Beyond spray-drying, SuperiorPowders offers extensive value-added possibilities for dry mixing
," added Les Auchincloss, Chairman, Marigot Ltd.
The coagulum produced by such wet mixing step, with or without intermediate processing steps, is then mixed with additional elastomer in a dry mixing
step to form the elastomer composite.
Within the system, ingredients are pre-batched into weight scales and after a short period of dry mixing
, the sensor measures moisture content and sand temperature.
Excellent distributive mixing, in which the distribution of the carbon black in the polymer matrix is much more uniform than in dry mixing
It offers fluid bed drying, spray coating, spray granulation and dry mixing
as well as providing secure product handling and containment; variable control of process airflow, temperature and liquid addition; and has interchangeable product containers.
CEC mixing was first carried out under the same conditions and formulations as in convention al dry mixing
(CEC 1 and CEC 2).
The use of the Buna SL 18 BMB in conjunction with BR BMBs can lead to significant mixing time savings relative to conventional dry mixing
, according to the company.
The standard method for compounding elastomers, referred to as dry mixing, is to combine dry, baled solid rubber, carbon black (CB) and other ingredients in an internal mixer.
This proprietary technology represents a breakthrough versus conventional dry mixing of NR/CB compounds.
For those willing to make the investment, dry mixing silica is still an option.
We believe our wet masterbatch technique offers flexibility to utilize many types of silica including those that cannot be satisfactorily incorporated using dry mixing techniques but which potentially have superior compound properties.
Compounds using WMB were prepared by the two stage mixing method, while dry mixing
consisted of three stages.
