1. The complexity degree of the rust removal parts is different. For products containing plastic and rubber parts, a more mild neutral rust remover should be chosen.

2. Different rust removal metal substrate, for rust removal, you can choose the general neutral rust removal agent, of course, you need to choose to be able to remove deep rust, no flash rust and long-term rust prevention effect is better. For other inert metals, a neutral rust remover of the ENIENT special formula is required.

3. Operation time. Fast operation is the focus of rust removal. ENIENT® 5 min fast neutral rust remover can meet this demand.

Neutral rust remover is a water-based rust removal agent, safe without stimulation, no pungent smell, biodegradable, green environmental protection. The most important thing is that the iron and steel matrix does not produce corrosion and hydrogen brittle phenomenon, does not affect the product material. Neutral rust removal after a special formula of improvement, the same pickling or alkaline rust removal agent rust removal speed, and the effect is better.

Acid rust removal agent, as the name suggests, of course, is to use the common strong acid (sulfuric acid, hydrochloric acid, nitric acid, etc.) for rust removal. Its principle is to use the oxidation and corrosion of acid metal oxides, corrosion dissolved to achieve the purpose of rust removal.

Neutral rust remover, namely the PH value between 6.5 and 7.5, is called neutral, its rust removal principle is only with the metal surface of the oxide: iron oxide and iron dioxide reaction, not reaction with iron atoms. So as to be safe and accurate removal of rust.

Ruust converter rust converter working principle is to let the converter in contact with the rust layer, the chemical reaction occurs, and eventually will form a layer of black anti-rust paint layer. This method will change the metal state and the paint will off easily.

The first kind: pickling. Spickling is the traditional use of nitric acid, sulfuric acid, hydrochloric acid and other strong acids, after a certain proportion of dilution, pickling, but easy to cause acid fog, environmental protection is not standard, and will cause a large degree of corrosion to the metal.

The second kind: neutral water base rust removal. ENIENT's neutral rust remover, which can solve the acid fog and corrosion problems. And the rust removal process is very fast, for the heavy rust only need to soak for a few minutes.

Copper metal, if it does not do any surface protection treatment, in the natural state is very easy to oxidation and rust, if placed in high temperature or humidity for a long time, the oxidation and rust will be more serious. Oxoxidized copper activity is also low, and ENIENT EC0132 with higher activity is recommended. The PH value of 6.2 to 7.2 is neutral and not corrosive to a variety of metals (including copper, aluminum, magnesium, steel), plastics and rubber. It does not contain oil ingredients, but uses a water-based formula, so the discharge is simple and environmentally friendly.

Aluminum metal, if placed in a salt fog environment or in a relatively humid environment, will also rust for a long time. Therefore, the rust removal treatment and the passivation process are needed. If rust is found on the aluminum surface, rust removal maintenance should be carried out immediately to prevent corrosion aggravation. And regenerate the oxide layer to prevent subsequent rust. Aluminum rust can use ENIENT of rust removal agent to rust removal and maintenance.

Iron is a more active metal, the general rust removal process is also relatively simple and crude, the use of sandblasting or pickling process, all have a greater degree of damage to the iron. It is recommended to use neutral rust remover, fast speed, and no corrosion damage to the iron surface, the surface after rust removal surface is more smooth and delicate, and has a certain rust prevention function, the surface without oil can be directly painted or coating.

To remove the rust of a bicycle, it is necessary to ensure that it does not damage the bicycle itself, but also simple operation, non-professionals can quickly get started, and rust removal is fast, does not harm the health of users, and it is best to be environmental protection and emissions.These can be solved with ENIENT quick neutral rust remover.
