How to achieve long-term rust prevention by water-based rust inhibitor

After the metal workpiece is processed, it is required to carry out anti-rust treatment on the metal surface. It is called a rust proof package. According to the different metal anti-rust materials, it is divided into the following metal treatment methods for metal anti-rust agents.

1. Water-based rust inhibitor, including water-soluble rust inhibitor, rust-proof cutting fluid, water-based rust inhibitor, rust-proof water, water-based rust-proof liquid, water-based rust-proof oil

2, oily rust inhibitor, including thin layer anti-rust oil, quick-drying anti-rust oil, electroplating anti-rust oil, hard film anti-rust oil, metal anti-rust oil, replacement anti-rust oil

3, gas phase rust inhibitor, including vci gas phase rust inhibitor, vci gas phase rust inhibitor, vci gas phase antirust oil, vci gas phase antirust paper, vci gas phase antirust film, vci gas phase antirust sponge, VCI gas phase antirust powder, etc.

Metal rust inhibitor is a composite. Whether it is water-based rust inhibitor, oil rust inhibitor or gas phase rust inhibitor, the composition of metal rust inhibitor generally contains three major components, different types and functions of metal corrosion inhibition. The agent, the auxiliary additive and the carrier form a metal rust inhibitor. For example, vci multi-metal vapor phase anti-rust paper is a multi-metal anti-rust agent solvent soaked into the anti-rust base paper; metal anti-rust oil is an oily metal composed of petroleum sulfonate, lead naphthenate and base oil. Rust inhibitor.

For the anti-rust of fine metal parts, professional anti-rust oil manufacturers, in the conditions of the price of anti-rust oil, the product design of metal anti-rust agent will be carried out from the following four specifications.

First, the multi-metal anti-rust: the anti-rust effect on the black metal is very good, but it does not corrode the copper non-ferrous metal and acts as a copper anti-rust agent.

Secondly, the moisture is good: not only the structure is simple and the surface area is easy to operate, but the structure is complicated, the hole or the inner cavity is also simply coated, ensuring that the metal rust preventive agent can enter usefully and adhere to form a certain anti-rust film layer.

Then the rust-proof period: after the metal rust-proof treatment, it is the short-term process rust prevention, or the long-term rust prevention with short-term lubrication at the same time.

Then satisfied with the subsequent process of the metal product: the need to consider whether the metal anti-rust treatment affects subsequent welding, cleaning, electroplating, etc. For example, the rust inhibitor contained in the rust preventive agent cannot be easily removed by the plating cleaning agent, which may affect the adhesion of the plating layer or the lacquer coating, resulting in subsequent plating or paint quality defects.
