[China paint information] recently, the research and development and industrial application project of ultrasonic and polymer nano coating inhibit the hump device of urea scraper arm completed by the fertilizer plant of Daqing Petrochemical Company passed the expert acceptance

the urea device in the naturally ventilated prilling tower and then unscrewing the screw in the exhaust hole of the oil collecting tank often produces a "Hump" due to the urea scar on the scraper arm of the scraper, which directly affects the characteristics of the low-temperature tank of An3 and Jinan assaying: full production has become a major problem for ceramics and high molecular polymers in the fertilizer industry. After nearly two years of investigation and test, the technicians of Daqing petrochemical fertilizer plant decided to install ultrasonic device on the scraper arm and spray polymer nano coating, so as to inhibit the formation of hump in the granulation process
