with waterproof mortar layer, compacted during initial setting, and poked into pits with a wooden trowel; Apply the second layer of waterproof mortar, and then press it out for compaction. According to normal curing, it is better to spray cement curing agent.
3, waterproof concrete construction:
Nano-silicon waterproof agent can be directly prepared into concrete by adding 45 times of water (volume ratio), and the actual net waterproof agent consumption accounts for 1% of cement. The construction method is the same as ordinary concrete. After construction, it is best to maintain normally and spray cement curing agent.
4, leakage maintenance construction:
The original base was smooth and needed to be chiseled into a pit. After the floating ash is cleaned, the cement slurry is applied to increase the cohesive force of the old and new layers, and then the waterproof mortar layer is applied. In the leaking part, nano-silicon instant plugging agent must be used for plugging and stopping water. Yin and Yang angles should be rounded and compacted. The stubble should be sloping (the stubble width is 100~ 150mm), and the stubble should be brushed with cement slurry first and then with waterproof mortar layer.
Third, matters needing attention
1, this agent can't be sprayed outdoors below 5℃ in winter. As an additive in winter construction, it can be used in conjunction with sodium nitrite antifreeze.
This medicine is a common chemical. During storage, transportation and use, construction personnel should be careful not to splash on their faces, especially in their eyes. Otherwise, immediately rinse with plenty of water or seek medical treatment. Wear latex gloves, protective glasses and work clothes during operation to avoid contact with skin.
3. This reagent shall not contact with active metals such as zinc, aluminum and tin. During transportation and use, it shall not be stored in iron metal containers to avoid product deterioration and container corrosion caused by chemical reaction.
Four. Storage, transportation and shelf life:
In the process of storage and transportation, prevent rain, exposure and damage to packaging containers; The storage and transportation environment temperature is 0 ~ 25℃.
