Application of Hot Melt Glue Sticker
1, Physicochemical properties
This product is white opaque (strong type), non-toxic, easy to operate, continuous use without carbonization phenomenon with rapid bonding, high strength, aging resistance, non-toxic, good thermal stability, film toughness and other characteristics. The shape is rod, granular.
2, Application
Hot melt adhesive stick is a solid adhesive made of ethylene-vinyl acetate copolymer (EVA) as the main material, adding tackifier and other components. With fast bonding, high strength, aging resistance, non-toxic, good thermal stability. It can be used for wood, plastic, fiber, fabric, metal, furniture, lampshade, leather, crafts, electronic toys, electrical components, paper products, ceramics, pearl cotton packaging and other mutually adhesive solids, which can be widely used in factories and families.
Used in plastics, metals, wood, paper, toys, electronics, furniture, leather, crafts, footwear, coating, ceramics, lampshade, pearl cotton, food packaging, speakers and other adhesive, through the hot melt glue gun, hot melt glue machine use.
Use the hot melt glue stick with the glue gun, put the glue stick into the hot melt gun, plug in the electric heat for a while, pull the trigger, the gun will have glue flowing out. You can also directly use a lighter to burn one end of the hot melt glue stick, apply it to the place to stick, stick it well, and so on. Bonded paper boxes, crafts, handmade, etc., both convenient and easy to use, than the general glue bonding firm.
3, Production technology
1) Weigh the raw material according to the formula ratio of the hot melt glue stick and add it to the reaction kettle. Heat it up to melt and stir well. Then cool the melted rubber in the reactor to a certain temperature and put it into the running extruder, and the extrusion speed of the extruder can be selected according to the different types of rubber. The extruder pushes the hot melt glue into the sink through a circular extrusion hole on the extruder head, and the hot melt glue is immediately shaped when it meets the cooling water. The glue stick is initially cooled and shaped through the first cooling water tank, and is pulled into the second cooling water tank by the tractor, in which the glue sample is fully cooled and shaped. The running speed of the glue stick in the sink is controlled by the extrusion speed of the extruder, so that the pulling speed of the tractor and the extrusion speed of the extruder are synchronized.
2) Adjust and control the relationship between extrusion speed, cooling setting speed and traction speed, and then cut and pack the cooled glue stick into finished products.
