In the setup of road traffic marking, thermoplastic marking is widely used in all kinds of road marking construction because of its strong durability, good reflective effect, construction efficiency and other characteristics. However, many first contact with the thermoplastic marking construction customers, often on its construction process there are misunderstandings, that as long as you have a thermoplastic road marking machine can easily complete the construction. In fact, thermoplastic marking construction is far more complex than room temperature marking construction, the following will be a detailed analysis of thermoplastic marking construction mistakes and professional skills.
First, misunderstandings of thermoplastic road marking construction
Many customers mistakenly think that thermoplastic road marking and room temperature cold spray demarcation similar, only need a thermoplastic road marking machine can be constructed. But in fact, thermoplastic road marking construction requires a series of rigorous steps and professional equipment. First of all, the road surface cleaning is the foundation, must ensure that the road surface is clean and dust-free, which is to ensure that the marking and road surface closely combined with the premise. Secondly, measurement and sampling is the guarantee of accurate construction, need to be in accordance with the design drawings for the point, and with latex material to put out the water line of the road edge line. Finally, the road marking paint process is the need to strictly control the temperature, paint ratio, glass bead spreading and other aspects.
Second, thermoplastic marking construction steps
Road surface cleanup: before construction, must arrange for a person on the road surface for thorough cleaning, to ensure that the road surface is clean and free of debris.
Measurement: on the basis of clean road surface, according to the design drawings for punching points, and white latex material to put out the water line of the road edge line, after checking the correct marking demarcation.
Marking line application:
- Add the thermoplastic paint into the thermoplastic kettle and heat it evenly to a suitable temperature (generally 180-200 degrees Celsius).
- In a good water line on one side of the uniform coating of road-specific undercoating agent, in order to enhance the adhesion of the marking line and the road surface, and to isolate the groundwater evaporation.
- Load the melted thermoplastic paint into the construction vehicle of the road marking paint machine and put an appropriate amount of glass beads in the bucket.
- Modulate the flow, wait for the primer to dry to a suitable degree, the formal construction. The construction is based on the water line to ensure the construction quality.
- Marking coating thickness needs to comply with the regulations, the surface of the glass beads should be spread evenly to ensure that the visual nature of the marking, reflective effect and the combination with the road surface.
Third, thermoplastic marking construction techniques
- Equipment selection: because the thermoplastic road marking paint needs to be heated to high temperature melting before use, therefore, small thermoplastic marking machine usually marking device and heating melting paint heating equipment separate and independent use, in order to improve the construction safety and melting efficiency. The initial marking construction team usually needs to be equipped with thermoplastic kettle, hand-push thermoplastic road marking machine, hand-push pre-marking machine and other equipment.
- Construction safety: in the construction process, should strictly abide by the operating procedures to ensure the personal safety of construction personnel. At the same time, should also do a good job of equipment maintenance and maintenance work, in order to extend the service life of the equipment and ensure the quality of construction.
- Construction cleanup: In the construction process, the road surface in the construction area should be cleaned up in time to ensure that the road surface is clean and pollution-free. Construction team in the construction of a certain distance, should be cleaned up in a timely manner in the region of the road surface, in order to keep the road surface clean and undamaged.
Fourth, ST-150 push-type thermoplastic road marking machine introduction
ST-150 push-type thermoplastic road marking machine is one of the early application of hot melt road marking machine because of its simple structure, small size, light weight, easy to load and transport, good operation, easy maintenance and other advantages. It has construction flexibility and equipment durability, can meet the needs of various road marking construction.
