Glass Beads for Road Marking and Machine Vision in Automatic Driving Technology Glass beads are commonly used in road marking to enhance visibility and retroreflectivity of the markings, particularly in low-light conditions. These beads are embedded in the paint or thermoplastic material used for road markings, and reflect light back towards the source, making the markings more visible to drivers. Some people wonder whether automatic driving technology will eliminate road markings. At present, the answer is no. In the context of machine vision in automatic driving technology, the retroreflective properties of glass beads can also be useful for helping automatic vehicles navigate roadways. Specifically, the reflective properties of the glass beads can help sensors on the vehicle detect and identify the location and boundaries of the road markings. This information can be used to help the vehicle stay centered in its lane and navigate safely and accurately. To make the most of the retroreflective  properties of glass beads in automatic driving， it is important to carefully select the type and quality of glass beads used in road marking. Factors such as the size, shape, and refractive index of the beads can all affect their retroreflective properties and the accuracy of the information they provide to sensors on automatic vehicles. Overall, glass beads used in road marking can be an important tool for improving safety and visibility on roadways, and can also be useful for machine vision in automatic driving technology. By carefully selecting and using high-quality glass beads, it is possible to enhance the effectiveness of road markings and improve the accuracy and safety of automatic vehicles.

Is Two-Component Road Marking Paint More Economical Than Hot-Melt Paint in Long Term? Generally speaking, two-component road marking paint is considered to be more durable than hot melt road marking paint, which can provide long-term economic benefits. Two-component road marking paints are typically made by MMA resin and a hardening agent that are mixed together before application. This forms a hard and wear-resistant coating that can withstand high traffic volumes and bad weather. However, two-component road marking paint is more expensive to buy and use than the hot-melt paint. The application process for two-component road marking paints requires specialized equipment and experienced operators, which will increase the cost. Additionally, two-component road marking paints require longer curing times than hot melt road marking paints, which can result in traffic jam and decreased productivity. In conclusion, the economic advantage of two-component road marking paints over hot melt road marking paints will depend on the specific needs and requirements of the road or projects. It's important to consider factors such as traffic volume, climate, and maintenance requirements when determining the most cost-effective road marking solution.

Prevention of marking lines cracking To prevent the road markings line get cracked, except choosing the qualified raw materials and proper preparation of the road surfaces. The application under favorable conditions is required, the following precautions should be taken when construct with thermoplastic paint. 1. Put the paint into the reaction kettle to heat up. The temperature should be increased step by step. Stir while heating, and do not heat it violently, which may cause cracking due tolocalpartial overheating. 2. Stirring for a sufficient time, wait until the temperature of the upper and lower layers is consistent, and the materials are completely mixed evenly before starting to draw the line. 3. Try to draw the lines at a time with small temperature difference between air and ground. If in summer, the ground temperature is the highest at noon and should be avoided, the suggested time is from 6:00 am to 10:00 am and 4:00 pm to 7:00 pm Tory produces reflective glass beads, the high-quality glass beads for thermoplastic road marking paint, and we can provide the technical support on paint and construction.

How to maintain the road markings To maintain the retroreflective performance of road markings, regular maintenance and upkeep are necessary. Here are some steps that can be taken to maintain the road markings: 1.Cleaning: Regular cleaning of road markings can help to remove dirt, dust, oil and other contaminants that can builded up on the surface of the road markings and reduce its retroreflective performance. A pressure washer or a cleaning solution specifically designed for road markings can be used to clean the road markings. 2.Reapplication of retro-reflective glass beads: The retro-reflective glass beads used in road markings can be get off over time, which will reduce the retroreflective performance of the markings. To restore the retroreflective performance, retro-reflective glass beads can be reapplied to the surface of the road markings. 3.Repair of damaged road markings: Damaged road markings, such as cracks and gaps, can reduce the retroreflective performance of the road markings. Repairing damaged markings, such as filling in cracks and gaps, can help to restore the retroreflective performance of the markings. 4.Regular inspection: Regular inspections of road markings can help to identify any areas of the markings that need to be cleaned, repaired, or have reflective glass beads reapplied. This can help to maintain the retroreflective performance of the road markings over time. 5.Use of high-quality materials: Using high-quality road marking materials and retain its retroreflective performance can help to ensure that the road markings maintain the retroreflective performance over time. It's important to note that the frequency of maintenance and upkeep will depend on several factors, such as the location of the road markings, the traffic flow, and the local climate. To ensure that road markings maintain its retroreflective performance over time, it is recommended to follow a regular maintenance schedule and solve any issues with the markings promptly. If you need to re-spraying glass beads, you can refer to the products in this link: https://www.cntory.com/glass-beads-for-road-marking_c1 In this page you can find Tory HR glass beads, which have wide distribution range of sizes from 100um to 5000um, stable refractive index, and low content of heavy metals. Applying it to road marking construction helps to improve the properties.

Difference between one-component and two-component road marking paint There are one-component paint and two-component paint for road marking. One-component paint is usually ready-to-use, and it can be film-dried by evaporation of solvents or by direct reaction with certain substances in the air, such as moisture. On the contrary, the two-component paint is generally used by mixing A and B in a certain proportion. It is cured by a reaction between the two materials, then a certain thickness of film is formed in the base plane. The two type road marking paint are easily confused. For the one-component paint, put the high solid content paint (the resin is also pre-polymerized) into two barrels, then add initiator (or curing agent), and use two-component equipment for construction.The spray thickness can be reach 600-800μm, drop the reflective glass beads on the paint surface is also available. Moreover, it is very close to the smell of two-component paint. But there are some differences in their lift time and reflective properties. Therefore, when purchasing two-component road marking paint, you could ask for the product technical data sheet to avoid loss. Tory has developed a two-component road marking paint with superior adhesion and surface strength based on the characteristics of MMA resin. If you have the same demand on two-component paint development, you could view its detailed technical parameters via the link provided below: https://www.cntory.com/2-components-paint-mma-resin_p31.html

Abrasion of two-component thick paint marking lines When the road surface is relatively rough and has a deep structure, it is suitable to use the two-component sprayed reflective road marking line. The two-component marking line is commonly called acrylic after the pure resin curing reaction is complete because it is a reaction curing film.Acrylic is an important plastic polymer material that was developed earlier. Due to its special chemical structure, the marking coating film formed has high hardness and high wear resistance of the marking line. It is difficult to grind the pre-mixed glass beads out. Even if the inner mixed beads are ground out, the reflective performance will be basically lost. Please see the picture below: Above: Corrosion and wear on the surface of reflective glass beads RI1.5 on the left, RI1.9 in the middle, and long-life wear-resistant glass beads on the right (Note: high refractive index ≠ wear resistance, corrosion resistance, but high refractive index, wear resistance is relatively high) As a result, after a few years of use of the two-component thick coating marking line, the reflective performance will be reduced. At this time, marking maintenance is required - removing the line and re-drawing or spraying to cover other reflective marking lines. It is recommended that the thickness of the marking line is not less than 1.2mm, and the amount of paint per square meter is about 2 kg. The thickness of the coating formed in this way can effectively cover the road surface and sprinkle glass beads on the cladding surface, prolonging the service life of the marking line.
