The role of magnesium sulfate in starch adhesive
The role of magnesium sulfate in starch adhesive mainly includes catalysis, drying, and can improve the bondin.
1. Catalysis: Magnesium sulfate can accelerate the curing process of starch adhesive and increase its reaction rate.
2. Drying: Magnesium sulfate helps to dry starch adhesives, shorten drying time, and improve production efficiency.
3. Stabilizers: Starch adhesives may be affected by factors such as temperature and humidity during storage and use, resulting in unstable performance. Magnesium sulfate can
serve as a stabilizer to help maintain the stability of starch adhesive properties. It can interact with starch molecules, reduce the aggregation and precipitation of starch molecules,
thereby maintaining a uniform state of starch gel for a longer period of time, extending the storage period and stability of starch gel.
4. Accelerator: It can accelerate the solidification process of starch glue and improve production efficiency. In some application scenarios that require drying speed, such as the
packaging industry, adding magnesium sulfate can make starch glue solidify faster, reduce waiting time, and improve work efficiency on the production line.
5. Enhance bonding strength: Magnesium sulfate can interact with other components in starch adhesive to enhance its bonding performance. It can promote the contact and
adsorption between starch molecules and the surface of the bonded material, improve the bonding strength, and enable starch glue to better bond different materials together.
6. Improving water resistance: Although starch glue itself has a certain degree of water resistance, it may not be sufficient in some situations where high water resistance is required.
The addition of magnesium sulfate can improve the water resistance of starch adhesive to a certain extent, reduce the erosion of moisture on the bonding area, and make the bonding
more firm and durable.
