DH-60L Additive to Iron-Steel Rust Remover

This additive is use in hydrochloric acid pickling or hydrochloric-compound acid pickling of high-, midium- and low-carbon steel and some other materials. When this additive is added to the pickling liquid under different technical conditions, better results are achieved: the pickling process is quickened, acid mist is prevented, over-doing avoided, and hydrogen seepage stopped. This is a high-tech product, the most up-to-date and practical product of its kind, effective in reinforcing the material and saving energy, as well as good for environment protection and operation conditions.

1. Characteristics of the product

a)   When DH-60L is added in the hydrochloric acid pickling liquid, the rate of mist prevention may reach 80-90% according to different steel materials and pickling conditions. The evaporation of the acid is restricted, the consumption lessened. 30-40% of the hydrochloric acid is saved. In addition, using DH-60L blocks the erosion of the material, so the loss of the base may be reduced by 0.4-0.6 %. 

b)  DH-60L has its excellent properties of penetrating, dispersing and moistening. When it is added to     

  the liquid, the pickling process is sped up, the surface impurities, rust and oxide crust are more     

      easily rid of. So a clean material surface is guaranteed to pave the way of successive operations.

c)  DH-60L consists of some complex activator that can get Fe2O3 and Fe3O4 readily dissolved, and the Fe2+ and Fe3+ will be brought into new complexes. Thus the rust removing process is much quickened, and the frequency of renewing the treatment liquid is limited.

d)  DH-60L additive to pickling liquid is safe, nonpoisonous and odorless. It has a certain nice smell and is of very stable properties.

2.  Main technical norms

a) Appearance and state --- There are 2 kinds of DH-60L additives, namely, DH-60LA(initial agent) and DH-60LB(supplied agent), both being liquid between light yellow and milky white colors.

b) Physical and chemical properties

specific gravity --- 1.05 ±0.0.5

solubility --- easily dissolved, acid

PH value --- 6-7

safety in use --- nonpoisonous, non-inflammble, non-explosive

smell --- odorless, a little fragrant

erosion-resisting rate --- 98%(actual test result of DH-60LA, 99.95%)

c) Density in the treating liquid:  5%

e)   Base acids

industral sulphuric acid --- 10-15%

hydrochloric acid --- 25-45%

f)   temperature and manner of usage: normal atmospheric temperature to 40°C, pickling

g)  time duration: 5-10 minutes

3. Methods and conditions required

Prepare the liquid according to the density requirement. Normally the liquid contains 10-20% hydrochloric acid. And when the additive DH-60L makes up 5% of total amount of the pickling liquid, the result may be the best. The normal atmospheric temperature will be all right for theoperation. After a certain time, when acid mist rises or extra acid was added, DH-60LB(supplied agent) should be put in(also an amount of 5% of the total liquid).

4.       Property, package, transportation and storage

a)  property --- This product is a light yellow liquid, with no impurities or non-soluble susbstances. It can be stored for a long time without deteriorating.

b)  Package, transportation and storgae --- This product is non-poisonous, not inflammable or explosive, with no special requirements for its transportation and storage. 50kg polythene plastic container is used for its package. Package may be altered on customers’ requests.
