The continuous development of industry will drive the development of some other industries. Our handcraft is one of them. The development in the industry is still relatively OK. So what are the relevant conditions for handling handcraft? Let's make up a small group of Jinan handicraft factory to talk about it for us!
After the completion of the hand board, if painting treatment is needed, it should be noted that SLA laser formed workpieces are not suitable for high gloss surface treatment, because the material used in SLA is a kind of photosensitive resin, and the adhesion of the hand board factory to the paint is not very good. The gloss is not very good.
Parts processed by CNC, including PP and POM materials, are not suitable for surface painting treatment, and the materials do not have adhesion with paint. Before painting, the hand board factory should carry out sandpaper grinding. There are several types of sandpaper, including coarse sandpaper and fine sandpaper. The workpiece can be polished while stained with water. Grind with fine sandpaper. Then you can sandblast and spray the bottom ash. If the surface is high gloss, it needs to be polished more finely, and then spray a layer of primer for grinding.
According to the specific production site conditions and different surface conditions of the workpiece, the main purpose of the physical means is to eliminate the control factors affecting the treatment quality and cycle in chemical treatment, and maintain the service life of chemical agents. For example, for the treated new products, excessive oil, dust, iron filings, block rust, floating rust, excessive oxide scale and products that cannot be pickled are manually scrubbed and removed (mainly using wire brush and abrasive cloth), and then the rust dust is removed by compressed air after treatment.
The handcraft factory can reduce the loss of oil and rust removal fluid, avoid the loss caused by over treatment of workpieces, shorten the chemical treatment cycle, and improve the service life of the treatment fluid. The pretreatment degreasing should be scrubbed with fully diluted degreasing agent. It is strictly prohibited to use organic solvents (such as gasoline and banana water) to avoid polluting the deoiling tank liquid and forming organic solvent solid protective film on the timely surface Quality.
The above is the Jinan hand board factory's small make-up to explain to you when processing the hand board what the relevant conditions are, hoping to help you. If you want to know more, please contact our website.
