Protective glue

Protective glue is a commonly used packaging material used to protect items from damage, contamination, or the impact of the outside environment. The following is the production process of protective glue:

1. Material preparation: The main component of protective glue is polymer. Choose a suitable polymer resin as the base material, and add other functional additives as needed, such as plasticizers, stabilizers, etc.

2. Raw material processing: Weigh the polymer resin and other additives in proportion and mix them evenly. Then, the mixture is put into high-temperature and high-pressure equipment for melting processing to turn it into a plastic molten material.

3. Extrusion molding: The molten material is extruded and extruded through an extruder to form a continuous sheet or film. The extruder sends the material into the melting cavity through the screw, and uses pressure to make it pass through the extrusion die to form a continuous protective glue with a certain thickness.

4. Cooling and solidification: After the extruded continuous protective glue is cooled, it will harden and solidify. Cooling can be done by means of fans or cooling baths, for example. During the cooling process, the protective glue gradually solidifies and solidifies, allowing it to maintain its desired shape and structure.

5. Post-processing: The cooled and solidified protective glue requires subsequent processing and treatment. This includes removing excess edges or irregular shapes, cutting to the desired size and shape, and performing necessary surface treatments such as printing, coating, etc.

6. Packaging and quality inspection: The completed protective glue needs to be packaged and quality inspected. First, the protective glue is packaged according to the required packaging requirements, such as roll packaging, sheet packaging, bag packaging, etc. Then, perform a quality inspection on the packaged protective glue to check whether its size, thickness, surface flatness, physical properties, etc. meet the requirements.

7. Storage and distribution: After packaging and quality inspection, the protective glue can be stored and distributed. Protective glue needs to be stored in a dry, ventilated, and dark environment to prevent it from getting damp, deformed, or aged. During delivery, care must be taken to prevent the protective glue from being affected by extrusion, impact or other external forces.

The above is the production process of protective glue. According to different product requirements and production processes, the specific production process may vary, but generally it includes material preparation, raw material processing, extrusion molding, cooling and solidification, post-processing, packaging quality inspection, storage and distribution. During the production process, the quality and process parameters of each link need to be strictly controlled to ensure the protection of the final product.
