Concrete anti-carbonation coating is self-produced and sold with favorable price and quality assurance

Manufacturer's phone number Cui Xiaofeng
Concrete anti-carbonation coating is a cement-based polymer composite modified by a high-performance anti-carbonation emulsion. The emulsion contains unique copolymer components, which cause cross-reaction chains in the cement to form polymer cement water. The mutual transfer network structure of chemicals produces chemical and mechanical cohesion and adhesion, improves tensile strength and bonding strength, and is coated on the concrete surface and firmly bonded to form a high-strength, tough and durable elastic coating protective layer. It can effectively prevent carbon dioxide, chloride, oxygen, seawater, acid rain and other corrosive media from corroding structural materials in the environment. The coating is composed of high-performance polymer emulsion, a variety of additives (liquid materials, components) and modified cement-based materials (powder materials, components). After curing, the coating becomes an existing polymer material It is a new type of protective sealing material that has the flexibility and high durability of inorganic materials.
2. Purpose Manufacturer’s phone number Cui Xiaofeng
It is widely used in the anti-carbonization, anti-seepage, waterproofing and anti-corrosion of reinforced concrete structures such as water conservancy and hydropower, ports, tunnels, bridges and other industrial and civil buildings to improve the use of the structure. life. Such as cooling towers, aqueducts, sluices, dams, bridges, reservoirs, sewage treatment tanks, concrete poles and other projects.
3. Features
Good bonding strength and bonding ability, can be painted on the surface of a variety of building materials
Resistant to atmospheric erosion, ultraviolet radiation, and abrasion resistance, under normal use conditions , the service life can be more than 10 years
Excellent flexibility can not only seal the further expansion of fine cracks, but also resist the occurrence of new cracks caused by the expansion and contraction of the concrete matrix, and prevent moisture from entering the interior of the concrete< br/> It has good waterproofing and sealing properties to prevent external rainwater from eroding the structure
It has good resistance to the penetration of harmful gases, such as carbon dioxide, oxygen, salt spray, etc., preventing the neutralization of concrete, and it is also resistant to light Chemical corrosion, prevents chloride ions and acids, alkalis, and salt substances from penetrating into the concrete, and prevents steel bars from rusting
It is a water-based coating, non-toxic, odorless, and non-polluting.
A variety of colors are available upon request, with dark gray, off-white, beige and light blue as standard colors.
4. Construction methods
Base surface treatment
The concrete base surface should be hard, flat, rough, clean and moist. The convex, concave and uneven areas on the base surface should be ground and smoothed first with an angle grinder. Dust, laitance, oil stains, etc. on the base surface should be removed with a wire brush. Loose and hollow areas should be chiseled out. Larger defects should be removed using the polymer formulated with this product. For mortar repair and leveling, use the polymer putty formulated with this product to level various gaps, cracks or uneven places such as honeycombs and pitted surfaces. Before applying the anti-carbonation coating, the concrete base surface should be sprayed with water, cleaned and moistened in advance, and should be allowed to dry for a while before applying the coating when there is no feeling of moisture.
After bonding the carbon fiber cloth to the surface according to the normal process, a layer of clean quartz sand (quartz sand ~ mesh should be evenly dotted on the surface after the last coat of glue is applied, the dot should be thin Evenly and flatten it with a roller, and apply the paint after the surface is completely dry. For the transition area between the pasted carbon cloth and the concrete base surface, polymer putty should be used to level it and make a smooth transition.
Follow the normal process for bonding the steel surface. After the steel bonding construction is completed, remove the grease, dirt, rust and other attachments on the steel surface, and then apply epoxy iron red anti-rust paint. When the anti-rust paint is still wet, apply a layer of clean quartz sand evenly on the surface. And use a roller to flatten it, and apply the paint after the surface is completely dry.
Putty leveling If the base surface is uneven and has deep texture, the coating cannot cover it or the surface decoration function of the coating is high, flexible water-resistant putty can be used Scrape the base surface as a whole, and then apply anti-carbonation paint to achieve a better aesthetic effect.
Paint mixing
Before each paint preparation, the liquid components should be stirred evenly . The mass ratio of the paint is the component water (~. When painting the bottom layer, the amount of water added can be the higher limit. The ratio of liquid material to powder material should be accurately measured, and the stirrer should be used to fully stir evenly. The stirring time is about The mixed paint should be uniform in color and free of powder and sediment. The paint should be mixed and allowed to stand before painting.
Paint application
The coating should be painted in layers and in multiple passes. The base surface is not When scraping the putty layer, the paint should be applied ~~ times to form ~~ degree of coating. When there is a putty layer, just apply ~~ times to form a layer with a thickness of approximately 100%. The subsequent application must wait until the previous coating is dry. It can only be carried out after it is sticky to the hands (it is recommended that even in the quick-drying season of summer, the interval should not be lower than . The coating tool can be a brush or a velvet roller. When applying the roller, it should be rolled back and forth several times to ensure that no bubbles are left between the paint and the base layer and the bond is firm. The direction of the coating should be changed alternately for each coat. .If there is precipitation in the coating during use, please pay attention to stir it evenly at any time.
Coating maintenance
It is not suitable to be exposed to rain after the last coating is applied. If the coating is to come into contact with running water, it needs to be naturally dried and cured. Yes. When constructing in a closed humid environment, ventilation and moisture removal should be strengthened
