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.
Načelo delovanja -samoomejevalnega električnega kabla za sledenje toplote je kompenzirati toplotne izgube toplotnega cevovoda s posredno ali neposredno izmenjavo toplote skozi toploto, ki jo oddaja električni grelni kabel, tako da se izpolnijo zahteve zaščite proti-zmrzovanju in toplote ter zagotovi normalno uporabo požarnega cevovoda v mrzli zimi. Sistem za sledenje električnega ogrevanja ima prednosti dobre zmogljivosti pomnilnika, majhnega zagonskega toka, nizke letne stopnje razpadanja in dolge življenjske dobe. cilj.
Električno sledenje ogrevanja zahteva različne materiale v različnih pogojih uporabe, njegove funkcije pa so tudi različne. Na primer, če vodoodporni izolacijski material za sledenje električnega ogrevanja ni zaščiten z vodoodpornim izolacijskim materialom hkrati, ko je nameščen električni grelni kabel, lahko električni grelni sledilnik povzroči kratek stik, ko pride v stik z vodnim virom. . Ker je voda hladna, bo hkrati povečala obremenitev električnega sledenja toplote, povzročila odpadke materialov in vplivala na življenjsko dobo električnega sledenja toplote.
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.
