氨基磺酸制作清洗剂时怎么才能发挥出效果?
来源:http://www.jnjrh.com 日期:2019-09-30 发布人:admin
1、断开与冷却盘管无关的其它系统,将清洗槽、清洗泵跟冷却盘管联接成一个清洗闭合回路;
1. Disconnect other systems unrelated to the cooling coil, and connect the cleaning tank, the cleaning pump and the cooling coil to form a cleaning closed loop.
2、水冲洗。目的是为了在模仿清洗状态下对清洗系统的走漏状况停止检查,同时肃清盘管内松懈的污物,当出口处冲洗水目测无大颗粒杂质存在时,水冲洗完毕。
2. Rinse with water. The purpose is to stop checking the leakage of the cleaning system under the simulated cleaning condition and remove the loose dirt in the coil. When there is no large particle impurity in the flushing water at the outlet, the water is flushed.
3、酸洗除垢。水冲洗完毕后,在清洗槽内循环添加津南品牌氨基磺酸清洗剂,控制清洗主剂浓度在3-6%,温度在50-60℃的范围内,于系统内停止循环清洗去污,清洗时间2-3小时左右;每隔20分钟用pH试纸丈量一次清洗酸液的pH值,使其维持在1以下,当pH值在1小时内趋于稳定值且清洗系统内没有气体放出时,完毕酸洗过程。
3. Scale removal by acid washing. After rinsing with water, add Jinnan brand aminosulfonic acid cleaning agent in the cleaning tank, control the concentration of main cleaning agent in the range of 3-6%, temperature in the range of 50-60 C, stop circulating cleaning and decontamination in the system, the cleaning time is about 2-3 hours; measure the pH value of acid cleaning solution with pH test paper every 20 minutes to keep it at 1. Under this condition, when the pH value tends to be stable within 1 hour and no gas is released from the cleaning system, the pickling process is completed.

4、清洗工序完成后,停止水冲洗,冲洗残留淤泥及残渣。
4. After the cleaning process is completed, stop water washing and flush residual sludge and residue.
5、水冲洗合格后,循环添加津南牌清洗钝化剂停止钝化处置,来进步管路的耐腐蚀性能,待整个系统溶液浓度混合平均后中止循环,浸泡2~3小时,然后将钝化液扫除系统,清洗过程完毕。
5. After water washing is qualified, the passivator of Jinnan brand is added to the pipeline to stop passivation treatment, so as to improve the corrosion resistance of the pipeline. After the average concentration of the whole system solution is mixed, the cycle is stopped and soaked for 2-3 hours. Then the passivator is swept out of the system and the cleaning process is completed.
6、清洗完毕后,翻开清洗系统,从冷却盘管口察看,管内外表应干净,无残留污垢、无点蚀、无脱锌腐蚀等现象,化学清洗后,管路应没有发作走漏现象,即为合格。
6. After cleaning, turn on the cleaning system. From the inspection of the cooling coil, the inside and outside of the pipe should be clean, without residual dirt, pitting corrosion, dezincification corrosion and other phenomena. After chemical cleaning, the pipeline should not leak, that is qualified.
氨基磺酸清洗剂相关于其它酸洗的优势:
Aminosulfonic acid detergent has advantages related to other pickling:
化学酸性清洗中,用得最多的酸是盐酸和硫酸,但盐酸和硫酸的酸性强,对金属资料的腐蚀性大,同时在清洗过程中产生酸雾,对环境形成污染,清洗后构成大量沉淀物,清洗过程复杂。
In chemical acid cleaning, hydrochloric acid and sulphuric acid are the most used acids, but they have strong acidity and are highly corrosive to metal materials. At the same time, acid fog is generated during the cleaning process, which pollutes the environment. After cleaning, a large number of precipitates are formed, and the cleaning process is complex.
氨基磺酸是一种不吸潮、不熄灭、不爆炸、价廉易得、稳定性好的固体强酸,具有与盐酸、硫酸相同的强酸性,对有机酸的酯化反响具有很好的催化效果,但腐蚀性却小得多,用氨基磺酸清洗金属时不会产生酸雾,清洗后没有固体沉淀物构成,可大大缩短清洗过程;
Aminosulfonic acid is a kind of solid strong acid with no moisture absorption, no extinguishing, no explosion, low price, easy availability and good stability. It has the same strong acidity as hydrochloric acid and sulfuric acid. It has a good catalytic effect on esterification reaction of organic acids, but its corrosiveness is much smaller. When cleaning metals with amino sulfonic acid, there will be no acid fog. The composition of solid sediment can greatly shorten the cleaning process.
氨基磺酸清洗剂是固体,具有储存、运输便当,容易配制、运用平安等很多优点,特别适用远途运用;
Aminosulfonic acid cleaning agent is solid, which has many advantages such as convenient storage, transportation, easy preparation, safe use, etc. It is especially suitable for long-distance use.
