Hi friends,
I am working in plastic pipe test lab. I try to explain my problem.
In spiral sewage plastic pipes, ring stiffness is most important parameter. According to the DIN 16961, elasticity modulus of HDPE at 24h (380MPa) and moment of inertia are used to determine ring stiffness value...

Hi Friends,
Could you give some information about this problem. I work on polymer processing and I have a simple test system. This system consist of heated reservoir and a piston. Polymer is filled in reservoir and heated when is melted. then polymer flows through small hole. In this system...

Hi ,
Could you guide me about this problem?
I want to calculate max pressure in the capillary rheometer.And then I will calculate outher diameter of barrel and die for safe.But I can't find true formula for this aim.Max piston load ,barrel diameter die diameter and max-min shear rate values...
Hi all friends,
I need to learn something about finishing.Could you give some information about this sentence ?
" The bore should be finished by techniques known to produce approximately 12rms "
Thanks for your interest

Hi,
Could you give some information that How can I measure die swell diameter without using laser sensor.? Could you advise
an apparatus for this aim?
Thanks a lot
Hi,
I will study with a capillary rheometer for learning rheological properties of some polymers.But I don't know this system very well.I read some article and some books about capillary rheometer.And I didn't understand some point.
For example ,why polymers seems melt fracture properties at...
