The method includes the specific steps that first, putty is thickened layer by layer, the putty is fully dried, the bubbling phenomenon is eliminated, then fine sandpaper is used for conducting fine grinding, the concave and convex point problem and the scraper trail problem of a workpiece can be solved, and accordingly the surface smoothness can be guaranteed; second, four-level filtering is used, a micro heat absorption drying machine is used for filtering air at the last level, air blowing is performed for more than 30 min before spraying first, and air and steam in a pipeline are removed; third, watering and mopping are conducted first two hours before plastic spraying, and plastic spraying is carried out when it is guaranteed that no dust exists in the field environment; (4) the longitudinally and transversely alternate spraying technology is adopted, transverse spraying and longitudinal spraying cross operation can be conducted, the spray gun walking evenness to a sprayed piece can be guaranteed, the bottom of the workpiece is not exposed, powder falling is avoided, and plastic powder can be evenly attached; fifth, a pure wool polishing wheel is matched with wax for conducting grinding and polishing, and therefore the high brightness standard and effect can be achieved.
Description
Technical field
The present invention relates to safety box field, particularly relate to a kind of safety box surface treatment method.
Background technology
A lot of safety box enterprises making something perfect even more perfect in appearance all at product at present, traditional technique is surface plastic spraying process, but workmanship of spraying plastics exists many drawbacks.In plastic-blasting pretreatment stage, because atomized ash is larger with steel plate expansion coefficient difference, when variations in temperature is large, easily occur causing atomized ash to ftracture because of rising-heat contracting-cold, and atomized ash surface smoothness after blade coating is bad; Uneven owing to spraying at spraying stage, easily occur that show-through, dry linting, molding powder adhere to uneven phenomenon, easily there is water spot and surface impurity in the surface of the work after conventional workmanship of spraying plastics, surface finish is also undesirable, causes end product quality level uneven.
Occur afterwards atomized ash and workpiece utilize baking vanish to replace workmanship of spraying plastics to be made by product casing beautiful attractive in appearance.But the fatal drawback of baking vanish is the seriously polluted of paint, deals with expense very high again; Newly-built oil paint production line also will go up corresponding blowdown waste air and labour protection corollary apparatus, be also difficult to after building up in addition by the environmental protection of government, fire department ring upon ring; Therefore be that acts and efforts for expediency are inadvisable with long-term sight baking vanish.
Summary of the invention
For the present situation of above-mentioned prior art, technical problem to be solved by this invention be to provide a kind of eliminate atomized ash cracking phenomena, the attachment of surface of the work molding powder evenly, surface of the work is without water spot dust and the good and safety box surface treatment method of energy-conserving and environment-protective of fineness.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of safety box surface treatment method, comprises the following steps:
(1) pre-treatment
A, oil removing, rust cleaning, phosphatization, passivation: deoil to surface of the work, become rusty, dirt process, make it on the glossiness surface of original silvery white, generate the even and coarse grey phosphating coat of one deck;
B, Puttying: after surface of the work process, use atomized ash to carry out Puttying to surface of the work, adopt and successively thicken, and carry out abundant drying after blade coating terminates;
C, polishing: use sand paper to carry out fine grinding to surface of the work.
(2) plastic-blasting pretreatment
A, pipeline are except aqueous vapor: arrange level Four and filter, and in the end one-level uses low-grade fever adsorptive drier to filter air, advanced line space spray before spray, and the time is 30min;
B, on-the-spot dedusting: spraying starts front 2h, carries out watering mop floor to scene.
(3) electrostatic spraying
Novel molding powder powdery paints is sprayed on surface of the work equably, adopts spraying coating process alternate in length and breadth, carry out horizontal spray, perpendicular spray cross-operation.
(4) hot setting
The workpiece sprayed is pushed curing oven, and work is heated to 185 °-200 °, continues 15min-20min.
(5) polishing, waxing
Use polishing wheel to coordinate wax fat, sanding and polishing process is carried out to the workpiece after solidification.
Further, b, Puttying in described step (1), atomized ash thickness is not more than 1mm.
Further, c, polishing in described step (1), selected sand paper order number is greater than 250 orders.
Further, the material that in described step (5), polishing wheel adopts is pure wool.
Compared with prior art, the invention has the advantages that: the present invention adopts 1) atom successively thickeies, and allows its sufficient drying successfully solve foaming, then carry out fine grinding with fine sandpaper and solve workpiece and have sags and crests and scraper mark, guarantee smooth surface; 2) adopt 4 grades of filtration, in the end one-level low-grade fever adsorptive drier carries out overanxious to air, and before spray, first allows air sky blow be no less than 30min, makes the air previously in pipeline and aqueous vapor discharge; 3) before adopting plastic-blasting, 2h first sprinkles water and mops floor, and ensures that site environment does not have to carry out plastic-blasting again during dust; 4) adopt spraying coating process alternate in length and breadth, carry out horizontal spray, perpendicular spray cross-operation, guarantee that spray gun walks rifle to spray piece even, workpiece is not show-through, and dry linting, molding powder attachment are not evenly; 5) adopt polishing wheel of pure wool to coordinate wax to carry out sanding and polishing, thus reach standard and the effect of high brightness.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based in the present invention being embodiment, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of safety box surface treatment method, comprise the following steps: (1) pre-treatment: surface of the work is deoiled, becomes rusty, dirt process, make it on the glossiness surface of original silvery white, generate the even and coarse grey phosphating coat of one deck, after surface of the work process, use atomized ash to carry out Puttying to surface of the work, adopt and successively thicken, and abundant drying is carried out after blade coating terminates, use sand paper to carry out fine grinding to surface of the work; (2) plastic-blasting pretreatment: level Four is set and filters, and in the end one-level uses low-grade fever adsorptive drier to filter air, advanced line space spray before spray, the time is 30min, and spraying starts front 2h, carries out watering mop floor to scene; (3) electrostatic spraying: sprayed to equably on surface of the work by novel molding powder powdery paints, adopts spraying coating process alternate in length and breadth, carries out horizontal spray, perpendicular spray cross-operation; (4) hot setting: the workpiece sprayed is pushed curing oven, work is heated to 185 °-200 °, continues 15min-20min; (5) polishing, waxing: use polishing wheel to coordinate wax fat, sanding and polishing process is carried out to the workpiece after solidification.
