Agent, inorganic type light diffusing agent are a solid microbeads balls from microcosmic angle, and light can not penetrate this solid sphere, can influence
The transmission of many light, only some light pass through through refraction, therefore influence brightness or light transmission.Do fluorescent tube lampshade requirement light transmission
Inorganic light diffusing agent cannot be all selected on rate 50%；Organic light diffusing agent mainly has acryl type, styrene type, acrylic acid
Resin type etc., these resins are transparent or semitransparent in itself, and light can largely pass through, using these light diffusing agents in itself
The difference of the refractive index of material and the refractive index of base material, light repeatedly after refraction, become bright soft by the light of base material, and
It is smaller on the light transmittance influence of material, it is to do the optical materials such as fluorescent tube lampshade to select well.
CN104059246 discloses a kind of inorganic light diffusing agent of light transmission, it is characterized in that：The each component weight percent of composition
For：Ice crystal 85-94%, pyrophillite 3-8%, kaolin 2-5%, potassium feldspar 0.5-1%, shepardite 0.2-1% utilize fluidisation
Bed cladding ice crystal, by mixing granular material with the hot-air heated in circulation flow dynamic furnace, specific surface reaches moment
Igneous fusion, spheroidization coat one layer of reflective layer on ice crystal surface, so as to which ice crystal be made to have good translucency and reflective
Property.
