In China, infrastructure projects are in full swing, and various types of bridges, tunnels and roads are constantly being built on the land of China. At present, reinforcement has become the focus of construction projects. At present, the most popular reinforcement methods in China are the bonded steel method, the enlarged section method and the 300g carbon fiber cloth reinforcement method.
300g carbon fiber cloth reinforcement has unique characteristics. For example, its own material characteristics are resistant to acid and alkali and corrosion. It has light weight and high strength. So what should be paid attention to in the 300g carbon fiber cloth reinforcement method? Today, our reinforcement engineer will answer your questions.
1, temperature
First of all, the reinforcement of 300g carbon fiber cloth should be carried out under the ambient temperature of 5 °C and above, and should meet the construction temperature of the supporting resin. When the ambient temperature is lower than 5 °C, use a matching resin suitable for low temperature or use heat treatment measures. There is a special low temperature primer in Mankate.
2, the ratio
Next, when 300g carbon fiber cloth reinforced resin is prepared, it should be placed in the container according to the proportion specified in the product use instructions, and evenly stirred with a stirrer until the color is uniform. There should be no oil or impurities in the container used for mixing. It is advisable to determine the amount of each mixing of the resin according to the actual temperature of the site and strictly control the use time. For example, the Mankate primer A component and the B component are mixed in a ratio of 2:1, and when it is mixed evenly it can be used. The mixed glue should be used within 20 minutes (depending on the specific ambient temperature). The product has a density of about 1.10 to 1.15 g/cm 3 (cured product), and the initial gel time is about 1 to 6 hours.
In addition, there are many special precautions for 300g carbon fiber reinforced according to different reinforcement conditions. You can consult Mankate's reinforcement specialists for professional guidance.
