Storage period of aluminum after cleaning

Aluminum alloy metal surface in a variety of heat treatment, mechanical processing, transportation and storage process, will inevitably be oxidized, resulting in a layer of uneven thickness of the oxide layer. At the same time, it is also susceptible to various oil pollution and adsorption of some other impurities. Because of this, the maintenance and management of aluminum alloy metal has become a worry for many people. After the metal surface is polluted by oil and adsorbate, a thin oxide layer will be formed on the surface, which can be cleaned with aluminum cleaning agent or with ultra wave machine. For severely oxidized metal surfaces and metals with thicker oxide layers, mechanical treatment should be carried out first, and then chemical treatment. Pass

{Cleaning agent for aluminum} Pretreatment method

{aluminum cleaning agent} pretreatment method 1. chemical pretreatment 1, alkali etching method this is the most common method. The surface after alkali etching is bright and delicate. In the past, China has commonly used alkali etching method to eliminate extrusion lines, but this method of aluminum consumption is too high, Japan used AL(OH)3 recovery device, to get better results and benefits. However, in our country due to high investment in equipment and extrusion machine tonnage mismatch and other reasons, can not be promoted, I mostly use the European method to use corrosion inhibitors. The advantage of this method is to make the aluminum surface more refined, the disadvantage is that the waste discharge will smell bad in the future to meet the environmental requirements. 2, the prototype of acid corrosion technology

How to choose the right metal cleaning agent

It is very difficult to take into account high quality, high efficiency and low cost in metal surface cleaning, because it involves many problems and is very complex. The most important problems are the efficiency and price of cleaning agents, the energy consumed in the cleaning process, the complexity and reliability of construction equipment, the efficiency and cost of labor productivity, as well as many problems such as environmental protection, waste treatment and safe production and construction. Since there are many surface cleaning processes and methods available for consideration, economical and practical cleaning methods should be selected on the premise that they can meet the production needs and achieve the cleanliness of the pretreatment requirements. Resibo today to share with you a

[Ruibao Cleaning Agent] Why did antirust oil fail to prevent rust?

Anti-rust failure will produce a very huge loss, especially precision parts anti-rust, if the anti-rust packaging failure will cause batch scrap. But the reasons for the failure of rust prevention are often puzzling to the craftsmen. The main reasons for the failure of anti-rust of precision parts 1. The quality of materials such as anti-rust grease and gas phase anti-rust agent used is unqualified, or the validity period has been exceeded. This will cause rust of the parts after the batch anti-rust packaging. Therefore, all kinds of anti-rust materials must be inspected, qualified materials can be used. 2. The metal surface is not cleaned or exposed to corrosive media. For example, the parts are not in accordance with the process before the anti-rust oil is applied.

[aluminum cleaning agent] cleaning agent manufacturers teach you aluminum cleaning precautions

Aluminum profiles in the production process, due to the need for molding, easy release, will use a variety of isolation additives. In the subsequent processing process, it is necessary to remove the release agent and grease attached to the surface. However, due to the characteristics of aluminum alloy, once the cleaning agent is selected and handled improperly, it will cause damage to the surface of aluminum alloy production, and even lead to discoloration and corrosion. Therefore, it is necessary to select the appropriate aluminum cleaning agent for the performance of aluminum, and at the same time, the following items should be paid attention to when cleaning aluminum: 1. The selection of degreasing agent Because the cleaning agent effect of a single component is poor, multi-component is generally used in the production of industrial aluminum profiles.

Cleaning agent manufacturers teach you how to clean die cast aluminum?

Die casting aluminum is a kind of aluminum alloy product casting process with high technical requirements and wide application. Die-cast aluminum products are of good quality, high precision, and smooth surface, and can usually be used directly after casting. Although die-cast aluminum can be used directly after casting, it must be a process in actual processing and production, that is, surface cleaning. After the processing of die-cast aluminum is completed, the surface will remain in the production of oil stains and other stains, these oil stains must be removed before use. Although it seems that only the surface of the oil, grinding oil and other residues cleaning, but this step is absolutely not sloppy, one is the surface of the residue
