Firstly, this type of protection is impenetrable. Some workpieces have slender and curved small holes, or narrow and blind holes, which are often difficult to prevent rust even when coated with oil. If vapor phase rust inhibitors are used, rust prevention measures can be easily completed. In fact, vapor phase rust inhibitor is an active rust preventive material. As long as the sealing environment permits and the rust inhibitor is still present, it can continue to maintain the rust preventive state. Unlike rust preventive oil and coatings, coatings that damage the rust preventive function lose it. Therefore, its rust prevention protection period is very long, and it is commonly used as a weapon rust prevention in the military, with a maximum rust prevention period of 12 to 20 years. Its use protection and removal are very convenient. As long as the workpiece is placed together with it and sealed with plastic bags, rust protection is completed. When removing, open the sealing bag and take it out for use. In recent years, for mechanical and electrical products exported from European countries, they often require the use of oil-free rust prevention, as the rust prevention oil ultimately turns into sewage, which can cause pollution to the importing country. Therefore, the use and dosage of vapor phase rust inhibitors will be increasing, and it can be foreseen that in the near future, vapor phase rust inhibitors will become one of the main rust prevention materials for steel.
