The main reasons for the substandard reflection of two-component spraying markings include:

Reason A: Strong wind

Solution: Use a wind deflector

Reason B: The spreader spray width does not coincide with the reticle

Solution: Adjust the spreader so that the spray width coincides with the alignment of the reticle

Cause C: Uneven air pressure

Solution: Adjust the equipment so that the air pressure is even

Reason D: The paint film is too thin, the settling is not good, and the glass beads cannot be glued

Solution: Reduce the walking speed or increase the spraying pressure, increase the thickness of the paint film, or replace the smaller glass beads

Reason E: The temperature is too high, and the coating surface dries too quickly, which affects the settling of glass beads

Solution: Try to avoid construction during high temperature periods to avoid affecting the quality of the marking

Reason F: The viscosity of the paint is too high

Solution: Add diluent (100-200 grams) and adjust slowly, the settling effect of glass beads is obvious, and the viscosity of the paint is also high when the temperature is too low, and the construction temperature is recommended to be 5-40

Reason G: Use hot melt glass beads for construction

Solution: The surface of the hot-melt glass beads is coated with silicone oil, which is buoyant and cannot sink, and is easy to fall off

Reason H: The spraying pressure of glass beads is too low, and the settlement is not good

Solution: Adjust the oil-water separator on the bead sprinkler and increase the glass bead spraying pressure

Reason I: Poor quality of glass beads

Solution: Choose glass beads made of good materials, and the roundness rate is more than 90%

Reason J: The glass beads are sprayed unevenly, and the reflection is not up to the requirements

Solution: Check that the spreader is partially blocked

Reason K: Forgot to scatter glass beads

Solution: Be sure to remember to sprinkle glass beads

Reason L: Small amount of glass beads

Solution: Increase the spraying pressure and increase the amount of glass beads

Reason M: The size of the glass beads is not suitable

Solution: According to the thickness requirements of the drawing marking, choose the appropriate glass beads, which should ensure both the initial reflection and the long-lasting reflection

Reason N: The paint film is too thin, and the glass beads do not settle well

Solution: Increase the pressure or reduce the walking speed, increase the thickness of the paint film

Reason O: The quality of the paint is too poor, the adhesion is poor, and the glass beads fall off quickly

Solution: Before construction, do a test section to compare the paint performance of each manufacturer and choose a high-quality supplier

Reason P: There are impurities in the glass beads

Solution: Re-screen the glass beads to filter out impurities

Reason Q: The glass beads are damp

Solution: Place the glass beads in a clean and ventilated place to dry, crushing them into lumps
