熱線吸収ガラスに関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a heat-resistant ultraviolet-transmissive heat-absorbing glass made of borosilicate glass that transmits ultraviolet rays with a wavelength of 254 nm and absorbs visible and infrared rays.

な方法が採用されている。Conventionally, ultraviolet curing resins and the like have been cured by irradiating ultraviolet light using a mercury lamp, but the temperature of the object to be irradiated increases due to infrared rays and radiant heat from the light source. For this reason, when curing a resin film or the like that is not heat resistant, the envelope tube of the mercury lamp is formed with a double tube body, and cold water is introduced into the space to remove the radiant heat. However, this water cooling method requires a large and complicated device, so recently, 254nm, which is effective for resin curing, has been installed between the mercury lamp and the irradiated object.
A convenient method has been adopted in which a glass filter that transmits ultraviolet rays well and absorbs heat rays is installed to block infrared rays and radiant heat.

Phosphate glass is used as a glass that transmits ultraviolet rays and absorbs visible and infrared rays, but it has poor weather resistance.
When used for a long period of time, the surface deteriorates and the transmittance of ultraviolet rays decreases dramatically. In addition, a glass filter made of silicate glass that transmits 254 nm ultraviolet rays has low heat resistance, so if the device is miniaturized using a high-pressure mercury lamp, it will be damaged by heat.
