Method and apparatus with redundancies for treating substrate plastic parts to accept paint without using adhesion promoters

Abstract

A method and device of treating an irregularly shaped article to prepare the article for painting is provided. The device includes a burner which can produce an adjustable flame tongue which can fit into crevices, openings and other irregular topographical features of an item to be painted or otherwise coated. The burner device further provides means to apply a grafting chemical on a freshly oxidized surface. Further, the invention provides means to colorize treated objects so that they may be recognized as having been treated. In another embodiment, the grafting chemicals may be enhanced with electrolytic solutions such that electrostatic methods of painting may be subsequently employed on the item. In an alternate embodiment, the burner is adapted to spray a powder inside of a generally enclosed flame, and is used in conjunction with chop guns to manufacture glass or carbon fiber preforms. In a preferred embodiment all of the main systems of the present invention are provided with redundancies that allow the continuous operation of the device. Further, the device provides means to run and modify the process either locally or by remote communication means.

Description

[0001] This application is a continuation-in-part of now-pending US Patent Application No. 09 / 836,659, filed April 17, 2001. technical field [0002] The present invention relates to a method and an apparatus for treating plastic substrate parts receiving paint, and in particular to a method and apparatus for treating plastic substrate parts receiving paint without the use of adhesion promoters, such as to properly treat flat areas, corrugations and grooves Plastic base parts. Background technique [0003] The preparation of surfaces to be painted and to receive paint is a common practice in the paint industry and paint discipline. Properly prepared surfaces are more likely to produce desired results and maintain proper paint condition over time. Preparation techniques vary according to the material being painted, the type of primer, the pigments and / or paints used, the manner in which the paint is applied, and the conditions to which the painted article is subjected, among...

Problems solved by technology

[0012] Another problem with existing methods of processing plastic parts is that once the part has been processed, it is often difficult to distinguish between treated and untreated parts without complex testing

In many cases, treated items are mixed up with untreated items, resulting in wasted material and time during reprocessing, and often the reprocessed part surface is too weakened

[0013] Another problem is that in typical systems used in any field where supplies of chemicals must be mixed and fed, there is a tendency during the duty cycle to stop the machinery and / or require routine maintenance so that it can continue normally Work
