Carbon fiber epoxy resin adhesive use method

Construction points

1. Clean the concrete surface with acetone.

2, the surface to be bonded to repair the formation of a leak, the phenomenon of water to stop, guide water treatment.

3. When the bottom layer is glued and coated, the thickness of the coating shall be determined according to the specific conditions of the air temperature and the construction bonding structure, especially if the winter temperature is below 5°C. If necessary, the necessary temperature raising measures shall be taken.

4, when bonding carbon fiber sheet, first cut the required size according to technical requirements, generally two meters is appropriate.

5, configuration glue, generally available time (about 30min) the amount required for construction is limited.

6. Put the glue of Group A and Group B into a clean container according to the ratio of Group A: Group B = 3:1, mix well, and use a smooth roller to repeatedly roll on the surface of the carbon fiber cloth to the glue in the same direction. Exudate the surface of the fiber cloth to remove air bubbles so that the carbon fiber cloth can fully infiltrate the glue. The overlap area of ​​the carbon fiber sheet must be set 10 cm or more.

7. Multi-layer sticking should be performed on the surface of the upper carbon fiber cloth after the touch is dry, and then paste the next layer of carbon fiber cloth.

8. When it is cured, it should be protected from rain, wind and sand, and prevent hard objects from scratching the bonding surface.

9. The curing time should not be less than 3-7 days. After curing, the surface coating shall be performed according to the requirements.

10, B component prone to discoloration during the long storage process, is normal, does not affect the basic performance and use of the product.

11. In the course of construction, if you accidentally splash on the skin or in your eyes, rinse with plenty of water immediately. In severe cases, you should seek medical advice promptly.

Features

1. Polymer nanomaterial modified epoxy resin, superior performance;

2, anti-impact and hot and humid aging, fully meet the national standard;

3, the site is easy to use, the amount of savings, and fiber cloth fit;

4, green, non-toxic, safe to use.

what makes most electric power tools "different" from one another depends on how the physical energy is used, or its application. The process of making physical energy with electrical energy is very similar and where most performance issues occur. for most power tools, and happens to be where most maintenance is required

Although there is a lot more to be said about how electric motors work, no one has to be an electrical engineer to understand a motor's basic parts. And understanding what goes on inside of a power tool makes diagnosing problems easier.

If the problem can be pinned down early, then the tool is just a part and a quick repair away from being almost like new again. Even some of the repairs and maintenance required for electric power tools are fast and easy to do.
