Description
Technical Field
The invention relates to the field of galvanized pipe making liquid, in particular to environment-friendly pipe making liquid friendly to a galvanized layer and a preparation method thereof.
Background
Galvanization is the coating of metal products by immersing them in a bath of molten zinc. Galvanization is suitable for steel products because molten zinc reacts with the steel to form a protective seal on the metal. Galvanization is less costly than many other finishing processes and has a long service life. One of the main benefits of galvanization is that if the metal is damaged, the remaining areas remain protected, so that less damage is not needed for repair.
Galvanization is a process in which a protective layer is immersed only once to protect the product. Other coatings require painting or spraying, which takes more time. The drying process of galvanization is also faster, requiring less time, while other coatings require more time.
The pipe making liquid has the functions of lubrication, cooling, cleaning and rust prevention in the steel plate processing process. The iron and steel plays a great role in modern life, is an important raw material for production and life, and is an important support of national economy. At present, the Chinese steel has the characteristics of great productivity, and the steel plate is easy to corrode and rust, influences the quality of products and causes economic loss due to contact with moisture and oxygen in the air and electrolyte in a processing medium in the processes of processing, placing and transporting. Therefore, the research of the rust prevention technology is profound.
Galvanized pipe making liquid is generally composed of an antirust agent, a pH regulator, a metal corrosion inhibitor, an antibacterial additive, a lubricating additive, an anti-hard water additive, a sedimentation agent, water and the like. The existing rust-proof additives include chromates, silicates, nitrites, borates, esters and the like. Chromates are good rust inhibitors, but are prone to failure, and are harmful to humans and the environment, and have been disabled for a long time. Silicate has limited rust-proof effect and is easy to scale for a long time. Nitrite has good rust resistance, but is easy to crystallize and separate out to form white spots, and is a cancerogenic substance which is harmful to human bodies and gradually exits from industrial production.
