In this paper,the influence of process on the Lovibon color index of skim rubber was studied. The results showed that,the Lovibon color index of skim rubber reached below 11 when the following process control was implemented: ammonia removal equipment was added in the skim rubber pool,acid mass fraction was controlled in the range of 0.15 to 0.25,antioxidant(sodium metabisulfite)solution with a mass fraction of 0.05 was sprayed in,and 2 more sets of pressure crepe units was added. In addition, the production cost was significantly reduced.
