MELT TEMPERATURE [22 records]

Record 1 2013-11-01

English

Subject field(s)
  • Magnetic Materials and Ferromagnetism
CONT

A liquid magnet.... The melt of an alloy(Co80-Pd20) which is ferromagnetic in the solid state at room temperature was undercooled below its melting point. The freely suspended droplet(diameter approx. 7 mm)-processed in the coil of an electromagnetic levitation facility-was attracted by a permanent magnet when the temperature approached the Curie temperature(lower picture). The attractive force depends on the temperature in a way characteristic for ferromagnetic materials. This appears to be the first demonstration for the possible existence of long-range magnetic order even in a liquid.

English

Subject field(s)
  • Plastics Manufacturing
CONT

Parts made from partially crystalline engineering polymers should preferably not be made by hot runner injection moulding if a perfect surface finish is essential. It is advisable to make use of a subsidiary runner, which thermally isolates the nozzle from the moulded part, thereby reducing the risk of surface defects.

OBS

Runners can be classified into two types, namely the cold runner and the hot runner. The mold temperature for the cold runner is similar to the mold temperature for the cavity. The material in the cold runner will eventually solidify, and be ejected with each cycle. The hot runner maintains the polymer at a melt temperature, either by insulation or by heating. This keeps the material fluid. Hot runners are not ejected with each cycle.

  • hot-gate molding
  • hot runner molding

  • hot-runner injection molding

  • Fluid Mechanics and Hydraulics (Physics)
CONT

Usually, Marangoni convection is obscured by density-driven convective flows. Limited experience during space experiments indicates that above a critical Marangoni number(ratio of surface tension force to viscous force), the flow becomes unsteady and temperature fluctuations in the melt are observed. In addition, a detailesd series of ground and low-gravity experiments have demonstrated that striations due to Marangoni convection are produced in float-zone grown silicon.

  • Brazing (Metals)
CONT

The temperature at which a brazing material starts to melt is known as the Solidus temperature. At the Liquidus temperature the brazing material is completely melted, and this is the minimum temperature at which brazing takes place. The difference between solidus and liquidus is known as the melting range and may be of importance in the selection of the brazing material, particularly as an indication of the rapidity with which the alloy will "freeze" after brazing.

French

On appelle température dite «Solidus» la température à laquelle un matériau de brasage commence à fondre. À la température dite "Liquidus", le matériau de brasage est entièrement fondu et cette température est la température minimale de brasage. L'écart entre la température «Solidus» et la température «Liquidus» est en fait la plage de fusion, et cette plage devient très importante au moment de choisir un matériau de brasage, entre autres, parce qu'elle indique la rapidité de solidification de l'alliage après le brasage.

There are a number of thermal [seaming] methods that can be used on thermoplastic geomembrane materials. Hot air uses a machine consisting of a resistance heater, a blower, and temperature controls to blow between two sheets to actually melt the surfaces. Usually, temperatures greater than 500 °F are required. Immediately following the melting of the surfaces, pressure by rollers is applied.
