What is the specific manufacturing process for printing blankets?

The specific manufacturing process for printing blankets includes the following steps:

1. Material Preparation: Printing blankets are made from multiple layers of specialized fabric and synthetic rubber compounds. Typically, printing blankets used in offset printing consist of a top fabric, middle fabric, and base fabric.
2. Coating and Foaming: The top, middle, and base fabrics are coated with different rubber compounds—surface paste, foam paste, and base paste, respectively. This step involves coating techniques where rubber is mixed with solvents like toluene to create a paste that is then applied to the fabric and dried.
3. Vulcanization: After the fabric layers are coated, they are combined and subjected to vulcanization, a process that uses heat and chemical energy to bond the fabric and rubber layers together.
4. Grinding: The vulcanized roll of printing blanket is then ground using a continuous grinding machine to ensure that the thickness variation across the blanket remains within 0.02mm per square meter, guaranteeing uniformity.
5. Environmental Measures: To reduce environmental pollution, some manufacturing processes avoid the use of solvents like toluene, opting instead for direct sheet production methods for making printing blankets.
6. Quality Control: Throughout the calendering process, quality control is critical to address potential issues such as uneven calendering, thickness control, uniformity in foaming, removal of impurities from the rubber mixture, and dispersion control.
