Abstract
The said inactivating agent mainly consists of dichromate, metallic chloride, nitrate and water in certain proportion. It is suitable for continuous steel-belt machine set. Using nitrate as inactivating reaction promote results in short processing period, fast desiccation, chromium content on processed plate surface being adjustable in 10-60 mg/sq.m according to technological requirement. When it is 45-50 mg/sq.m, the SST is over 96 hr.
Description
The present invention relates to the multielement reaction passivating treatment agent that a kind of electrogalvanizing steel plate is used.
The passivation treating agent that is applied to electrogalvanizing steel plate at present has two classes: a class is after electrogalvanizing steel plate at first adds the passivation treating agent of anhydrous phosphoric acid through anhydrous chromic acid salt, anhydrous phosphoric acid through the second layer adds organosilyl treatment agent processing again, (the flat 5-14790 of JP) is contained according to patent documentation, the shortcoming of the two-layer passivation treating agent of this type of electrogalvanizing steel plate is to make the passivation technology complexity, increased facility investment, the electrogalvanizing steel plate surface C r content after Passivation Treatment is at 45～62mg/m
2The time, it only is 48 hours that its solidity to corrosion (SST) 5% white rust evaluation occurs by JISZ2371, can not satisfy the solidity to corrosion requirement after the electrogalvanizing steel plate surface treatment; Another kind of is to add organic resin (as acrylamide) in the passivation treating agent, to improve its solidity to corrosion.Record and narrate according to patent (the flat 5-14789 of JP), the second layer treatment agent of this type of passivation treating agent is anhydrous chromic acid salt+organosilicon+organic resin, the passivation treating agent of this class electrogalvanizing steel plate, although solidity to corrosion has raising slightly, but the composition control of passivation treating agent is difficulty, and passivation technology is numerous and diverse, increase facility investment and energy consumption (needing redrying), limited on the unit of original tooling and implemented.
In order to overcome the shortcoming of above-mentioned electrogalvanizing steel plate passivation treating agent, developed the passivation treating agent of a kind of electrogalvanizing steel plate with multielement reaction.
The multielement reaction passivating treatment agent that electrogalvanizing steel plate of the present invention is used mainly contains dichromate+metal chloride+nitrate and constitutes.
Its major ingredient is as follows:
1.Cr
6+：0.0302～0.06711mol/L
2.Na
+：0.0604～0.13242mol/L
3.Cl
-：0.1732～0.3324mol/L
4.Fe
3+：0.04439～0.11098mol/L
5.NO
- 3：0.01242～0.0414mol/L
The electrogalvanizing steel plate passivation treating agent that the present invention is made of above-mentioned major ingredient, its pH value are 0.5～5.0, and treatment temp is 25～45 ℃, and treatment process can be that dipping adds water rinse, also can use spray after water floats, and is dry then.The advantage that the present invention gives prominence to is to utilize NO
- 3As the ion that quickens passivation reaction, easy controlling concn.In 2～10 seconds its treatment times of passivation treating agent of the present invention, the optimum drying temperature of steel plate after treatment is 60～80 ℃, also seasoning at room temperature.
The present invention compares with the two-layer passivation treating agent of aforementioned introduction, has reaction fast, and the treatment time is short, and through the electrogalvanizing steel plate surface that multielement reaction passivating treatment agent of the present invention is handled, its Cr content can be according to arts demand, at 10～60mg/m
2Between flexible, when the Cr on electrogalvanizing steel plate surface content at 45～50mg/m
2The time, (SST JISZ2371) greater than 96 hours, and has saved the energy consumption that redrying is handled to its solidity to corrosion, needn't thoroughly change original tooling.
