Tar is a kind of oil product, which is formed by a series of organic chemicals exposed to air for a long time, and is widely used in engineering fields such as construction and road construction. Because of its strong viscosity and adhesion, if it is not handled in time, it will have a greater impact on the environment and affect the quality and durability of construction projects. So how to quickly and efficiently clean tar becomes very important. This article will introduce several cleaning methods of tar.

method one: hot water method. Use high-temperature water to rinse or soak to soften the tar and be easy to remove. Heat the water to 100 ℃-120 ℃, sprinkle the oil-stained ground, and scrape off the tar after softening.

method two: regular cleaning agent method. Apply a high-concentration household cleaner or car detergent to the tar, and then gently wipe it with a cleaning cloth. It should be noted that you must choose a detergent with good oil removal performance.

method three: bioactive agent method. Bioactive agent can remove tar through biological reaction, which is a kind of green cleaning method. Add bioactive agent, in the appropriate temperature, water level, time and other conditions, by cell metabolism decomposition of tar, thereby removing the impact of tar.

method four: mechanical cleaning method. Mechanical cleaning method is one of the most commonly used cleaning methods, including high-pressure water jet cleaning, sandblasting cleaning, brushing and so on. Among them, high-pressure water jet cleaning (commonly used in roads and other ground) has the advantages of large water volume, high pressure, and fast cleaning speed. At the same time, sandblasting cleaning is also an efficient method of cleaning tar, which can be used to spray high-speed abrasive grinding sludge to remove it.

method five: chemical cleaning method. The chemical cleaning method is a method of cleaning the tar with a specific chemical solution or surfactant. After a certain chemical reaction, tar can not adhere to the surface, not easy to adhere, in order to clean. This method for high viscosity of the tar can play a better cleaning effect.

When cleaning tar, you need to pay attention to the following points:

1. Timely cleaning: Once tar pollution is found, it should be cleaned as soon as possible to prevent the risk of environmental pollution caused by waste accumulation.

2. pay attention to safety: tar is not only high viscosity, but also irritating and toxic. When cleaning, be sure to wear protective equipment, avoid direct contact, maintain a good ventilation environment.

3. Choose the right cleaning tool: Be sure to choose the cleaning tool according to the degree of pollution and the characteristics of the site.

4. Be patient: Cleaning tar requires patience, don't worry, clean it as soon as possible.
