Bucket elevators should be used with attention problems

Bucket elevator is the metal and the corrosive environment of the physical and chemical interactions, change in properties of the metal, causing the metal, and the composition

system environment may be damaged reactive phenomenon.
Corrosion is a chemical change, corrosion of many conditions, such as sulfuric acid corrosion of an object is to be in H, O prolapse in a 2:1 ratio, because the molecule of H2O

H, O ratio is 2:1, the corrosive sulfuric acid, also known as dehydration; Another example NaOH corrosion, corrosion of the object it will destroy proteins, corrosive effects

from Seoul
Corrosion can be divided into two types of wet etching and dry etching. Wet etching refers to the metal in the presence of water corrosion, refers to the dry etching in the Telescopic belt conveyor

absence of liquid water in the dry etching gas. Because the atmosphere generally contain water, chemical production is also often deal with various aqueous solutions, so wet

etching is the most common, but the high temperature operation, the harm caused by dry etching can not be ignored.
However, for the stainless steel bucket elevators selection factors to be considered are:
One, people use any metallic material items are very eager to have super corrosion resistance, so that also extended the period of use, this corrosion resistance is determined

according to human standards, people regularly use, but can not receive its constraints, which reflects its corrosion resistance. Now on the corrosion resistance of stainless

steel are very seriously, the corrosion resistance of stainless steel is currently more than 10 criteria used to select which one as corrosion resistance requirements, to

consider the equipment, the Ministry of the characteristics of a (thickness, size) . Length of life, quality of products (such as impurities, color, purity) and other gravity conveyor

requirements, in general, the process requires the use of smooth and glossy or size precision equipment, instrumentation and components, you can choose from 1 to 3 standards;

pair requires close coordination , does not leak or require the use of long length-limited equipment, components selected from 2 to 5, for the less demanding maintenance easy

life is not very long or require equipment, components can be selected from 4 to 7, in addition to a special exception, the use of stainless steel under the conditions of the

corrosion rate of more than 1mm are generally not used, be pointed out, 10 standard for generating localized corrosion is not applicable.
2, we often say to this metal product is good, most of the first time to consider whether it is corrosion-resistant, corrosion-resistant extent. Currently manufacturers bucket

elevator mostly stainless steel products, but which also has a lot of defects. However, considering these factors must also consider how we use it, and apply it to what the

environment in which. Conditions of use is crucial, including normal conditions (medium, concentration, temperature, impurities, pressure and flow rate constant), no matter how

corrosion resistance, are not held in any environment either to corrosion of metal, the main is a matter of degree. Such as stress corrosion pitting, etc. How then consider less

sensitive; localized corrosion of stainless steel more resistant to general corrosion in corrosive environments well occur, often leading to localized corrosion of stainless

steel equipment, parts suddenly destroyed, its harmfulness far much larger than the general corrosion.
3, we use the process, we have to consider the use of the environment, use of the media in some water and chemical medium, we should note that because the choice was to make

more general consideration is resistant to corrosion, but in practice, For much more localized corrosion phenomena. Such as stress corrosion pitting, etc. How then consider less

sensitive; localized corrosion of stainless steel more resistant to general corrosion in corrosive environments well occur, often leading to localized corrosion of stainless

steel equipment, parts suddenly destroyed, its harmfulness far much larger than the general corrosion.
4, in some conditions of use, will encounter other situations, for example in the use of the bucket elevator in the process of product components is easy because parts corrosion

and failure, then we should timely analysis lead to corrosion of the reasons, the right remedy in a timely manner remedy, so that our products will wait until the maximum value

in use.
