Two-Component Sprayed Marking Project in Yinzhou District, Ningbo

Construction Time:September 23, 2023 Construction Temperature：29℃ Construction Materials：SW402  SW402-03 Sprinkling Process：Surface-sprinkled High-brightness Glass Beads

Construction Notes

The construction was carried out at night with moderate temperature, and the curing time was normal, about 15 minutes.

SW402-03 whitening coating was adopted for the paint, and the whiteness of the marking lines was better than that of ordinary marking lines.

The yellow paint was more bright and vivid, and the double yellow lines had a more obvious warning effect.

The paint must be fully stirred before use, and the dosage of curing agent added to Component B must be fine-tuned according to real-time feedback.

The 300-type equipment with a booster cart was used in this construction, which greatly improved the construction efficiency. However, attention should be paid to controlling the spraying flow rate.

The old screeded marking lines were covered by spraying, resulting in an uneven surface, and the glass beads on the raised parts settled relatively shallowly.

The retroreflection coefficient was tested throughout the process for real-time quality inspection.
