The post-processing and polishing methods for the production process of hand board models can generally be divided into three types: wet polishing, mechanical polishing, and dry polishing. (1) Mechanical polishing: In order to improve work efficiency during large-scale construction, mechanical polishing methods can be used, such as electric polishing machine disc type and vibration type. (2) Dry polishing: Use sandpaper for polishing. Suitable for polishing hard and brittle paint, its disadvantage is that a lot of dust will be generated during operation, which affects environmental hygiene. (3) Wet polishing: Use sandpaper dipped in water or soapy water to polish. Water grinding can reduce grinding marks, improve the smoothness of coatings, and save sandpaper and labor. However, attention should be paid to spraying the lower layer of paint after water grinding. Firstly, it is necessary to wait for the water grinding layer to completely dry before applying the lower layer of paint, otherwise the paint layer can easily turn white. Additionally, substrates with strong water absorption are not suitable for water grinding.
There is also a special polishing method: the coating requirements should be noted as "light grinding", such as for sealing paint, after local repairs, etc. At this time, finer sandpaper and skilled hands should be used. On the contrary, it will be counterproductive.
When polishing, attention should be paid to the issue, first of all, coarse sandpaper needs to be used for rough machining and polishing. Remove the thick burrs on the surface before polishing with fine lines. Sandpaper can be divided into different grades such as 8001000. Then perform different degrees of polishing according to the surface requirements of the product! After one polishing, the roughness of the product surface can be amplified by spraying a layer of atomic ash. To the extent that defects can be seen with the naked eye. Afterwards, localized modifications can be made with focus until a product has completed the entire polishing process.
