Thanks to the strong growth in end-market demand for chemicals, electronics, manufacturing and metal materials, the global industrial gas giant recently delivered a satisfactory first-quarter earnings report. Air Liquide's sales revenue in the first quarter increased by 12% year-on-year to 3.5 billion euros ($5.1 billion). The company’s industrial gas and service division achieved sales revenue growth of 11% year-on-year to 3.2 billion euros, of which sales revenue from advanced economies increased by 8% year-on-year, while sales revenue from developing regions soared by 30% year-on-year. Praxair's first-quarter net profit rose 17% year-on-year to $398 million; sales revenue rose 11% year-on-year to $2.7 billion. Sales revenues in all areas of the company have increased, and profit growth is mainly due to the increase in both sales volume and sales price as well as increased productivity. Pratt & Company chief executive Steve Angel said: “In the first quarter, emerging markets led by South America and Asia saw double-digit growth, and North American business was also supported by the steady recovery of the US economy.†Praxair The profit target for this year has been raised from $5.25 to $5.40 per share to $5.35 to $5.45 per share. Angel said: "There are still many opportunities for new projects. In the first quarter we signed new industrial gas supply agreements in almost all major markets. This part of the orders means that the company will invest more than $500 million." German industrial gas giant Linde realized profit after tax rose 42% in the first quarter to 303 million euros, sales revenue rose 15% year-on-year to 3.3 billion euros, operating profit rose 19% year-on-year to 761 million euros. In the first quarter, Linde’s industrial gas division’s operating profit increased by 16% year-on-year to 727 million euros, and sales revenue increased by 14% year-on-year to 2.7 billion euros. Linde said that these figures reflect the global economic recovery in the first quarter, especially in emerging markets. Linde’s engineering division’s first-quarter operating profit rose 22% year-on-year to 62 million euros, and sales revenue rose 14% year-on-year to 591 million euros.
Aluminum plate is the thickness of above 0.2mm to below 500mm, more than 200mm width, length within 16m aluminum material called aluminum plate or aluminum sheet, below 0.2mm for aluminum,200mm width within the bar or bar (of course, with the progress of large equipment, the widest can do 600mm aluminum plate is also more).
Aluminum plate refers to the rectangular plate made of aluminum ingot rolling, which is divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium thick aluminum plate and pattern aluminum plate.
Aluminum plate is usually divided into the following two types:
1. According to the alloy composition:
High purity aluminum sheet (rolled from high purity aluminum with content above 99.9)
Pure aluminum plate (basically made of rolled pure aluminum)
Alloy aluminum plate (composed of aluminum and auxiliary alloys, usually aluminum Copper, aluminum manganese, aluminum silicon, aluminum magnesium, etc.)
Composite aluminum plate or brazed plate (special purpose aluminum plate material obtained by means of composite of multiple materials)
Aluminum clad aluminum sheet (aluminum sheet coated with thin aluminum sheet for special purposes)
2. Divided by thickness :(unit mm)
aluminum sheet (aluminum sheet) 0.15-2.0
Conventional plate (aluminum sheet) 2.0-6.0
Medium plate (aluminum plate) 6.0-25.0
Thick plate (aluminum plate) 25-200 super thick plate more than 200
Drawing aluminum plate: The manufacturing process of repeatedly using sandpaper to scrape the aluminum plate out of the line, the main process is divided into three parts: deester, sand mill, washing. In the drawing process of aluminum plate, the special skin film technology after anode treatment can generate a skin film containing the metal composition on the surface of aluminum plate, and clearly show each fine wire trace, so that the fine hair luster in the metal matte.
Aluminum oxide plate: aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, under specific conditions and external current, electrolytic aluminum plate formed. The anodic aluminum plate is oxidized to form a thin layer of alumina on the surface, the thickness of which is 5 ~ 20 microns, and the hard anodic oxide film can reach 60 ~ 200 microns.
PS aluminum plate (advertising aluminum plate, also known as printing zinc plate, newspaper plate) : that is, on the back of the printing pattern thickness of 025 or 03 materials of aluminum plate.
Mirror aluminum plate: refers to the aluminum plate treated by rolling, grinding and other methods, so that the surface of the plate presents the mirror effect.
Embossed aluminum plate can also be called aluminum embossed plate: on the basis of aluminum plate, after calendering and forming a variety of patterns on the surface of the aluminum products, widely used, mainly in packaging, construction, curtain wall and other aspects.
