影响磷化效果的因素-表调：
质量鉴定：当静止的时候，表调剂呈乳白色，而且能长时间保证颜色不变，没有沉淀的为好（乳白色时间越长，效果越好）。如果太清澈还容易沉淀，那就是质量差的表调。
根据通过表调剂力的光线来判别表调分子大小，好的表调剂的透光性能很好，有点发黄，这表示表调剂离子小于或等于波长，表明活性高，效果好，反之，差的表调剂的离子较大，溶液比较浑浊，通光性能弱，只能通光强光。
磷化膜性能。通过磷化效果来测试磷化膜速度的快慢。将工件浸入磷化液里磷化5分钟后。如果表调质量好，磷化速度快，而且磷化均匀细密。如果差的表调，磷化膜比较粗糙。还能在温度非常低的时候试验，更严格控制表调的质量。
测试钛离子的含量，配比颜色准确的表调剂，分别配浓度不等的表调剂，各取表调剂300ml在比色管中，并加入浓硫酸，摇均匀后加双氧水10ml，再摇匀即可显示各标准液颜色。
比色，以标准的表调液颜色和工作液颜色对比。能确定表调液的浓度。
防锈油
防锈油是影响磷化防锈性能的关键，我公司自主研发的乳化自干油。
使用方法：配比5％-5.5％，搅拌均匀，加温到70°±5°，保持此温度。测试工作液中的PH值8-10，8.5*佳。
浸油过程中的工作液不断搅拌（使用泵或搅拌机），使温度达到要求后，将处理的产品放入槽中4-5分钟。将产品从乳化油中拿出，将水虑干之后用风管吹干或烘干。
乳化油使用寿命：适气候环境与生产频率而定。
出现以下情况时应更换槽液：
1. 槽液出现浅黄（棕）色
2. 槽液静止时，表面出现很多浮油，甚至来回浮动。这表明浓度较低。
3. 加工件末端有油点现象
4. 严重时加工件在干燥处理后，也完全有油点。
浸油之前的工件表面要求：
1. 工件表面的污垢需清楚干净，需做到三次以上的串联清洗。
2. 工件表面上不可有酸性残余，表面PH值为中性。
3. 盐分过多PH值下降，盐分沉淀于槽液中，从而破坏磷化水中的油分，造成棕色或破坏乳化剂
要经常测试槽液的水温，PH值每天测量调整，经常检查槽液的油量。高温锰系磷化液
Qualification: when resting, table regulating is ivory, and can guarantee the same color for a long time, no precipitation for good (ivory time to grow more, the better the results). If you are too clear also easy to precipitation, that is poor quality table adjustment. According to the table regulating force light to discriminant table adjustable molecular size, good table regulating the pervious to light performance is very good, a little yellow, this means that table regulating ion less than or equal to wavelength, show that high activity and good effect, on the other hand, poor table regulating ion is bigger, solution is turbidity, through optical performance weak, can pass the light bright light. Phosphating film performance. Through the phosphating effect to test the speed of the speed of the phosphating film. The workpiece dip phosphating solution in phosphate in five minutes. If table adjustment are of good quality and phosphating speed, and phosphating even close. If poor table to move, phosphating film is rough. In a time of very low temperature test, more strictly control the quality of the adjustable table. Test titanium ion content, the matching color accurate table regulating, respectively with concentration unequal table regulating, each take table regulating 300 ml in the color tube, and add concentrated sulfuric acid and hydrogen peroxide, shake well after 10 ml, then shake can show the standard liquid color. Color, a standard table adjustable liquid color and working fluid color contrast. Can determine the concentration of liquid adjustable table. Rust-preventative oil Anti-rust oil is the key influence phosphating antirust performance, my company independent research and development of the emulsion from dry oil. Method of use: ratio of 5% - 5.5%, stir well, heating to 70 ° ± 5 °, keep the temperature. Test the working liquid PH eight to ten,8.5 best. In the process of oil liquid constantly stirring (using pump or blender), make temperature requirements, will be processing products into the groove of 4 to 5 minutes. The product from the emulsified oil out of the water after the dry with wind blow dry or drying. Emulsified oil service life: comfortable climate environment and production frequency and decide. |
