In order to enhance the performance of mining I beam production plant and extend its service life, it is necessary to carry out anti-corrosion treatment for it. The effect of anti-corrosion will have a great impact on the use of section steel, so pay attention to the following points in the process of coating the anti-corrosion layer:
First, ensure the quality of coating
This point is very important, if the quality is not up to the standard may cause anti-rust, crack and other problems,mining I beam production plant quality is therefore decreased.
Two, there are substandard operations in the process of brushing
1, brushing is not a one-time completion, it will often be divided into primer and finish two processes, if the details of which are mistaken will produce quality hidden trouble.
The BESMEAR OF PRIMER AND FACE PAINT BRUSHES PASS NUMBER AND THICKNESS HAVE CORRESPONDING REGULATION, WANT TO PRESS STANDARD FORM IN THE CONSTRUCTION PROCESS. By comparison, the number of passes is less specified than specified.
Some steel structure manufacturers in order to save costs will do this thing: in the calculation of the construction budget to the standard number of brushing and thickness, but in the actual construction process but reduce the application of materials. While this does achieve cost savings, it also degrades the performance of the coating and renders the setup useless.
2. The process is chaotic
At present, there is no unified painting process, some will be in the first primer and finish paint painting, in the completion of the construction in the lifting, transportation. Although this method is relatively easy, but the subsequent operation will be the varnish inevitably destroyed, can only be repaired at the installation site. The finished coat will not be exactly the same in quality or tone as the original. Although the original intention is to save trouble, but at the same time wasted costs and man-hours, the gain is not worth it.
