4、理槽：Rust removing and oil clea ning tank:按體積比：BR-101A : CA-66 :水=1:6:3配制工作液。當大氣氣壓 低或者天氣有霧時，按1%向槽內加入BN- 111酸霧抑制劑，用來控 制槽液酸霧揮發(fā)。As the ratio by volume to make the working solution .When the atmos is low or there is any fog , add 1% Acid fog inhibitor BN-111 by volume .(2) 中和處理槽：Neutralizer Tank : 春、夏、秋季時

5、：按重量比 810% 加入中和劑 BH-008 配制工作液。 冬季氣溫低時：按比重 35% 加入 TS-300 配制工作液。 春夏秋工件以中和為主；冬季以清洗為主。In the season of spring ,summer and autumn :Add Neutralizer BH-008 810% by weight to make the working solution .In winter ,when the temperature is low :Add Passivator TS-300 35% by weight to make the working solution .

6、(3) 皮膜鈍化處理槽：Passivation tank : 按重量比 1015% 加入水質調節(jié)劑 TS-300 配制工作溶液。Add Passivator 1015% by weight to make the working solution . 工作槽液的工藝參數(shù)：technic data for the Working solution liquid in the tanks :除銹除油二合一處理槽：常溫浸漬，時間：3090min , PH值w 1.5Rust removing and oil cleaning tank: soakage at the normal temperatu

7、re , time :3090min ,PH w 1.5 .中和槽：春夏秋季：PH三12，常溫浸漬時間35min ;冬季PH三9,浸漬時間35min , 溫度30 C左右。Neutralizer Tank :In the seas on of spri ng ,summer and autu mn : liquid PH PH 三 12, soakage time 35min; In winter PH 三 12, soakage time 35min. working temperature about 30 °C .皮膜鈍化處理槽：PH值三10常溫浸漬時間510min。Passi

8、vation tank :Liquid PH 三 10 . soakage time 510min.操作工藝規(guī)程：Working engineering procedure .(1) 向掛具筐內擺放鋼管工件時，盡量考慮管內溶液容易排放掉。When put pipes in the working basket , please consider that the liquid in the pipe is easy to drain out .(2) 將工件吊放到工作槽溶液中的時候，要上下吊掛數(shù)次，使管件在溶液 中上下擺動以加快除銹除油速度。When put the working box i

9、n the liquid , the box should be lift and lowedmany times in order to make the pipe luffing in the mixture , that will make the working process ofRust removing and oil cleaning much faster .(3) 工件從除銹除油槽、中和槽和皮膜鈍化槽中吊出后，都應采用雙機吊 鉤裝吊掛具架，前后分別提升下降，以排凈管內溶液。When the pipes is taking out from the working solution of rust removing and oil cleaning tank, Neutralizer Tank and Passivation tank all should be luffing many times in order to drain out the liquid in the pipe .(4) 經(jīng)常測定工作槽液的 PH 值并適當補充
