Abstract
1. Устройство для нанесения покрытий из полимерных порошковых композиций электрогазопламенным способом, содержащее рукоятку со смонтированным на ней зарядным элементом, ствол с центральным каналом внутри для потока распыляемой порошковой композиции, узел нагрева потока воздуха, отличающийся тем, что центральный канал внутри ствола выполнен в виде керамической трубки с антифрикционным покрытием внутри, узел нагрева потока воздуха включает корпус с расширяющимся входным и сужающимся выходным участками, на выходе которою имеется распыливающий насадок, внутри корпуса установлен тороидальный коллектор с рядом отверстий, оси которых направлены вдоль потока для равномерного распределения воздуха вдоль центральной трубки, за тороидальным коллектором установлены, по меньшей мере, два ряда проволочных нагревателей, расположенных взаимоперпендикулярно относительно оси корпуса, на распыливающем насадке установлен инфракрасный излучатель, содержащий съемный корпус, коаксиально расположенный относительно его внешней стенки, с образованием кольцевой полости, закрытой со стороны движения потока и открытой со стороны выхода потока, сообщенной с источником газа, внутри кольцевой полости установлено керамическое кольцо с рядом отверстий малого диаметра для обеспечения беспламенного горения газовой смеси.2. Устройство по п. 1, отличающееся тем, что по внутреннему диаметру распыливающего насадка выполнены наклонные винтообразные канавки для обеспечения вращательного движения потока горячего воздуха.3. Устройство по п. 2, отличающееся тем, что наклонные винтообразные канавки расположены под углом 15-18° относительно1. Device for coating polymer powder compositions by an electro-flame method, comprising a handle with a charging element mounted on it, a barrel with a central channel inside for the flow of the sprayed powder composition, an air flow heating unit, characterized in that the central channel inside the barrel is made in the form of a ceramic tubes with an anti-friction coating inside, the air flow heating unit includes a housing with an expanding inlet and tapering outlet sections, at the outlet of which there is a spray There is a toroidal collector inside the casing with a series of holes, the axes of which are directed along the flow for uniform distribution of air along the central tube, at least two rows of wire heaters are installed behind the toroidal collector, mutually perpendicular to the casing axis, an infrared nozzle is installed an emitter comprising a removable housing coaxially located relative to its outer wall, with the formation of an annular cavity, closed with Torons flow and open flow from the outlet communicating with a gas source within the annular cavity of a ceramic ring with a number of small-diameter holes to provide the flameless combustion gas smesi.2. The device according to claim 1, characterized in that inclined helical grooves are made along the inner diameter of the spray nozzle to provide rotational movement of the hot air stream. 3. The device according to claim 2, characterized in that the inclined helical grooves are located at an angle of 15-18 ° relative to
