Abstract
A method for constructing an epoxy resin coating on a steel wire mesh on a metallic surface is disclosed. The method includes the steps of fixing the steel wire mesh on the metallic surface of a base body in a welding manner by a melting method like spot welding, and coating the epoxy resin on the steel wire mesh by an epoxy resin coating method to obtain the epoxy resin coating. Since the bonding strength of the epoxy resin is combined with the welding strength between the steel wire mesh and the metallic surface of the base body, the epoxy resin coating on the steel wire mesh on the metallic surface has the advantages of no shedding, no uncoating, strong and controllable bonding strength and the like, and can be widely utilized to epoxy resin cavitation prevention coatings in a hydroelectric plant and anti-corrosion coatings in chemical industry.
Description
Technical field
The invention belongs to protective finish construction category, be applicable in metal base surface construction tool sticking epoxy coating construction method technical field.
Background technology
At present, the construction method that metal surface is coated with epoxy resin has: a cloth three is coated with, two cloth four are coated with, three cloth five are coated with, four cloth six are coated with, five cloth seven are coated with ring, layering and repeatedly brush the methods such as epoxy resins anticorrosive coat, no matter adopt that method, its operation is substantially identical, and just the number of plies of cloth is different with the pass being coated with epoxy resin.The basic construction method of epoxy coating is as follows: process metal surface by the mode such as mechanical grinding, solvent clean, the rusty stain of metal surface, grease or other attachment is removed clean; Brushing bed material, selects epoxy resin brushing excessive, and after curable epoxide is complete, Puttying bottoming forms bed material transition zone; Require to select different anti-corrosion resins and fiber to make anticorrosive coat, enhancement Layer, appearance anticorrosive coat according to service condition or coating performance; The process of appearance anticorrosive coat, after coating makes, appearance will carry out grinding process, reaches impulse-free robustness, smooth, clean.
No matter take the epoxy coating that above-mentioned that method is formed on the metal surface, all exist with parent metal bond strength not high, the shortcomings such as bond strength is uncontrollable.Wash away at vibration, media impingement, medium, under the factor acting in conjunction such as thermal (temperature difference) stress, water hammer, easily cause epoxy coating to come off.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned epoxy resin construction technology, by changing construction method, improving the bond strength of epoxy coating and metallic matrix, preventing epoxy coating from coming off.
Utilize melting mode, the metal object of steel wire or band ailhead and base metal surface intermittent are welded to connect, epoxy resin multipass is coated in the steel wire epoxy coating being furnished with and the metal surface of steel wire or band ailhead is formed, because the weld strength of the caking property of epoxy resin itself and the metal object of steel wire or band ailhead superposes, obtain higher bond strength.Indirectly bond strength can be controlled by controlling pad quantity.
The present invention is realized by following technical proposal.
A kind of metal surface steel wire epoxy coating construction method, feature of the present invention is, solidifies the steel wire having and weld together with parent metal in epoxy coating, and the method step is:
1) base metal surface carries out pretreatment, and employing mechanical grinding, solvent clean mode remove grease, dirt, rust, oxide skin, the old coating of base metal surface; Carry out twice sandblasting with 80# quartz sand and 16# Brown Alundum coarse sand, make metal surface form hair side unevenness, increase bond area;
2) use roll extrusion mode, make steel wire be close to base metal surface;
3) by melting mode, the metal object of steel wire or band ailhead and base metal surface intermittent are welded to connect;
4) steel wire to the distance of metal surface is adjusted to 0.5 to 1.5 millimeter.;
5) epoxy resin prepared is spread upon in the metal object base metal surface being fixed with steel wire or band ailhead, form steel wire epoxy coating;
6) steel wire having and weld together with parent metal is solidified in epoxy coating.
Content of the present invention is set forth further below in conjunction with drawings and Examples.
Accompanying drawing explanation
Fig. 1 is metal surface steel wire epoxy coating sectional drawing;
Fig. 2 is that 350MW water turbine set draft tube easily cavitates the sectional view after pipeline section inner wall surface brushing steel wire epoxy resin.
Detailed description of the invention
A kind of metal surface steel wire epoxy coating construction method, feature of the present invention is, the method is:
1) base metal surface pretreatment, the mode such as mechanical grinding or solvent clean is adopted to remove the grease, dirt, rust, oxide skin, old coating etc. of base metal surface, carry out twice sandblasting with 80# quartz sand and 16# Brown Alundum coarse sand, make base metal surface clean and with unevenness;
2) use roll extrusion mode, make steel wire be close to base metal surface;
3) by melting mode, the metal object of steel wire or band ailhead is connected with base metal surface intermittent is firm;
4) steel wire and base metal surface is made to produce the gap of 0.5 to 1.5 millimeter with " one " word screwdriver;
5) epoxy resin prepared is spread upon in the metal object base metal surface being fixed with steel wire or band ailhead.
6) steel wire epoxy coating in metal surface is firmly attached in base metal surface by the cementitiousness of epoxy resin self, the solder joint between steel wire and parent metal.
See Fig. 1, this figure is metal surface steel wire epoxy coating sectional view.Parent metal 1 obtains surface that is clean and band unevenness through pretreatment; The metal object 4 of steel wire or band ailhead is close in base metal surface by roll extrusion mode; By melting mode, form spot welds 3 at steel wire or between the band metal object 4 of ailhead and parent metal 1; Steel wire and base metal surface is made to produce the gap of 0.5 to 1.5 millimeter with " one " word screwdriver; The epoxy resin 5 prepared is spread upon on the parent metal 1 of the metal object 4 being fixed with steel wire or band ailhead; The metal object 4 of epoxy resin 5, steel wire or band ailhead forms steel wire epoxy coating jointly; Steel wire epoxy coating and parent metal are by bonding and weld two kinds of modes and form faying face 2.
See accompanying drawing 2, this figure is that 350MW water turbine set draft tube easily cavitates the sectional view after pipeline section inner wall surface brushing steel wire epoxy resin.Draft tube specification is φ 6000 × 30, is highly 1500 millimeters, steel wire epoxy coating 3 millimeters.Draft tube inwall easy cavitation venturi section parent metal 1 removes the grease, dirt, rust, oxide skin, old coating etc. of base metal surface through mechanical grinding mode, carry out twice sandblasting with 80# quartz sand and 16# Brown Alundum coarse sand, make draft tube inwall obtain surface that is clean and band unevenness; Steel wire 4 roll extrusion mode is close on draft tube inwall inner surface; By butt-joint mode, be 2 by order number, string diameter is 1 millimeter, material is 304, the steel wire of width 1.5 meters, length 30 meters makes to form spot welds 3 between steel wire 4 and draft tube inwall 1 by the solder joint distribution of 30 × 30 millimeters; Steel wire and base metal surface is made to produce the gap of 0.5 to 1 millimeter with " one " word screwdriver; To add dilute Ji in right amount, the solidification of silica flour helps: resin ratio is that the bis-phenol E epoxy resin 5 of 25:100 spreads upon and is fixed with on the turbine draft tube inwall 1 of steel wire 4; Epoxy resin 5, steel wire 4 are through the steel wire epoxy coating of 4 times brushing formation 3 millimeters thick; Steel wire epoxy coating and parent metal are by bonding and weld two kinds of modes and form faying face 2.
