Guarkernmehl wird aus dem Endosperm der Guarpflanze, Cyamopsis tetragonolobus, gewonnen. Sie gehört zur Familie der Leguminosen. Die sogenannte Buschbohne wird vor allem in Indien und Pakistan von Juli bis Dezember angebaut. Qualität, Verfügbarkeit und Preise sind jedoch sehr stark vom Monsun in diesem Zeitraum abhängig. Rajasthan, Gujarat und Haryana gehören zu den wichtigsten Anbauregionen. Die trockenen Guarbohnen werden gedroschen, um die Guarkerne (seeds) aus der Bohne zu gewinnen. Mit einem weiteren Schritt wird aus dem Kern durch Trennung von Schale und Keim das Hydrokolloid Guar (Split) hergestellt.

Dispergator for sandwich panel production lines Mixing concept Because of changes in regulations on additives and the complexity of for-mulations, items in the Polyol blend viscosities were varied and are very difficult miscible or even immiscible. The result is a foam very difficult to implement, surfaces in contact with the plate full of bubbles, adhesion problems, shrinkage problems, bubbles, … To circumvent the lack of miscibility of the components we have developed two elements allowing a dispersion of additives and the gas into very small particles homogenously distributed in the Polyol. Therefore, when the Polyol is mixed in the mixing-head with Isocyanate, additives are much more reactive and there is no concentration of gas or random foaming agents that create bubbles surface states or « potato fields. ». The disperser is to this day an essential element of the production units of polyurethane foams and have a great effect on PIR. It is available as low pressure (air...
