Original: [Packaging operation] The disadvantages of adhesive thickener

Adhesives are one of the important materials for daily production, and are an important class of additives for water-based adhesives with low viscosity

Adhesive thickener

Yesterday introduced to you the advantages of adhesive thickener adhesive thickener and the interaction of adhesive thickener, today to introduce the disadvantages

There are three obvious disadvantages:

1.

Like sponges, sealants that use adhesive thickeners have strong water absorption when dried, which seriously affects the water resistance of

2.

The sealant system contains a variety of salts, these salts make the binder thickener water absorption plummeting, directly affect its thickening capacity, these salts include dispersants, anionic emulsifiers in emulsions, calcium in the filler, magnesium plasma, alkali soluble thickener neutralizes the formation of polymer polyacrylate, with the development of sealant, the more fine the powder, the more delicate the state, the dispersant becomes an indispensable sexual additive, and the dispersant is a strong ion of the electrolyte, which has a great

3.

Binder thickener absorbs water for thickening, such a thickening mechanism in the system to form a small clump paste, affecting the opening effect and performance, and the emulsion compatibility is also low, and its pulp appearance fineness is low, after curing the whole is poor, affecting the sealing adhesive adhesion and the adhesion force

Why should the adhesive be added to the thickener?

The adhesive adds water to dilute the various solutions during the blending process and eventually becomes the binder
