【Abstract】 Sulfurization that is the reaction of benzene with sulfuric acid to produce benzene sulfonic acid is very important in the process of the production of washing powder. The precision of pH value of products affects the quality of washing powder. The AT90S8535 single chip control system is used to control the pH value of sulfurization. The control method, the hardware composition and the accomplishment of the software of the system are introduced.更多还原
