The harm of moisture on the electrode: The welding of the welding rod in the welding rod factory and the baking treatment before use are to reduce and effectively prevent welding defects. Alkaline electrodes easily absorb moisture from the outside environment, causing the electrode to become wet. During welding operations, moisture can cause defects such as blowholes in the weld.
The surface of the welding consumables has a layer of protective coating. The primary role of the electrode coating is as follows: 1. The welding seam is protected from the formation of inert gas which can effectively isolate the outside air and prevent excessive oxidation of the high-temperature metal and reduce the pressure of the weld seam. 2. The electrode coating contains an arc stabilizer that stabilizes the welding arc. If the alkaline electrode is exposed to a humid environment for a long time, the skin absorbs too much moisture. During welding, the electrode burns and the core resistance heats up in the city. When the water evaporates too quickly, the fine skin will crack. Induced electrode does not constitute excellent protection!
After the welding rod gets wet, it will indirectly cause more slag inclusion and more bubbles when the worker welds, resulting in weak welding strength. The current is poorly controlled and the burned metal is burned. Welding electrodes that have been wet have an extremely bad influence on the welding processability during welding, and arc extinguishing occurs when the moisture absorption is large. It is easy to cause slag, not to cover the molten pool well, and to affect the mechanical properties of the weld metal, which will seriously affect the personal safety of personnel.
Dehumidifiers of air dehumidifier manufacturers Kawashima Dehumidifier Friendly Tips: Wetness is a major factor in the damage of various welding consumables in the process of stockpiling of consumables. It is essential to use dehumidifiers for effective moisture-proof dehumidification and general corporate welding. Material storage area is about 20-30 square meters, therefore, only need to use Kawashima DH-890C welding material dehumidifier, and the quality of the product welded with good quality welding material will be higher!
In the manufacturing of automobiles, ships, and electrical appliances, the application of various welding materials is very extensive. There are strict management systems for its production, storage and transportation; the quality of welding consumables directly affects the quality and safety of welding products. Whether it is in the welding material manufacturing enterprise or in the machinery manufacturing industry, the safe storage of various welding consumables is a top priority;
Welding materials are easily damp in wet conditions, while wet welding materials will affect the quality of welding; therefore, Kawashima DH-890C welding material dehumidifier professional humidity control is generally required in the welding material library. The equipment has strict humidity control so as to achieve the purpose of moisture-proof and dehumidification!
The welding material library dehumidifier is developed for the humid and bad loop mirrors and the air humidity is too high, can effectively reduce the humidity of the ambient air to improve the wet life and production and storage environment, so that it reaches the ideal state of the best air humidity.
Waste Tire Pyrolysis Plant
The background and signification of research this waste tire pyrolysis program
As tire has been used for all other industry widely, they are playing an important role in the development of our economy, but waste tire did not easy to broken after being used and it becomes a big pollution for our environment .Therefore it is urgent to process those waste material without pollution.
In addition ,as the fastest development of world economy ,the shortage of petroleum will be urgent more and more , even the expert had stated that it will have no petroleum recover in earth after 15years later, so searching the new resource becomes an issue which is concerned by all the countries of the world.
1.Working process Of waste tire pyrolysis plant:
First, the raw materials are put into the reactor, and then seal the feeding in door, later start the machine and the reactor will be rotating and heated by coal, natural gas, wood or electricity. When the temperature reaches the degree of 250 to 280, we will get the crude oil, the oil steam will be continuous produced until the temperature reaches 350-460 C; oil steam will flow through oil gas separator, light component will enter the condensers and meanwhile the heavy oil will be discharged automatically into in heavy oil tank. The liquefied part will be condensed as crude oil, and the part which cannot be liquefied will be transferred by the water seal back to the burning chamber to be reused as heating material.
