Why heating cables are used in containers

　　In today's globalisation, container transport has become one of the main modes of international trade. Container transport not only improves the efficiency of cargo transport, but also reduces transport costs. However, in the cold environment, the goods inside the container may be damaged due to low temperature. In order to protect the safety of goods, heating tape, as a kind of efficient heating technology, is gradually widely used in container transport.

　　In this paper, we will discuss why the accompanying heat belt is used in the container, aiming at providing scientific and rigorous solution for the temperature control of container transport.

　　First, accompanies the heat the basic principle of the heat tape

　　Accompanied by the tropical is a kind of through the electric current fever cable, its internal contains the conductive polymer composite material and two parallel metal wire. When the current passes, the conductive polymer composite material will produce heat, so as to achieve the effect of heating. The accompanying tropical belt has the function of automatically adjusting the temperature, when the temperature rises, its resistance will increase, so as to reduce the output power; On the contrary, when the temperature decreases, its resistance will decrease, so as to increase the output power.

　　Second, accompanies the tropical belt to use in the container the reason

　　1. Safeguard cargo safety

　　In the container transport process, many goods need to maintain a certain temperature to ensure its quality and safety. The accompanying heat tape can be installed in the container, provides the constant heating, ensures the goods in the transport process the temperature demand. For example, when transporting temperature-sensitive goods such as foodstuffs, medicines, chemicals, etc., heating tape can be used to heat the container, maintain the temperature inside the container, and prevent the goods from deteriorating or being damaged due to low temperature.

　　2. Improve transport efficiency

　　In the cold environment, the goods inside the container may freeze because of the low temperature, leading to the difficulty of unloading and affecting the transport efficiency. The heating tape can be installed inside the container to provide constant heating to prevent the cargo from freezing, ensuring smooth unloading. For example, when transporting high viscosity cargoes such as liquid asphalt, petroleum, animal and vegetable oils, heating cables can be used to heat the container to maintain the temperature inside the container, preventing the cargo from freezing due to low temperatures and improving unloading efficiency.

　　3. Energy cost saving

　　Compared with the traditional heating method, the heating tape has higher energy efficiency. By automatically adjusting the temperature, the heating tape can reduce unnecessary energy consumption, thus saving energy costs. For example, in the process of container transport, the accompanying heat tape can be used to heat the container, keep the temperature inside the container, reduce the heat loss, and improve the heating efficiency; during the container parking period, the accompanying heat tape can be used to keep the temperature inside the container, reduce the heat loss, and improve the heat preservation effect.

　　4. Reduce maintenance cost

　　The accompanying heat tape has longer service life and lower maintenance cost. Compared to traditional heating methods, heating tape does not require frequent replacement and repair, thus reducing maintenance costs. For example, in the process of container transport, the accompanying heat belt can run stably for a long time, reducing the downtime and maintenance cost caused by equipment failure; During the container parking period, the accompanying heat belt can run stably for a long time, reducing the downtime and maintenance cost caused by equipment failure.

　　5. Improve environmental protection level

　　As a kind of clean energy, the accompanying heat belt does not produce harmful gases and pollutants. Compared with the traditional heating method, the accompanying heat belt can effectively reduce the environmental pollution and improve the level of environmental protection. For example, in the process of container transport, accompanied by the heat can replace the fuel oil boiler, reduce the emission of carbon dioxide and particulate matter, improve the air quality; In the container parking period, accompanied by the heat can replace the coal-fired boiler, reduce the emission of sulphur dioxide and nitrogen oxides, improve the air quality.

　　To sum up, as a kind of efficient heating technology, heating tape has the advantages of guaranteeing the safety of goods, improving the transport efficiency, saving energy cost, reducing the maintenance cost and improving the level of environmental protection. Therefore, the application of heating tape in container transport has important practical significance and broad development prospect. In the future, with the progress of science and technology and the development of the logistics industry, the accompanying heat belt will play an increasingly important role in the container transport, for the container transport of high efficiency, safety and environmental protection to provide strong support.
