7. ALOCROM 1200 BATH CONTROLL
ALOCROM 1200 浴缸的控制
7.1 ALOCROM TITRATION: 浴缸滴定
a. Adjust the Alocrom bath to its normal working level with water and stir.
用水調整浴缸到正常的操作水平并攪拌。
b.Pipette 5 cm3 of the Alocrom bath into a 250 cm3 flask and dilute to about 100cm- with water. Take care that none of the solution is spilt throughout the test.
用吸管吸5 cm3 的ALOCROM 溶液到到250 cm3 燒瓶并用水稀釋到大概100CM3 注意在整個試驗過程中不能有溶液溢出。
c. Add about 1 gram of potassium iodide and agitate to dissolve.
添加約1克的碘化鉀并振搖至溶解。
d. Add about 5 cm3 of concentrated hydrochloric acid and mix. Leave to stand for about 1 minute.
添加大概 5 cm3 的濃縮鹽酸并混合，放置1分鐘左右。
e. Titrate the solution with 0.1N sodium thiosulphate until a straw colour is obtained.
用0.1N的硫代硫酸鈉滴定溶液，直到獲取淡黃色為止。
f. Dissolve about 0.5 grams of iodine indicator (Iotect) in water and add to
the flask. A blue-black colour will be obtained. Continue the titration to
the colourless end point.
在水中溶解大概0.5克的碘指示劑（LOTECT），并添加至燒瓶。或出現深藍色。繼續滴定到無色終點。
The number of cm 3 of sodium thiosulphate added is the strength titration
3
of the bath and this should be maintained at 3.3 - 4.0 cm . Add 2 kg of
3
Alocrom  1200  powder  per  1000  litres  of  bath  for  each  cm below  the
required value.

所添加的硫代硫酸鈉的cm 3數就是浴缸的濃度滴定，這應該保持在3.3-4.0 cm 3. 在要求值以下的每cm 3 ，每1000升浴缸要添加 2KG ALOCROM 1200 粉末
Refer to Section 12 - HANDLING PRECAUTIONS before opening the
Alocrom 1200 container 在打開ALOCROM 1200容器包裝前，請參考第12部分的內容—操作注意事項。

7.2 PH Controll
PH 值的控制
For correct coating formation, Alocrom baths should be operated at a pH
between 1.6 and 2.2.  If the coating takes longer to form than normal and
is lighter coloured or non-adherent, this indicates that the pH is rising and
it should be lowered by adding concentrated nitric acid when replenishing
the bath. Initially, add 100 cm3 of acid for each 4kg of Alocrom needed to replenish bath; if necessary increase the amount in 100 cm3 increments, up to a maximum of 1 litre/4 kg until consistent coatings are obtained. The amount of nitric acid added must be kept as low as possible and the maximum must be exceeded. After each addition of acid, wait for several hours before adding more acid to ensure the bath has reached equilibrium
If  preferred, the pH can usually be lowered by increasing the Alocrom
concentration rather than adding concentrated nitric acid.  To do this add
Alocrom  in  1  gram  per  litre  increments  until  consistent  coating  are
obtained. The  total  Alocrom  concentration  must  not  exceed  14  kg per
1000 litres which corresponds to a titration of 7 cm . Once the optimum operating  strength  for  a  particular  plant  has  been  established,  the  bath should be maintained at that strength by small additions of Alocrom 1200
powder as indicated by titration.

為使鍍層正常的形成，ALOCROM 的浴缸應該控制在PH 1.6-2.2 之間。如果鍍層形成的時間比正常的時間要久而且顏色比較淡或沒有粘附力，這表示PH 在上升。在補充浴缸的時候，可以添加濃縮硝酸減低PH值。開始的時候，填充浴缸需要每4KG ALOCROM 添加100CM3的酸；必要的時候，以100cm3增加量增加到 1升/4KG 的最大值。直到獲得符合要求的鍍層為止。添加硝酸的用量盡可能控制得最小。不能超出最大值。每次添加完酸，要等幾個小時才可以進一步添加以確保浴缸平衡。
最好，PH常常可以通過添加ALOCROM 濃度的辦法來降低而不是添加濃縮硝酸。為此，以1克/升的增加量添加ALOCROM，直到鍍層符合要求。總的ALOCROM 濃度不能超過 14KG/1000升，這相當于7cm 3 的滴定數。一旦設立了最佳的操作濃度，那就要根據滴定數，少量添加ALOCROM 1200粉末來確保該濃度。
8. OPERATING NOTES
8.1 PRECLEANING
Remove all grease by solvent vapour degreasing or by using Ridoline,
Novaclean or Almeco cleaner. Rinse where necessary.
通過溶劑蒸氣脫脂或使用Ridoline, Novaclean 或 Almeco 清潔劑去除油脂，必要的時候水洗。
If the oxide skin is very light no further precleaning is required.  However, if the oxide skin is heavier eg. on extrusions, heat treated sheet aluminium or cast alloys etc, it  will  normally need  removing with Deoxidiser. See Data Sheet on Deoxidisers 1, or 7/17 for details. 如果氧化皮膜很輕，不要求進一步預清洗。但是如果氧化皮膜比較重，如在擠型材，熱處理后的鋁板或壓鑄合金等上的，通常需要Deoxidiser（脫氧劑）去除油脂。有關的明細請參考Deoxidiser（脫氧劑）1、或7/17上面的數據說明書.

