一. Scope of application
·Use fast when there are honeycombs, loopholes, cracks, and protective layer damage on concrete surfaces such as harbors, wharfs, roads and bridges, building structures, etc. Surface repair material for repairing protection;
·Structural reinforcement works for the repair and smoothing of reinforced concrete base;u0026nbsp;
·Thickening protective layer, smoothing of uneven surface, repairing of old concrete surface, etc.;
·Improve the durability of concrete and extend the life of concrete;
二. Features :
·Quick surface repair compound is composed of two components of emulsion and inorganic powder, which has the adhesiveness of polymer materials and the durability of inorganic materials The new type of concrete repair material; high compressive strength, fast curing, good bonding performance; good water retention and crack resistance, high alkali resistance, ultraviolet resistance; easy operation, wet base construction, 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. < br/>·Good impermeability, crack resistance, aging resistance, acid and alkali resistance And resistance to seawater erosion;
·Good adhesion to various materials; < br/>·Durability is synchronized with concrete. The fast surface repair compound is composed of two components of emulsion and inorganic powder. It is a new type with both the adhesiveness of polymer materials and the durability of inorganic materials. Concrete repair material; high compressive strength, fast curing, good bonding performance;
·Yes Good water retention and crack resistance, high alkali resistance, UV resistance, seawater corrosion resistance;
·Easy to operate, can be constructed under wet base conditions, the material is purely environmentally friendly. < br/>
三. Performance index of fast surface repair material:
four. How to use:
1 .Basic requirements and processing:
The base surface should be flat, rough, clean, No oil pollution, no floating ash, no 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 fast surface repair material interface treatment agent can be applied in advance.
2. Material preparation:
Powder: Emulsion (or water) according to the mass ratio of 5:1, weigh and place. Pour 90% of the actual amount of emulsion into the powder and stir evenly, then gradually pour the remaining 10% emulsion (or water) and stir without agglomeration. The prepared slurry should be used up within 0.5-1 hour . < br/>3. Construction:
in Paint the wet concrete base surface evenly.u0026nbsp;Interface treatment agent Oru0026nbsp;polymer mortar primer (powder : Emulsion is based on weight ratio3:1) While applying the interface agent, the polymer mortar is applied at the same time. The construction area of ??fast surface repair material should not be too large at one time, and the construction should be staggered in sections and blocks, and the area of ??each block should not be larger than 10 square meters, and the staggered construction interval should not be less than 24 hours. In the layered construction, the positions of the remaining seams should be staggered. < br/>After the quick surface repair material is spread, it should be pressed and wiped immediately and smoothed at one time. It is not suitable to repeatedly wipe and press. 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 10mm, the construction should be layered. The thickness of each layer of plaster should be 5-10mm, and the lower layer can be constructed when the previous layer's fingers are dry. < br/>Five. Note:
·Construction acceptance shall be carried out in accordance with the 'Technical Regulations for Anti-corrosion Engineering of Polymer Cement Mortar', 'Quality Inspection and Evaluation Standards for Construction Anti-corrosion Engineering' and 'Code for Construction Acceptance of Reinforced Concrete Engineering' (GB50204) D. < br/>六. Packaging and storage:
·Packaging: Powder50kg/bag, emulsion 20kg/bucket, in a ventilated and dry place above 5℃ and prevent direct sunlight; prevent freezing in winter. < br/>·The shelf life is six months.
