Dissolving pulps are specialty pulps used for chemical conversion into products such as rayon, made by either a modified kraft (prehydrolysis) or sulfite process in which the aim is to obtain a pulp of pure cellulose. Since essentially all lignin and hemicellulose are removed, dissolving pulps have the lowest yields, on the order of 35%.
The suspension mixture, while passing between the rotor and the stator, is subjected to a tremendous shearing action which effects a fine dispersion of uniform size. • The shearing forces applied in the colloid mill usually raises the temperature within the suspension. Hence, a coolant is used to absorb the excess heat. 24. Colloid Mill 25.
How emulsions and emulsifiers work. Simple emulsions are either oil suspended in an aqueous phase (o/w), or water suspended in oil (w/o). Milk is an example of an o/w emulsion, in which the fat phase or cream forms tiny droplets within the skim milk, or water phase. In contrast, margarine is a w/o emulsion containing droplets of water or skim ...