Copper containing alloys tend to smut in etching alkali cleaners and the copper smut should be removed by dipping the component in 10% nitric acid or Deoxidiser 7/17.  Alloys containing more than about 1% of silicon, such  as  those  commonly  used  for  die  castings,  give  a  silicon  smut  if etched  in  alkali  and  this  cannot  be removed  by  nitric  acid or  any  other practicable methods.  Such alloys are best solvent degreased and given a light etch in Deoxidiser 7/17 before the Alocrom treatment.
含有合金的銅在蝕刻堿性的清潔劑中容易變黑。銅上面的污點應該把工件浸泡在10%的硝酸或脫氧劑Deoxidiser 7/17中去除。含硅在1%以上的合金，如普遍用于壓鑄件中的那些，如果在堿性中侵蝕，會讓硅產生污點，這污點無法用硝酸或任何其他實用的辦法去除掉。在ALOCROM 處理前，這些合金在脫氧劑Deoxidiser 7/17中最好的被溶劑脫脂并造成輕度蝕刻。
8.2 ALOCROM TREATMENT
ALOCROM 處理
Immerse  in  the  Alocrom  1200  bath  for  2-5  minutes  at  18-27°C. After
removing  the  work  from  the  bath  allow  it  to  drain  over  the  tank  for  15 seconds.  This  will  avoid  unnecessary  contamination  of  the  rinse  and
reduce drag out losses.
在溫度為18-27°c 的ALOCROM 1200浴缸中浸沒2-5分鐘，從浴缸溶液中拿起工件后在槽上晾15秒，讓其流干，這可以避免洗滌水不必要的污染并減少“拖出”損耗
8.3 ALOCROM COATING CONTROL
ALOCROM 鍍層控制
Baths operating correctly give thin, adherent coatings ranging in color
from iridescent gold to golden yellow.  Typical coating weights are in the
range 0.3 to 2.0 g/m2 (30-200 mg/sq ft).
浴缸溶液如果操作正確，應該可以產生一層薄薄的、粘附在工件上的鍍層，顏色介于虹彩金色到金黃色之間。鍍層重量（涂布量）介于0.3 到 2.0 g/m2 (30-200 mg/sq ft).
If the coating does not form or is too light or too iridescent, the cause may
be one or more of the following:
如果不能形成涂層或鍍層太輕太淡，或虹彩色過于明顯，可能是以下一種或多種原因引起：
a.       The bath temperature is too low for the immersion time.浸沒時浴缸溶液溫度太低
b.       The immersion time is too short 浸沒時間太短
c.       The concentration of the bath is too low 浴缸溶液濃度太低
d.       The pH of the bath is too high 浴缸溶液PH太高。
e. Heat treatment residues or an oxide layer on the metal surface are
preventing coating formation, these can be removed with
Deoxidiser (see relevant Data Sheet for details).
熱處理后的殘留物或五金件表面的氧化層都可以妨礙鍍層形成，這些都可以用脫氧劑Deoxidiser去除（請參照相關的產品數據說明書）
f. The bath has been overheated. This can permanently upset the
chemical balance of the solution.
浴缸溶液過熱，這可以永久性的破壞溶液的化學平衡。
g. The  bath  has  become  contaminated  with  phosphates,  sulphates,
etc., from a prior cleaning bath.
浴缸溶液在之前清洗浴缸時被磷酸鹽、硫酸鹽等污染

