Abstract：The viscose production equipment will be affected by the temperature and humidity environment in the working process， which leads to the large area corrosion phenomenon of viscose production equipment. In order to avoid large area corrosion of viscose production equipment， a corrosion protection method of viscose production equipment based on SEBF coating technology is proposed. According to the properties of SEBF series anti-corrosion coatings， the SEBF coating process was designed. Through analyzing the specific steps of SEBF coating of viscose production equipment， SEBF coating of viscose production equipment was completed. The corrosion data of viscose production equipment was analyzed and processed by using the probability distribution involved in the corrosion of viscose production equipment. Through the expression of Gembel distribution， the density function of the corrosion of viscose fiber production equipment is established， combined with the relationship between the reversal period and the position of the integral probability， the corrosion evaluation model of viscose fiber production equipment is established， the equation of state of the sacrificial anode cathodic protection method is solved by numerical methods. According to the characteristics of sacrificial anode protection method， the corrosion protection of viscose fiber production equipment is calculated by finite element method， and the corrosion protection of viscose fiber production equipment is realized. The experimental results show that the corrosion protection method of viscose fiber production equipment based on SEBF coating technology has high performance in three aspects of longest working time， work efficiency and maintenance cost， which can avoid large area corrosion of viscose production equipment.
