Abstract
The invention discloses a disposing technology of stainless steel container surface, which comprises the following steps: adopting mechanic polishing to predispose, polishing local mirror, disposing decorative prevention, disposing shot-blast with diameter at 0.2-1.2mm, cleaning surface, coating surface, adsorbing dust, blowing dust, brushing, spraying film liquid, coating film liquid through high-pressure static specific equipment.
Description
Technical field
A kind of technology that is applied to handle the rustless steel container surface belongs to rustless steel container and makes the field.
Background technology
In water work, pharmaceutical machine, food machinery, chemical machinery, often to use the container of stainless steel, this type of container must be through welding sequence in manufacturing process, weld seam oxidation easy to change, mainly take the method for acid wash passivation to handle, the outside face processing technological flow of this type of container mainly contains two kinds at present, and first kind is directly to carry out acid wash passivation to handle on former mother metal surface and weld seam, with the clear water flushing, dry back packing is finished product then.This technological process has simple and convenient, does not damage mother metal, the impregnable benefit of intensity, but just can not meet the demands for surface aesthetic and the demanding occasion of corrosion stability.Second kind is the method that adopts electro-polishing, can improve some surface qualitys and corrosion resistance, but processing bothers, the cost height, and the very high requirements for quality of out of reach, does not allow to realize with the method for big workpiece.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of and can overcomes the above problems, and both can improve the surface aesthetic and the corrosion resistance of rustless steel container greatly, again the process for treating surface scheme of implementing easily.
The present invention adopts mechanical polishing pretreatment, local mirror-like finish to handle, decorate protective treatment, Shot Blasting, cleaning surfaces pretreatment, finish coat protective treatment, surface evenness, aesthetic measure, antiseptic property all are significantly increased, avoid using chemistry or electrochemical treatment simultaneously, make the comparatively clean environmental protection of processing and easy, thereby realized the purpose of invention.
Be generally plate in the hot rolling for container with stainless steel sheet, surface quality is relatively poor, and steel plate weight is big, very easily damage in loading and unloading and the transportation, the pretreated purpose of mechanical polishing of the present invention is to remove colliding with of raw sheet surface, scratching also makes the surface of hot rolling become smooth simultaneously, for subsequent treatment lays the first stone, in order to increase the stereovision of outward appearance, mirror-like finish is carried out in the part of container to be handled, protect at the minute surface place with the protection negative, carry out directed Shot Blasting then, unload the protection negative and just formed required decorative pattern, cleaning pretreatment is carried out on the surface, and spary cuticula protection has then just formed appearance looks elegant, the quality scale height, the resistant to corrosion product surface.
The technology of the present invention effect:
The present invention has improved the surface accuracy of container greatly, has improved the class of product, the processing of big part is become be more prone to, and has stopped chemical pollution, has reduced working strength of workers.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
Container adopts plate in the austenitic stainless steel hot rolling, thickness 4mm～16mm, the container diameter of making is 600mm～2600mm, the length of container is 1000mm～6000mm, the container welding finishes to carry out the single-piece mechanical polishing, because of container bigger, rubbing down generally should adopt the abrasive band automatic Polishing, under the situation about not satisfying the requirements, also can adopt artificial hand polishing, but it is second-rate, efficient is lower, whole rubbing down finishes, according to the position that will decorate, decorative position is carried out mirror-like finish to be handled, successively adopt 120 orders, 360 orders, 800 orders, 1500 purpose abrasive bands and polishing buff are handled respectively, must select suitable buffing paste when polishing at last, until the minute surface of dishing out, under different situations, can suitably adjust the order number of emery cloth, but must follow first coarse sand, the principle of back fine sand, polishing finishes, dress protection negative, the protection negative must closely be adjacent to protection coating, preferably adopt the unit clamp clamping, guarantee that protection is reliable, protection negative clamping is finished, carry out directed ball blast, employing is led the ball device and is led ball, avoid the diffusion of bullet fitfull, bullet must adopt the austenitic stainless steel material, and preferably identical with quality of parent material, the diameter of bullet is controlled between 0.2mm～1.2mm, ball blast finishes, carry out the cleaning surfaces pretreatment, method is to adopt dust suction or drifting dust dedusting, preferentially uses dust suction, further softening water flushing again after the dedusting, after the dustfree environment drying, adopt the protection of specialized equipment spray cuticula liquid, this specialized equipment can produce high-pressure electrostatic, container is connected on positive pole, spray gun connects negative pole, and cuticula liquid particulate is electronegative like this, the stainless steel surfaces positively charged, improve the antiseptic property on surface after the absorption greatly, cause the coating attenuation for some dead angles for avoiding electrostatic interference, the method for taking to shield isolating and protecting is overcome, and has guaranteed the single-piece protection effect.
Claims (4)
1, a kind of surface treating technique for stainless steel container is characterized in that adopting mechanical polishing pretreatment, local mirror-like finish to handle, decorate protective treatment, Shot Blasting, cleaning surfaces pretreatment, finish coat protective treatment.
2, a kind of surface treating technique for stainless steel container according to claim 1 is characterized in that Shot Blasting adopts directed ball blast, and the diameter of used bullet is between 0.2mm～1.2mm.
3, a kind of surface treating technique for stainless steel container according to claim 1 is characterized in that the cleaning surfaces pretreatment, and method is to adopt dust suction or drifting dust dedusting, further softening water flushing again after the dedusting.
4, a kind of surface treating technique for stainless steel container according to claim 1, it is characterized in that the protection of finish coat protective treatment employing specialized equipment spray cuticula liquid, this specialized equipment can produce high-pressure electrostatic, container is connected on positive pole, spray gun connects negative pole, and the method for taking to shield isolating and protecting realizes the spraying at dead angle.
