61789-60-4 - Introduction
Pitch is a black gelatinous substance, the main component is hydrocarbons. It has the following properties:
1. Higher density: Since the density of Pitch is about 1.1 to 1.4g/cm3, it is heavier than most liquids.
2. High viscosity: Pitch has high viscosity, that is, the viscosity is very strong. This makes it appear as a heavy liquid at room temperature.
3. Insoluble in water: Pitch is a hydrophobic substance, almost insoluble in water, but miscible with many organic solvents.
Pitch has a wide range of uses, including:
1. Road construction: Pitch is widely used in road construction and maintenance. It can be used as the main component of road surfaces and asphalt roads, providing waterproofing, wear resistance and durability.
2. Building materials: Pitch is also used in the construction industry as a waterproof layer, insulation material, roof covering material, etc.
3. Pitch concrete: Pitch concrete is a material mixed with mineral aggregate, Pitch and other additives, which is used in the construction of roads, parking lots and airport runways.
The method of making Pitch mainly includes:
1. Crude oil refining: in the refining process, heavy crude oil is fractionated and processed to produce Pitch.
2. Residue processing: Residue is the residue generated in the oil refining process. After heating, distillation and other chemical treatments, Pitch can be obtained.
The safety information for Pitch is as follows:
1. Contact with Pitch may cause skin irritation and allergic reactions. Wear appropriate personal protective equipment, such as gloves and protective glasses.
2. Inhalation of Pitch smoke may cause irritation to the respiratory tract. When using Pitch, ensure a good ventilation environment.
3. Avoid exposing the Pitch to a fire source or a high-temperature object to prevent it from burning or causing a fire.
4. For the handling and storage of Pitch, the corresponding safety operation procedures should be followed to ensure personal safety and environmental protection.
