/ v* ]! K3 ?* aFor 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
+ O3 P3 g: K; t) @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
; |! K4 [) f6 V+ d$ p9 g" rIf  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
1 o& a: g! ~5 w( Q1 Spowder as indicated by titration.

為使鍍層正常的形成,，ALOCROM 的浴缸應(yīng)該控制在PH 1.6-2.2 之間,。 如果鍍層形成的時(shí)間比正常的時(shí)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(bǔ)充浴缸的時(shí)候,，可以添加濃縮硝酸減低PH值。開始的時(shí)候,，填充浴缸需要每4KG ALOCROM 添加100CM3的酸,；必要的時(shí)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(gè)小時(shí)才可以進(jìn)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,�,？偟腁LOCROM 濃度不能超過 14KG/1000升，這相當(dāng)于7cm 3 的滴定數(shù),。一旦設(shè)立了最佳的操作濃度,，那就要根據(jù)滴定數(shù)，少量添加ALOCROM 1200粉末來確保該濃度,。

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
