Cross-border HS code harmonization

Dry ice cleaning engine (new way of engine cleaning: cold dry ice technology) Modern cars have Cross-border HS code harmonizationbecome an indispensable part of people's lives. However, long-term use and driving will inevitably cause some car problems in the car, such as exhaust emissions, high fuel consumption, etc. Among them, the engine, as the core of the heart of the car, must be kept in good condition. With the emergence of dry ice cleaning technology, even if the engine is not good, it can be dredged as soon as possible. Dry ice cleaning engines has become a new technology in the 21st century. I. What is dry ice cleaning technology?Dry ice cleaning technology is a new cleaning method that uses the principle of ultra-high-speed jet dry ice particles hitting the surface of objects to achieve cleaning effect. It uses CO2 gas to directly convert liquid carbon dioxide into solid carbon dioxide, which is usually made of particles. The temperature of the ejected carbon dioxide particles is less than -78¢??, which can quickly solidify and fall off the dirt on the surface of the object. This cleaning method does not require the use of any water or organic solvent, so it will not pollute the environment during the cleaning process. It is safe and has a wide range of uses. A piece of dry ice cleaning agent can be applied to the surface of multiple objects. II. Advantages of dry ice cleaning engine 1. Thorough cleaning: The particle size of the dry ice jet is only 0.3 mm, which can smoothly clean all the small holes and corners of the engine, remove all stains and oil stains, so as to thoroughly clean the engine and ensure the delay in engine performance and life.Two. Safety and environmental protection: Unlike other cleaning methods, dry ice cleaning engines does not require any chemicals or organic solvents, which is harmless to the environment and human body, so it is very safe to use. It effectively avoids the risk of damage or short circuit inside the engine by the washing liquid. 3. Convenient and fast: Dry ice cleaning the engine does not require disassembly of the engine. It can be cleaned without disassembly. And the cleaning speed is fast, and it only takes about an hour to complete the complete cleaning of the engine. Four. Economical; the cost of dry ice cleaning the engine is relatively low, and there is no need to spend a lot of manpower and material resources to provide guarantee for the cleaning of the engine. At the same time, using dry ice cleaning machines does not require a lot of time and money to purchase or maintain cleaning equipment. III. Issues to pay attention to 1.Choose a professional service provider: It is recommended to choose a professional dry ice cleaning service provider, because the operation technology of dry ice cleaning machine is relatively complex, and you should not operate it by yourself without training to avoid accidents. Two. Moderate cleaning: Do not blindly pursue cleanliness during the cleaning process, and pay attention to moderate cleaning. There is a certain amount of oil pollution inside the engine shell and inside to protect the internal parts of the car engine from oxidation by oxidizing substances. 3. Repair in time when faults are found: Dry ice cleaning can crush a lot of small amounts of engine impurities. For some visible problems, it is recommended to troubleshoot and repair them in time, and maintain good usage habits to make the cleaning effect more prominent. Dry ice engine cleaning technology is an efficient, safe and environmentally friendly way of automobile maintenance and cleaning, especially in problems such as engine failure and serious exhaust emissions, which has a very good effect.With the gradual popularization and improvement of dry ice cleaning technology, we believe that the technology and standards in this field will become more strict and mature. In addition, there are many new cleaning technologies, which will provide more capture opportunities for the automotive industry and create a better future for modern cars.
