How many shapes of metal decorative strips? Different shapes have different functions, including T-type pressure strips with four-sided slits on the sound-absorbing board, several types of pressure strips, doorway window openings, yin and yang angle closures, right angle yin and yang angle pressure strips, L-shaped closing strips with edges. The sound-absorbing board used is different, and the use of the strip is different. The production process of stainless steel tile edging metal decorative strips mainly includes three processes: casting, extrusion and coloring. Among them, coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer printing and other processes. 
Anodizing treatment in aluminum oxidation processing:
(1) The general principle of anodic oxidation treatment, the general concept of anodizing the anodized film in the tile trim manufacturers electrolyte solution of aluminum or aluminum alloy products, through the electrolysis process, the alumina film formed on the surface, called anodized aluminum and aluminum alloy processing. Materials with high chemical stability in the electrolyte are cathode devices such as lead, stainless steel, aluminum, etc. The principle of aluminum anodizing is essentially the principle of water electrolysis. When the current is passed, hydrogen is released at the cathode, anode, precipitation; Oxygen is not only an oxygen molecule, including atomic oxygen (O) and ionic oxygen, which usually react with molecular oxygen. The anodized oxygen precipitation of aluminum, the formation of anhydrous alumina film, the oxygen produced is not all reacted with aluminum, partially precipitated gas. 2 choices of anodic oxide film, anodic oxidation electrolytic solution growth is a prerequisite, the effect on the film should be the dissolved electrolyte. But this is not to say that the properties of the membrane oxide film that are dissolved in the electrolyte anodized in anodic oxide can be the same at all.
(2) Cavitation, type anodic oxidation, 40 interference membrane 3 of the anodizing current form is china tile trim divided into: DC anodizing, alternating current anodizing, pulse current. Press electrolytes: sulfuric acid, oxalic acid, chromic acid, organic acid solution of naturally colored anodized mixed acid and sulfonic acid group.
Aluminum oxidation processing is divided into: ordinary film, dural film (film), barrier layer, anodized ceramic film, bright modified layer, semiconductor influence.
