摘要
介绍了封孔在铝材氧化着色过程中的必要性及封孔机理，讨论了镍－氟体系常温封孔剂各组分对封孔的作用及常温封孔工艺中诸因素对封孔效果的影响．所研制的封孔剂ＧＹＳ－３由于含有合适的综合抑制剂、平衡复合剂及ｐＨ缓冲剂等助剂，提高了封孔质量，延长了封孔槽液的老化时间，是一种性能优良的常温封孔剂．最佳常温封孔工艺条件为Ｎｉ２＋含量０．８～１．０ｇ／Ｌ，Ｆ－含量０．６～０．８ｇ／Ｌ，ｐＨ值６．０～６．５，封孔温度２０～３０℃，当膜厚为１２μｍ时。
The necessity of hole sealing in the
oxidizing and coloring process for Al profiles are stated. The effect of components in the Ni\|F
system normal temperature sealing agent on the hole sealing and the influence of factors in the
normal temperature hole sealing process on the effect of hole sealing are discussed. Since our
sealing agent GYS\|3 contains suitable aids like comprehensive depressors, balancing
composite agents, pH buffers, etc., the quality of hole\|sealing can be improved and the aging
time of the sealing solution can be prolonged. It is a good normal temperature sealing agent.
The best technical conditions at normal temperature are as follows: when the film thickness is
12m,Ni\+\{2+\} content is 0\^8￣1\^0g/L, F\+- content 0\^6￣0\^8g/L, pH value 6\^0￣6\^5, the
sealing temperature 20￣30 and the sealing time is 10￣12min.
