According to the oxidation of the outer dimensions (appropriate to relax the margin), with wood or bricks surrounded by a box, the box covered with plastic sheeting to form a concave pool, the height of the plate if the deal, there are 100MM So you can work as long as the workpiece in this pool, the next shaking, you can make the surface oxide film.

Sub-site processing. Disposal of [url=http://gobimarathon.org/yard/720-outdoor-plastic-floor-for-garden-Edinburgh.html]outdoor plastic floor for garden Edinburgh[/url] crop cesium pieces in the tank (pool) successively in different parts of the rapid change or turn in turn, and finally make the entire surface of the workpiece and the solution repeatedly contact and gradually formed and thicker oxide film operation. By using the above two methods, a large plating tank can be dispensed with, a large amount of solution can be prepared, the waste caused by long-term [url=http://gobimarathon.org/yard/719-veranda-vinyl-fence-wholesale-suppliers-in-china.html]veranda vinyl fence wholesale suppliers in china[/url] uselessness can be reduced, and the production area in the workshop can also be saved. There are three possible causes for the uneven color of the oxide film of aluminum alloy and aluminum.

The workpiece area is too large, the swinging in the groove is too large during the operation, the contact and renewal of the edge and the center part with the solution are too large, Resulting in inconsistent oxide film color. . Prevention: When the oxidation of the workpiece swing amplitude is small, static treatment can be, but when the solution temperature is too low prone to the map-like [url=http://gobimarathon.org/yard/718-synthetic-materials-patio-deck-platform.html]synthetic materials patio deck platform[/url] piebald, it appears unnatural.

aluminum clad part of the processing of some of the aluminum layer is damaged, was cut off, the outer aluminum is a high quality aluminum, the inner layer is covered by miscellaneous aluminum, two large differences between the aluminum, it is oxidized " Vitiligo "like spots. Customers often do not understand this phenomenon, manufacturers should do more to explain the work, explain the whole story, so as not to cause misunderstanding. Problems in process operation Alkali etching of the workpiece is not complete, and the original oxide film and dirt at the local area are not completely eliminated. Alkaline etching is not performed immediately after alkali etching, and the surface of the workpiece [url=http://gobimarathon.org/yard/717-Rustic-Outdoor-Picnic-Shelters.html]Rustic Outdoor Picnic Shelters[/url] remains alkaline. In contact with foreign body.
