95%Al_2O_3瓷活化钼锰法金属化封接工艺,虽然比较成熟,可是还不太稳定,有些工艺条件还不够严格,有时还会出现漏气、脱焊、不粘瓷、强度低(500公斤/厘米~2)等质量问题。正交实验法为我们确定最佳工艺提供了捷径。基本模清了95%Al_2O_3瓷活化钼锰法9~#配方金属化封接工艺的规律。试验结果如下:一、关键因素——膏剂比例本试验发现了膏剂比例是个关键性的因素。如果追求便于涂复而少加硝棉溶液,多加醋酸丁酯稀释,则将把封接强度降低200～300公斤/厘米~2。膏剂比例以粉:硝棉溶液:醋酸丁酯=4:1:0.15强度最高。
95% Al_2O_3 ceramic activated molybdenum manganese metal sealing process, although more mature, but not yet stable, and some process conditions are not strict enough, and sometimes leakage, desoldering, non-stick porcelain, low strength (500 kg / Cm ~ 2) and other quality problems. Orthogonal experiments provide us a quick way to determine the best process. The rule of 95% Al_2O_3 ceramic activation molybdenum and manganese method 9 ~ # formula metallization sealing process was basically modeled. The test results are as follows: First, the key factor - the proportion of paste This test found that the proportion of paste is a key factor. If the pursuit of easy coating and less with a solution of cotton, add more butyl acetate dilution, will reduce the sealing strength of 200 to 300 kg / cm ~ 2. Paste ratio to powder: cotton solution: butyl acetate = 4: 1: 0.15 the highest intensity.
