The rust prevention method is to take preventive measures against the causes of metal corrosion. Reminder: Since metal corrosion is caused by factors such as humidity, high temperature, oxygen, sulfur dioxide, chloride, dust, etc., rust prevention should avoid or slow down the metal corrosion caused by these factors.
The current rust prevention methods used include: adding certain elements during metal smelting to improve the metal's ability to resist external medium erosion; Perform corrosion resistant surface treatment on metal products to form a surface conversion layer or add a surface coating; Cathodic protection refers to the use of rust inhibitors, vapor phase corrosion inhibitors, peelable plastics, sealing, and other methods to temporarily isolate the metal surface from the external environment (belonging to temporary rust prevention method 1, which can also remove these rust prevention materials smoothly during the use of metal products. This method has a rust prevention period of several months to several years and is widely used.
