Cangzhou Shenlong pipeline professional steel surface treatment, for steel shot blasting, spray painting, pickling (steel structure corrosion and rust removal) and other processing methods have a very high level, whether it is steel plate, profile, or other steel structure parts, can be processed, including export steel project packaging, shot blasting spray painting. Heavy anti-corrosion pipe, cement pipe, buried pipe in waterworks, and other services, followed by shenlong to tell you about the type and design of anti-corrosion steel pipe

The quality of coating construction has a great influence on the performance of the coating. There are many examples in the actual painting process where the expected corrosion prevention effect is not achieved because of the improper construction method. In particular, much excellent performance of anti-corrosion coatings is extremely sensitive to the construction method, only in strict accordance with their respective construction conditions can be constructed to form a normal coating, to achieve the expected anti-corrosion protection.

1. the substrate must be strictly surface treatment

Iron and steel base material must be derusting, deoiling treatment, phosphating treatment can be determined according to the specific situation.

2. to ensure the necessary coating thickness

The thickness of the anticorrosive coating must exceed its critical thickness in order to play a protective role, which is generally 150μm to 200μm.

3. Control the temperature, humidity, and other environmental factors at the painting site

Indoor coating temperature should be controlled at 20℃ ~ 25℃; Relative humidity varies depending on the variety, generally, about 65% is appropriate. During outdoor construction, there should be no wind and sand, drizzle, temperature not less than 5℃, and relative humidity not higher than 85%. Frost, dew, rain, and falling sand should be avoided on incompletely cured coatings.

4. Control the coating interval

If the primer is placed too long after coating, it will be difficult to attach and affect the overall protective effect. In addition, must strengthen the construction personnel training and construction quality management. Requirements for the construction personnel to understand the nature of paint, usage, construction points, and technical requirements. The management should strengthen quality control to ensure that each process meets the technical requirements, so as to get a corrosion-resistant coating with excellent performance. Also, strengthen labor safety protection, pay attention to solvent volatilization, and strengthen ventilation, so as to avoid poisoning.
