Se precisar de algum processo de tratamento de pintura em spray após terminar os protótipos, observe que a peça de trabalho de prototipagem rápida SLA não se adapta ao tratamento de superfície de alto brilho, porque utilizou a resina fotossensível, o que não é bom para aderir tinta a óleo para obter o efeito de brilho desejado. O CNC Prototype Machining work-pieces, incluindo feito de PP e POM, não é adequado para lidar com a superfície para pintura em spray, porque os materiais não possuem adesividade com pintura em spray. Antes de pintar, it needs to polish with abrasive paper. The abrasive paper is divided into several types, such as raw abrasive paper and fine abrasive paper. It can polish the touching water edge of the work-piece edge, and polish it with the finest abrasive paper for the last time, then it’s time to spray grit and bottom ash. If its surface has been treated with high glossy, it needs to be polished finer, and then spray a layer of priming paint to polish it again.
The physical means, adopted in accordance with the specific conditions of production site and different surface appearances of work-piece with prototype treating, mainly aims at eliminating the control factors that influence the processing quality and cycle in the chemical treatment, as well as aims at maintaining the working life of chemical agents. Por exemplo: Artificially scrub and remove (mainly adopt wire brush and abrasive cloth) the excessive oil stain, dust, iron filings, piece of rust, floating rust, as well as too thick oxide skin, and products that cannot be acid washed, on the surface of new handled product. Then remove the rust dust with compressed air. It also helps reduce lots of loss of degreasing and rust removing solution, avoid the loss of over-treating work-piece, shorten the chemical treatment cycle, and improve the working life of treating fluid. The pre-treating degreasing should apply the fully diluted degreaser to scrub, and should be strictly prohibited to apply organic solvent (such as gasoline and lacquer thinner), so as to avoid polluting the degreasing bath solution and forming organic solvent solid protective films on its timeliness surface, which will lead to influence the degreasing quality.
