Linear light kit manufacturer how to judge the stand or fall of industrial aluminum extrusion method
industrial aluminum is a kind of aluminum as the main composition of the alloy material, aluminum rods by hot melt extrusion to get different cross section shape of aluminum material, but the different proportion of added alloy, the mechanical properties of the production of industrial aluminum and application field are also different, how can buy good quality industrial aluminium profile?1, aluminum manufacturers - - - - - - Large aluminum plant, raw materials, production technology standards, strict quality control, high processing fee is more than the small manufacturer, toll fee can vary - 2000 3000 / ton. To reduce the 2 - 3 yuan/kg. In recent years, with the level of industrial, aluminum industry is becoming more and more popular. Sales also presents the diversification, price six to one. Unknown customer will only choose industrial aluminum sales company from the lowest price. Forcing some companies adhere to quality first from a low cost of raw material and processing, ensure the sales market turmoil has become increasingly obvious. 2, chemical composition, incorporation of a large number of miscellaneous scrap aluminum, industrial aluminum can greatly reduce the cost, but can lead to aluminum industrial chemicals is unqualified, seriously threaten the safety of engineering. 3, the thickness distribution of roughly the same size drawings, as well as the section size, width, center hole, but wall thickness difference is very big, also can be quite different, the weight of the each price also corresponding large gap. In addition, the low industrial aluminum can reduce some of the closing time, reduce the chemical reagent consumption, lower cost, but the material corrosion resistance is reduced greatly. Jinan industrial aluminum extrusion 4, thickness of oxide film - - - - - - Thickness is not enough, aluminium surface is easy to rust and corrosion. The national standard of construction and industrial aluminum oxide film thickness should be not less than 10 um ( Micron) 。 Some attribute name, address, production license, certificate of industrial aluminium profile, the thickness of the thin film is 2 to 4 um, some even without film. Experts estimate that each reduced by 1 um thickness of oxide film, can reduce the power consumption per ton of material 150 multivariate.
