Description
Technical field
The present invention relates to a kind of finished metal part and use solvent-free removal rush-resisting material packaging
Process.
Background technology
Precision Machining metalwork stores and in transportation, is affected by various corrosion factors, naked
Dew metal surface is susceptible to corrosion, affects precision and the presentation quality of Precision Machining part, can give
The serviceability of whole parts brings harm and loss.Therefore, metal Seiko part storage and
Carrying out the safeguard procedures such as antirust in transportation is that the important process of corrosion loss is reduced or avoided.
Traditional antirust oil needs solvent to clear up before parts assemble, and needs consumption during cleaning
Taking outside manpower, also can cause environment pollution, the solvent removing antirust oil is all inflammable and explosive
Dangerous materials, use solvent to remove antirust oil and can bring potential safety hazard to erecting bed, for structure
When complex part uses plastic to carry out waterproofing packing, it is difficult to fit packaging, thus with type
Leaving corresponding space to aqueous vapor, rust-proof effect is difficult to reach optimum state.The most in recent years,
Domestic large-scale hydro-generating Unit moves towards many countries and regions such as South America, Africa, Europe,
Part large-scale precision processing structure complex part such as reasoning head mirror plate, the hydraulic turbine and hydrogenerator
The piece volumes such as big axle are huge, are difficult to Container Transport, and may after transporting to building-site
There is the outdoor storage of long period, have the outdoor resting period of some foreign power plants will exceed half
Year.For avoiding band large-scale metal parts that corrosion occurs in transport and storing process, use economy
The packing method being suitable for is the most necessary.Particularly need before large-scale precision part is installed at the scene
Being removed by rush-resisting material, generally, solvent clean to be used removes rush-resisting material, this meeting
Potential safety hazard and environmental pollution is brought to job site.
Summary of the invention
It is an object of the present invention to provide a kind of effective, technique convenience, economy, the polish of environmental protection
Metalwork uses the process of solvent-free removal rush-resisting material packaging, technical scheme
It is:
A kind of finished metal part uses the process of solvent-free removal rush-resisting material packaging, bag
Include following process steps:
1) dip in general organic washing agent with clean byssus and thoroughly clean there is a need to antirust
Metal surface, removes dust, water mark, oil, fat and other pollutant；
2) step 1 is dried with clean byssus again) cleaned metal surface, it is necessary to assure
The metal surface cleaning dried does not has pollutant, application to complete front metal surface to forbid with naked hands straight
Contact；
3) use coating process to be coated with by peelable for volatile rust prevention anticorrosive coating and install to step 2)
On the metal surface processed, the wet-film thickness of the peelable antirusting paint of gas phase is 50～200 micro-
Rice；
4) by step 3) after the antirusting paint dry solidification film forming of institute's application, band large-scale metal precision adds
Workpiece can store；
5) during interior storage in 12 months, before the assembling of band large-scale metal Precision Machining part, use
Manual mode is by step 4) to peel off band large-scale metal accurate for the antirust stripping lacquer of solid phase that formed
Workpiece, does not the most use any solvent.
In step 1) the middle Da Saite metallic element oils and fats cleaning using model to be PSC-002
Oil contamination is cleaned in agent, uses antirust liquid stripping lacquer application.
In step 4) in solid to the antirusting paint of application natural drying under the conditions of 15～40 DEG C
Change.
In step 4) in the antirusting paint of application started air draft under the conditions of 20～25 DEG C accelerate
Dry solidification.
Inventive principle and innovative point
Rust prevention packaging method was that large-scale precision piece surface application certain thickness routine is antirust in the past
Agent, treats that Elements in Organic Solvents thoroughly volatilizees, and is utilizing after antirust agent bulk composition dry solidification
Conventional packaging material such as plastics, anti-tarnish paper, aluminum-plastic composite membrane etc. carry out waterproofing packing.Just
Often storage expires or before transport is installed to erecting bed, needs to remove packaging, utilizes a large amount of
Organic solvent dissolves removes antirust oxidant layer.The organic solvent and the antirust agent mixture that produce can not
Reclaim, need to emit.If design of part is complicated, packaging can not conformal, rust prevention packaging
Often do not reach expection waterproofing packing effect.
The principle of the present invention is to utilize liquid antirusting paint at precision workpiece external coating, works as liquid
After gas-phase anti-corrosion paint dry solidification film forming, one can be formed at piece surface and not omit a little
Overall protective layer, for part this continuous print protective layer advantage that structure is the most complicated more
Substantially.And utilize volatile rust prevention stripping lacquer solid film itself mechanical iris action and
Middle corrosion inhibiter and the synergy of antibacterial additives, can effectively prevent air and hydrone isotonic
Enter to surface of the work, both reduced the corrosion rate of precision metal workpiece and mould degeneration, and again might be used
The anti-mechanical abrasion of raising equipment, Corrosion Protection.Because solid protecting film layer and Metal Substrate
There is the demoulding composition of trace between body, the cohesiveness of solid rush-resisting material protective layer more than with
The adhesive force of metal surface, so need not any solvent to dissolve antirust guarantor before workpiece assembles
Sheath, can become rust prevention packaging layer is peeled off from matrix surface, soon with opening by manual completely
Speed unpacking.The rust prevention packaging solid film layer peeled off can collect, and utilizes organic solvent molten
Solve recycling.The most both can ensure that antiseptic property, will not break seal again organic molten because using
Agent is discharged after cleaning and is caused environment pollution, and reduces the potential safety hazard of erecting bed.
Rust prevention packaging of the present invention construction uses the material of liquid condition to be easy to coating decoration, given
At temperature 15～40 DEG C of range of condition, natural drying solidification starts air draft under the conditions of 20～25 DEG C
Accelerate dry solidification, it is ensured that dry solidification under the state that liquid levelability is optimal, it is thus achieved that consolidate
Body protective layer thickness is uniform, when mode removes rush-resisting material packaging by hand, can make antirust
Material slabbing continuous stripping metal part surface.
The wet-film thickness of gas phase peelable antirusting paint application is 50～200 microns, dry solidification
The thickness of protecting film layer is to ensure that the equilibrium point of antirust barrier propterty and release performance.
