Polyurethane is a polymer material synthesized by chemical reaction between isocyanates and polyols. The composition of polyurethane has great flexibility due to different production processes, uses and performance requirements.
Steps to repair the chrome-plated surface of industrial rollers:
1. Surface inspection and evaluation
2. Surface cleaning and removal of damaged layer
3. Surface repair and re-chrome plating
4. Surface polishing and passivation
5. Final inspection and quality control
In mass production, the consistency of printed products is an important criterion for measuring production quality. The high precision and durability of ceramic anilox rollers keep the ink transfer amount consistent within each printing cycle, avoiding color differences or printing defects caused by changes in ink volume.
As a highly efficient surface treatment equipment, the corona roller can significantly increase the surface energy of the material and enhance its bonding with other materials, thereby improving the quality and reliability of the product.
Water quenching rollers are mainly used to quickly cool metal workpieces that have been heated. Its basic structure includes rollers, cooling water distribution system and conveying device. The metal workpiece is heated to the austenite phase region (usually between 800°C and 900°C) in a high temperature environment, and then cooled by water quenching rollers to quickly cool it down.
An industrial water quenching roller is a device used in the metal heat treatment process. It quickly cools the metal workpiece on the roller surface to achieve the required hardness and material properties. This process is often called "quenching" and is a key link in heat treatment.
The thickness of tungsten carbide coatings is usually between 50 microns (0.05 mm) and 500 microns (0.5 mm), depending on the application scenario, working environment and use requirements of the roller. The choice of coating thickness must balance the wear resistance, impact resistance and other working characteristics of the roller.
Industries that need to use corona rollers: packaging industry, printing industry, electronics industry, automotive industry, medical industry, construction industry, etc.
Silicone rubber rollers are mainly made of silicone rubber. Silicone rubber is a special polymer material composed of a silicon oxygen chain (Si-O) as the main chain and has a structure of organic group side chains. This unique chemical structure gives silicone rubber many superior properties that other polymer materials do not have.
Based on the above factors, we have conducted research and analysis on the prices of industrial chrome-plated rollers on the market. The price of small chrome-plated rollers (US$300 to US$600), the price of medium-sized chrome-plated rollers (US$1500 to US$4000), and the price of large chrome-plated rollers (US$5000 to US$15000).
