Rainy Night Retroreflectometer For Road Pavement Painting from China

The rainy - night retroreflectometer is a portable on - site measurement instrument with an open light path, which is used to measure the retroreflection brightness coefficient of the marking line. Unit: mcd·m⁻²·lx⁻¹. This instrument can measure the retroreflection brightness coefficient of the marking line and the oscillating marking line under three conditions: dry R_L, wet R_(L_wet) and continuous rainfall R_(L_rain).

  • Equipment Preparation: Check the machine, ensuring it is capable of measuring in rainy conditions. Prepare an artificial continuous rainfall simulation spray device , and verify its functionality.
  • Set Up Rainfall Device:Place the artificial rainfall spray device over the marking surface to align the rainfall area with the test zone. Turn on the rainfall switch, adjust the pressure and atomization effect of the nozzles .
  • Position Measuring Instrument:Place the retroreflective marking measuring instrument in the designated position so that it can test the marking through the opening of the rainfall chamber.
  • Soak the Marking:Activate the artificial rainfall device to completely wet the test marking with water.
  • Measure Data:After the marking is fully soaked, maintain continuous rainfall and start measurement.

Why are Rainfall Simulation Devices Necessary?

Rainfall Simulation Devices
  • Controllability and Repeatability: Natural rainfall is unpredictable in terms of timing, intensity, and duration. Simulation devices allow researchers to set specific parameters, ensuring consistent experimental conditions. This consistency is crucial for comparing and validating data across scientific studies.
  • Efficiency and Cost Optimization: Field observations often require prolonged waiting for suitable rainfall events. In contrast, simulation devices can conduct multiple tests within hours, significantly reducing research timelines and minimizing labor and time costs.
  • Safety and Flexibility: When simulating extreme conditions (e.g., heavy storms or acid rain), these devices eliminate outdoor risks.
  • Data Precision: Equipped with sensors, rainfall simulators can monitor real-time parameters like precipitation volume, raindrop kinetic energy, and runoff changes.

ALL IN ONE Thermoplastic Paint Pre-heating Kettle & Line Marking Applicator Machine FAQs

Here are some frequently asked questions (FAQs) about all in one thermoplastic road marking machine:

Some advantages include:

  • No need of an extra expensive pre-heater kettle machine
  • Versatility in marking various types of road lines and symbols.
  • Cost-effectiveness compared to larger machinery for smaller-scale projects.
  • Precise application and control over the road marking process.

All in one thermoplastic paint applicators can create a wide range of road markings, including straight lines, dashed lines, arrows, symbols, letters, and more.

Yes, it is possible to apply reflective beads or glass beads onto the freshly applied thermoplastic paint for enhanced visibility during nighttime or low-light conditions. The beads can be sprinkled onto the paint surface before it cools and solidifies.

The drying and setting time of thermoplastic paint can vary depending on environmental conditions such as temperature and humidity. Generally, it takes a few minutes for the paint to cool and harden, allowing for traffic to resume.

After each use, it is important to clean the applicator thoroughly to prevent any paint residue from clogging the equipment. Follow the manufacturer’s instructions for maintenance and cleaning, including flushing the melting tank and application components with a suitable solvent or cleaner.
