Mixing and melting

PBAs are generally prepared by three commercial methods [57,124] latex mixing, solution mixing, and melt mixing. 

Mixing and Melting Performance as a Function of Flight Clearance... 

The single crystals thus far prepared are too small for many physical property measurements. Also, the two techniques described for preparation of powders result in fine grained (and not sintered) materials which are also not appropriate for many measurements. A different technique, however, was recently developed which produces near theoretical density polycrystalline pellets (56). Stoichiometric mixtures of BaO, K02 and Bi2Os are mixed and melted in N2 gas and quickly quenched onto a copper block under the N2 atmosphere. The process must be performed... 

Extruders are available with capacity of more than 1 tonne/h, to mix and melt plastics and provide profiles, tubes, sheet, etc. They are mostly heated electrically, or else using circulating thermal oil, and can be used in pyrolytic systems for feeding plastics, straining the molten feed, eliminating HCl from PVC at temperatures up to some 400°C.

Sherman (1966) studied the viscoelastic properties of ice cream mix and melted ice cream. The creep-compliance curve for the ice cream mix was described by the relation ...

Plastication unit design. The role of the plastication part of the machine is to mix and melt the polymer and the additives, homogenize, pressurize, and feed the melt to the transfer section of the cylinder through the check valve. Plastication takes place at elevated temperatures (230°C-400°C) depending on the type of the plastic. Polyvinylidene fluoride is injection-molded at the lowest end of the temperature range while PFA is processed at the highest. 

Mixing and melting. Raw materials such as quartz, feldspar, dolomite, and spodumene are mixed with the nucleating agents, usually TiOi or Zr02, and melted. 

Commercial powders of reagent grade were mixed and melted in a platinum crucible for 1 h in an electric furnace at 1400°C. The melt was poured between two iron plates and the thickness of the obtained sample was 1.6 mm. The glass ceramic was obtained by thermal treatment of the precursor glass at 620°C for 2 hours. It was used to compare with measurements in the locally damage zone by laser action.
