Starch glue is a natural adhesive based on starch, which is commonly used in the manufacture of corrugated board boxes, stamp gluing, wood processing, book binding, etc. According to the requirements of different uses, with different starch as the base material and corresponding additives, it can be made into starch glue with different viscosity, solid content, color and mechanical properties.
However, no matter what kind of starch glue preparation process, foam accumulation or overflow often occurs due to various problems, so we can choose to add an appropriate amount of starch glue defoamer to improve the efficiency of construction and save costs. So,Starch gum defoamerWhat are the main advantages and how to use them?Today, I will explain the relevant knowledge in detail for you, I hope it will be helpful to you.
First, the main advantages of starch glue defoamer
Starch glue defoamer can quickly eliminate the foam in the glue and ensure the smooth progress of the production processThe starch gum defoamer also has a long-lasting antifoam effect, which can prevent foam from re-generating and ensure the stability of the production processBy eliminating foam, starch glue defoamers can improve the quality of starch glue, making it more uniform and firmly adhered to the surface of objects, etc.
Second, the use mechanism of starch glue defoamer
1.Physical Action:The ingredients in the starch gum defoamer are able to quickly diffuse into the foam, destabilizing the foam, causing it to burst and gradually disappear.
2.Chemistry:The ingredients in some starch adhesive defoamers are able to chemically react with the components in the glue, reducing the surface tension of the glue and thus reducing the formation of foam.
3.Surfactant role:The surfactant in the starch glue defoamer can reduce the surface tension of the glue, causing the foam to burst and gradually disappear.
