The effect of barrel structures on the melt pressure of the melting zone with SI is shown in Fig.
* Hot melts do not require the posting of "Cancer Warning" signs.
This allowed using instead of a cylindrical shape the melt zone of the <<needle ear>> type [4], in which melt is on the end of the crystal portion being solidified and connects with the initial bar by a transition section of 10-15 mm diameter.
Smelter--Device that melts or fuses (as ore), often producing an accompanying chemical change to separate the metal.
HOT STUFF--Dark shrubs absorb more sunlight than snow does, so when bushes poke above the drifts, the surrounding air warms and snow melts faster.
where [[??].sub.w,s] is the total shear rate considering slip effect, [[??].sub.w,v] is the wall shear rate of melt for no-slip effect.
Differential-pressure control is useful with melt pumps to increase metering accuracy and control continuous screen changers.
Injecting flux chemicals in a controlled, measured amount below the melt surface provides for more environmentally friendly, efficient usage.
The typically smaller values for [a.sup.*] common to most rubber compounds (as compared to plastics), along with the smaller barrel-screw temperature differences employed in rubber extrusion justify assuming isothermal conditions for calculating flow rates in the melt conveying zone (ref.
Under such conditions, it takes more thermal energy than normal to increase the motion of the atoms or molecules enough to cause the solid to melt. Thus, increasing pressure typically raises a material's melting temperature.
Unlike electric are furnaces, which can melt up to 100 percent ferrous scrap, melts taking place in BOFs can usually contain no more than about 25 percent scrap.
In spring and summer, temperatures rose to a "balmy" 1 [degrees] C (34 [degrees] F), and the ice began to crack and melt. "You could break through a thin crust of ice just walking around," says Moritz.
The melt strength of polyethylene (PE) resins is an important property, one that is believed to determine the processing characteristics of a material during product forming.
"In-Mold Adjustable Rheological Control," or iMARC, is a new tooling concept that provides an externally adjustable means of varying how melt flows in a cavity without in any way restricting the flow (unlike valve gates, for example).
