Sheet metal finish

Aluminum sheet metal is one of the most common materials at present. Before aluminum is used, some sheet metal finishes are applied to its surface to prolong its service life. So, what are the sheet metal finishing processes of aluminum alloys? The following editor will introduce to you four common 4 x 8 aluminum sheet metal surface finish treatment processes. 1. High gloss polishing Use a precision engraver to work on the surfaces of sheet metal so that those surfaces show bright areas. This kind of processing technology is generally used on mobile phones and high-end TVs, especially those high-end TVs, which make the appearance of the TV more fashionable and show a sharp sense of technology.
2. Sandblasting This process uses the impact of high-speed sand flow to clean and texture the surface of the aluminum plate, so that the surface of the aluminum alloy can obtain a certain degree of cleanliness and roughness. The mechanical properties of the aluminum sheet can be improved by sandblasting, which not only improves the fatigue resistance of the aluminum alloy product, but also increases the adhesion and durability of the aluminum alloy product and the surface coating. 3. Brushed finish This process refers to repeatedly sanding and scraping the surface of the aluminum plate with sandpaper until the lines are scraped out. There are many types of brush painting such as straight, random, straight, spiral, etc. After brushing, each line can be clearly seen on the metal surface of the aluminum sheet. At the same time, the metal frosting of 1/8 aluminum sheet products will show a fine hairline luster, making aluminum alloy products more fashionable and scientific. 4. Mirror polishing This process refers to the use of mechanical, chemical or electrochemical methods to polish the surface of aluminum plate metal veneer products to reduce the surface roughness of aluminum plate metal products and make the surface of aluminum plate products more smooth and bright. The surface effect of mirror polished aluminum products is close to that of stainless steel, which can give people a very high-end fashion visual effect.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands
