Hot Melt Adhesive Process And Equipments | JCT Machinery

1.Raw Material Preparation

The main raw materials of hot melt adhesive are synthetic resin, rubber and additives. During the production process, these raw materials must be prepared and added to the reactor in a certain proportion for mixing.

2.Mixed Reaction

After adding the raw materials into the reaction kettle, the mixing reaction is carried out. In the process, the temperature and time of the reaction need to be controlled to ensure the full progress of the reaction. When the reaction is completed, a viscous paste-like substance will be produced, which is the raw material for hot melt adhesive production.

3.Thickening Treatment

In order to improve the viscosity and storage stability of hot melt adhesive, the raw materials need to be thickened. The specific method is to add thickeners such as capillary powder to the reaction kettle and stir again.

4.Forming

The thickened hot melt adhesive is molded through a molding machine. The molding machine extrudes the hot melt adhesive into strips or granules, which facilitates subsequent storage and use.

5.Packaging and Storage

The formed hot melt adhesive will be packaged. Common pakaging methods include cardboard barrels, plastic barrels, etc. The storage condiitions of hot melt adhesive require dry, cool, ventilated and avoid direct sunlight and high temperature environment to maintain its stability.
