Description
Technical Field
The invention belongs to the technical field of keels, and particularly relates to a treatment process of a corrosion-resistant keel.
background
The keel is a building material for supporting a modeling and fixing structure. The keels are of various types and can be divided into wood keels, light steel keels, aluminum alloy keels, steel keels and the like according to different manufacturing materials. The partition board is divided according to the use position and can be divided into a ceiling keel, a vertical wall keel (partition wall keel), a floor keel, a hanging keel and the like. According to different decoration construction processes, bearing keels and non-bearing keels (namely the accessible keels and the inaccessible keels) are arranged. The light steel keel is a decorative material which is very hot in recent years, can be used for suspended ceilings and partition walls, has strong fire resistance, and can be used for making various beautiful models. The existing light steel keel has certain corrosion resistance through hot galvanizing treatment, but in the construction or use process and after repeated expansion and contraction for a long time, the galvanized layer is easy to partially fall off, and the keel is easy to partially corrode.

In order to solve the technical problems, the invention adopts the technical scheme that: a treatment process of a corrosion-resistant keel comprises the following steps:
cutting a substrate, and then stamping by using a stamping machine to form a blank;
Secondly, performing surface treatment on the wool by using a sand blasting machine;
Step three, opening holes;
step four, annealing;
step five, hot galvanizing treatment is carried out after cleaning and hot air blow drying;
and sixthly, performing local plastic spraying treatment on the opening part and the bearing surface of the keel, and polishing the plastic spraying part by using a polishing machine to enable the surfaces of the bearing surface and the opening part to be smooth, so that the corrosion-resistant keel is obtained.
Preferably, the surface roughness of the rough material is not less than 5 microns after the rough material is subjected to surface treatment by a sand blasting machine.
preferably, the annealing temperature is 480 to 500 ℃.
Preferably, the cleaning process includes degreasing with a degreasing agent and repeatedly washing with clean water.
Preferably, after the keel is subjected to hot galvanizing treatment, the thickness of the zinc layer is 15-20 micrometers.
preferably, the thickness of the plastic-sprayed layer after the local plastic-sprayed treatment is between 100 and 200 microns.
The working principle of the invention is as follows: the sand blasting machine is utilized to increase the surface roughness of the keel, the surface area of the keel is increased, and the keel has higher corrosion resistance after hot galvanizing. The position that needs the atress on the fossil fragments carries out local spraying plastics and handles, destroys the galvanizing coat when avoiding panel, screw etc. and fossil fragments contact, guarantees the long-time corrosion-resistant ability of fossil fragments.
The invention has the beneficial effects that: the treatment process of the corrosion-resistant keel can produce the keel with long-time corrosion resistance, has simple treatment process, and can finish the corrosion-resistant treatment of the keel by using common treatment equipment.
