Common Problems and Solutions of Hot-melt road marking-02


On the highway construction, road marking, we often encounter the some kind of problems. I have accumulated some experienceam through learning and practice in the long-term highway construction, the following are several common problems and solutions on the hot-melt marking construction i will share with you.

Discoloration issues
1. Melting temperature is too high or hot-melt process of burning the bottom of the kettle. Solution would be to strictly control the temperature, the operation carried out before the end of hot-melt tank cleaning.
2. Substandard quality of the product itself, is likely to paint deterioration. Number of products in the professional inspection prior to the construction sector should be tested, qualified only after construction of the use of.
Night reflective road line problem
1. issue a poorly reflective at night. Construction, the wind was being blown towards the larger glass beads; Spreader machine rocking tilt causes uneven surface scattering glass bead spreading. Solution is to install the windscreen glass Bo Sabu machine and make a painting operation of preparatory work, to master the speed of construction progress.
2. Premixed and surface impurity scattering glass beads too much into the circle rate is low, particle size distribution is poor, painting liquid does not meet the technical requirements, inadequate viscosity, softening point is too low and other reasons, will result in the phenomenon of night-time reflective ineffective. These are all products of inferior quality. Should be used in the construction of qualified products.
