Precautions and construction specifications for hot melt marking

In the process of hot melt line marking, in order to ensure the construction quality and safety, it is necessary to pay attention to some key matters and follow the corresponding construction specifications. The following will introduce the precautions and construction specifications of hot melt line marking in detail.

1. Precautions for hot melt marking

Temperature control: The key to hot melt marking is to control the temperature. Too high or too low temperature will affect the quality and durability of the marking. Therefore, during the construction process, it is necessary to ensure that the temperature is controlled within an appropriate range, and select the appropriate heating temperature and heating time according to different types of hot melt coatings. Our thermoplastic paint heating temperature needs kept within 180℃-220℃.
Paint storage: Hot melt paint needs to be stored in a dry, cool place, away from direct sunlight and high temperature. Before use, make sure the paint has no lumps, hard lumps, etc., and stir it evenly.
Road surface preparation: Before marking, the road surface must be thoroughly cleaned to remove dust, oil and other impurities. Incomplete road surface preparation will result in insufficient adhesion between the marking and the road surface, and it is easy to fall off. And using water pre-marking line machine to do a pre-marker avoid faulty marking.

Coating quality: During the coating process, ensure that the paint is evenly applied to the road surface to avoid coating that is too thin or too thick. Uneven coating can cause color difference in the markings, uneven surface, and other problems.
Construction time: The best construction temperature for hot melt marking is 10℃-30℃. Avoid construction in bad weather such as rainy days, foggy days, and scorching sun. At the same time, avoid too long construction time to avoid overheating of the paint and quality problems.
Safety measures: During the construction process, protective glasses, gloves and other safety items should be worn to avoid paint splashing and injuring people. At the same time, attention should be paid to fire prevention, because hot-melt paint is flammable and explosive.

2. Construction specifications of hot melt marking

Material selection: Choose appropriate hot melt paint and reflective beads according to the project requirements and road grade. Different brands and models of paint have different performances. Choose paint with strong adhesion, wear resistance and good weather resistance. At the same time, the choice of reflective beads should also be based on the specific situation to ensure a good reflective effect of the marking.
Construction equipment: Choose appropriate hot melt coating melting equipment, marking vehicles, hand-push marking vehicles and other construction equipment to ensure that the equipment has good performance, safety and reliability. At the same time, the number of equipment should be reasonably configured according to the project volume and construction period requirements.
Construction process: The construction process of hot melt road marking includes pretreatment, melting, coating, and spreading reflective beads. Pretreatment mainly involves cleaning and drying the road surface; melting is heating the paint to a specified temperature; coating is evenly coating the melted paint on the road surface; and spreading reflective beads is spreading a certain density of reflective beads on the coating surface to improve the nighttime visibility of the marking.
Quality control: During the construction process, a strict quality control system should be established to conduct quality inspections on each process to ensure that the construction quality meets the relevant standards and specifications. At the same time, the finished product protection should be strengthened to avoid damage or contamination of the markings.
Environmental protection: During the construction process, attention should be paid to environmental protection, and the emission of construction noise, exhaust gas, and wastewater should be controlled to avoid adverse effects on the surrounding environment. At the same time, construction residues and waste should be cleaned up in time to keep the construction site clean.
Quality of construction personnel: Thermoplastic line marking construction personnel must undergo professional training and possess the corresponding professional skills and qualities. During the construction process, they must strictly implement safety operating procedures and comply with relevant laws, regulations and rules. At the same time, they must strengthen teamwork and communication to ensure construction quality and work efficiency.

Thermoplastic marking is a common road marking method with advantages such as fast construction speed, low cost and good reflective effect. During the construction process, attention should be paid to details and standardized operation to ensure that the construction quality meets the requirements and ensures safety and reliability. At the same time, it is necessary to strengthen technological innovation and research and development to continuously improve the level and application scope of thermoplastic marking technology.
