How to Distinguish Between True and False and Use Taboos of Aluminum Aluminum-WJW Aluminum Supplier Aluminum

How to distinguish the authenticity of Ya Aluminum.

1. Look at the smoothness.

Yalum aluminum is squeezed by aluminum rods through molds. The fake profiles are generally used as raw materials with waste aluminum. The material contains a lot of impurities. The squeezing will cause different degrees of damage to the mold. It is rough, not smooth, and even marks. The profiles produced by scrap aluminum cannot meet the standards in the strength, hardness and other physical effects. The feel is more comfortable.

2. Look at the smoothness of the smoothness of the sketch of Asian aluminum. You can see that it is shiny and shiny by the horizontal section of the aluminum aluminum. This is easy to identify with the naked eye.

3. Packaging of aluminum materials. Asian aluminum is environmentally friendly cowhide packaging, which is very reasonable and economical, and effectively protects the surface of the aluminum. The packaging of sub -aluminum aluminum will be affixed with exclusive qualification certificates.

4. Looking at chemical ingredients, the chemical composition of fake aluminum is unqualified. In the product, a large amount of miscellaneous aluminum and waste aluminum are mixed, which greatly reduces the cost.

5. Looking at the thickness of the oxide film, the national standard stipulates that the thickness of the oxide film of the building aluminum should not be less than 10um (micron), the thickness of the counterfeit aluminum is not enough, the surface of the aluminum profile is easy to rust and corrodes. 2-4um, because each ton of alumina film is reduced, the cost of power consumption per ton can be reduced by about 150 yuan per ton.

The use of aluminum products has the following taboos:.

1. Do not use aluminum products to be acidic or alkaline, if juice, wine, soy sauce, vinegar, etc.

2. Avoid stirring eggs in aluminum products. When the egg whites encounter aluminum, it will become gray -white. When the egg yolk encounters aluminum, it will become green, and porcelain products are better containers stirring eggs.

3. Do not use aluminum products to store flour for a long time. After the starch in the flour is fermented, organic acids will be produced, which will have corrosion effects on aluminum. The amount of water in the air will produce carbonate with water in the air. The erosion of acid, water and carbonate is destroyed and rust.

4. Do not use aluminum pot for a long time to put food. The corrosion resistance of aluminum is poor. Alcohol, alkali, acid, and salt can have a chemical reaction with aluminum. If people eat meals for a long time in aluminum pot, they will treat people's body Health causes damage.

5. Avoid using aluminum decoction. Use aluminum products to make the drug fail, and it may also generate toxic substances that are harmful to the human body.

6. Avoid using iron aluminum cooking utensils. Mixing iron aluminum cooking utensils is more common, but this usage is greatly harmful to health. After the iron and aluminum impact, after rubbing, the softer aluminum will fall into many powder particles. These The particles enter the human body with the meal, so that the aluminum volume in the body increases and forms chronic accumulation. When it is accumulated to a certain amount, it will cause harm to the human blood and brain function, aluminum material.
