Screen printed glass Lead Glass back tinted on the sides
The screen printing process of glass is based on the screen printing principle. The ink is printed on the surface of the glass, and then the ink is solidified. The printed pattern is firm and durable.
The process flow is as follows: stretching the screen → sizing → drying → printing → developing → drying flat glass → cutting → edging → cleaning and drying → printing and sintering.
Lead glass contains a lot of lead oxide in addition to silica, boron oxide and other glass forms. It is used to manufacture optical glass, electric vacuum glass, low temperature sealing glass, radiation proof glass, lead crystal glass, flint optical glass, low melting glass, delay line glass, high refraction micro bead glass and art ware glass, etc. Function of lead glass: the main performance of lead glass is optically clear and transparent protective shielding. A low optical quality protective glass plate with prescribed attenuation performance is used, and its attenuation performance is 0.22mmpb per millimeter; applicable scope It can be installed in the observation window laboratory of X-ray detection and CT scanning. The lens of the protective window goggles. The X-ray screen of the airport security inspection and the protective window for industrial flaw detection. In radiology medicine, it is often used for radiation protection and shielding, or Observation window for the lead room for filming. According to the different lead content, lead glass mainly has four series: ZF2, ZF3, ZF6, and ZF7. Currently, ZF2 series lead glass is generally used. The high lead glass of ZF6 and ZF7 series has high lead content and the same thickness. The amount of protection is high and the weight is large. ZF series high-lead glass products adopt advanced production technology and optical detection methods. The materials are made of high-lead content optical glass. They have the characteristics of clean internal materials, good transparency, large lead equivalent, and strong anti-radiation ability. , It can effectively block X-rays, gamma rays, cobalt 60 rays and isotope scanning. ZF2, ZF3 series of high-lead glass is widely used in X-ray diagnosis and spiral CT scanning room observation window, medical diagnostic shielding; ZF6, ZF7 series of high-lead glass is mainly used in nuclear power plants, nuclear energy applications and other nuclear industries.
Kindly Note: The radiation-proof lead glass is a kind of brittle materials. Having the heavy specific gravity, it should be taken carefully during the course of movement. When the lead glass Is fixed to the window, the surroundings of the window should be sealed up by lead boards or by lead rubber to prevent the ray's leaking from there. When fixing the radlatlon-proof lead glass, the damp timbers should not be used for the window frames. Because wtien the timbers shrink, the lead glass would be damaged. The surface of the radlation*proof lead glass should not touch or rub with the hard or rough objects to prevent the marks emergence. The radiation-proof lead glass should be used and stored In the dry and ventilation areas. It should not be washed and cleaned by water, or else there will appear some speckle. If It has already appeared some speckle, we can use absorbed cotton with ethanol to wipe it. Because the glass has weak stability, we should keep It away from these chemicals, such as paint, thinner. If they contact each other, the glass can easily be oxidized. In the short time, we can use the ethanol to dean it.
