Process for producing paraffin-containing foam regulators |
摘要 |
A process for producing pourable foam regulator granules containing a defoamer combination of a paraffin wax and a bisamide derived from diamines and carboxylic acids and an inorganic, water-soluble or water-dispersible carrier salt by pelletizing in a granulation mixer with intensive mixing 50 to 100 parts by weight of the inorganic carrier salt optionally with up to 5 parts by weight of an anionic or nonionic cellulose ether, adding 1 to 10 parts by weight of an aqueous alkali metal silicate or polymeric polycarboxylate solution and then adding 10 parts by weight of the defoamer combination heated to a temperature of 70° C. to 180° C.
