Hot-melt glue sticks are often used in our industrial decoration. What is its function? How to use it? Come and have a look

1. What is the function of glue stick?
The glue stick is a one-component elastic deacidification type room temperature vulcanized silicone sealant with silica gel as the main raw material, and then add wall glue, antioxidant glue, accelerator glue, crosslinking glue, etc., and then use advanced Process synthesis of one-component room temperature vulcanization sealant, good anti-aging performance and waterproof performance, usually used for sealing ceramic tiles, glass, aluminum alloy, ceramics, bricks, and other general building materials, or used in some furniture manufacturing On the reinforcement.

2. Glue stick production process

• 1. Weigh the raw materials according to the glue stick formula ratio and add them to the reaction kettle. Increase the temperature to melt and stir evenly. Then cool the melted rubber in the reactor to a certain temperature and put it into the running extruder. The extrusion speed of the extruder can be selected according to the different types of rubber. The extruder squeezes the hot melt adhesive into the water tank through a trapped extrusion hole on the extrusion head. The hot melt adhesive is immediately shaped when it meets the cooling water. The glue stick is initially cooled and shaped through the first cooling water tank and passed through the tractor. In the second cooling water tank, the glue sample is fully cooled and shaped. The running speed of the glue stick in the water tank is controlled by the extrusion speed of the extruder, so that the pulling speed of the tractor and the extrusion The extrusion speed of the machine is synchronized.
• 2. Adjust and control the relationship between the speed of extruding the  glue stick, the cooling setting speed, and the traction speed, and then the cooled glue stick is cut and boxed into finished products
• 3. The glue stick is a solid adhesive made of ethylene-vinyl acetate copolymer (EVA) as the main material, adding a tackifier and other ingredients. It has fast adhesion.

3. How to use the glue stick

•  1. The glue stick should be used in conjunction with a glue gun. First, use a hot melt glue gun to glue.
•  2. Then put the glue stick into the hot melt gun, plug in the electric heating for a while.
•  3. At this time, when the trigger is pulled, there will be glue flowing out of the muzzle.
• 4. We can also directly burn one end of the glue stick with a lighter, apply it to the place where it is to be glued, and wait until the glue becomes solid. Glue sticks are used to bond paper cartons, handicrafts, hand-made, etc., which is convenient and easy to use, and is stronger than ordinary glue.
