Long-lasting wet night road marking made by RI glass beads

Road markings provide continuous guidance information for drivers. According to Chinese national standards, rainy night marking should have retroreflective performance under dry, wet and continuous rainfall conditions, and have a good visual recognition effect on rainy nights. At present, the rainy night marking test sections set up by many provinces and cities in China are all relying on the road ceramic glass beads (AW element) to achieve rainy night reflective performance. There is no rainy night markings with reflective performance lasting more than 3 months under wet or continuous rainfall have not been found. Cntory reflective glass beads, reflective road paint material always used for rainy night marking.


In order to overcome this problem, Shandong Highway proposed a ‘long-lasting life cycle reflective road marking’. From the construction of the marking to the end of the marking life (average daily traffic flow of 80,000, more than 4 years), it maintains good reflective performance under dry, wet, and continuous rainfall conditions, which is the first in China.


The detailed information of the trial section,

1. Retroreflectivity -- Dry: 730-820mcd, Wet: 280-400mcd.

2. Paint - thermoplastic.

3. Drop on and quantity-- 600g/m2 in total, 300g HR beads of type B, 300g 1.7 index beads of Type DHR. Using two dispensers, 1st one for Type B and 2nd one for DHR.

4. Intermix and quantity -- total quantity is 30% of thermoplastic, 15% of HR beads 0.3-1.4mm, 15% of 1.7 index beads 0.3-1.4mm.

Skid Steer Trenchers

  Skid Steer trencher features an adjustable depth control foot which ensures the operator trenches at a set depth at all times. This high engineered trencher has a number of features that make it a more long lasting, more productive unit than the competition. This trencher comes with an extended auger that carries dirt further from the trench. This prevents the dirt from fall in the trench. Three different chain options are also available for trenching in different ground conditions from general earth, to rocky ground, concrete, asphalt, and even frozen ground. Our trenchers and Trenchers Attachment are manufactured in-house to the highest industry quality, ensuring reliability and performance. The Trencher can be used for pipe laying for irrigation, underground power & communications, road repairs, general construction. Whether you rent trenchers occasionally for bigger jobs, or own trenchers that run constantly during the busy season, these machines make life...

Can laser cutting machine cut galvanized sheet?

Can laser cutting machine cut galvanized sheet? Galvanized sheet is a relatively common material used in manufacturing. Galvanized sheet is the steel sheet coated with a layer of metallic zinc on the surface which can prevent corrosion and extend its service life. So is this material suitable for laser cutting machines ? Generally for galvanized sheets, laser cutting machines can cut easily. Most organic and inorganic materials can be used. Various metal materials commonly used in industrial manufacturing systems are almost cut regardless of their hardness. Copper, aluminum and their alloy plates are all no problem. In the process of processing galvanized sheet, auxiliary gas needs to be added. The purity and pressure of auxiliary gas directly affect the quality of the cut sheet section. The oxygen purity for cutting should be above 99.6%. When the purity of the oxygen used for cutting is higher, the better of the roughness and quality for the section of galvanized sheet will be, of co...

What is inside a tubular motor?

  A smart tubular motor is a compact and powerful electric motor that is typically used to operate roller blinds, awnings, and shutters.  The main components of a tubular motor are: Housing: The tubular housing that gives the motor its name and protects the internal components from damage. Motor: The electric roller blinds motor that provides the power to operate the roller blinds, awnings, or shutters. The motor can be AC (alternating current) or DC (direct current), and it is typically a brushless type for longer life and improved performance. Gearbox: A gearbox that transmits the power from the motor to the roller blinds, awnings, or shutters. The gearbox may be planetary or worm gear, depending on the design and application. Encoder: An encoder that measures the rotation of the motor and provides feedback to the control system to ensure accurate positioning and smooth operation. Control Circuit: A control circuit that manages the operation of the motor, inc...
