Abstract
A bulb of fluorescent inspection lamp used for non-destructive inspection is made of such components as NiO, BaO, MgO, SiO2, CaO, K2O, Na2O, CoO and B2O3 through proportional mixing and the thickness of its glass bulb is 0.7-0.9 mm. It features high temp. resistance, not liable to cracking at high temp., and full penetration of 3650 nanometers wave.
Description
The present invention relates to the fluorescent inspection lamp used in a kind of nondestructive testing, what be specifically related to is the making of this lamp bulb glass cell-shell.
The fluorescent inspection lamp is a kind of 3650 millimicrons of single medium wave ultraviolet source lamps, is mainly used in industries such as metallurgy, machinery, aviation and does surperficial nondestructive testing, also can be used for textile industry and makes fiber detection usefulness.The gordian technique of fluorescent inspection lamp product is on the bulb glass cell-shell, it is configured to adorn in the black light glass shell pipe in one piece of 125 watts of high voltage mercury lamp, require its glass shell must be all through 3650 mm-waves and all absorb visible light (because visible light disturbs fluorescent inspection), therefore, cause the Lamp bulb case temperature too high easily, cell-shell glass bursts easily, is to detect one technical barrier that industry need solve at present.
The purpose of this invention is to provide a kind of high temperature resistant and bulb case of fluorescent flaw detection lamp of being difficult for bursting.
The present invention is made up of following composition: NiO:9.5～10.5%; BaO:8.7～9.3%; MgO:2.3～2.8%; SiO
2: 58～59.2%; CaO:2.7～3.3%; K
2O:9.6～10.3%; Na
2O:5.7～6.3%; CoO:0.3～0.7%; B
2O
3: 1.5～3.0%.
The technology of the present invention effect:
1, the white light intensity of fluorescent inspection lamp is lower than 20 Luxs under interior 125 watts of-133.75 watts of prerequisites of tube power of assurance high voltage mercury lamp.
2, guarantee in the high voltage mercury lamp under 125 watts of-133.75 watts of prerequisites of tube power 3650 millimicrons of medium wave UV intensity of fluorescent inspection lamp apart from 380 millimeters places greater than 2000 microwatts.
3, above-mentioned white light intensity and 3650 UV intensity indexs are the light intensity index to fluorescence Dynamic Non-Destruction Measurement mensuration of space flight and aviation Department of Industry regulation.
4, can be high temperature resistant and be difficult for bursting.
Bulb case of fluorescent flaw detection lamp must absorb visible light and all need add a large amount of nickel oxide through ultraviolet B radiation in the glass composition, but can cause that the glass envelope shell melting makes the type difficulty and increase, therefore oxide content is the gordian technique of glass cell-shell to select the matrix of glass to add and subtract wherein, and its prescription composition directly influences the quality of cell-shell glass.The applicant once did test of many times and finds: nickel oxide, cobalt oxide can see through ultraviolet ray, absorb visible light, but the too many glass of deal is easy-formation not, and its ratio will guarantee that also the linear expansivity of glass makes it be difficult for bursting with the high voltage mercury lamp sealing-in time, to guarantee becoming vacuum in the cell-shell; Secondly must select the suitable silicon-dioxide and the ratio of boron oxide.General hard material glass (boron glass) silicon content height contains silicon-dioxide 72%～74%, and boron oxide is 16%, is difficult for and the fluorescent lamp bulb coupling, and can not becomes vitreum after adding nickel oxide and cobalt oxide.Therefore, the ratio of the two must make the matched seal of glass ware forming energy, and also high temperature resistant.And glass basis adopts barium matrix (barium carbonate), has both adapted to high temperature, is suitable for the coupling of glass and founding of glass again.
The applicant is through repetition test, by suitable reduction silicon-dioxide and boron oxide content, makes matrix with barium glass then and adds a certain proportion of other composition again and just can realize the present invention.
