The precipitation rate of PVDF in the cooling bath
was slowed down, so the porosity and average pore size increased slightly.
During the experimental tests carried out using the above mandrel, the material being deformed maintained continuous contact with the mandrel surface and subsequent free tensile drawing was controlled by cooling of the material in the cooling bath
A vacuum is created in the cooling bath
around the calibrator, and the tubing is pulled out into contact with the calibrator The gaps between the discs, or the holes in the sizing tube, permit the vacuum to act upon the plastic tube.
While the cooling baths
are relatively long for this process, it avoids the need for equally lengthy curing equipment required for mechanically foamed thermoset rubber.
This makes it possible to pelletize sticky materials, resins with poor melt strength (by coating them with a stiffer material), or water-soluble materials that would dissolve in the cooling bath
These profiles pass through a water cooling bath
and are cut with a traveling saw to 8-, 10- and 12-ft lengths.
After the thermoplastic is applied, the profile enters a cooling bath
Normally, as the water in the cooling baths
heats up, energy is spent to circulate this water through a heat exchanger in order to cool it back down.
The water for the strand cooling baths
passes through a five-micron filter and ultra-violet lights that destroy 100 percent of all microbes, providing a clean product for medical and food use.
The SFT-20 Liquid Carbon Dioxide Pump delivers a high flow rates (200 ml/min) without the need for external cooling baths
So growers often protect their fruit from blistering heat with cooling baths
from overhead sprinkler systems.
In the Italian capital Rome, where temperatures have been stuck above 35C for weeks, tourists were fined for taking cooling baths
in the Trevi and Four Rivers fountains.
It is used in addition to conventional external water cooling in vacuum tanks and cooling baths
to cool the moving pipe gently from the inside.
Corrodable metal parts on extrusion vacuum and cooling baths
have been replaced to advantage with machined plastics versions at Campex.
