              防護門鉛玻璃的怎么安裝才能達成效果?
              來源:http://www.mtffz.com 發布時間:2021-01-26

              鉛玻璃里面含有鉛,能夠有效的防止輻射,所以多應用在醫院等輻射較多的地方。鉛玻璃雖然是含有氧化鉛,但是其外表看起來是透明的。只是稍微發黃色,但是并不明顯。防護玻璃一般指防X射線或γ射線或防中子的玻璃。由于物質對放射性輻射的吸收能力隨其含有的金屬元素的原子序數的增大而提高,所以防護玻璃都含有較多量的重金屬氧化物。例如防X射線玻璃含較多量的PbO、BaO等,防γ射線的玻璃含較多量的PbO、WO3、Bi2O3等。由于γ射線的穿透能力較X射線強得多,所以γ射線防護玻璃的比重和鉛當量較X射線防護玻璃高得多。
              Lead glass contains lead, which can effectively prevent radiation, so it is widely used in hospitals and other places with more radiation. Although lead glass contains lead oxide, its appearance is transparent. It's just a little yellow, but it's not obvious. Protective glass generally refers to X-ray or gamma ray or neutron proof glass. As the absorption capacity of materials to radioactive radiation increases with the increase of the atomic number of metal elements, the protective glass contains more heavy metal oxides. For example, X-ray resistant glass contains more PbO, Bao, etc., and gamma ray resistant glass contains more PbO, WO3, Bi2O3, etc. Because the penetrating ability of gamma ray is much stronger than that of X ray, the specific gravity and lead equivalent of gamma ray protective glass are much higher than that of X ray protective glass.
              和普通玻璃相差不大。對于醫院放射科的觀察窗來說,用的是我們的ZF3型號鉛玻璃,其每毫米含鉛量為0.22,但是對于核電站的ZF6或者ZF7來說,由于含鉛量高,其顏色也是黃色比較深。
              It's similar to ordinary glass. For the observation window of the radiology department of the hospital, our zf3 lead glass is used, and its lead content per millimeter is 0.22. However, for ZF6 or ZF7 of the nuclear power plant, due to its high lead content, its color is also dark yellow.

              鉛玻璃的主要性能在光學上是清楚的、透明的防護屏蔽而使用的一種具有規定衰減性能的低光學質量的防護玻璃板,其衰減性能每一毫米為0.22mmpb。醫用鉛玻璃表面涂敷涂料當時,絕關于來說把金屬表和條件隔開了,這種維護效果可稱為屏障效果。
              The main performance of lead glass is clear and transparent protection shield optically. A kind of low optical quality protection glass plate with specified attenuation performance is used, and its attenuation performance is 0.22mmpb per millimeter. When the coating was applied on the surface of medical lead glass, the metal surface was separated from the condition. This kind of maintenance effect can be called barrier effect.
              一般玻璃受γ射線輻照后,玻璃著色,透光度顯著下降。著色程度跟玻璃的組成和結構有關,也跟輻照劑量有關。玻璃的這種特性,叫做輻照穩定性。高鉛玻璃的輻照穩定性較差,輻照著色效應比較明顯。但輻照停止后,放置一段時間,顏色可以逐漸消退。如將玻璃加熱處理,則褪色作用進行很快,玻璃仍可重復使用。另外,為了提高玻璃的輻照穩定性,可以在玻璃中引入少量CeO2,這樣的玻璃受輻照后,透光度下降較小。
              After the general glass is irradiated by gamma ray, the glass is colored and the light transmittance decreases significantly. The degree of coloring is related to the composition and structure of the glass, and also to the radiation dose. This property of glass is called irradiation stability. The irradiation stability of high lead glass is poor, and the irradiation coloring effect is obvious. But after the irradiation stopped, the color could fade gradually after a period of time. If the glass is heated, the fading effect will be fast and the glass can be reused. In addition, in order to improve the irradiation stability of the glass, a small amount of CeO2 can be introduced into the glass. After irradiation, the transmittance of the glass decreases slightly.
