Compared with other building structures, large-scale space frame steel structures have more advantages. You can refer to the industry knowledge I wrote before. On the news page of the SAFS steel structure official website, today we will introduce its painting process:
Inspection and acceptance of paint coating for space frame steel structure:
1. During and after the surface paint coating construction, the painted workpiece should be protected to prevent flying dust and other debris;
2. Paint coating post-processing inspection, it should be consistent in color, bright in color, bright, without wrinkle and pimple;
3. To measure the thickness of paint film, use a touch-type paint film thickness gauge to measure the thickness of the paint film. The paint film thickness gauge generally measures the thickness of 3 points and takes the average value.
Space frame steel structure paint finished product protection:
1. After the space frame components are painted, they should be temporarily enclosed and isolated to prevent stepping on and damage to the coating;
2. After the space frame member is painted, if it encounters strong wind or rain within 4 hours, it should be covered to prevent dust and moisture from sticking to it and affect the adhesion of the coating;
3. When the painted components need to be transported, attention should be paid to prevent bumping, prevent dragging on the ground, and prevent the coating from being damaged;
4. Do not touch the acid liquid on the mesh frame components after painting to prevent the coating from being bitten.
The quality problems that should be paid attention to in the paint of space frame steel structure:
1. The temperature of the paint coating operation should be between 5 and 38 °C. When the weather temperature is lower than 5 °C, the corresponding low-temperature coating material should be used;
2. When the temperature is higher than 40℃, stop the paint coating operation. After treatment, the coating operation is carried out;
3. When the air humidity is greater than 85%, or there is condensation on the surface of the component, do not carry out the paint coating operation, or carry out the coating operation after treatment;
4. Before the production of the space frame structure, the hidden parts of the components and the parts of the structure interlayer that are difficult to remove rust should be removed in advance and painted in advance.
