With the rapid development of the construction industry, more and more cable bridges are used in the project. Consumers like and love their performance and love. Because of more and more use, the requirements for equipment are also rising, so sometimes we need to use equipment coated with anti-corrosion coating, corrosion equipment and work, but what problems should be paid attention to in the selection of anti-corrosion coating? Let's take a look.
Special attention should be paid to the anticorrosive materials of Shandong cable tray under different working conditions.
1. Material characteristics of coating surface.
2. Application environment of painting object. There is a strong correlation between anticorrosive coating and environment. According to the specific application environment, such as medium type, concentration, temperature, equipment operation and other factors, select the appropriate type and model of anti-corrosion coating.
3. Construction conditions of anticorrosive coating. According to the actual situation of the cable bridge construction site, select the appropriate anticorrosive coating varieties, and select different anticorrosive coating and alloy structure under the construction conditions of embroidery construction, underwater construction, cement base construction, plastic base construction, anticorrosive coating, etc.
4. Comprehensive effect of technology and economy. Material cost, surface treatment cost, construction cost, coating performance, service life, maintenance cost, etc.
The construction quality of anticorrosive coating has a great influence on the performance of coating. In the actual coating process, due to the improper construction method, the expected anti-corrosion effect cannot be achieved. In particular, many excellent anticorrosive coatings are very sensitive to the construction method. Only in strict accordance with their own construction conditions, can form a normal coating to achieve the desired anti-corrosion protection effect. The base material shall be strictly surface treated. Derusting, degreasing and phosphating treatment can be determined according to the specific situation.
防腐施工时，应保证防腐层的必要厚度。防腐层的厚度必须超过其临界厚度才能起到保护作用，一般为150 m~200 m。控制喷涂现场的温度、湿度等环境因素。室内涂装温度控制在20℃~25℃;
The necessary thickness of anti-corrosion coating shall be ensured during anti-corrosion construction. The thickness of the anti-corrosion coating must exceed its critical thickness to play a protective role, generally 150 m ~ 200 m. Control the temperature, humidity and other environmental factors at the spraying site. The indoor coating temperature is controlled at 20 ℃ ~ 25 ℃;
For example, the application temperature of high-temperature anticorrosive coating must be greater than 10 ℃, and the relative humidity changes with the variety, generally around 65%. During outdoor construction, there shall be no wind, sand or rain. The temperature shall not be lower than 5 ℃ and the relative humidity shall not be higher than 85%. The uncured coating shall be free from frost, dew, rain and dust. Control the spray distance. If the time before finishing coat is too long, it will be difficult to adhere and affect the overall protection effect.
The above is to share with you today about the selection of anticorrosive coating for cable tray in Shandong Province. We need to pay attention to four aspects of relevant content.
