Powder is usually the outer surface competence exertion fluorescence in article, and is then difficult to play its effect among matrix.
In this manual, under centrifugal force, the pore of Jing spinning heads throws away spinning liquid, and now spinning liquid temp is higher,
Main body is still liquid, now under industrial nitrogen auxiliary, fluorescent powder is directly attached to into spinning liquid outer layer, by spinning liquid temp
Impact, the fusing of fluorescent material part simultaneously in the dispersion of spinning liquid outer layer, meanwhile, industrial nitrogen has the effect of cooling to spinning liquid,
Spinning liquid solidifies rapidly, also achieve set of the fluorescent powder on refractory fibre surface, is firmly combined with and densification so as to be formed
Fluorescence coating, this is a most important inventive point in this specification.Jing test fluorescent powders are uniform in refractory fibre surface distributed,
The concentration and air velocity of fluorescent powder in industrial nitrogen, gas are then depended primarily on as the thickness of fluorescence refractory fibre fluorescence coating
The concentration of fluorescent powder is higher in stream, air velocity is more low, can obtain the thicker refractory fibre of fluorescence coating.
