ANKOR 1126

Hard chromium electrolyte

                                                                        -------------------ANKOR 1126 硬鉻電解液

CHARACTERISTICS【簡介】

Hard chromium electrolyte with high cathodic current efficiency and good throwing power for the deposition of micro-cracked deposits with a hardness of approximately 1050 HV 0,1. ANKOR 1126 combines the good properties of conventional sulphuric acid electrolytes, i.e. only slight attack of iron and iron alloys and cathodic current efficiencies which are usually only achieved with catalysts on the basis of complexed fluorides. ANKOR 1126 is free of fluorides.硬質(zhì)鉻電解液具有較高的陰極電流效率和良好的拋擲能力，可沉積硬度約為1050 HV 0,1的微裂紋沉積。ANKOR 1126結(jié)合了傳統(tǒng)硫酸電解質(zhì)的良好性能，即只有輕微的鐵和鐵合金的攻擊和陰極電流效率，這通常只有催化劑在配合氟化物的基礎(chǔ)上實現(xiàn)。ANKOR 1126不含氟化物。

The service life of the lead alloy anodes is shorter compared to the service life in chrome plating solutions based on sulphuric acid or mixed and is dependent upon the individual operating conditions. New anodes have to be worked in as described in the Instruction Sheet MB0021 Furthermore platinized titanium anodes are recommended . Care has to be taken that they are completely covered with a lead dioxide film(brown-black layer). Only under this condition is Cr ³⁺oxidised to Cr⁶⁺.The lead dioxide film is obtained using one or more PbSn anodes together with the platinized titanium anodes or by addition of ANKOR Addition Solution PTA (see Technical Data Sheet).與基于硫酸或混合鍍鉻溶液的使用壽命相比，鉛合金陽極的使用壽命較短，并取決于個人的操作條件。新的陽極必須按照說明書MB0021中的描述進行加工。此外，建議使用鍍鉑鈦陽極。必須當心，它們完全覆蓋了一層二氧化鉛薄膜(棕黑色層)。只有在此條件下，Cr³⁺才被氧化為Cr⁶⁺。使用一個或多個PbSn陽極和鍍鉑鈦陽極或通過添加ANKOR添加溶液PTA(見技術(shù)數(shù)據(jù)表)獲得二氧化鉛薄膜。

Voltage 電壓

The required rectifier voltage depends on various factors, e.g. current density, concentration, temperature, type of electrode and electrode spacing. Average value: 6 - 12V.所需的整流電壓取決于各種因素，如電流密度、濃度、溫度、電極類型和電極間距。平均值:6 - 12V。

Rectifiers整流器

Usually 12 volt units; for high outputs 15 volt units. 通常是12伏單位;高輸出15伏單位。

Rectifiers have to be adjusted until the residual ripple is less than 5 % within the total current range. 整流器必須調(diào)整，直到剩余紋波在總電流范圍內(nèi)小于5%。

Deposition rate 沉積率

At 50 A/dm² approx.1,0 um/min chrome is deposited.

Reinforcement【補充】

For regeneration the electrolyte is maintained with Reinforcement Salt ANKOR 1126/2 and

Addition Solution ANKOR 1126/3 being added to the electrolyte ANKOR 1126 in the ratio 10 kg : 1 l.

為了使電解質(zhì)再生，將強化鹽ANKOR 1126/2和 添加液ANKOR 1126/3按10 kg: 1 l的比例添加到電解質(zhì)ANKOR 1126中。

To increase the density by 1° Be, add approx. 要增加1°Be的密度，添加約。

1.5 kg/100l Reinforcement Salt ANKOR 1126/2 as well as 0.15 l/100 I Addition Solution ANKOR 1126/3. 1.5 kg/100l強化鹽ANKOR 1126/2以及0.15 l/ 100i添加液ANKOR 1126/3。

EFFECT OF THE ADDITION SOLUTION ANKOR 1126/3添加溶液ANKOR 1126/3的效果

Too low concentrations result in milky, dull deposition. Excessive concentrations reduce the maximum applicable current density and result in dull and nodular deposition in the highest current density range. 濃度過低會導(dǎo)致乳白色、暗淡的沉積。過量的濃度降低了最大適用電流密度，并導(dǎo)致在最高電流密度范圍內(nèi)的鈍狀和結(jié)節(jié)狀沉積。

An excess of Addition Solution ANKOR 1126/3 can only be "removed" by diluting the electrolyte.

We recommend to add the solution always according to the standard value of 10 kg : 1 l. However the ratio of addition can be influenced by drag-out and recycling. After adding approximately 15 kg/100 IReinforcement Salt ANKOR 1126/2, we recommend to send us an electrolyte sample of 1 litre for analysis and adjustment.過量的添加溶液ANKOR 1126/3只能通過稀釋電解質(zhì)來“去除”。我們建議始終按照10kg: 1l的標準值添加溶液，但添加比例會受到拖出和回收的影響。在加入大約15公斤/100IReinforcement Salt ANKOR 1126/2后，我們建議寄給我們1升的電解質(zhì)樣品進行分析和調(diào)整。
