| titleOfInvention | A reducing boron sulfate rust remover |
| abstract | The application provides a reducing boron sulfate rust remover. The preparation steps are: (1) heating 40-80 parts of nonylphenol or nonylphenol polyoxyethylene ether to 120-140°C, and then slowly adding 1- 10 parts of boric acid, react for 80 to 120 minutes after the addition; (2) cool down to 70 to 80 ° C, add 1 to 5 parts of adjuvants, and naturally cool down to room temperature; (3) slowly add 0.5 to 4 parts of S under vacuum O 3 or SO 3 , stir while adding, and after adding, the temperature is raised to 60-70° C., and the reaction is performed for 80-120 minutes; (4) the temperature is lowered to below 50° C., 1-5 parts of auxiliary agents are added, and the reaction is performed for 80-120 minutes, Then naturally lower the temperature below 30°C; (5) add 2-6 parts of reducing agent and stir evenly. This rust remover has a quick and thorough effect on the removal of oxide scale. |
