1. The high temperature resistant flexible air duct has excellent thermal insulation performance and is used for constant temperature gas insulation transportation.
What is a high temperature resistant flexible air duct?
High temperature resistant flexible air duct is also known as flame retardant fireproof insulation flexible air duct, central air conditioning insulation flexible air duct, high temperature heat insulation flexible air duct, constant temperature gas transmission flexible air duct, etc. The high temperature resistant flexible air duct is made of high temperature vulcanized silicone tube, and the flexible air duct is wrapped in white. Light yellow or pink, 2.5cm thick glass wool. During the production process, the insulation glass wool will be pressed and wrapped around the flexible air duct. Usually, after wrapping glass wool, the thickness of the finished pipe fittings shall not exceed 1cm, and a layer of high-temperature-resistant aluminum foil is added to the insulation glass wool.
The high temperature resistant flexible air duct is to add a layer of insulation cotton on the basis of the ordinary heat resistant flexible air duct to play the role of heat preservation. There is a misunderstanding here, many people will think that insulation is to isolate the heat in the flexible air duct from the outside world, and the outside temperature cannot be reached. This is a wrong idea. Insulated flexible air ducts only hold heat for a certain period of time. If the internal temperature of the insulation flexible air duct can withstand a high temperature of 350°C for a long time, there will be no external temperature when the hot air starts. After a while, the outside of the insulated flexible air duct will feel a little hot to the touch. After about seven or eight hours, the insulated flexible air duct will reach the same temperature as the inside of the flexible air duct. Therefore, the insulated flexible air duct actually only slows down the temperature radiation inside the flexible air duct, and cannot always maintain the insulation.
Application of high temperature resistant flexible air duct: hot and cold air insulation guide, hot soft circulation insulation, plastic industrial particle drying, dust removal and exhaust device, heater insulation exhaust, blast furnace exhaust and welding gas exhaust, exhaust equipment, engine structure and heating engine , aircraft equipment and military equipment.
2. High temperature resistant insulation flexible air duct is a flexible air duct made of glass fiber cloth coated with silicone rubber.
Silicone-coated glass fiber cloth is made of glass fiber cloth as the base material, evenly coated or calendered with silicone rubber. It is an excellent silicone rubber compound with high density and is evenly dispersed on glass fiber cloth. Silicone cloth has good air tightness and can well block the erosion of chemical solvents such as water and steam. At the same time, the excellent tear strength can prevent sharp objects from scratching or piercing the surface, effectively protecting the fluid in the tube.
This high temperature resistant flexible air duct produced from silicone rubber coated fiberglass fabric is mainly reinforced by helical steel wire. The pressure that the flexible air duct can withstand mainly depends on the thickness and winding density of the steel wire. The thicker the steel wire, the greater the pressure resistance; the larger the spacing of the steel wire threads, the smaller the pressure resistance of the flexible air duct, and the smaller the spacing, the greater the pressure resistance.
Flame retardant conforms to DIN4102-B1, American UL94-VO, wear resistance, strong alkali and strong acid resistance, stable chemical properties; and the bending radius is about 4 times the outer diameter, good flexibility, anti-condensation dew condensation, heat insulation, excellent flame retardant and fire proof performance.
