Abstract

The invention provides a shelf surface treatment method and belongs to the technical field of storage equipment. The shelf surface treatment method includes steps of removing oil stain, dust and rust on the surface of a workpiece, generating a phosphate coating layer anticorrosive and capable of increasing adhesion force of a spraying layer on the surface of the workpiece, uniformly spraying powder coating on the surface of the workpiece, spraying the position easy to generate electrostatic screening by a high-performance electrostatic plastic spraying machine, pushing the sprayed workpiece into a curing furnace, heating to the temperature of 185 DEG C, preserving heat for 15 minutes, opening the furnace and cooling to obtain a finished product. The shelf surface treatment method aims to protect a shelf and prolong service life of the shelf in a warehouse, in particular to a heavy shelf, wear is high at ordinary time, steel is easy to oxide by the air, an oxide layer is adhered on the surface, and oxides on the surface of the shell are removed, in all, the purpose of acid pickling and phosphatizing is realized.

Description

The method of shelf surface process

?

Technical field

The invention belongs to memory device technical field, particularly relate to a kind of method of shelf surface process.

Background technology

Shelf are the safedeposits being used for depositing work piece specially.Shelf are little in warehouse occupies very important status, along with increasing considerably of logistics capacity, is the modern management of Implementation repository, improves the function in warehouse, not only require that pallet quantity is many, and requirement has multi-functional, and can realize mechanization, automation requirement.

Shelf proportion in the gross investment of storage facilities is comparatively large, and pool consumption steel are maximum, affects greatly the operating mode in warehouse.Therefore choose reasonable designs economic shelf is relatively very important.Under the condition ensureing shelf intensity, rigidity and resistance to overturning, the weight of shelf to be alleviated as far as possible, reduce steel consumption, reduce shelf requirement of bearing capacity to ground, warehouse, meet storage needs.Not only the design of shelf needs genuine goods at a fair price, and the surface treatment of shelf is also extremely important.

Summary of the invention

The invention provides a kind of method of shelf surface process.The method of shelf surface process of the present invention, is realized by following technical proposals:

(1) remove the greasy dirt of surface of the work, dust and rusty stain, and it is anticorrosive and can increase " phosphate coating " of spray-on coating adhesive force to generate one deck at surface of the work;

(2) sprayed to equably on the surface of workpiece by powdery paints, the position easily producing electrostatic screen adopts high performance static plastic spraying machine to complete spraying;

(3) workpiece sprayed is pushed curing oven, be heated to 185 degree, and be incubated 15 minutes, blow-on is taken out cooling and is namely obtained finished product.

The method of shelf surface process of the present invention, object is exactly clearly that extend the service life of warehouse shelf, especially heavy weight shelving, wearing and tearing are at ordinary times larger in order to protect shelf.The easy oxidation by air of steel; one deck oxide can be adhered on surface; be unfavorable for the processing process in storing goods shelf later stage; the plastic-blasting on surface is difficult to and column close adhesion; for the effect of the service property (quality) and plastic-blasting of guaranteeing the shelf later stage; need first by the oxide removal of shelf surface, the object of Here it is acid washing phosphorization.

Detailed description of the invention

Below by specific embodiment, the present invention is further illustrated.

1, shelf pre-treatment

A, object: remove the greasy dirt of surface of the work, dust, rusty stain, and it is anticorrosive and can increase " phosphate coating " of spray-on coating adhesive force to generate one deck at surface of the work.

B, main technological steps: oil removing, rust cleaning, neutralization, cleaning, table tune, phosphatization, passivation.Workpiece after pre-treatment not only surface there is no oil, rust, dirt, and the original glossiness surface of silvery white generates the even and coarse grey phosphating coat being not easy to get rusty of one deck, can the antirust adhesive force that can increase again plastic-blasting layer.Common pre-treatment has immersion type and fountain two kinds, and immersion type needs multiple soaking compartment; Spray then needs on spraying line, arrange one section of spray line.

C, pre-treatment master operation: pickling, phosphatization

The object of pickling is rust cleaning, also can oil removing. but the easy corrosion of workpiece after pickling, so usually carry out phosphorating treatment.

The object of phosphatization is rust prevention during manufacture, forms one deck phosphating coat at surface of the work, makes metal surface have lubricity, and increase the plasticity of material, for painting technology, it is good bottom, can improve adhesive force and corrosion resistance, ensures that workpiece is stainless for a long time.

Also have a kind of processing mode---blasting treatment, effect is better than acid washing phosphorization, but cost is higher than acid washing phosphorization, and unfriendly to environment.Sandblasting (ball) eliminates rust, mainly do in order to reach surface cleaning and suitable roughness with particle jetting erosion, equipment comprises open type shot-peening (sand) rust remover, closed shot-peening (sand) machine, vacuum shot-peening (sand) machine, the application of open type shot-peening (sand) machine is comparatively extensive, the all impurity in metal surface can be removed comparatively up hill and dale, as oxide skin, corrosion and old paint film, the high 4 ~ 5m2/h of rust cleaning efficiency, machinery degree is high, and derusting is good.Because abrasive material generally can not reclaim, have impact to other operations, site clearing bothers, and environmental pollution is heavier, is recently limited gradually to use.

2, electrostatic spraying

Object: sprayed to equably on the surface of workpiece by powdery paints, special workpiece (comprising the position easily producing electrostatic screen) should adopt high performance static plastic spraying machine to complete spraying.

Processing step:

Utilize electrostatic absorption principle, workpiece surface uniform spray one deck powdery paints;

The powder fallen is reclaimed by recovery system, can use after sieving again

3, hot setting

Object: the powdery paints of surface of the work be heated to the temperature of regulation and be incubated the corresponding time, making it fusing, levelling, solidification, thus the surface of the work effect obtaining that we want.

Processing step: the workpiece sprayed is pushed curing oven, is heated to predetermined temperature (general 185 degree), and is incubated the corresponding time (15 minutes); Blow-on is taken out cooling and is namely obtained finished product.

Prompting: a, curing oven are made up of " heating system " and " thermal-insulating body " two parts, and wherein " heating system " comprises control system; B, solidification link can adopt box curing oven (one end can be selected to open the door or two ends enabling); Also through type drying tunnel (in spraying line, workpiece by constant temperature drying tunnel, completes solidification with certain speed) can be adopted.

4, decoration process

Object: make the workpiece after electrostatic spraying reach a certain special appearance as: various wood grain, decorative pattern, to add lustre to.

Claims (1)

1. a method for shelf surface process, is characterized in that comprising the following steps:

(1) remove the greasy dirt of surface of the work, dust and rusty stain, and it is anticorrosive and can increase " phosphate coating " of spray-on coating adhesive force to generate one deck at surface of the work;

(2) sprayed to equably on the surface of workpiece by powdery paints, the position easily producing electrostatic screen adopts high performance static plastic spraying machine to complete spraying;
