    Waterproof technology review

         Brushless fan have to working in severe envirment some times.Such as high humidity,high corrosion resistance envirment.Tkfan improve fan's waterproof performance continually.Our plastic cover motor can be used for these special project now. This kinds of plastic material called epoxy resin.It's same as the material used for integrated circuit package.For thes motor which have high speed, high power performance, we also adopt the thermal conductivity is higher thermal conductive silicone seal.We usually think of waterproof fan divided into IP55 and IP68 waterproof grade, IP55 waterproofing of waterproof fan or motor only has moistureproof function.Manufacturing methods commonly used in motor outer surface, anti-corrosion paint with antioxidant ability.
    IP68 waterproof fan at present generally adopts vacuum coating or encapsulation mode.Vacuum coating process is to use similar to semiconductor lithography technology, used in vacuum vapor deposition way of deposits a layer of nanometer materials on surfaces.Film thickness is usually 5 ~ 30 microns.Coating process has advantages of good heat dissipation effect, fast batch manufacturing.But generally not corrosion nanomaterials, film will fall over time, the highest can be used in steam environment.After the epoxy resin sealing waterproofing fan can be corrosion resistant, water can shock, but the slow speed of manufacturing, motor cooling effect is not good, the price is generally more expensive.
