How Should Carbon Fiber Cloth Be Applied On The Concrete Surface?

This material is often used on the surface of concrete. When using it, first make sure that there are no impurities on the surface of the concrete. If impurities are found on the surface of the concrete, all these impurities must be cleaned up, and the surface of the concrete should be polished first. , If there is a corner, it should be polished to a rounded corner, and the radius of the rounded corner should be about 20 mm. After cleaning the foundation surface, the next step is the process of construction work on the concrete surface.

The first process of using carbon fiber cloth on the concrete surface is to apply a layer of carbon fiber primer. This layer of carbon fiber primer is mainly for correcting some uneven places on the foundation surface. The next second step is to apply a layer of carbon fiber impregnating glue. When applying a layer of glue, it must be applied fully and evenly.

The third step is to cut the carbon fiber material. Of course, it needs to be cut according to the specific size when cutting. The cut carbon fiber material should be evenly and straightly spread on the concrete surface. Please pay attention to when laying carbon fiber. It needs to be spread more evenly. If the carbon fiber needs to be spliced after laying, the length of the overlap should be 20 cm. Then the fourth step is to continuously use a plastic scraper or use a rubber stick to repeatedly press on the surface of the carbon fiber material. Make the surface of the carbon fiber very straight and there should not be any bubbles inside. Make sure that the carbon fiber and the adhesive are sufficient. The penetration bonding together.

The fifth step is to apply a layer of epoxy resin dipping glue on the surface again. This time, the surface also needs to be covered to ensure that the surface is fully wetted. The sixth step is to use 3 to 6 mm of sand and stone to carry out the construction operation on the glued surface. After the operation is completed, paint a layer of coating and you are done.

There are many problems to pay attention to when carbon fiber cloth is applied to the concrete surface. For example, attention should be paid to the dryness and cleanliness of the construction surface. The construction temperature should also be properly controlled. Generally speaking, the construction temperature should be between 5°C and 40°C. It is better not to construct if it exceeds this temperature range. If it is rainy and open in the open air, it is not possible to construct. The humidity of the construction environment is better to be controlled at more than 85%. If the concrete surface is exposed in an outdoor environment, it is best not to construct. , Otherwise, the construction quality may be seriously degraded due to the weather.
