Dear All,
After mixing some rubber batches with isoprene elastomere formulation there missing ts2 on the Rheo testing?
After remmiling there are ts2 but ts1 is much lower.
What is the main cause that Ts2 is missing?
Thanks in advance,

Dear all,
Pipelines SS304L will be installed in our plant (classical welding not orbital) for transportation of liquid raw materials ( mineral oils, silicon oils.. ) . So how it should be cleanend after installation because it must be completely clean an dry? Do we need cleaning with...
Helo JIM317,
Thank you for the answer.
I'm on the holliday now, but after I'll check reo curves and spec gravity .
What does it mean "worn out mixer"?
Thank you for the lot off information and of course for your time.
Regards,
JIM317 (Chemical), can you please describe the"If you are mixing a masterbatch + final the accuracy of curative weighings can have an effect".
We have good hardnes when we mix the whole batch in the open mill , but we have 2 shores lower hardnes when we mix it in the internall mixer? And we...
Hello,
We have problem with rubber hardness it is sometimes higher and sometimes lower with same raw materials, so could somebody tell me how can we encrease hardness during mixing step in our production. Does the odrder of adding raw matterials has some infulance of the hardness or temperature...

We are small producers of biodiesel and we want to increase our production capacity to 20000 tons per year. One of the problems is slow separation of methylester and glycerin phase. We have horizontal gravity separators .Does anybody know what kind of coalescing mediums are being used for the...
Hello, 25362.
4. The reaction is between potassium hydroxide( 85%)- 64 kg and methanol (99,5%)-1600 lit .
5.Reaction is exothermic ,don't know how much enthalpy is realised.
6. Yes I plan to keep reaction mixture at 50 deg C by refluxing and cooling reaction mixture.
7. Water is present in...
Hi ,I want to size vertical condenser for methanol vapours above the batch reactor of 2 m3 volume. Reaction time is 1 hour, temperature is 50 C, and the pressure is 1 bar. Problem for me is to determine the quantity of methanol that evaporates in 1 hour.
Thanks.

Thank you both for your answers. There is very usefull compressed air leak rate table on http://www.cleandryair.com/LeakRateTable.htm
TD2K could you tell me, in the equation
W = 1891*do^2*Y*C*(dP*p)^0.5 , in what units is W?
Regards.
I want to calculate air leakage out of the pressuresed air pipeline through the hole . How can I calculate air flow as a function of pressure in the pipe and as the function of the diametar of the hole ? For example: we have hole diametar=6 mm and pressure= 6 bar? It is the ambient...
Does anybody has experience with the application of the "ION SCALE BUSTER" in the cooling towers recilculation water systems and heating circulation water systems .It is the device for decreasing of scaling in the system and for corrosion protection.
Thank you.

Thank you all for these informations and links. Because I have to storage NaOH solution at 20 C I will take stainless steel material.I do not need high temperatures so I do not need Ni .
Regards.
Dear colleagues,
Does anybody know's what material I can use for storage of 70 % solution of NaOH at room temperature ?
Thank you.
