Abstract
The utility model discloses an inner zinc-plating and outer phosphatizing fuel tank which comprises a fuel tank. A zinc-plating layer is arranged on the inner wall of the fuel tank in a coating mode. A phosphatizing layer is arranged on the outer wall of the fuel tank in a coating mode. Due to the fact that the inner wall of the fuel tank is provided with a zinc-plating layer and the outer wall of the fuel tank is provided with a phosphatizing layer, the inner zinc-plating and outer phosphatizing fuel tank can satisfy the different corrosion prevention requirements of the inner wall of the fuel tank and the outer wall of the fuel tank in a targeted mode. The inner zinc-plating and outer phosphatizing fuel tank has the advantages of being good in corrosion prevention, simple in fabrication processing, and low in cost.
Description
Technical field
The utility model relates to a kind of fuel tank, in particular a kind of interior zinc-plated outer phosphatization fuel tank.
Background technology
The fuel tank operating mode that construction machinery and equipment is used is generally relatively poor, may face more abominable environment for use, and this antiseptic property to fuel tank has proposed higher requirement.If by improving the material of fuel tank, then can increase productive costs, simultaneously because the requirement for anticorrosion of fuel tank inside and outside wall is different, adopt same material to make, do not satisfy different demands.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of interior zinc-plated outer phosphatization fuel tank is provided, and coats respectively zinc coating and phosphate coating by the inside and outside wall at fuel tank and realizes anticorrosion.
The utility model is achieved through the following technical solutions, and the utility model comprises fuel tank, and the inwall of described fuel tank coats zinc coating is set, and the outer wall of described fuel tank coats phosphate coating is set.
As one of optimal way of the present utility model, the thickness of described zinc coating is 8～25um.
As one of optimal way of the present utility model, the thickness of described phosphate coating is 5～8um.
The utility model has the following advantages compared to existing technology: the utility model can be accomplished the different requirement for anticorrosion of fuel tank inner and outer wall targetedly by processing in the zinc-plated processing of the inwall of fuel tank and outer wall phosphatization.Favorable anti-corrosion effect, PROCESS FOR TREATMENT is simple, cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The below elaborates to embodiment of the present utility model; the present embodiment is implemented under take technical solutions of the utility model as prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, the present embodiment comprises fuel tank 1, and the inwall of described fuel tank 1 coats the zinc coating 11 that thickness is 10um is set, and the outer wall of described fuel tank 1 coats the phosphate coating 12 that thickness is 7 um is set.
Zinc coating 11 is as the inner wall anti-corrosive layer, and corrosion stability reached salt spray test more than 420 hours; Phosphate coating 12 can the outer field antiseptic power of large increase as the bonding coat between outside preservative coat and the workpiece.The salt spray resistance experiment of phosphate coating 12 can reach more than 1000 hours.
