Dear Current Administrators of TBA, Stop erasing posts and topics. All of you. As a regular of TBA who loved it dearly, you have no idea how much it kills me that so many topics were left to the trash without member consent. And it wasn't just drama posts -some of you deleted any post that you didn't like, from roleplays, from anything...you deleted the entirety of A Very Potter Roleplay, as an example. As the creator of that roleplay, I realize it was somewhat of a failure, but the fact that it was erased without my consent is upsetting, and there were a few members who enjoyed it. I realize that there were some things posted on TBA that many of us are not proud of. Drama and the like. But even with that drama, TBA was so, so, important to me, and others. Yet, certain moderators have ignored this and have erased topic upon topic -that showed in the Administrator history. Even if you say it was only a single topic or a single post, the forum has been trimmed down. You say this is only "cleaning up the forum," but it's erasing our history, and I won't stand for it. To those of you who've returned to this forum only to remove things periodically, please stop. It simply isn't fair to those of us who are nostalgic and like looking back, and I know I don't speak of myself alone. With all due respect, LL.

<p>Aluminum alloy and aluminum parts in the pre-processing process, the need to pay attention to the problem: Although the surface of the fine processing of the original oxide film was born at the beginning, easier to remove, but oily heavy, especially in and around the hole (due to machining The process of lubrication needs to be added), this type of workpiece must be home depot mobile home deck kits cleaned with organic solvents, if not directly with alkaline cleaning is difficult to remove the oily heavy net, and fine processing can not withstand the strong alkali corrosion for a long time, the result will affect the workpiece The roughness of the surface and tolerances, eventually there may be waste. </p> <p>aluminum alloy and aluminum casting molding parts in the pre-treatment process need to pay attention to the problem. Casting parts are not all machined surface machining, leaving the surface without casting process is too thick oxide layer formed during casting, and common wood plastic composite material some also sand, this time should be first machined or sandblasting method to remove This part of the original oxide film, or after caustic and then processing, the only way to not only net raw parts of the raw oxide layer, but also to avoid the size of the machined parts to change the size. </p> <p>aluminum alloy and aluminum after heat treatment or welding process parts in the pre-treatment process need to pay attention to the problem: put cesium Arts requirements, the workpiece into the heat treatment or welding process before the need for organic solvent cleaning, in addition to net surface oil, but At present, generally can not do this, so the surface of the workpiece to form a layer of oil-burning coke, this layer of coking in the organic solvent is Pvc Ceiling Panels in Ghana What Do They Do in Big difficult to remove the net, if soaked in lye will cause local corrosion, pitting or cause Uneven, seriously affecting product quality.</p>