If the coating is too heavy or dark, the causes may be one or more of the
following:
如果鍍層太重或色太深暗，可能是以下一種或多種原因引起：
a.       The bath temperature is too high for the immersion time.浸沒時浴缸溫度太高
b.       The immersion time is too long.浸沒時間太久
c.       The concentration of the bath is too high浴缸濃度太高
d.       The pH of the bath is too low. 浴缸PH值太低
If the coating is powdery, the cause may be one or more of
the following:
如果鍍層成粉狀，應該是以下一種或多個原因造成：
a.       The work has been improperly cleaned and/or rinsed. 工件沒有正確清洗
b.       The bath has become contaminated 浴缸溶液污染
c. The surface oxide has not been adequately removed. Treat with
Deoxidiser. 表面氧化物沒有完全去除，可以用脫氧劑Deoxidiser

8.4 ALOCROM BATH MAINTENANCE
ALOCROM 浴缸維護

Restore the working level of the bath regularly with water to make good
evaporation and drag-out losses.
定期用水修復浴缸的工作水平面以發揮最佳的揮發作用和拖出損耗。
If any sludge accumulates and begins to interfere with the processing, the
bath should be cleaned out.  To do this allow the sludge to settle, siphon
or  pump  the  clear  solution  into  the  emptied  rinse  tank  and  discard  the
sludge.  Wash out the Alocrom tank and return the solution.  Fill the bath
up to its operating level with water and add Alocrom to bring the bath to
its working strength.
如果有任何淤泥累積并開始影響工藝操作，應該清洗浴缸。為此，用虹吸管吸或泵入清水到空水槽里并清除淤泥，把ALOCROM 洗干凈并恢復溶液。用水填充浴缸到操作水平面并添加ALOCROM 達到工作濃度。

Alocrom baths have a very long life and for all practical purposes need
never be discarded.
ALOCROM的使用期很長，適用于所有實際用途，不需廢棄。

9. RINSING 水洗
Rinse for 15-30 seconds in clean running water.  The rinse water flowing to drain
will contain a low concentration of chromates (hexavalent chromium). A typical
figure  would  be  15  mg/l  (ppm)  Chromium (as  Cr),  and  this  may  need  effluent treatment  to  satisfy  the  requirements  of  the  Drainage  Authority. Details of a simple effluent treatment method will be supplied on request.
在干凈的流動水中清洗15-30秒，流出的洗滌水會含有低濃度的鉻（六價鉻），通常是 15MG/L(PPM) 鉻（即是Cr）,這需要作工業廢水處理以符合排污方面的有關規定。可以提供簡單的污水處理辦法的細節。
If the work it to be painted, rinse finally in deionised water, or alternatively mains
water containing Deoxylyte (see the relevant Product Data Sheet for details).  To
help dry the work this rinse can be heated to 50-70°C.  Deoxylyte in the final
rinse  counteracts  the  effects  of  any  hardness  in  the  final  rinse  water  and improves the corrosion resistance. It also acidifies the surfaces before drying
and thereby ensures good paint adhesion even under prolonged humid conditions.  Alternatively, Alocrom 1200 can be used for the same purpose.  Add
50-250 grams of Alocrom 1200 per 1000 litres of final rinse. The pH should be
3-5.  Deionised water may be required to achieve this pH.
如果工件要做進一步的噴涂，最后要在去離子水中清洗，或在含有脫氧劑Deoxylyte的水中（參照有關的產品使用說明），為幫助工件弄干，沖洗可以加熱到50-70°C。在最后清洗中的脫氧劑Deoxylyte可以抵消最后清洗水中的硬度作用，從而改善抗腐蝕作用。同時可以在干燥前酸化表面，從而確保了即使處在延長的潮濕條件下還有很好的噴涂粘附力。或者ALOCROM 1200可以用作同樣的目的。每1000升的最后清洗水添加50-250克的ALOCROM 1200。PH 值應該是3-5，為達到該PH，可能需要去離子水。
The final rinse must be kept clean and it should be renewed once a day or, for
continuous  production,  once  a  shift. Use  deionised  or  distilled  water  for  final rinse make-up if possible.
最后的清洗水必須保持干凈，并且應該每天更新一次或者，持續生產時，每班一次。可以的話，使用去離子水或者蒸餾水做最后清洗水的建浴。
10. DRYING 烘干
Air or oven dry the work.  Oven drying speeds up production and a peak metal
temperature  of  70°C  is  recommended. At  higher  temperatures,  there  may  be some loss of corrosion resistance, particularly on copper bearing alloys or where
articles are to be left unpainted.
空氣晾干或烤箱烘干，烤箱烘干可以加快生產，建議五金的最高溫度在70°C。如果溫度更高的話，可能會引起抗腐蝕作用的部分丟失。尤其是含有合金的銅件或者是那些表面處理后不用噴涂的產品
There  is  no  restriction  on  the  stoving  temperature  of  paint  or  other  organic coatings applied over the Alocrom. 對ALOCROM 處理后進行噴涂的烤爐溫度或者其他后處理的有機鍍層沒有規定

