Abstract: The line width of the hand-push type marking machine is determined by the width of the hopper, which is usually 100mm, 150mm, 200mm. Hot melt coatings need to be heated to between 180-230 degrees Celsius to apply.

The method of marking construction can be roughly divided into manual marking method and mechanical construction method from the result of line drawing machine. Manual marking is the most important and commonly used construction method for hot-melt marking construction. The marking width of the hand-pushing marking machine is determined by the width of the hopper, which is usually 100mm, 150mm, 200mm. The hot-melt paint of the road marking paint manufacturer needs to be heated to 180-230 degrees Celsius to be applied. The working principle of the hand-push marking is to use the scraper coating method. During the construction, the solid cover-like paint is put into the hot melt In the kettle, after melting and flowing, put it into the thermal insulation barrel of the hand-push marking machine. When marking, the molten paint is introduced into the marking bucket. The marking bucket is placed directly on the road surface. Because there is a certain gap between the marking line and the ground, when the marking machine is pushed, it will be scraped out by automatic flow. Marking. While scratching the marking line, the scribing machine can simultaneously spread a layer of reflective glass beads on the uniform surface of the marking line.

1. The advantage of this hand-pushing pavement hot-melt marking machine is that it has less construction equipment, long service life, and can be used for 3-5 years. The marking effect of the marking is better, the anti-pollution ability is strong, it can maintain the vividness for a long time, has good adhesion, excellent wear resistance and durability. The construction of hot melt coatings should be prepared in advance, such as warning posts, auxiliary tools, construction warning signs, and necessary drawing boards, fonts, etc. Pavement sweeping: first of all, carry out basic treatment of pavement, and remove pavement debris. If pavement debris is difficult to remove by conventional methods, use a steel brush pavement remover to remove it hard, and then use a wind cleaner to blow the pavement debris, eventually reaching the pavement cleaning standard that meets the marking requirements.

2. Construction Stakeout: Within the scope of the construction section, according to the construction drawings and technical requirements, measure the payout to facilitate the control of construction standards. After completing the lofting, conduct a preliminary inspection. The initial inspection is qualified, and then the supervision engineer is asked to accept. The next procedure can only be carried out after acceptance. Attentions for road marking construction: During construction, first use a high-pressure wind road cleaner to blow away the dirt and other debris on the pavement to ensure that the pavement is free of loose particles, dust, asphalt, oil and other debris that affect the quality of the marking and dry.

3. Then use the automatic pay-off machine and auxiliary manual operation to release the wire in the planned construction section according to the engineering design requirements, and then use the high-pressure airless under-coating agent sprayer to spray the same type and amount as the supervision engineer approves After the primer (primer) is fully dried, the self-propelled hot-melt marking machine or walk-behind hot-melt marking machine shall be used for marking.
