1. Introduction of aromatic solvents
Aromatic solvent is a special chemical substance with high chemical and thermal stability, which can dissolve a variety of organic substances, so it has a wide range of applications in the industrial field. However, the dangers of aromatic solvents should not be overlooked. Its vapor is irritating and toxic, and long-term exposure can cause harm to the human body; At the same time, aromatic solvents have a high boiling point and dissolution capacity, and also have the characteristics of flammability and explosiveness, and are easy to form a first-class mixture when in contact with air, which brings potential safety hazards to the transportation process. Therefore, when selecting the material of the conveying hose, the characteristics of aromatic solvents must be fully considered to ensure safety and reliability.
Choosing the right delivery method is critical for the delivery of aromatic solvents. In general, aromatic solvents can be transported by pipeline, tanker or pump. When choosing a delivery method, factors such as the chemical properties of the aromatic solvent, the distance to be conveyed, the volume to be conveyed, the materials of the pipes and equipment, and the safety of the operator need to be considered.
Second, the application industry of aromatic solvents
Aromatic solvents are widely used in many industries, including but not limited to the following:
1.Chemical Industry:Aromatic solvents are used to dissolve a variety of chemicals and materials during synthesis, refining, and processing. For example, benzene can be used as a solvent in organic synthesis, and toluene can be used in processes such as solvent extraction.
2.Petrochemical:Aromatic solvents are one of the important components of petrochemical products and are widely used in refining, refineries and chemical plants. They can be used as solvents to separate and purify different components in petroleum.
3.High-tech field:Some high-tech industries such as semiconductor manufacturing, liquid crystal displays, and solar cell production also use aromatic solvents. These industries require highly pure and high-temperature stable aromatic solvents to ensure product quality and performance.
4.Cosmetics & Pharmaceuticals:Certain aromatic solvents are also used in the production of cosmetics and pharmaceutical products. For example, ingredients such as ethyl acrylic resins and polyvinyl alcohol often use benzene or toluene as solvents. In addition, some drugs also need to be dissolved and mixed under specific conditions.
In conclusion, aromatic solvents have a wide range of applications in many industries, and their unique properties make them indispensable raw materials and intermediates.
3. The basis and principle of material selection of aromatic solvent conveying hose
Hose conveying, as an intermediate for aromatic solvents, requires the following characteristics:
1.Chemical Resistance:Aromatic solvents are corrosive to many materials, so grades with good chemical resistance are preferred. For example, polyurethane, fluoroelastomer, silicone rubber, etc. have good corrosion resistance.
2.Abrasion resistance:During the conveying process, the inner diameter, outer diameter and wall thickness of the hose wear and tear is high, and it is necessary to choose a material with high wear resistance. For example, polyurethane, neoprene, nylon, etc. have good anti-wear properties.
3.Tensile Strength:In order to ensure that the conveying hose is not easy to break under high pressure, high temperature and other conditions, it is necessary to choose a material with high tensile strength. For example, steel wire braiding, high-strength fiber weaving, etc.
4.Heat resistance:Aromatic solvents are prone to decomposition and polymerization at high temperatures, so the conveying hose needs to have good heat resistance. For example, polyurethane, silicone rubber, etc. have good heat resistance.
5.Environmental performance:When choosing materials, we should fully consider their environmental performance to avoid pollution to the environment. For example, choose polymer materials that are biodegradable.