The freshly formed Alocrom coating is quite soft and care must be taken not to
damage it during rinsing and drying.  When dry, Alocrom treated parts may be
painted or put into service without further treatment.
剛形成的鍍層太柔弱必須注意不要在清洗和干燥時不要損壞，干燥后，ALOCROM 處理后的產品可能要噴涂或者無需進一步處理就投入使用。
Operators should wear cotton gloves when handling freshly treated work.
操作者處理剛表面處理好的工件須戴棉質手套。

11. REMOVAL OF ALOCROM COATINGS
ALCOCROM 的退鍍
Fresh  Alocrom  1200  coatings  may  be  removed  without  seriously  etching  the aluminium  by  immersing  in  50%  nitric  acid  or  in  the  Deoxidiser bath. Aged coating or those which have been heated are very resistant to chemical methods
of removal and an etching alkali will be necessary.
剛做的ALCOCROM 1200鍍層可以浸沒在50%的硝酸里或者脫氧劑Deoxidiser浴缸里去除鍍層，而不會明顯地腐蝕鋁材。對于那些電鍍后時間較久的或者那些加熱后的工件會對這些化學方法去除鍍層有很大的抵觸，需要用到蝕刻堿。

12. EQUIPMENT 設備
The equipment consists of:-
包括如下設備：
a. Degreasing plant with suitable rinses where required and if necessary a
Deoxidiser or Desmut tank and rinse. 除油脫脂廠房，必要時有適當的沖洗設施，脫氧或剝黑膜缸、沖洗池。
b. An Alocrom tank constructed of 18 gauge type 316 (En58J) stainless steel
or  rigid  PVC, neoprene, polypropylene,  glazed fibre glass or polythene.
Rubber,  lead,  ceramic  or  glass  are  not  suitable.  It is not usually
necessary to heat the tank but if the temperature of the shop is likely to
fall below 18°C,  a steam coil or electric immersion heater should be fitted
to the tank.  The solution deteriorates rapidly if heated above 35°C and a
thermostat  MUST  be  fitted  to  a  heated  tank. Overheating  the  Alocrom
may result in the formation of toxic fumes.
ALOCROM 浴缸用18 標準 TYPE 316 (EN58J)不銹鋼或硬PVC，氯丁二烯橡膠、聚丙烯、光滑的玻璃纖維或聚乙烯。橡膠、鉛、陶瓷或玻璃是不適合的。通常不需要加熱浴缸，但是如果工廠的溫度下降到18°以下，浴缸應該安裝蒸氣旋管或浸沒式電熱器，如果加熱到35°以上，溶液會很快變質，因此加熱的浴缸要安裝上恒溫調節器。ALOCROM 浴缸過熱的話可以形成毒煙。
The  tank  should  be  sited  in  a  well  ventilated  area  and  fitted  with  a
properly  designed  extract  system. As a guide,  air velocity  across  the

Alocrom should be about 25 m/min.  Tanks over 75 cm  wide should have
extract slots on both sides.  Typical slot velocity will be 700 m/min.
浴缸應該安置在通風良好的地方并安裝設計合適的抽排系統。作為指引，ALOCROM 的空氣流速應該在25米/分鐘左右。寬度75厘米的浴缸兩邊應該有提取槽。槽的流速700米/分鐘。
Further information on tank extract design can be obtained from 'Industrial
Ventilation' published by American Conference of Government Industrial
Hygienists (ACGIH).
有關浴缸抽排系統設計的有關信息，請參照美國政府工業衛生會議（ACGIH）發布的”工業通風”的有關內容。
c. An  unheated  water  rinse  tank  and  a  final  dilute  Deoxylyte  or  dilute
Alocrom  rinse  tank. The  water  rinse  tank  should  have  a  continuous
supply of water, a weir overflow and a draining valve; the final rinse tank
should be fitted with heating coils.
沒有加熱的水洗槽和最后稀釋Deoxylyte鈍化劑或稀釋ALOCROM 水洗槽。水洗槽應該偶連續供水、溢出和排水閥；最后的水洗槽應該裝上加熱線圈。
d. A well ventilated oven for drying the work if required.
Work  can  be  handled  on  hooks  or  in  baskets  or  tumbling  barrels.
Containers  which  are  immersed  in  the  solution  should  be  of  stainless
steel, heavy gauge aluminium or plastic coated mild steel.  Care must be
taken  to  ensure  that  the  solution  can  circulate  freely  to  all  parts  of  the work.
