Polyethylene plastic storage tanks can store and react most inorganic acids, alkalis, salt solutions and most organic solvents, and can partially replace stainless steel, titanium, nickel, high-grade alloy steel and other materials. Plastic storage tank products comply with the dangerous goods storage and transportation regulations It is an ideal storage container for storing reaction chemical corrosion solutions and clean solutions. Today, the editor will lead everyone to understand the seven characteristics of plastic storage tanks.
一. Due to the excellent performance of linear low-density polyethylene (LLDPE) and the special structure of the plastic storage tank, the service life is more than 15 years.
二. The plastic storage tank (PE) has good integrity in one-time molding, no welds, never leaks, impact resistance, high tensile strength, good oxidation resistance and aging resistance, and it meets hygienic food standards.
3. The chemical resistance is very excellent. Except for a few solutions that can swell it, it can almost be resistant to most substance solutions.
4. Plastic storage tanks have the characteristics of internal and external corrosion protection, and can be placed in a highly corrosive environment.
5. Generally, the operating conditions of Aoen storage tanks are normal temperature and normal pressure; in special cases, the operating conditions of storage tanks can be temperature less than 70℃ and hydraulic pressure less than 1kg/cm2.
Six. Rotomolding anticorrosive polyethylene plastic storage tanks have great advantages in large-scale, large-capacity and large-volume products. Although they are large in size, they still maintain the characteristics of one-time molding integrity, which is not achieved by other storage tank processes. Place.
Seven. Compared with traditional anticorrosive storage tanks, the price is low, and the performance-price ratio is high.
The above is the relevant content of the characteristics of polyethylene plastic storage tanks organized and introduced by the editor today. I hope it will be helpful to everyone. If you are interested in the knowledge of plastic storage tanks, please call our company or follow our website at any time. We will provide you with the best quality service!
Small storage tank, great use, Changzhou Aoen storage tank
1. Hydrochloric acid
Hydrochloric acid is the common name of hydrochloric acid. It is an aqueous solution of hydrogen chloride (HCl) gas. The solute is a strong monobasic acid. A common chemical and chemical raw material, there are many applications, including household cleaning, food additives, rust removal, leather processing, etc. The main component of gastric acid is also dilute hydrochloric acid. Hydrochloric acid is not only an important product of salt chemical industry, but also an important raw material for the production of silicon materials. The world's annual output of hydrochloric acid is about 20 million tons. Commercially available hydrochloric acid generally has a mass fraction of 37% (about 12mol/L). Need to store this liquid, the solubility should reach more than 38%, the temperature is 0-80 degrees, steel-lined plastic storage tanks can be used.
Sulfuric acid (chemical formula: H?SO?). Sulfuric acid is the most active binary inorganic strong acid. It can react with many metals. It crystallizes at 10.36℃. The mass fraction is generally around 75%. Polyethylene storage tanks can be used, but the purity is 95%. Carbon steel storage tanks or stainless steel storage tanks must be used for the above.
Ethanol (chemical formula: C2H5OH (C2H6O), commonly known as alcohol, is a flammable, volatile, colorless transparent liquid at room temperature and pressure. Its aqueous solution has a special, pleasant fragrance and slightly irritating Properties, boiling point: 78.4 °C, when the solubility is 30%, steel-lined plastic storage tanks can be used.
Chlorobenzene is a colorless liquid with a boiling point of 131.7°C. During the First World War, it was mainly used to produce picric acid required for military explosives. From 1940 to 1960, it was used in large quantities to produce DDT (DDT) insecticide. After 1960, DDT was gradually replaced by other pesticides with high efficiency and low residual toxicity, and the demand for chlorobenzene was declining. Polyethylene tanks cannot be used to store the liquid, but carbon steel tanks, stainless steel tanks, and glass fiber reinforced plastic tanks can only be used.
Acetic acid is acetic acid, also called acetic acid (0%-38%), glacial acetic acid (98%), chemical formula CH3COOH, is an organic monobasic acid, is the source of sour taste and pungent smell in vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid with a freezing point of 16.6°C (62°F), and becomes a colorless crystal after solidification. Although acetic acid is a weak acid based on its ability to dissociate in an aqueous solution, acetic acid is corrosive and its vapor is irritating to the eyes and nose. The annual worldwide demand for acetic acid is about 6.5 million tons. About 1.5 million tons are recycled and reused, and the remaining 5 million tons are made directly from petrochemical raw materials or made through biological fermentation. Polyethylene tanks can be used to store acetic acid, but polyethylene tanks cannot be used for glacial acetic acid.
The editor first introduces the storage of the above 5 kinds of liquids, so everyone should listen to the guidance of professionals when choosing storage tanks, and do not choose blindly~
