Effectively prevent U-bolts from rusting
The coating technology on the surface of fasteners such as U-bolts is generally cold galvanized, which can lead to signs of rust after being used for more than 1 year. Once rusted, it will not only affect the appearance and appearance, but also affect the Its performance has a great impact on the use of the equipment, so in our use, we should pay attention to the following basic conditions to prevent rust.
First, let the surface of the U-bolt dry as much as possible so we can avoid a lot of it.
1. The attachment of dust or other metal material particles, in humid air, the attached condensed water and stainless steel screws, connect the two into a micro-battery, triggering electrochemical behavioral reactions, and the protective film is easily severely damaged, which is called electrochemical Analyze corrosion..
2. The stainless steel U-bolt has adhesion to the surface of organic juice, in the absence of water and oxygen to form an organic acid, the organic acid is a long corrosion on the surface of the metal material.
3. The adhesion of stainless steel U-bolts, alkali and salt-rich surfaces cause local corrosion of students.
4. In some polluted air (such as the atmosphere is rich in a large number of different sulfides, carbon oxides, nitrogen oxides in my country), uncondensed water forms the liquid point of sulfuric acid, nitric acid, and acetic acid, causing students to chemistry structural corrosion.
