——High toughness, high bonding characteristics, high strengthu0026nbsp;
Polymer anticorrosive mortar is a new type of concrete repair mortar with both the adhesiveness of polymer materials and the durability of inorganic materials; it has high compressive strength, rapid curing and good bonding performance;u0026nbsp;< span style='padding: 0px; margin: 0px; text-align: left; transition: all 0.2s linear 0s; font-family: 宋体;'>has good water retention and crack resistance, salt and alkali resistance Resistance, acid corrosion resistance, UV resistance; easy to operate, can be constructed on wet base, healthy and environmentally friendly. The construction steps become simple and convenient, the durability is synchronized with the concrete, the construction period is shortened, and the economy can be ensured. u0026nbsp;
一. Application range:
1, the concrete structure is damaged Repair of components, beams, slabs, columns, stairs, etc.;
2, building (structure) using high-strength stainless steel stranded wire mesh plastering and leveling protection mortar;
< /span>3. Repair of damaged concrete parts in roads and bridges;
4. Repair and repair of airport runways, highway lanes and damaged parts;
5. Repair and repair of damaged parts of concrete floor of industrial plant.
6. Anticorrosion of chemical plants and sewage ponds Layers of plastering and repairing. < br/>二. Typical use:u0026nbsp;
This product is mainly suitable for the repair of voids, honeycombs, breakages, spalling, exposed tendons and other surface damage parts of concrete structures to restore the good performance of concrete structures. It can also be used as carbon fiber reinforced leveling mortar, high-performance masonry mortar, and plastering leveling protective mortar for steel strand reinforcement in buildings (structures). The product is added with a variety of high molecular polymer modifiers, rubber powder and anti-cracking fibers. Therefore, it has good workability, adhesion, impermeability, peeling resistance, freeze-thaw resistance, carbonization resistance, crack resistance, steel rust resistance and high strength. u0026nbsp;
三. Construction features:
1. Convenient construction: available Good construction and easy performance. There is no need to vibrate during construction, just add water and stir on site;
2. Early strength, high strength: 8 hours compressive strength can reach 30Mpa, which can speed up the progress of the project to the greatest extent;
3. Good bonding performance: If the concrete interface treatment agent is used, it can ensure the tight adhesion between the high-strength concrete repair mortar and the repair base to the greatest extent< /span>u0026nbsp;

4. Strong durability: no significant change in strength after 50 freeze-thaw cycles , The strength will increase after 30 days of soaking in engine oil. < br/>Three.Product performance indicators u0026nbsp;
four. Construction method:u0026nbsp;
1. Basic level requirements and treatment: basic level The surface should be smooth, rough, clean, free of greasy dirt, no floating dust, sanding, hollowing, cracks, etc. Before construction, use high-pressure water to rinse and keep it in a damp state, but there should be no accumulation of water. When the interface is bonded, the interface treatment agent can be painted in advance. (See the instructions for the use of interface agents)
2 、Material preparation: Weigh and place the powder: water according to the mass ratio of 100:13-14. Pour 90% of the actual amount of water into the powder and stir evenly, then gradually pour the remaining 10% of water and stir without agglomeration. The prepared slurry should be used up within 30 minutes.
3. Construction: concrete base surface first Dilute water and interface agent 1:1 and mix evenly, brush on the concrete, and after it dries, apply another layer of interface agent (undiluted) evenly. The construction area of ??interface agent polymer anticorrosive mortar should not be too large at one time. The construction should be staggered by sections and blocks, and the area of ??each block should not be larger than 10 square meters, and the interval of staggered construction should not be less than 12 hours. In the layered construction, the positions of the remaining seams should be staggered.
4. Polymer anticorrosive mortar paving completed After that, it should be pressed and wiped immediately and smoothed once, and it is not advisable to repeatedly wipe the pressure. When there is air bubbles, it should be pierced and pressed tightly, and the surface should be dense. When the thickness of the facade or top surface layer is greater than 2.5 cm, the construction should be layered. The thickness of each layer should be about 1 cm, and the lower layer can be constructed when the previous layer is touched by the fingers. u0026nbsp;
??5. Initial maintenance:
The surface of the construction body can be cured by sprinkling water after initial setting. The level ground should also be covered with damp sacks and so on.5-40℃ Curing for at least 7 days.
