There are four key elements to harm the inverse transmission coefficient of hot melt mark paint:

1, the chromaticity elements of hot melt marking paint immediately harm the inverse transmission coefficient of road marking.

2, the selection of glass beads is very important, as far as possible to select the circular rate of glass beads above 80%, the size of beads will harm the inverse transmission coefficient.

3, engineering construction temperature control is very important, engineering construction material temperature will harm the inverse transmission coefficient, control good material temperature, ensure that 50%- 60% of the beads embedded in the road marking coating, this time the effect is very good.

4, glass beads spread to be symmetrical, spread too much or too little is the inverse transmission coefficient will harm road markings.

What harm does the ground temperature too low have to the hot melt line coating during the construction?

The ground temperature is too low, will cause the high temperature of the building coating in a short term refrigeration, immediately harm the hot melt line coating itself and the middle of the asphalt road combined temperature. The lower the ground temperature is, the more obvious the development trend of the folding is, and the larger the folding level is, the greater the ground stress is. When the folding stress exceeds the compressive strength level of the building paint, the compressive strength of the road marking can not resist the essential folding stress, and the road marking will crack, resulting in cracks.

Why is the use of two-component line paint more and more common in high and ultra-low temperature natural environment?

Two-component marking paint has excellent aging resistance, does not cause ultra-low temperature cracking, high temperature soft, basically no embrittlement in the application, two two-component convergence reflected after the formation of network structure molecular structure, the architectural paint in each two-component close contact for the overall compactness, so that road marking and road surface solid fusion. Therefore, in the high and ultra-low temperature natural environment, the use of two-component road marking is more and more common.

What is the effect of base oil used in hot melt line coating?

Bottom oil, also known as lower coating agent and bottom adhesive, is used for the early solution of the ground before the construction of hot melt marking line coating engineering, and is the adhesive between hot melt road marking line and the ground. The solvent in the substrate is very easy to wet the ground. In addition, in the wet ground, the epoxy resin in the base adhesive covers the coated ground and produces a coating, which is conducive to the integration of the coating with the building coating at high temperature, and has the effect of improving the adhesion force between the road marking and the ground.
