With the continuous improvement of scientific and technological development in my country, the proportion of public facilities in buildings has increased, and the external equipment has increased, so the safety standards of important pipelines in buildings have also increased, and the requirements of pipeline antifreeze systems have also increased. Due to the relatively low ambient temperature in winter in the north, various liquid conveying pipes are frozen and blocked to varying degrees, and even burst, which has a serious impact on people's work and life. The fire pipeline is the last line of defense to ensure the safety of the building. Once a fire occurs after the fire pipeline freezes in winter, the fire pipeline will not be able to be used in time, posing a great threat to the safety of the entire building. Therefore, fire pipelines are closely related to people's lives, and their significance is even more significant. As an effective antifreeze solution for fire pipelines, electric heating cables are widely used in fire protection pipelines, fire hydrants and other fire engineering facilities in major cities, effectively ensuring the safety of residents' lives.
El principi de funcionament del cable de traçat de calor elèctric autolimitant és compensar la pèrdua de calor de la canonada de traçat de calor mitjançant l'intercanvi de calor indirecte o directe a través de la calor emesa pel cable de traçat de calor elèctric, per tal de complir els requisits d'anti-congelació i conservació de la calor, i garantir l'ús normal de la canonada d'incendis al fred hivern. El sistema de rastreig de calor elèctric té els avantatges d'un bon rendiment de memòria, un petit corrent d'arrencada, una baixa taxa de decadència anual i una llarga vida útil. l'objectiu de.
El seguiment elèctric de la calor requereix diferents materials en diferents condicions d'ús, i les seves funcions també són diferents. Per exemple, si el material d'aïllament impermeable de traçat de calor elèctric no està protegit pel material d'aïllament impermeable al mateix temps que s'instal·la el cable de traçat de calor elèctric, el traçat de calor elèctric pot provocar un curtcircuit quan entra en contacte amb la font d'aigua. . Al mateix temps, com que l'aigua és freda, també augmentarà la càrrega de treball del rastreig de calor elèctric, provocarà malbaratament de materials i afectarà la vida útil del rastreig de calor elèctric.
Electric heating cables are used more and more in our daily life, and thermal insulation materials are also an important factor for electric heating to maintain the heating effect. It may be difficult to meet the requirements, which shows the important role that electric heat tracing waterproof insulation materials play in the whole electric heat tracing system. Many people are very confused about electric heat tracing waterproof and thermal insulation materials, and do not know what kind of material to choose. It is recommended to use polyurethane rigid foam waterproof thermal insulation material.
