Quality of metal spraying process on a door to a door means a good powder coating process is inseparable from the door polyurea spray process, of course, inseparable door hardware accessories spray, do not be fooled them, they effect is large. Door hardware accessories prime means what it first contains five pieces:? Locks, hinges, seals, door handles and move the rail. Mobile slide only applied on sliding doors. In selecting the door's first look at locks, hinges and seals in three parts. Lock: Lock There NRK door, folding door (including stainless steel and iron two), as well as raw materials made of galvanized lock this door with screws, convenient device. The current prevailing market contrast material is stainless steel folding door, its delicate appearance process in full compliance bedroom door noble quality, is not only home to ensure the safety of Teflon spray processing plants, and even more perfect to decorate the living space . Hinge: Demand has high strength, high load-bearing capacity, removable convenience, opening and closing sensitivity, noise, and other characteristics of the trigeminal hinge is appropriate. Seal: Since the doors and door panels of contact between head-plate, closing the instantaneous noise up to 120 db or so, seriously affected the physical and mental health?. High strength sealed, not with paint repercussions to ensure smoothness of touch paint. And it has shock absorption, silencers, sealing, noise, moisture, and other characteristics. Cold Spray is a hard-edged solid skills. This approach will be accelerated solid particles ultrasonic kinetic energy into thermal energy upon impact to the outer plating, and then the end of the welding metallurgy. The principle of this skill is: each metal has a specific, temperature-dependent critical particle velocity, when the particle motion will exceed the rate that is welded to the top of the plating. In conventional thermal spraying skills, due to higher temperatures, coating and plating information it will be oxidized to produce metallurgical deformation and the remaining tensile stress. Conversely, the cold spray coating made of skills, the porosity is low (<0.5%), and oxidation, anti-phase transformation, a variety of metals, cermets or combinations of other materials can reduce the tensile stress. In the high-pressure cold spray skills, high pressure helium or nitrogen (350 to 450 pounds / square inch) as a carrier gas, spray data can accelerate to supersonic speeds. The gas is heated and forced through a gathering - divergent nozzle (deLaval), where it is accelerated to supersonic speeds (greater than 1000 m / sec). Spraying particles are written in the upstream side of the nozzle in the axial direction.
