Product introduction of a non-toxic cement-based penetrating crystalline waterproof coating. This product uses ordinary Portland cement, also known as Portland cement abroad, quartz sand and other inorganic materials as the base material, and is infiltrated with active compounds and various other auxiliary materials. Made of a light gray powdery waterproof material. It is a green, non-toxic, odorless and pollution-free product. It is a rigid waterproof material and its quality meets national standards.
The waterproofing mechanism of the product is that after the active compounds contained in the material interact with water, they use water as a carrier to penetrate into the pores of the internal structure of the concrete. The active compounds that penetrate into the pores inside the concrete interact with the free calcium oxide in the concrete. The interactive reaction produces calcium sulfoaluminate, a dendritic fiber crystal that is insoluble in water. The crystals absorb water and expand in the structural pores, from sparse to dense, gradually forming a dense impermeable area on the surface of the concrete structure in depth, greatly improving the impermeability of the overall structure. In the waterproof coating constructed with type waterproof coating, due to the hydration space and the binding of the gel, a large number of gel-like crystals are formed, which play a dense and impermeable role in the coating. As time progresses, the amount of crystallization increases. It is also increasing. The gel crystals in the waterproof coating and the penetrating crystals deep into the concrete structure both increase the density of the concrete structure, that is, enhance the impermeability of the concrete structure. Since the hydration reaction of cement is an incomplete reaction process, the reaction will still proceed many years later without losing water. In the later hydration reaction process, the active compound can also continue to be catalyzed to form crystals. Therefore, Even if the concrete structure is penetrated again by water or is partially damaged with cracks and cracks smaller than 10%, it can repair and heal itself under the action of crystallization. It has the ability to resist penetration for many times, which essentially improves the instability caused by the volume of ordinary concrete structures. Split again.
Performance characteristics of two non-toxic cement-based penetrating crystalline waterproof coatings
It has dual waterproofing properties. The penetrating crystals it produces can penetrate deep into the concrete structure and block the structural pores, regardless of its penetration depth. They can all play a waterproof role inside the structure. At the same time, the coating that acts on the base surface of the concrete structure can compensate for shrinkage due to its micro-expansion performance, making the structural base surface after construction also have good crack resistance. Anti-penetration effect.
It has extremely strong water pressure resistance. It can withstand strong water pressure for a long time. Apply two layers of this material on thick concrete specimens with compressive strength of 100%, which can at least withstand water pressure.
Has unique self-healing ability. This product is an inorganic waterproof material. The crystals formed will not age. The crystal structure can still activate cement to produce new crystals when exposed to water many years later. The crystals will continue to be densely sealed or re-sealed. Smaller than cracks or pores, completing the self-healing process.
It has the function of anti-corrosion and anti-aging protective steel bars, which can self-repair cracks and gaps under the penetrating crystallization, making the concrete structure more dense and increasing the structural strength, thereby minimizing the intrusion of chemical substances, ions and moisture, and protecting Steel bars are protected from rust. Crystals do not affect the breathing ability of concrete, and can maintain normal ventilation, moisture removal, and dryness inside the concrete. On the basis of keeping the inside of the concrete structure from being corroded, it extends the service life of the building. At the same time, the concrete structure treated with this material also effectively prevents spalling, weathering and damage caused by freezing and thawing.
It has a reinforcing effect on the concrete structure. After the concrete structure is constructed with this product, the unhydrated cement is activated and the density is enhanced, which strengthens the concrete structure and generally improves the strength of the concrete.
It has a long-term waterproofing effect. The physical and chemical reaction it produces is initially on the surface of the base surface or adjacent parts, and gradually affects the interior of the structure and penetrates over time. Under normal temperatures, usually after 10 days, the active compound can make the penetrating crystals penetrate deep into the concrete layer structure. The density of the concrete layer structure is sparse, and the penetration depth will be deeper. The formed crystals have stable properties and do not decompose. Even if the waterproof coating is worn or scraped off, the waterproofing effect will not be affected because its active ingredients have penetrated deeply into the concrete structure.
It has the advantages of simple construction method, saving labor and time. This product is simple and convenient to construct. It can be constructed by brushing, rolling or scraping, or it can be constructed by dry spreading. Under normal conditions, the construction task can be completed in one application without the need for multiple applications, saving time and labor.
Comply with environmental protection standards, non-toxic, non-polluting, non-pollution. The active compounds in this product are water-soluble compounds, which are non-irritating to human skin and non-toxic. They can be used in drinking, food, swimming pools, reservoirs and other engineering construction projects.
Applicable scope of three non-toxic cement-based penetrating crystalline waterproof coatings
This product can be widely used in tunnels, dams, reservoirs, power stations, nuclear power stations, cooling towers, underground railways, overpasses, bridges, underground diaphragm walls, airport runways, pile heads and foundation wastewater treatment Waterproof construction of pools, water plants, industrial and civil buildings, basements, roofs, toilets and bathrooms, etc., as well as repair and plugging of all concrete structural defects such as concrete building facilities.
Four non-toxic cement-based penetrating crystalline waterproof coating construction methods
The materials are mixed into cement mortar according to the water-cement weight ratio for painting construction. The general dosage is/㎡ thickness in special parts or according to the design The required dosage is/㎡. The paint should be stirred fully and evenly without any small gray balls. Mix as much as you use. The stirred paint should be used up within minutes. Under high temperature conditions, the time should be shorter accordingly.
The common construction methods of coatings include brushing, roller brushing, scraper, mud clipping, spraying, etc. Dry powder spreading method can also be used. The construction by brushing and roller methods should be completed in two times. The time interval between two coatings should be 0.1, and the painting should be done back and forth in forward and reverse directions. Other construction methods can be completed in one time.
Cavities, gaps, honeycombs and other phenomena on the surface of the concrete structure must be repaired. In particular, mortar drippings must be removed. Mud floating blocks, oil stains and other sundries on the base surface must be removed before construction can be carried out. During the painting construction It is necessary to keep the base surface fully moist before painting. Sometimes it is necessary to spray while painting to keep the base surface moist.
This product itself has a unique moisturizing effect. Generally, it is required to spray water for moisturizing and maintenance within hours after construction, once a day, and then again every other day for maintenance and moisturizing. Water storage cannot be used for maintenance.
