辽源电影胶片厂与空军天津医院合作,研制成功了低含银量毛面医用X光胶片,该胶片采用右旋糖酐与不饱和单体接枝共聚物高效遮盖力剂和珠状聚甲基丙烯酸甲酯照相毛面剂,平均涂布银量为6.41±0.35克/米~2(双面),感光度50±15,平均斜率2.2±0.4,灰雾小于0.15,最大密度大于3.0。老化试验,性能衰退小。经部队和民间医院临床应用,清晰度和对比度良好,灰雾小,影象层次丰富,保存期间抗粘连性能好,能满足诊断使用要求。在此基础上于1983年11月底在天津召开了鉴定会,通过了鉴定。辽源胶片厂即将投入大批量生产。
Liaoyuan Film Factory and the Air Force Tianjin Hospital, the successful development of a low silver content of the matte medical X-ray film, the film using dextran and unsaturated monomer graft copolymer high efficiency covering agent and beads polymethyl methacrylate The average coated silver content was 6.41 ± 0.35 g / m ~ 2 (double-sided), the sensitivity was 50 ± 15, the average slope was 2.2 ± 0.4, the fog was less than 0.15 and the maximum density was more than 3.0. Aging test, small performance decline. The clinical application of troops and private hospitals, good clarity and contrast, small fog, rich image levels, anti-blocking performance during storage, to meet the diagnostic requirements. On this basis, an appraisal meeting was held in Tianjin at the end of November 1983, which passed the appraisal. Liaoyuan Film Factory is about to put into mass production.
