一、X 光胶片处理法将胶片全部浸泡在15～20%工业烧碱或4N～6N 氢氧化钠或4N—6N 硝酸溶液中。20分钟左右(根据 X 光片的曝光的具体情况,浸泡时间可长可短)。待胶片上的药膜层自行脱落时,取出胶片,自来水中洗净,挂起使其自然凉干。即得光滑明亮的拷贝片基。(编者按:一种更经济更简便的方法是:将 X 光胶片放入滚烫的浓石灰水里3～5分钟,即可得到脱药膜的透明胶片。)二、用复印机复制拷贝的方法1.修剪掉片基顶端两侧不平整且有图钉孔眼处,否则输入复印机过程中可造成故障。2.根据需要将片基加工成16～32开大小备用。3.取52～80克/m~2的复印机纸作片基
First, the X-ray film processing method All films soaked in 15 ~ 20% industrial caustic soda or 4N ~ 6N sodium hydroxide or 4N-6N nitric acid solution. About 20 minutes (according to the X-ray exposure of the specific circumstances, soaking time can be long or short). When the drug film layer on the film falls off on its own, the film is taken out and washed in running water to suspend it to dry naturally. That is smooth and bright copy film base. (Editor’s note: A more economical and easier method is to place the X-ray film in boiling hot lime water for 3 to 5 minutes to get a clear film of the release film.) Second, copy the copy with a copier 1. Trim off the top of the film on both sides of the top notched and thumbtack holes, or enter the copier process can cause failure. 2. According to the need to base processing into 16 ~ 32 open size spare. Take 52 ~ 80 g / m ~ 2 copier paper base
