Introduction to the properties of thickeners

I. Use of the thickener

The thickener is suitable for printing and dyeing industry, for coating, dispersing printing color paste in the water phase thickener.

Second, Qingdao Kelun thickener main classification

Coating printing thickener

Active printing thickener

Dispersed printing thickener

Third, the thickener with the printing and dyeing process

The thickened color paste has good stability and large adjustable range of viscosity, which can be used in almost all kinds of paint printing process, such as round net, flat net, machine printing, spraying, hand printing and so on.

The compatibility of thickening agent and adhesive

It belongs to anionic type, it can match well with all kinds of acrylate adhesives widely used nowadays, but it is not suitable to be used with cationic adhesives (e.g. Accra gelatin) or cross-linking agent (EH), etc. If the type of adhesive used is unknown, it is recommended to do small sample test first.

Fifth, the thickening agent dilution

Thickener of the water phase thickening is the result of a combination of factors, in general, the thickener concentration and rotational viscosity value is not a linear relationship, that is, when the dosage doubled, the viscosity value does not happen to be the original two times.

Sixth, the influence of the thickener water quality

Thickener dosage and water quality has a great relationship, most manufacturers use softened water or well water slurry. Generally speaking, the high salt content of well water, the dosage of thickener is correspondingly large, and the use of softened water, the dosage is relatively small, the region is different, there are differences in water quality. In addition, changes in climatic conditions, also caused by fluctuations in water quality, therefore, major manufacturers according to local water conditions, to determine the dosage. In terms of paint printing color paste, the role of the thickener is to thicken the color paste, and printing fastness depends mainly on the nature of the binder used and other additives with the matching situation.
