PEC deposition yielded an additional increase of about 13% in dry strength
beyond what could be achieved by treatments that did not involve complexation.
Some examples of this coagulant concept being used in different parts of the industry include internal size promotion or fixation, efficiency gains for wet end starch and dry strength
additives, optical whitener quenching, incoming water color removal, effluent neutralization prior to the clarifier, dual polymer retention systems, and drainage aids for save alls and forming fabrics.
As mentioned before, starches were traditionally used for imparting dry strength
and enhancing surface integrity when paper was made primarily from fiber.
Normally, this bentonite isn't used by aluminum foundries due to its high hot and dry strength
, and because the effective temperature of destruction for this clay is well above the pouring temperature of the molten aluminum.
Strength: Experience here is mainly with starch, but dry strength
and wet strength agents can be considered in a similar way.
Non-allergenic Soft natural feel Excellent wet and dry strength
Superior absorbency compared to any other fiber Exceptional dry feel when wet compared to viscose rayon Unrivaled wipe dry performance Low static Comfortable and cool in the summer
Control problems with moisture, clay content and mulling efficiency can cause high hot and dry strength
problems, which cause poor sand breakdown and retention at shakeout.
Then, depending upon whether the grade is tissue or towel, a resin providing dry strength
, or both wet and dry strength
, can be recommended.
also is used sometimes to complement the green strength data by relating to the sand's shakeout properties of the sand.
These emulsions of acrylate copolymers combine properties such as heat reactivity, excellent adhesion characteristics and wet and dry strength
