Application method of foldable trolley for transporting environment-friendly phosphatizing liquid

Abstract

The invention relates to an application method of a foldable trolley for transporting environment-friendly phosphatizing liquid, and belongs to the technical field of environmental protection. According to the main technical scheme, the application method is characterized in that when an upper layer plate A, an upper layer plate B and a lower layer plate are placed horizontally, a hook A is hung on a foldable side plate B, a hook B is suspended, an overhead hook hooks the edge of a base at the moment, and an environment-friendly phosphatizing liquid box is placed on the upper layer plate A, the upper layer plate B and the lower layer plate, transportation can be performed by pushing the trolley; when the upper layer plate A, the upper layer plate B and the lower layer plate are overturnedby 90 degrees, the hook B is hung on the foldable side plate A, the hook A is suspended, and inward acting force is applied to the foldable side plate A and the foldable side plate B in order that thefoldable side plate A and the foldable side plate B are folded along a slideway inwards till the two foldable side plates are pressed against the edge of the base, so that folding can be finished. The foldable trolley is simple in structure; the upper layer plate and the lower layer plate can be assembled for use according to practical requirements; the foldable trolley can be taken as a transportation device as well as an ordinary shelf, so that high practicability is achieved; the application method is simple, and high operability is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for using a folding trolley for transporting an environmentally friendly phosphating solution. Background technique [0002] Phosphating refers to the process in which metal parts undergo chemical reactions, electrochemical reactions, etc. in phosphate solutions to form an insoluble phosphating film on the metal surface. As the bottom layer of the coating or the protective layer of the metal surface, the phosphating film can significantly improve the adhesion, corrosion resistance and protective performance of the coating, and is widely used in automobiles, home appliances, machinery, military and other industries. [0003] When the factory produces large quantities of phosphating solution, it generally uses a larger box, and the shelves used for storage are mostly made of traditional multiple steel plates, which cannot be moved or adjusted according to ...

[0003] When the factory produces large quantities of phosphating solution, it generally uses a larger box, and the shelves used for storage are mostly made of traditional multiple steel plates, which cannot be moved or adjusted according to actual production needs. At the same time, storage, Due to the large volume and weight of the box during transportation, it takes a lot of manpower and physical strength
