In the future, full state is full of confidence and hope, was determined in a more high quality brand and good service, sincere cooperation with customers at home and abroad, to do the northern area of the thermal compensation smoke duct equipment industry's first brand.
Non-metallic compensator of the skin
Non-metallic compensator skin, skin with nonmetal fabric non-metallic expansion joint skin, skin fabric expansion section, the desulfurization efficiency, denitration efficiency such as name, mainly composed of multilayer fire protection of high temperature resistant glass fibre fabric and heat preservation cotton, has a wide scope of heat-resistant, high pressure resistance, corrosion resistance ability strong, good flame retardant performance, sound-absorbing noise reduction, isolation vibration, good flexibility, and many other advantages. Can effectively reduce the boiler, fan, long distance pipeline system, such as noise and vibration, can simplify the line of the whole system design. Compared with metal compensator, low price, light weight, quick, replace the advantages of simple and convenient.
The characteristics of the non-metallic compensator skin
Thermal expansion: 1, compensation can compensate the direction, much better than that of unitary compensation only metal compensator.
2, compensation installation error: because in the process of the pipe connection, and the system error, fiber expansion joint skin better compensated the installation error.
3, anechoic anti-vibration: fabrics, heat preservation cotton body itself has the function of sound absorption, vibration insulation transmission can effectively reduce boiler, fan noise and vibration of the system.
4, no reverse thrust: as the main materials for fabrics, unable to pass. With fibre compensator can simplify the design, avoid using large bearings, save a lot of materials and Labour.
5, good high temperature resistance, corrosion resistance, selection of fluorine plastics, organic silicon material has good high temperature resistance and corrosion resistance.
6, sealed performance is good: there is a perfect system of production, assembly, fiber compensator can ensure no leakage.
7, light weight, simple structure, easy installation and maintenance.
Non-metallic compensator skin material selection
Non-metallic compensator skin main effect is the flue gas system under pressure as well as from the flue gas or chemical etching of the outside world, ring surface must be flexible to absorb from the direction of displacement. Outer usually take weatherability good for silica cloth, also can use YiBingBu fluorine tape, PVC cloth and three yuan. According to the temperature of the system to decide whether to do the other thermal insulation layer.
The overlock cloth of non-metallic skin can use glass fiber cloth, silicone cloth, ceramic fiber cloth, fluorine tape in any breed, need according to the working condition and high cost in the actual application to determine what type of package and cloth.
Non-metallic envelope according to the working condition, hot, cold wind non-metallic expansion joint compensator using silicone rubber tape in the skin, skin flue fabric using fluorine rubber adhesive. Nonmetallic skin ring under the environment of high temperature, when using silica gel fire prevention cloth, choose red as the molecular structure of the silicone rubber decided it has high thermal stability, its heat resistance performance is greatly superior to other analysing except fluorine rubber, and the price is moderate, which has been widely used in domestic different fields; So for medium is used in a hot air cooling way of nonmetal skin silicone adhesive is more appropriate.
Power plant flue gas environment contains a lot of such as SO2, SO3, HCl and HF acid, silica gel under the effect of trace amounts of acid performance drops rapidly, even in its internal anti-corrosion layer, also easily lead to leaking in the operation of the slip joint performance drops rapidly, product damage soon, so choose silicone rubber in the flue of nonmetal skin is inappropriate.
Flue non-metallic expansion joint skin with the fluorine adhesive. Fluorine rubber is refers to the main chain or side chain of carbon atoms containing fluorine atoms on a synthetic polymer elastomer, it has a high temperature resistant, oil resistant and characteristics of a variety of chemical erosion resistance. Fluorine rubber can be in long-term work under 200 ℃, is the rubber material in the corrosion resistance of the best rubber materials, power plant flue gas containing almost no corrosion of acid gases for fluorine rubber, fluorine rubber is therefore material of choice for power plant flue gas environment non-metallic skin, although price is a bit expensive, but ensure the quality, appropriate and necessary in the long run.
