In recent years, surface adhesion coating technology has been widely used in the maintenance of equipment in our country, and is suitable for the repair of parts and equipment of various materials. Its working principle is to add special fillers such as molybdenum disulfide, metal powder, ceramic powder and fiber Adhesive is directly applied to the surface of materials or parts to make it wear-resistant and corrosion-resistant. It is mainly used for surface strengthening and. Its process is simple, convenient and flexible, and reliable. It does not require special equipment, and only needs to be equipped. The glue is applied to the surface of the cleaned parts, and it can be trimmed after curing.It is often operated at room temperature and will not cause the parts to have thermal equivalent influence and deformation.
Although the gear pump adhesion process is relatively simple, the actual construction requirements are quite strict. Only by selecting a good adhesive, high adhesion strength cannot be obtained. It is necessary to select a suitable adhesive and strictly follow the correct process method To apply a suitable adhesive, it is necessary to strictly follow the correct process method to obtain a satisfactory adhesion effect.
(one) coating
Apply a thin layer of repair agent on the adhesive surface first, repeatedly scrape it to fully wet the parts, and then evenly apply to the specified size, leaving a finishing allowance. Move in one direction as much as possible during the coating, The reciprocating coating will wrap air in the glue to form bubbles or pores.
(2) The pre-processing is ground into a grooved mesh with fine sandpaper to expose the nature of the matrix.
(3) After cleaning and activation treatment, use acetone or a special cleaning agent. Then use sandblasting, flame or chemical methods to improve surface activity.
(4) Finishing, cleaning or post-processing for fine boring or using assorted files, fine sandpaper, oil stone to finish the sticky surface to the required size
(5) Preparation of repairing agent When using the repairing agent, the agent (A) and the curing agent (B) should be fully mixed in strict accordance with the specified ratio, and the color should be the same, and used up within the specified time. Match.
(6) There should be no grease, water, rust, dust, etc. on the surface of the first cleaning parts. It should be rough washed with gasoline, diesel or kerosene first, and then washed with acetone.
(7) For curing, it is coated with a release agent on the steel plate and pressed on the work. Generally, it takes 24 hours to cure at room temperature, and 2-3 hours to heat curing (about 80°C).
