Problems solved by technology
[0003] In order to have a good anti-corrosion function, the existing steel bridges usually undergo plastic spraying treatment. The existing plastic spraying process is not perfect enough to form a complete plastic spraying process, which makes the anti-corrosion performance of the bridge poor. Therefore, we put forward a processing method of plastic-steel composite bridge frame and put it into use to solve the above problems

The invention belongs to the technical field of bridge frame plastic spraying, and particularly discloses a machining method of a plastic steel composite bridge frame. The machining method of the plastic steel composite bridge frame comprises the following specific steps that S1, oil removal process operation is carried out on the steel bridge frame; S2, rust removal process operation is carried out on the steel bridge frame; S3, surface adjustment and phosphating process operation are carried out on the steel bridge frame, and a layer of phosphate coating capable of resisting a corrosion andincreasing the adhesive force of a spraying coating is formed on the surface of steel bridge frame; S4, passivation process operation is carried out on the steel bridge frame, and the passivation process can seal holes and seams of the phosphating coating; and S5, plastic spraying process operation and solidifying process operation are carried out on the steel bridge frame. According to the machining method of the plastic steel composite bridge frame, oil removal, rust removal, surface adjustment, phosphating process, passivation process, plastic spraying, solidifying process and other processoperation are carried out on the steel bridge frame, a complete plastic spraying process is formed, and during fixing, the chain speed of a tunnel furnace can be changed according to the thickness ofplastic spraying coating, so that the working efficiency is improved.
Description
technical field [0001] The invention discloses a bridge frame spray technology field, in particular to a processing method of a plastic-steel composite bridge frame. Background technique [0002] The existing steel bridges are divided into trough type, tray type, ladder frame type, grid type and other structures, which are composed of brackets, bracket arms and installation accessories, etc., and can be erected independently or laid on various buildings (structures) And on the bracket of the pipe gallery, it embodies the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. Good focus, high impact strength physical properties. [0003] In order to have a good anti-corrosion function, the existing steel bridges usually undergo plastic spraying treatment. The existing plastic spraying process is not perfect enough to form a complete plastic spraying process, which makes the anti-corrosion performance of the bridge poor. ...
