Micro-prismatic reflective tape is a relatively common reflective film product, and its application in daily production and life is also becoming more and more extensive. With the continuous improvement of market demand, people also put forward higher standards for micro-prismatic reflective tape products.
Here is the content list:
●What is the key to the manufacturing technology of micro-prismatic reflective tape?
●What is the application prospect of micro-prismatic reflective tape?
Although the basic principle of reflection of the micro-prismatic reflective tape is simple, its manufacturing technology involves multi-disciplinary high-tech fields such as material science, optics, and precision machinery manufacturing. In summary, there are four key technologies for manufacturing micro-prismatic reflective tape.
1. Unit structure and its array design: traditional prism-type retroreflective materials have some shortcomings. The method to solve these problems mainly depends on the design of the retroreflective unit structure and an array of the micro-prismatic reflective tape, such as changing the angle of the three planes to have a certain distribution or arranging the unit array according to a certain rule. However, due to the complexity of the structure and array design, it causes great difficulties in the production, replication, and demolding of the motherboard after molding, and it is not easy to realize it.
2. Production and replication of the motherboard: because the reflective unit of themicro-prismatic reflective tape is irregular in shape, the arrangement on the plane is regular, and the finish of the molding surface is high, so the motherboard needs precision processing. The plate itself does not directly participate in the forming, the processing cost is high, the area is limited, and the number of cycles of mold use is not high. The replica mold can be made by replicating the motherboard and spliced into any size, which is convenient for industrial production.
3. Determination of substrate: as amicro-prismatic reflective tape, the main material is engineering plastics. According to the different requirements of the performance of the micro-prismatic reflective tape, different plastic bases are selected. The main problems to be considered and solved are the weather resistance of the material, the preheating performance of the plastic substrate and its rheological properties, etc.
4. Embossing technology: as themicro-prismatic reflective tape has extremely high requirements on optical performance, its embossing accuracy is also quite high. During the embossing process, no defects such as poor flow, bubbles, scratches, etc. are allowed. The micro-prismatic reflective tape is also very harsh on some of the production process conditions, such as temperature and pressure.
As themicro-prismatic reflective tape has extremely high reflective intensity and good wide-angle performance, with the continuous improvement of motor vehicle speed, the continuous growth of high-grade highways, and the continuous complexity of road conditions, the application range of micro-prismatic reflective tape will become wider and wider. However, the high strength of micro-prismatic reflective tape brings other problems, such as glare, and the contrast between the pattern and the background in practical applications, which determine that the micro-prismatic reflective tape cannot completely replace the glass bead reflective film.
