The O state is the state of the aluminum plate. This is the product annealed in the factory. The same brand of aluminum alloy is divided into O states. The O-state aluminum plate is softer than the h 111 aluminum plate and is suitable for sealing the head. It is not easy to crack after hydraulic expansion. Then the following small series to explain in detail, what is o state aluminum plate?

What is O-state aluminum sheet?

1. The O state is the state of the aluminum plate. The O state is the annealed state, that is, the completely soft state, which is suitable for full annealing to obtain low-strength processed products. This is factory annealed product. The same brand of aluminum alloy can be divided into two different forms :O state and H state.

2. Aluminum plate thickness greater than 0.2 mm to 500 mm or less, width greater than 200 mm, length of 16 meters is called aluminum or aluminum alloy plate. Aluminum is 0.2 mm or less, width 200 mm or less or strips of discharge material.

3. Because the O-state aluminum coil is relatively soft, easy to bend and pull, it is mainly used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons and other industries. The rectangular plate of aluminum ingot rolling is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium thick aluminum plate and patterned aluminum plate.

4. Annealing state, that is, completely soft state, suitable for products with low strength in full annealing. The state of the aluminum plate is basically divided into five categories, and the composition of aluminum and aluminum alloys is divided into nine categories. Among them, aluminum and aluminum alloy are mainly used in series 1, 3, 6 and 7 series, and other series are unlikely to be used in actual use.

What are the causes and treatment methods of aluminum plate dyeing?

Aluminum plate is now used in life there are many industries, and aluminum plate in the color is no longer as monotonous as before, according to the color you want to color, and in the process of coloring, it is inevitable to encounter the situation of not dyeing color, so what is the cause and treatment of aluminum plate dyeing not coloring?

What are the causes and treatment methods of aluminum plate dyeing?

1, insufficient anodic oxidation film thickness: the solution is to check whether the anodic oxidation process is standardized, to see whether the temperature, voltage, conductivity and other factors are stable, if there is an anomaly, please adjust the specification accordingly, if there is no anomaly, the oxidation time can be appropriately extended to ensure that the film thickness is up to standard.

2, the PH value of the dye is too high: at this time, the PH value can be adjusted to the standard value of glacial acetic acid.

3, after oxidation, the workpiece is placed in the tank for too long: promote timely dyeing, if this has happened, the workpiece can be placed in the anodic oxidation tank or nitric acid neutralization tank appropriate activation treatment and then dyeing, the effect will be very good.

4, the choice of dye has been decomposed or mildew: at this time to replace the dye, choose the appropriate dye.

5, the oxidation temperature is too low, resulting in dense skin film: the oxidation temperature can be appropriately increased.

6, poor conduction: the anode copper rod or cathode lead plate may be in poor contact with the batch of poor conduction. Pay attention to cleaning anode copper rod and cathode lead plate to ensure good conduction.
