Description
Technical field
The present invention relates to epoxy resin coating removal field, the more particularly to a kind of removal of neo-epoxy resin paint material and work
Skill.
Background technology
Fancase epoxy resin coating is mainly used in the adhesion primer before part is bonded or as protection piece surface
Anti-corrosive paint, adhesion is very good, impact resistance ability flawless and chip off-falling under the impulsive force of 4.52N/M；It is environment resistant in liquid
Do not occur situations such as blistering, fouling and loosening after being soaked 7 days in force feed；Salt fog corrosion resistance is more than 1000 hours；Moisture resistance
Without film layer defect and loosening after testing 30 days；Heat-resistance test is after 170 hours without without film layer defect and loosening.At present with any
Except paint material can not all be removed it.
The content of the invention
The purpose of the present invention is in the case of enamelled coating is removed at present without any means and technology, to find a kind of new going
Paint removal layer material and tackling key problem work out suitable process, be applied to the removal of CF34-10 aft-fan casing part enamelled coatings.Afterwards
Up to more than 1 meter 5, appearance is complicated, there is many places groove and boss, and matrix material is aluminium alloy for fancase maximum outside diameter, with blowing
The mode paint removal of sand has and easily causes part deformation, therefore a kind of new except paint material extremely redemption of the application to part has
Important meaning.
The invention provides a kind of neo-epoxy resin paint removal material and technique, it is characterised in that：Heavy epoxy resin
Solidified paint remover, can effectively remove the epoxy resin and polyurethane paint after solidification；
This enamelled coating remover is a kind of diphasic liquids, is constituted by 2 layers, above oil sealing layer be the volatilization for preventing paint removal solution,
Flash-point is 190 DEG C, is a kind of mineral oil, does not contain phenolic compound and heavy metal；Cutting optimal is paint removal solution, and concentration is about
1.07 grams per milliliters, paint removal solution composition constitutes as follows, mass percent：
Technological parameter：80 DEG C -110 DEG C will be heated to except white spirit, part will be completely submerged in lower floor's paint removal solution, used
Solution is stirred recirculation unit always so that lower floor's solution is constantly in flow regime, shape according to part, big
Small different with thickness of paint layer, the paint removal time is 1.5-4 hours；Treat that enamelled coating all loosens, part is proposed from solution with crane,
When by upper strata oil sealing layer, oil sealing layer also functions to the effect that enamelled coating is washed out that will do not come off entirely.
Alcohol is dipped in before paint removal with clean non-felt to scrub part, then by parts fixation on fixture；Will paint
During layer remover is poured into except paint bath, the thickness of oil sealing layer is checked after being sufficiently stirred for, first measure tank liquor depth using glass bar, then
The depth of oil sealing layer is measured using a thin glass bar, glass tube is taken out, blocks that glass tube is suitable for reading with thumb, measurement oil sealing layer is extremely
It is few 200 millimeters, if deficiency is being remeasured to closing oil is added in tank liquor；
Part oil removing：
Part is totally immersed into 45-60g/l degreasers TURCO 4215, solution temperature requirement is in 45 DEG C -55 DEG C, oil removing
Time is 5-10 minutes；Then part is totally immersed into cold water washing trough, will be remained on part except oil solvent is cleaned up；Water
After washing, part dries 10-30 seconds in atmosphere, checks moisture film, and moisture film answers complete cap piece surface；With compressed air by part
Drying；Part is disassembled from fixture；
Paint removal：
90 DEG C -100 DEG C will be heated to except white spirit, it is molten that the part that will be loaded on fixture is completely submerged in lower floor's paint removal
Liquid, is stirred always using recirculation unit to solution, lower floor's solution is constantly in flow regime, is noted except in paint bath
There can not be water；When enamelled coating softens or peels off completely, part is proposed from solution with crane, when by upper strata oil sealing layer,
Oil sealing layer also functions to the effect that enamelled coating is washed out that will do not come off entirely；
Paint removal is post-processed：
Part is drained at least 1 minute；
Residue on piece surface is removed using hydraulic giant clean；
Part is dried up using the compressed air of clean oil-free；
Part is disassembled from fixture；
Inspection：The enamelled coating of piece surface is removed completely, is had no and any is touched scuffing.
Advantages of the present invention：
Described new epoxy resin coating removal material, successfully removes enamelled coating, and can retain under part enamelled coating
The chemical oxide layer in face, protects part well.Neo-epoxy resin paint removes material and technique successfully solves rear wind
The problem of product rejection caused by enamelled coating is without method removal of fan casing, while the protection to part base solid material is also preceding institute
Do not have.
