Polishing tank is a type of tank with a highly polished surface, mainly characterized by the following features:
1、 Good hygiene performance
1. Easy to clean
The inner surface of the polished storage tank is very smooth with relatively low roughness, which makes the interior of the tank almost free of gaps and depressions. When used in industries such as food, beverage, and pharmaceuticals, this smooth surface can effectively prevent the accumulation of dirt, microorganisms, and other contaminants. For example, in dairy processing, the fat, protein, and other components in milk are not easily attached to the tank walls. When cleaning, only a small amount of cleaning solution is needed, and the interior of the tank can be cleaned through simple rinsing and wiping, greatly reducing cleaning costs and time.
2. Meet hygiene standards
For industries with high hygiene requirements such as pharmaceutical production and food processing, polished storage tanks can meet strict hygiene standards. Its smooth surface can prevent bacterial growth and will not contaminate the stored substances. During the storage process of drugs, some injections, eye drops, and other drugs that require high purity can be stored in polished storage tanks to ensure that the quality of the drugs is not affected by external factors and meets the requirements of Good Manufacturing Practice (GMP).
2、 Enhanced corrosion resistance
1. Physical protection function
After polishing, a dense protective film is formed on the surface of the tank, which can to some extent prevent external corrosive substances from directly contacting the material of the tank body. For example, in the chemical industry, when storing corrosive liquids such as dilute acid, dilute alkali, etc., polishing the protective film of the storage tank can delay the corrosion process and extend the service life of the tank.
2. Improved chemical stability
For certain special storage substances, polishing the surface properties of storage tanks can reduce the occurrence of chemical corrosion. For example, when storing high-purity organic solvents, the chemical stability of the polished tank surface can prevent chemical reactions with the organic solvent, ensuring that the chemical properties of the stored substance remain unchanged while also protecting the structural integrity of the tank itself.
3、 Guarantee of appearance and quality
1. High aesthetic appeal
The polished appearance of the storage tank is as bright as a mirror. In some occasions where there are requirements for the appearance of the equipment (such as display type brewing workshops, beverage production workshops, etc.), it can enhance the overall level of the production environment. Its smooth surface can also be marked with labels, scales, and other markings, which are clear and durable, making it convenient for staff to operate and manage.
2. Good visibility of material quality
Through polishing treatment, any minor defects on the surface of the storage tank, such as sand holes, cracks, etc., are more easily detected. In the quality inspection process after the completion of tank manufacturing, this visibility helps to detect problems in a timely manner and ensure the quality of the tank. Meanwhile, during use, it is also convenient to observe changes on the surface of the storage tank and promptly identify potential safety hazards.
4、 Maintain good material performance
1. Reduce the mixing of impurities
Due to the smooth inner surface of the polished storage tank, there are rarely any material surface debris mixed into the stored material during storage. For example, in the storage of electronic grade chemicals, these high-purity chemicals have relatively low requirements for impurity content. Polishing storage tanks can effectively prevent the tank's own materials (such as metal shavings) from entering the chemicals, ensuring the purity of the chemicals.
2. Ensure stable material quality
For some materials that are sensitive to temperature, light, etc., polishing tanks can provide a relatively stable storage environment. For example, in the storage of cosmetic raw materials, some easily oxidizable and decomposable ingredients can be well protected in polishing tanks, and their smooth surfaces will not adsorb or catalyze material deterioration reactions like rough surfaces, thus ensuring the stability of material quality.
