The difference between the environmental protection thermocouple and low smoke zero halogen thermocouple

In many parts of key projects, such as the place like the fire control, monitoring, alarm can use low smoke zero halogen thermocouple wire, thermocouple people usually call it environmental protection, environmental protection thermocouple is not actually refers to the low smoke zero halogen thermocouple, the following is the difference between the thermocouple and low smoke zero halogen thermocouple in detail: 1, no halogen: adopt green environmental protection insulation, sheath and special material, oxygen insulation layer not only has excellent electric properties, physical and mechanical properties, and ensure that the product does not contain halogen, solved the forms when the combustion & quot; Secondary pollution & quot; To avoid the traditional that can cause cancer when burned, PVC & quot; Dioxin & quot; Material. 2, high flame retardancy: environmental thermocouple completely ensure that requirements for high building fire-fighting requirements, fire when the thermocouple is not easy to burn, and can prevent the spread of the combustion flame after expanding and disaster. 3, low toxin: in the insulation and sheath does not contain harmful heavy metals such as lead, cadmium, when thermocouple used and waste disposal will not produce pollution to soil and water. And after a rigorous toxicity experiment, the mice under the experimental conditions stipulated by the safe. 4, do not produce corrosion gas: adopt to the environment pollution-free new special coating material, the production, use process and the combustion will not produce the gas, such as HCL acid gas emissions is few, small damage to personnel and equipment, instruments, more environmental protection characteristics. 5, waterproof, uv protection: the use of special molecular structure of green environmental protection material, low water absorption. Special uv absorber, make the products with good uv protection function. Make sure the safety of the product use and prolonging the service life. The first to launch & quot; Environmental protection thermocouple & quot; Name is a Japanese company, its product standards set by the FN ( Ecomaterial) Ecological thermocouple standard, Britain in the western countries also developed advanced thermocouple standards of environmental protection, has since spread to all over the world. 6, high light transmittance: thermocouple smoke when burning is very thin, and is advantageous to the personnel evacuation and fire fighting work. Product light transmittance is greater than 40%, far higher than the traditional flame retardant type thermocouple light transmittance is less than 20% of the standard.
