Embodiment 1

[0040]A method for preparing amino molding compound abrasives for aircraft coating removal. Part of the equipment used includes blade plastic crushers, turbine pulverizers, vibrating screens, ball mills, and sandblasting machines. product. The aircraft coating is an aircraft skin surface coating, and the base material is a 2024-T3 aluminum alloy plate. Amino molding compound abrasive, its main chemical composition is C and O.

[0041] Specific steps are as follows:

[0042] 1. Broken amino molding compound

[0043] Put the amino molding compound with a Mohs hardness of 3.5~4.5 into the blade plastic crusher for crushing. The pairing ratio of the fixed blade and the moving blade of the crusher is 2:3, and the adjustment gap between the blades is 1~5mm. The blade hardness is HRC52~58, and the sieve plate aperture of the crusher is Ø8.0~Ø12.0mm.

[0044] 2. Grinding and screening of amino molding compound particles

[0045] Put the crushed amino molding compound particles in...

Embodiment 2

[0051] The difference between this embodiment and the first embodiment is that the pairing ratio of the fixed blade and the movable blade of the crusher is 4:6, and the operation is the same as that of the first embodiment.

example 1

[0053] Step 1. Amino molding compound is broken

[0054] Put the amino molding compound with a Mohs hardness of 4.0 into a blade-type plastic crusher for crushing. The crusher has 4 fixed blades and 6 moving blades. The adjustment gap between the control blades is 4mm. The hardness of the blades is HRC56. The mesh diameter is Ø8.0mm.

[0055] Step 2. Abrasive crushing and screening

[0056] Put the amino molding plastic particles crushed by the crusher into the turbine crusher for crushing. The rotor diameter of the crusher is 500mm, and the turbine speed is 3250r / min. Finally, the crushed particles are put into the vibrating screen for classification and screening. After screening The particle size grades are 60 mesh.

[0057] Step 3, preparation of abrasive

[0058] Mixing the screened particles with a particle size grade of 20-30 mesh, 30-40 mesh, 40-50 mesh and 50-60 mesh according to a certain mass percentage to obtain a polishing abrasive. The specific ratio is: the ...

Abstract

The invention discloses a preparation and application method of amino mold plastic abrasives for aircraft coating layer removal, and belongs to the technical field of material surface polishing. The preparation method of the amino mold plastic abrasives is characterized in that amino mold plastic is firstly crushed; then, crushed amino mold plastic particles are crushed and screened; the particleswith different particle size grades and obtained by screening are mixed according to a certain ratio to prepare abrasives; and the air jet machining is performed on the abrasives to remove aircraft coating layers. The aircraft coating layers are aircraft cover surface coating layers. After the air jet machining is performed on the amino mold plastic abrasives, prepared through the method, to remove the aircraft coating machines, obvious damage is not discovered on the surfaces of basal bodies, so that the removing effect of the coating layers is excellent, and the efficient, green and nondestructive removal of the aircraft coating layers can be realized. The used amino mold plastic abrasives can be recycled.

Description

technical field [0001] The present invention relates to a method for preparing abrasives for removing aircraft coatings, in particular to a method for preparing abrasives for removing aircraft coating abrasives by air-jet processing, in particular to an amino molding compound abrasive for removing aircraft coating abrasives by air-jet processing The preparation method and its use. Background technique [0002] Aircraft coatings can not only reduce the impact caused by factors such as temperature, humidity, media, abrasion and impact during the operation of the aircraft, but also prolong the service life of the aircraft and keep it in good operating condition. Therefore, aircraft coatings are very important for protection and Controlling the corrosion of aircraft structure plays a vital role in ensuring the safety of aircraft flight. However, during the operation of the aircraft, its surface coating will inevitably be affected by temperature fluctuations, high-intensity ultr...
