New technology realizes “zero emission” of rubber production wastewater

The waste water discharged from the rubber production process can be used to irrigate farmland, raise shrimp and raise fish, and can also be used as a liquid fertilizer. Two invention patents of Professor Wang Xiangqian, a bio-preservation expert, have solved the problem that has plagued the rubber industry for more than 100 years. solve. The test and industrial production of the Jibao Rubber Factory in Zhongxing Town, Chengmai County, Hainan Island showed that the technology realized “zero emission” of rubber production wastewater.

Rubber is an important industrial raw material and an indispensable strategic material. However, for more than 100 years, rubber plants around the world have generally used ammonia water-preserving latex, and then cured with formic acid or sulfuric acid to make dry glue, which not only has toxic side effects on the human body, but also produces a large amount of pollutants in the rubber production process. It has brought tremendous pressure, and it has also caused a decrease in the dry content of rubber and a decline in quality.

Through numerous experiments, Wang Xiangxiang finally developed a successful ammonia-free preservative and natural rubber latex biocuring agent. According to reports, the ammonia-free preservative is a biological preparation compounded by nanotechnology, which acts as a bacteriostatic, bactericidal, moisturizing effect on natural rubber milk, and can increase the wear resistance and toughness of rubber while increasing the dry content of natural rubber. And strength. After being treated with natural rubber, it can be kept at room temperature for one year without deterioration. The natural rubber milk bio-curing agent plays a role in curing, anti-corrosion and bleaching in the rubber production process, and can make the rubber latex cure quickly, does not change color, has increased strength, and has no toxic and side effects.

The industry believes that Wang Xiangqian's two invention patents can completely replace toxic ammonia, formic acid and sulfuric acid in function, but have no toxic side effects, do not pollute the environment, and increase the dry rubber content, which significantly improves the rubber quality. The advent of this technology has important environmental significance and economic value. It is a major breakthrough in the history of rubber production and an epoch-making revolution in the world rubber industry.

It is reported that the technology has obtained invention patents in 2011. After the inventors improved and perfected, industrial production has been realized.
