1. Matters needing attention in the use of vapor phase antirust film
Vapor phase antirust packaging is an excellent new antirust packaging technology. The application of vapor phase antirust film can greatly extend the storage period of metal products, benefit the environment and reduce a variety. In order to give full play to the advantages of the anti-rust film, the production cost is low. Vapor phase anti-rust film is highly competitive in the field of anti-rust packaging, and its development prospects promote the development of anti-rust film. In the application of anti-rust film, the following aspects must be paid attention to. Nanjing Sumino Seiko professional film production equipment.
1. Surface cleaning of metal products
Metal products should be cleaned (washed) and dried before anti-rust packaging to ensure the surface is clean; during the packaging process, it is forbidden to directly touch the metal with hands to prevent the presence of hand sweat or moisture, which will affect the protective effect of the anti-rust agent on the metal parts , resulting in corrosion of the metal surface.
2. There should be no spacer between metal and metal
There should be no spacer between the vapor phase antirust packaging material and the metal, and the distance between the packaging material and the metal surface should not be too large, preferably not more than 30cm, so as to facilitate the accumulation of vapor phase antirust agent vapor on the surface of the metal parts. Thus showing a reliable anti-rust effect.
3. The relative humidity in the package should not be too high
The relative humidity in the package should not be too high, generally not more than 85%, because the anti-rust film may dissolve and become invalid due to long-term contact with moisture. desiccant.
4. The space inside the anti-rust film bag should be relatively sealed
Since the antirust effect of the antirust film comes from the existence of vapor phase corrosion inhibitor vapor inside the package, in order to prevent the large amount of vapor phase corrosion inhibitor from escaping and reduce the antirust effect and prolong the antirust time, when using the antirust film, the antirust film bag The space inside should be relatively sealed.
5. Guarantee the integrity of the packaging
During the transportation and storage of vapor phase anti-rust film, care should be taken to keep the packaging intact and store in a cool and dry warehouse (not in an environment above 65¡ãC, but below 0¡ãC), avoid direct sunlight, and store in a cool and dry warehouse. Avoid contact with acid, alkali, salt and other pollutants during the process.
6. Variety anti-rust pertinence
The vapor phase antirust film relies on the volatilization of the vapor phase corrosion inhibitor to produce the antirust effect. The antirust effect of the vapor phase corrosion inhibitor has a certain scope of application. Therefore, the corresponding vapor phase antirust film should be selected according to the metal material to be protected. rust film.
2. Current situation and prospect of vapor phase antirust film
Vapor-phase antirust plastic film has a wide range of applications, and can be used for antirust packaging of steel, cast iron, copper, brass, bronze, aluminum, galvanized sheet, tinplate, silicon steel sheet and other metals and various forms of industrial products. Vapor phase antirust film can meet the packaging of metal products of different specifications, such as machine parts, components and finished products, metal tools and spare components, etc., mechanical parts as small as a few millimeters, as large as the entire aircraft can be packaged with vapor phase antirust film . The fields of use include: automobile industry, shipbuilding field, aircraft field, light machinery field, precision machinery field, electrical and electronic field, metal smelting and processing field, military field and other fields where metal is applied. At present, vapor phase antirust paper is the most widely used typical vapor phase antirust packaging material in the world. Rusty paper is made of paper/plastic composite material as the carrier, and this kind of paper-plastic composite waste packaging, due to the constraints of separation technology and separation cost, is not easy to be recycled, nor can it be naturally degraded. It can only be incinerated, which not only causes waste of resources, but also causes environmental pollution. At the end of the 1990s, many countries and regions have begun to prohibit or restrict the use of paper/plastic composite materials. It can be expected that the strong driving force of environmental protection and rational utilization of resources will accelerate the transformation of vapor phase antirust packaging materials from paper/plastic products. The conversion to all-plastic vapor phase anti-rust plastic film, all-plastic vapor phase anti-rust plastic film will gradually become the mainstream product of vapor phase anti-rust packaging materials.
