Abstract

The invention discloses a method for extracting latex by an extremely strong electric field roller pole. The method comprises the following steps: feeding the latex into an extremely strong electric field roller electrode electrogenerated extraction device from a latex inlet in one side; adjusting the direct-current voltage and the distance between the positive electrode roller and the negative electrode tank to form an extremely strong electric field, extracting latex through a plurality of positive and negative electrode cells to obtain clear liquid and rubber sheets, continuously introducing the rubber sheets condensed on the positive electrode roller into a cleaning device through a traction device for cleaning, drying the rubber sheets to constant weight through a drying device, and packaging the rubber sheets to obtain finished rubber. The method is simple in process, different from a traditional flocculation process and a uniform electric field extraction device, free of a flocculation process, environmentally friendly and capable of saving cost, rubber components obtained through flocculation are completely reserved, the performance of the rubber product is excellent, few process human influence factors exist, the product quality is stable, energy consumption is low, efficiency is high, and continuous industrial production is easy to achieve.

Description

technical field [0001] The invention relates to a method for extracting latex with a roller pole with an extremely strong electric field, which is different from the traditional rubber flocculation method and a uniform electric field extraction device. Or the key problems such as long bioflocculation process cycle and difficult waste glue treatment. The method has low energy consumption and higher efficiency than ordinary uniform electric field extraction devices, and the obtained rubber is mainly used in various rubber products, including rubber for automobile tires, rubber filaments, latex products, and the like. Background technique [0002] Rubber is an indispensable raw material in the industry, and the development of the automobile industry has also stimulated the domestic demand of my country's rubber industry. The coagulation of latex has an important impact on the quality of rubber, but the acid flocculation process commonly used now requires the use of flocculants...
