All metal products are faced with corrosion problems. People have been struggling for anticorrosion, and have found various anticorrosion methods, such as electroplating, dip coating, vacuum packaging, paint, and oiling. But? F, some metal products are not suitable for the above method, so people have studied the use of gas phase rust prevention methods. For this, the United States, Japan, and the former Soviet Union have studied for more than 20 years. Gas-phase anti-rust plastic packaging has become popular in the world in the past five years. However, there are very few domestic researches that have succeeded in commercial production. Gas-phase anti-rust plastic packaging is an emerging technology, which will replace anti-rust grease and anti-rust paper, and has a wide range of uses. Such as the storage of weapons, precision instruments, electronic instruments, electronic devices, auto parts, hardware tools, bearings, lamps, etc., may say goodbye to the oiled era. Its principle is that the gas phase rust inhibitor can be directly vaporized (sublimated) at normal temperature and pressure, and reach a saturated vapor state in a closed environment. Its molecules adsorb to the metal surface to form a dense and transparent protective film to prevent the metal from being corroded. Moreover, the antiseptic molecule is a gas, and it is permeable. No matter how complicated the shape of the metal product is, the antirust effect can be obtained everywhere. The gas-phase antirust plastic film is the product of the combination of the gas-phase antirust agent and the plastic. In the description process, it was found that there are many varieties of gas phase rust inhibitors, and they have targeted effects on different metals. In the screening process, toxic varieties and nitrite drugs are avoided, which is both efficient and non-toxic. Since most metal products on the market are metal components, it is necessary to effectively prevent rust on a variety of metals. Good compounding is the key, and it can be well fused with plastic, so that the gas phase rust inhibitor is slowly released and extended. Anti-rust period. In the plastic bag made by composite method, the outer layer of high-barrier nylon material makes the gas-phase rust inhibitor can only be released into the bag and rarely diffuses outside the bag to prevent the loss.
