Compounding and Processing

Principles related to compounding and processing are discussed in subsequent 

The first mixer was an annular container with a spiked rotor for rubber compounding (Hancock 1823). The calendar/two-roll mill was patented by Chaffe in 1836 and manufactured by Farrel Co. A counterrotating twin-shaft internal mixer

Inductively coupled argon plasma (icp) and direct current argon plasma (dcp) atomic emission spectrometry are solution techniques that have been appHed to copper-beryUium, nickel—beryUium, and aluminum—beryUium aUoys, beryUium compounds, and process solutions. The internal reference method, essential in spark source emission spectrometry, is also useful in minimizing drift in plasma emission spectrometry (17). Electrothermal (graphite...

Some of the newer and more potent drugs, like the prostaglandins, which are produced at very low concentrations in the finished formulation, may require special precautions during compounding and processing in order to prevent loss of actives due to adsorp-tion/absorption to the walls of fill lines and/or storage tanks. 

Maintaining the stability of a biological treatment of wastewaters containing formaldehyde and urea is complicated because some compounds exert a toxic effect on the processes involved. Figure 19.5 shows the possible toxic interactions between the different compounds and processes.

The diisocyanates and polyols are reacted to form a high molecular weight hydroxyl terminated millable gum. These millable gums are compounded and processed as conventional elastomers, both sulphur and peroxides being used to cure the polymers. Here again, polyether and polyester types are available, and the differences between these two types referred to above also apply here. 

Fitted to an extruder a gear pump is particularly useful for difficult compounds and process conditions. The compound is softened and plasticised in the extruder and fed into the gear pump under low intake pressure. The gear pump intake pressure regulates the speed of the extruder so that the gear pump is always filled. The gear pump builds up the pressure required at the die. A screen can be fitted if desired.
