Key words: campus marking, playground marking, runway, hot melt, normal temperature, marking machine

Problem background: with the continuous expansion of the school scale, the phenomenon of campus socialization is becoming more and more obvious, and the traffic safety on campus is becoming increasingly important and has been widely concerned. As the administrative area, teaching area and living area of the school are relatively concentrated, the flow of people will peak when students go to and from class. The diversified traffic modes of motor vehicles and non motor vehicles in the campus have brought certain hidden dangers to the safety management of the campus. Therefore, it is of great significance to rationalize the setting of campus traffic signs and markings to improve the school traffic safety management and enhance the campus image. The introduction of traffic signs and markings into schools in primary and secondary schools is a way for children to know relevant signs and markings and the meaning of these signs and markings from childhood, so as to cultivate children's traffic awareness and lay a solid traffic safety awareness and habits when they go out of school and into society in the future;

Solution recommendation A (hot melt)

Lxd400 hydraulic double cylinder hot melt kettle

Hydraulic single cylinder kettle adopts hydraulic transmission mode, independent cylinder body and imported four ring fire high-efficiency energy-saving burner, which is suitable for the construction of small projects in parking lots, property communities, factories, enterprises, wharves and other places.

Equipment characteristics:

① Small size, light weight and convenient handling

Lxd860 advanced manual hot melt marking machine

The hot melt marking machine is the key equipment for hot melt marking construction. It is used together with the hot melt kettle to complete the marking construction. The equipment is designed with many unique new features, such as lightweight, portable, easy to operate, easy to maintain, etc.

Equipment characteristics:

① The specially manufactured high-precision integrated cast iron scoring bucket is used to ensure that all scoring buckets have neat edges, heads, uniform thickness and beautiful line shape

② Heat resistant rubber special cast iron wheel hub, high temperature resistance, long service life;

③ The glass bead synchronous clutch seeder is more uniform than the adjustable seeder on the market;

④ The trolley can be linked with LXD moped, which can greatly improve the construction efficiency of high-speed marking;

Solution recommendation B (cold paint)

Lxd-6l hand push high pressure airless cold spray marking machine

The hand push cold spray marking machine is a high pressure and equal flow airless spraying machine. The machine uses the gasoline engine to drive the hydraulic system to drive the single plunger pump, so that the paint forms a high pressure in the machine for spraying. The thickness of the marking is uniform and the edges and corners are neat. It is accurate and convenient to adjust the spraying width. It has the characteristics of low labor intensity, fast and convenient construction, etc.

Equipment characteristics:

① Hydraulic piston pump with stable pressure, high efficiency and good sealing performance

② Inflatable wheel hub, with obvious shock absorption effect;

③ Lifting design of guide rod of spray gun rack;
