Application method of metal spraying nozzle corrosion-prevention device

Abstract

The invention provides an application method of a metal spraying nozzle corrosion-prevention device and belongs to the technical field of metal corrosion prevention. The application method is characterized by comprising the following steps: preparing cationic polyacrylamide PAM into a 0.1 to 0.30 percent water solution to prepare a No. 1 washing solution; adding Lonza polyaminopropyl biguanide toprepare a 10 to 21 percent water solution used as a No. 2 washing solution; adding glycerol emulsion to prepare a 0.05 to 0.5 percent water solution used as a No. 3 washing solution; gradually fully filling into a whole liquid path system and spraying out from a spraying nozzle, so as to discharge water molecules and water which are free in the whole liquid path system or fuse into a corrosion-prevention clearing solution; and forming one layer of a corrosion-prevention clearing solution thin film on a contact part of the metal spraying nozzle and liquid, so as to prevent electrochemical corrosion conditions from being formed by the spraying nozzle and a water through hole of the spraying nozzle and realize corrosion prevention of the metal spraying nozzle and the water through hole of themetal spraying nozzle. The water through hole of the metal spraying nozzle keeps a smooth state all the time, so that the problem that the dry mist dust-inhibition metal spraying nozzle cannot work normally due to corrosion sis also solved.

Description

technical field [0001] The present invention relates to an application method of a metal nozzle anti-corrosion device, which belongs to the technical field of metal anti-corrosion, specifically a method of preparing a 0.1% to 0.30% aqueous solution of cationic polyacrylamide PAM as the No. 1 cleaning solution, adding Lonza polyaminopropyl biguanide is prepared into a 10%--21% aqueous solution as the No. 2 cleaning solution, and the glycerin emulsion is added to prepare a 0.05%--5% aqueous solution as the No. 3 cleaning solution. And it is sprayed from the nozzle, so that the water molecules and air dissociated in the entire liquid system are discharged or fused into the anti-corrosion cleaning liquid, and a layer of anti-corrosion cleaning liquid film is formed on the contact part between the metal nozzle and the liquid, so that the nozzle and the nozzle communicate The water hole cannot form electrochemical corrosion conditions, and realizes the anti-corrosion of the metal no...

Problems solved by technology

[0003] The purpose of the application method of an anti-corrosion device for metal nozzles of the present invention is to solve the existing and unsolvable problems in the above-mentioned prior art, thereby disclosing a simple and reliable anti-corrosion cleaning method composed of silicone oil emulsification and water melting in proportion Liquid, the anti-corrosion cleaning liquid is filled into the entire liquid circuit system and sprayed from the nozzle, so that the anti-corrosion cleaning liquid makes the water molecules and air dissociated in the entire liquid circuit system discharge or fuse into the antifreeze cleaning liquid. The metal nozzle and the liquid contact part form a layer of anti-corrosion cleaning liquid film, so that the nozzle and the nozzle water hole can not form electrochemical corrosion conditions, and realize the anti-corrosion of the metal nozzle and the corrosion prevention of the metal nozzle water hole. The water hole has been kept unobstructed, and the air valve and the liquid valve are activated to realize the normal gas mist dust suppression work. The technical feature of the device is the anti-corrosion cleaning liquid in the anti-corrosion device through the additional dry fog dust suppression metal nozzle. Flow through the outdoor liquid circuit system and flow out from the nozzle, so that the anti-corrosion cleaning liquid makes the water molecules and air free in the entire liquid circuit system discharge or merge into the anti-corrosion cleaning liquid, forming a layer on the contact part of the metal nozzle and the liquid Anti-corrosion cleaning liquid film, so that the nozzle and the nozzle water hole can not form electrochemical corrosion conditions, and the anti-corrosion of the metal nozzle and the corrosion prevention of the metal nozzle water hole are realized, and the metal nozzle water hole is kept unobstructed, so that It solves the industry bottleneck problem of anti-corrosion of nozzles and nozzle water holes when the spraying system suspends the spraying work, so as to avoid the occurrence of vicious events caused by nozzle corrosion failure and liquid circuit out of control
