In the extrusion of SSE with grooved
feeding zone, it was generally found that the melting quality was poor and the extrusion was not stable because the melting efficiency of the melting zone did not match the delivery efficiency of the feeding zone.
Pressures exceeding 12,000 psi have been achieved at the end of the grooved
section, so care must be exercised in design to prevent over-pressurization of the barrel.
The ability to make grooved
trouser test specimens went through a development process.
piping systems offer advantages in laying pipework cross-country that can make them a superior choice to traditional joining techniques.
Victaulic, the world's largest manufacturer of mechanical pipe joining systems, said consultants and the contractor chose its grooved
products when faced with what it said was an exceptionally large install and a very tight time frame.
Besides being notable structures, they all make use of grooved
piping instead of welded piping.
drums skimmed up to three times as much oil as the smooth drums did, the researchers report online for an upcoming Environmental Science & Technology.
There are a number of reasons why suction rolls are sometimes grooved
. Grooving provides knuckles of high pressure, thought to aid in the transfer of water from the sheet to the felt under the action of the pressure in the nip.
pins could not solve the problem, as the peaks would shear off during installation.
"But no other theropod is known to have had a grooved
, smooth-edged tooth like this." Meat-eating dino teeth usually feature serrated or jagged edges.
feed-section temperature should be raised to 210 F, just below the melting point of the LLDPE.
It is the usage of the grooved
feed section that most influences the efficiency of the extrusion process.
rolls and grooved
Vacrolls complete the sheet stabilization requirements of the Uni-Run sections.
Most popular grooved
patterns can be accurately reproduced, and lineal grooving speeds to 40 inches per minute are possible, ac-cording to the literature.
