Requirements for hot melt kettle marking technology
1, the inventory of pavement, pavement without water, oil and confirm the convex obstacles.
2, do the preparation before the construction work, the quasi marking range, line to be accurate,set up specifically for the review.
3, before the construction, mechanical inspection, special inspection of the following aspects:
The diesel engine, cooling water, lubricating oil level, the fuel level;
The marking machine, coating machine (scraping and spraying are according to the needs offilm thickness and linewidth adjustments), glass bead spreader (check the glass beadhomogeneity and the number is sufficient, pipeline is blocked)
4, clear the construction personnel responsibilities, insist to do the construction records, records should be the following: the road surface and the air temperature, relative humidity (%), weather conditions, wind direction, wind, road types, road conditions (road material type, recency, clean or not) coating melt temperature, coating amount of use, the construction length calculate thespreading rate, area.
5, coating the base oil, the coating should be slightly wider than the range of markings, coatingamount is 8 m / kg, all to be solvent volatilization before construction hot melt coating.
6, the monitoring of the temperature and surface temperature, during the construction of the temperature must be above the dew point temperature of 3 DEG C, when the surfacetemperature is lower than 9 DEG C, careful construction! Hot melt kettle sintered temperature should be considered during the construction of the weather and low temperature sintering,appropriately elevated temperature; high temperature appropriate to reduce the sinteredtemperature.
7, don't let the paint superheated hot melt kettle or construction in the car, coating temperatureshall not exceed 220 c! Construction of cautious thermometer hot melt kettle of failure!
8, hot melt kettle of the coating to be stirred evenly, but also to maintain the desired viscosityand temperature, the temperature is too high will make the coating is too thin, long time high temperature can make the paint color, paint after melt to continue stirring for 10 minutes todischarge.
