Reflectives Sheeting

In view of the different characteristics of PET, PVC and acrylic materials, what adjustments or optimizations are made in the production process of PET PVC acrylic reflective sheeting?

Adjustment and optimization of PET reflective sheeting production process
PET material characteristics: PET (polyethylene terephthalate) is widely used in the field of reflective materials due to its excellent transparency, good mechanical properties, weather resistance and recyclability. Its high crystallinity and low water absorption give PET reflective sheeting excellent optical properties and long-term stability.
Adjustment and optimization of production process:
Precision calendering: Using HANKER's advanced calendering technology, the thickness uniformity and surface flatness of the PET substrate are precisely controlled, laying a solid foundation for subsequent coating processes. By optimizing the calendering temperature and pressure parameters, it is ensured that the material has sufficient strength to resist stretching and bending during processing while maintaining high transparency.
High-precision coating: Using micro-replication technology, a reflective layer containing glass beads or micro-prism structure is evenly coated on the PET surface. HANKER's high-standard silicon coating machine and PE coating machine can accurately control the coating thickness and uniformity to ensure the maximum reflective effect. By optimizing the coating formula, the wear resistance and weather resistance of the reflective layer are improved, and the service life of the reflective sheet is extended.
Environmental protection treatment: After the reflective layer is coated, the waste gas generated is treated using RTO (regenerative thermal oxidation) environmental protection equipment to ensure that the waste gas treatment rate reaches 99.9%, which meets environmental protection requirements. At the same time, the recyclability of PET materials is also in line with HANKER's sustainable development concept.
Adjustment and optimization of PVC reflective sheet production process
PVC material characteristics: PVC (polyvinyl chloride) has the characteristics of low cost, easy processing, and good flexibility. It is a common choice in reflective materials. However, the weather resistance and environmental protection of PVC are relatively weak, and special attention should be paid to environmental protection treatment and material modification during the production process.
Production process adjustment and optimization:
Modified PVC formula: HANKER improves the weather resistance and anti-aging properties of the material and extends the service life of the reflective sheet by developing a modified PVC formula. Optimize the plasticizer and stabilizer in the formula, reduce the use of harmful substances, and meet environmental protection requirements.
Efficient calendering and coating: Use advanced calenders and coaters to achieve precision calendering of PVC substrates and uniform coating of reflective layers. By precisely controlling production parameters, ensure that the optical and physical properties of reflective sheets are in the best state.
Environmentally friendly treatment and recycling: Although PVC is relatively weak in environmental protection, HANKER reduces environmental pollution during the production process through strict waste gas treatment processes and material recycling mechanisms. Actively develop environmentally friendly alternatives to PVC to promote the green development of the reflective material industry.
Adjustment and optimization of acrylic reflective sheet production process
Acrylic material characteristics: Acrylic resin has become a high-end choice among reflective materials with its excellent weather resistance, high transparency and good processing performance. Acrylic reflective sheets have the characteristics of bright colors, strong reflective effects and good weather resistance.
Production process adjustment and optimization:
High-precision processing: Use HANKER's precision processing technology to ensure that the flatness, thickness uniformity and surface finish of acrylic substrates meet the highest standards. By optimizing processing parameters, reduce material loss during processing and improve production efficiency.
Innovative coating technology: Using advanced synthetic resin technology and film technology, combined with micro-replication technology, a fine reflective layer is formed on the acrylic surface. By optimizing the coating formula and process parameters, the reflectivity and wear resistance of the reflective layer are improved to ensure that the reflective sheet can still maintain a good reflective effect in various harsh environments.
Environmental protection and sustainability: Acrylic materials themselves have good environmental performance. HANKER uses environmentally friendly solvents and additives in the production process to reduce the emission of harmful substances. Through the material recycling and reuse mechanism, the resource consumption and environmental pollution in the production process are reduced.
