Abstract
The invention provides a method for removing an organic coating of a composite material. The method is characterized by comprising the following steps: placing the composite material with the organic coating on a tooling of a plastic injection machine; and adjusting parameters of the plastic injection machine, namely, keeping the pressure of a spray nozzle to be 20-40 psi (0.138-0.276Mpa), and the flow of a plastic injection medium to be 60-75 m/s, and injecting the composite material with the plastic injection medium by adopting the plastic injection machine till the organic coating of the composite material is completely removed.
Description
Technical field
The present invention relates to composite material surface process field.
Background technology
Because composite material parts cannot use paint stripper to strip organic film, the mode of polishing can only be used at present to remove releasing agent or the organic film of composite material component port surface, and efficiency is lower, and polishing dynamics is wayward.
Summary of the invention
The technical problem to be solved in the present invention:
By test, determine the relevant parameter of domestic plastics ejection medium sandblasting, reach the releasing agent of removal composite material surface rapidly and efficiently or the object of organic film, improve lacquer spraying technique production efficiency.
Technical scheme of the present invention:
A method for composite stripping organic coating, is characterized in that, comprise the following steps:
The composite being coated with organic coating is placed in the frock of moulding spray machine;
Spray machine equipment parameter is moulded in adjustment, keeps nozzle exit pressure 20 ~ 40psi(0.138-0.276Mpa), plastics ejection medium flow 60 ~ 75m/s, sprays plastics ejection medium composite with moulding spray machine, until the organic coating of composite is removed completely.
A kind of embodiment of the method for composite stripping organic coating of the present invention is that plastics ejection medium adopts thermosetting urea-formaldehyde base resin, and specification is 16-20 order, meets MIL-P-85891A standard.
Beneficial effect of the present invention:
By determining domestic plastics ejection medium sandblasting relevant parameter, the efficiency improving composite stripping releasing agent and organic film reduces operator's amount of labour, effectively improves painting quality and production efficiency.
Detailed description of the invention
Below technical solution of the present invention is described in detail:
Be placed in the frock of moulding spray machine by the composite being coated with organic coating, moulding spray machine is that the SCHLICK-BLASTROOM that Wheelabrator produces moulds spray machine;
Spray machine equipment parameter is moulded in adjustment,
(1) nozzle is apart from injected surface distance 150 ~ 250mm;
(2) nozzle and injected surperficial angle 30 ° ~ 80 °;
(3) nozzle exit pressure 20 ~ 40psi(0.138-0.276Mpa);
(4) plastics ejection medium flow 60 ~ 75m/s;
Plastics ejection medium thermosetting urea-formaldehyde base resin, specification are 16-20 order, meet MIL-P-85891A standard.
Observe injected surface attachments during injection at any time and remove state, and suitably adjust injecting time.
With moulding spray machine, plastics ejection medium is sprayed composite, until the organic coating of composite is removed completely.
Claims (2)
