Used in the manufacture of emulsion rubber waste of sugar manufacture - molasses

Currently, much attention is paid to development, allowing use of waste and by-products formed during certain manufacturing processes. This allows you to either reduce or completely eliminate the use of valuable and expensive raw materials. The use of this raw material in the production of synthetic rubber will not only reduce the cost of coagulation and acidifying agents, but also to improve the environmental situation. Featured in some cases effective coalescing agents based on polymeric quaternary ammonium salts (PCHSA) have a high coagulating power, and hence low consumption of the allocation of the rubber latex (3-5 kg0t-1 rubber). Scarcity and high cost of these drugs leads to higher prices resulting rubber. Furthermore it is known that the application requires keeping PCHSA sufficiently precise dosage administered substances by the action of a latex, owing to the high capacity of the antiseptic may lead to discharge into natural waters polluted waters. However, using as the coagulating agent departing sugar production - molasses solves a number of problematic steps in the production of synthetic rubber. First, a well-studied effective coagulation effect of different nitrogen derivatives relating to cationic surfactants. In freshly prepared solutions of molasses contained about 9 wt%, and this value increases significantly during enzymatic fermentation. Secondly, highly acidic environment of aqueous solutions of molasses after storage can allow their use in addition to or instead of the sulfuric acid used in large amounts (up to 15 kg m-1 rubber) technology selection tests carried found that vulcanizates derived from rubber samples isolated molasses, consistent with the requirements and were similar to control samples prepared from the latex using sodium chloride.
