Glass bead for projection screen

Product Characteristic: I.

Film plating glass bead can insulate water very strongly, and solve the problemof the screen drawing the cloth validitively. surface of film plating bead has used the organism material of the high refractive index, so changes the characteristic , and resolves the problem of glass bead sticking the resin not firmly. plating glass bead can produce the certain buoyancy in the process of screen drawing the cloth, and make it evenly arrange in the screen surface, so can increase the screen's bright degree coefficient. plating glass bead has certain ability of cleaning itself, and dies down the screen to attach the dirty in the air , so make the screen not easily polluted. ideal depth that film plating glass bead goes into the screen's surface is 60%, the surface peeps out is 40%, and at this time the bright degree is the best.Product Main Technology Index Specification(mm) Appearance Specific Gravity Roundness LuminanceCoefficient PackingCommonglass bead 0.05-0.090.09-0.120.15-0.25 free of color, transparent,clean, globosity 2.4-2.6g/cm3 >90% ≥2.20 Cardboard Box25kg/boxHigh luminanceglass bead 0.05±10%0.09±10%0.12±10%0.15±10%0.25±10% high luminance globosity, no impurity,grains are uniform 2.5-2.9g/cm3 >95% 2.20-2.60 Iron Bucket25kg/bucket
