A METHOD FOR COAGULATION OF RUBBER LATEX

摘要

The present invention deals with an alternate method of rubber latex coagulation that can be used to produce rubber for rubber goods from stabilized or un-stabilized rubber latex, having quality at par with the commercial rubber in an environmentally benign, less chemical intensive and economic way. The presented route can be used to coagulate rubber in a controlled fashion directly on desired forms for various rubber goods using electrostatic charge generated from renewable and non-renewable power source. The invention presents a systematic study to define the control variables and governing relationship of the control parameters with respect to rubber coagulation/mass of rubber coagulated as shown in (A) of Figure 5 (B). The applied potential, coulomb transport rate (current), time, ionic strength (salt concentration in latex) and rubber content of the latex are the variables/process parameter defined to control rubber coagulation for rubber latex with dry rubber content between less than 4% to greater than 24% as shown in (B) of Figure 7.
