Abstract
The invention belongs to process for treating surface, and in particular to a kind of minimizing technology of the inorganic sealant after metal surface worst hot case.Technical scheme is as follows: a kind of minimizing technology of the inorganic sealant after metal surface worst hot case, carries out blast using plastics sand, is removed to the inorganic sealant after the worst hot case of metal surface, to realize that metal surface is cleaned.The minimizing technology of inorganic sealant after metal surface worst hot case provided by the invention, the inorganic sealant after quickly and effectively capable of thoroughly removing metal surface worst hot case, the metal base surface state after removal is unchanged, can satisfy fluoroscopy requirement.
Description
Technical field
The invention belongs to process for treating surface, and in particular to a kind of inorganic sealant after metal surface worst hot case is gone
Except method.
Background technique
In aviation field, difference has been respectively coated according to duty requirements in the mating surface of spare part or outer surface in part
The high temperature resistant inorganic sealant of the trade mark, heat resistant coating etc., to guarantee the leakproofness of each system and the heat resistance of part etc. in work
It is required that part original coating surface or neighbouring surface need to be removed because of trickling adherency when the duty cycle terminating to carry out decomposing repairing
Coating, to meet subsequent fluoroscopy demand.The type coating because of working repeatedly through up to 700 DEG C and following high temperature, make its with
Matrix adhesiveness is extremely strong, is difficult to be removed with general remover after decomposition, and domestic existing coating removal agent is chiefly used in one at present
A little low temperature coatings, are not suitable for the coating after hot operation, though and some finished product removers have certain removal effect, but still it is difficult
To completely remove, and concrete composition is unknown, there is stronger corrosivity, cleaning is difficult to ensure after use thoroughly, there are serious corruption
Erosion risk, especially component parts do not allow to impregnate using chemical solution.
In actual production, more smooth for part base solid surface and a small amount of adherency or the not strong seal coating of adhesiveness,
Scraper mechanical removal, but easy damaged matrix are generally used, and removal is not thorough, and influences fluoroscopy effect；Another method is
Using emergy method is blown, this method is removed more thoroughly, but can change Substrate State and size, and due to obturaging ring inner surface
Dotted sealant size uneven thickness, extremely strong with matrix adhesion after hot operation, such as complete blast removes, and will cause and does not glue
The surface size of attached sealant is reduced seriously, is affected to part, and for the subsequent part for having fluoroscopy requirement, because blowing
Matrix reset condition can be covered or be interfered to emergy, be not permitted in fluoroscopy pre-treatment.
Summary of the invention
The present invention provides a kind of minimizing technology of the inorganic sealant after metal surface worst hot case, can be quickly and effectively thorough
Inorganic sealant after the removal metal surface worst hot case at bottom, the metal base surface state after removal is unchanged, Neng Gouman
Sufficient fluoroscopy requirement.
Technical scheme is as follows:
A kind of minimizing technology of inorganic sealant after metal surface worst hot case carries out blast using plastics sand, to gold
Inorganic sealant after metal surface worst hot case is removed, to realize that metal surface is cleaned.
The minimizing technology of inorganic sealant after the metal surface worst hot case, preferred embodiment are the plastics
Sand be urine formaldehyde resin sand, hardness be hardness Barcol 3.5-4.0, granularity be 40-60 mesh, blast pressure be wind pressure 0.2MPa~
0.25MPa, blast angle are 45 ± 5 °, and blast distance is 50-100mm.
The invention has the benefit that the present invention quickly and effectively can thoroughly remove the nothing after the worst hot case of metal surface
Machine sealant, the metal base surface state after removal is unchanged, can satisfy fluoroscopy requirement.
Detailed description of the invention

Fig. 2 is that GH4169 part blows resin sand rear surface pattern in embodiment 1；
Fig. 3 is that GH738 part blows resin sand front surface pattern in embodiment 2；
Fig. 4 is that GH738 part blows resin sand rear surface pattern in embodiment 2.
Specific embodiment
A kind of minimizing technology of inorganic sealant after metal surface worst hot case carries out blast using plastics sand, to gold
Inorganic sealant after metal surface worst hot case is removed, to realize that metal surface is cleaned.The plastics sand is X-OFF board
II type of Type urinates formaldehyde resin sand, meets MIL-P-85891A requirement, and hardness is hardness Barcol 3.5-4.0, granularity 40-60
Mesh, blast pressure are wind pressure 0.2MPa~0.25MPa, and blast angle is 45 ± 5 °, and blast distance is 50-100mm.
Embodiment 1:
Use basis material for the part of GH4169, to its inner surface adherency through 700 DEG C of hot operations cross without secret
Sealing is removed, sand fineness 40-60 mesh, wind pressure 0.2MPa, and 45 ° of blast angle, blast distance 70mm.As shown in Fig. 2, zero
The sealant on part surface all removes, and only once the mark of adhesive sealing gel exists, and the Substrate State of nonadherent sealant is basic
Unchanged, former Vehicle Processing tool marks are still high-visible.
Embodiment 2:
Use basis material for the part of GH738, the inorganic sealing crossed through 700 DEG C of hot operations to the adherency of its inner surface
Glue is removed, sand fineness 40-60 mesh, wind pressure 0.25MPa, and about 45 ° of blast angle, blast distance 90mm.As shown in figure 4,
The sealant of piece surface all removes, and only once the mark of adhesive sealing gel exists, the Substrate State base of nonadherent sealant
This is unchanged, and former Vehicle Processing tool marks are still high-visible.
